Your Home Might Have A Dew Point Problem.

Anyone who has been in the construction industry for a while has heard the phrase – “you don’t want to build it too tight.” This is a reference to how buildings used to dry out, BEFORE air conditioning and insulation. Some still refer to allowing your home to breathe, but we completely changed how we build from balloon framing to platform framing, from using windows to catch a breeze to cool your home to mechanical systems that filter, clean the air, and cool your home. Your house no longer needs to breathe through random gaps in the exterior thermal envelope. It needs to be as tight as you can make it, with a proper ventilation system to complement the heating and cooling system.

Architects and builders who understand building science work to protect your home and the indoor air quality problems that might occur if you “let your home breathe.” In our mixed humid climate, one of the biggest problems could be dew point. This is the exact temperature at which airborne moisture transitions from gas to liquid. If that conversion happens inside a wood-frame wall, you have a recipe for mold, rot, and potentially structural failure.

Achieving an efficient, healthy, and resilient home requires understanding how to avoid some common construction mistakes.

Air Leakage

Air leakage is the highway for moisture transport through your thermal envelope. In our mixed humid climate, on a hot, humid day, that moist air wants to push inside your air-conditioned home. In the winter, warm air escapes to the dry cold air. Your home is always trying to reach equilibrium with the outside air. Air pressure forces movement through any cracks around plumbing, electrical outlets, framing, doors, and windows. It carries gallons of water vapor along with it. When this air hits a cold surface inside the wall cavity, it instantly hits the dew point and becomes liquid.

Insulation

Not all insulation works the same, and not all insulation can be used for all wall
assemblies. We often use open-cell spray foam because it is airtight and vapor
permeable. Closed-cell spray foam looks very similar, but it is a vapor barrier. Using this product in a wall above grade can work, but you must make sure it is done exactly right. If it pulls away from framing, allowing even the smallest leak, you could end up with a dew point issue. Also, if you use a vapor barrier and there is a liquid leak in the wall, you might not find it until you have a much larger problem. Using fiberglass batts and cellulose can also work, but the air sealing process is labor intensive and often does not last as long.

Vapor Barriers

We don’t want a vapor barrier in our climate due to the vapor drive that happens in different directions in the different seasons. Adding a vapor barrier can stop airflow on the cool surface you are trying to protect. Using the right vapor permeable solutions allows vapor to pass through the material while your HVAC system works to dry out the air to further protect your walls. Did you know that OSB, some paints and wallpaper, and many house wraps are vapor barriers?

A healthy, durable, comfortable home with good indoor air quality controls the dew point. You have to have the right HVAC system and fresh air as part of the holistic solution. Focusing on proper air sealing, insulation location and values, and HVAC can solve the challenges that many modern homes face of high humidity, mold, and rot.

When the Rain Comes In: How to Protect Your Home from Flooding and Water Damage

by Charles Hendricks | May 27, 2026 | architecture, resources

Heavy rain can turn a peaceful storm into a homeowner’s nightmare. Whether it’s water pooling around the foundation, a leaking basement, or flooding caused by overwhelmed drainage systems, moisture intrusion can quickly lead to structural damage, mold growth, and costly repairs.

While no home is completely immune to severe weather, thoughtful planning, preventative maintenance, and resilient design strategies can significantly reduce the risk of water damage.

Protect Vulnerable Areas Inside the Home

Basements and Crawlspaces

Basements are particularly vulnerable during prolonged rainfall. Warning signs of moisture issues may include:

Damp or musty odors
Water stains on walls or flooring
Cracks in foundation walls
Increased indoor humidity

Installing sump pumps, vapor barriers, or waterproofing systems may help reduce future risk, especially in older homes.

Doors, Windows, and Roofing

Wind-driven rain can expose weaknesses in a building envelope. Inspect:

Window and door seals
Roof flashing
Shingles and roof penetrations
Exterior caulking and siding joints

Small openings can become major sources of moisture intrusion over time.

What to Do If Water Enters Your Home

If flooding or water intrusion occurs, acting quickly matters.

Prioritize safety first — avoid standing water near electrical systems.
Stop the source if possible — whether it’s drainage overflow, a roof leak, or groundwater entry.
Remove water quickly — use pumps, wet vacs, or professional mitigation services.
Dry materials thoroughly — moisture trapped in walls, flooring, or insulation can lead to mold within 24–48 hours.
Document damage for insurance purposes.

Even minor water events deserve attention. Hidden moisture can compromise materials long after surfaces appear dry.

Designing for Resilience

As weather patterns continue to bring more intense rainfall events, resilient home design is becoming increasingly important.

Thoughtful strategies—such as improved grading, elevated materials, durable exterior assemblies, and smarter stormwater management—can help homes better withstand heavy weather while protecting long-term investment.

The best time to address water issues is before the next storm arrives.

May Series: Anatomy of a Custom Home

by Charles Hendricks | May 21, 2026 | architecture, Charlottesville, Custom Home, Harrisonburg Architect, Interior Design, resources, Roanoke Architect

Anatomy of a Custom Home: How design Emerges from Land, Process, and Detail

Every custom home begins long before a line is drawn. It begins with its slope, light, edges, and constraints and evolves through a sequence of decisions that gradually transform raw site conditions into a fully realized place of living.

This May series, Anatomy of a Custom Home, breaks that journey into its essential stages. Rather than treating design as a single act, it reveals it as a layered process where each step informs the next, and every detail carries forward the logic of what came before.

The Site: Where Everything Begins

The land is never neutral. It dictates orientation, frames views, suggests circulation, and sets the emotional tone of the home. Before form or style, we study how the site behaves, how it receives light, how it drains, how it opens or resists. The design begins by listening.

Concept Sketching: Where Ideas Begin to Take Shape

Early sketches are less about precision and more about interpretation. They translate site conditions into spatial ideas: massings, thresholds, voids, and relationships. This is where intuition meets analysis, and where the first version of “home” begins to emerge.

Flow & Function: Floor Plan Logic

A strong home is organized around how life actually moves. Floor plan logic establishes hierarchy, adjacency, and rhythm. Public and private zones are clarified, circulation becomes intentional, and spaces begin to support daily rituals rather than interrupt them.

Windows & Orientation: A Natural Light Strategy

Light is one of the most powerful design materials. Window placement and orientation determine not only how a home looks, but how it feels throughout the day. We design with sun paths in mind, capturing warmth, controlling glare, and shaping the atmosphere.

Framing the Vision: Structure Planning

Structure is often invisible in the final experience of a home, but it defines what is possible. This phase aligns architectural ambition with engineering clarity, ensuring that open spans, cantilevers, and volumes are both expressive and buildable.

Texture & Tones: Material Conversations

Materials give the home its voice. Whether natural stone, timber, plaster, or metal, each surface contributes to a broader sensory language. Here, durability, aging, and tactile quality are considered alongside aesthetics and cohesion.

Room Configurations: Interior Flow

Beyond the floor plan, we consider how rooms feel in sequence. Transitions matter as much as destinations. A well-configured interior creates moments of compression and release, openness and intimacy, guiding experience without forcing it.

Patios, Porches, Landscapes: Outdoor Integration

A home does not end at its walls. Outdoor spaces extend living areas and connect architecture to the environment. These thresholds: porches, courtyards, terraces, mediate between built form and landscape, anchoring the home in place.

Millwork, Finishes, Fixtures: Final Details

Details are where intention becomes tangible. Built-ins, hardware, lighting, and finish selections refine the character of the home. These elements may be small in scale, but they carry the weight of daily interaction.

The End Result: The Finished Home

A completed home is not just a composition of parts, it is a synthesis of decisions made across time. When successful, it feels inevitable, as though it could not have been arranged any other way. It reflects not only design intent, but the life it was designed to hold.

The Architect’s Guide to a Spring Reset: Beyond the Broom

by Lindsey Kohler-Austin | Mar 18, 2026 | community, Indoor Air Quality, Not used, resources

As the sun begins to linger a little longer over the Blue Ridge and the first hints of green emerge in the Shenandoah Valley, our focus naturally shifts outward. Here at Gaines Group Architects, we believe a home is a living system—one that breathes, protects, and evolves with the seasons.

While “Spring Cleaning” usually conjures images of junk drawers and dusty baseboards, we like to view the vernal equinox as a vital moment for home stewardship. It’s the perfect time to ensure your sanctuary is performing efficiently, sustainably, and beautifully for the warmer months ahead.

1. High-Performance Hygiene: Check Your Seals

In our region, the transition from winter’s bite to spring’s humidity can be tough on a building’s envelope.

The Window Audit: Don’t just Windex the glass; inspect the tracks and weatherstripping. Dirt buildup can prevent a tight seal, letting your expensive conditioned air escape.
Airflow Integrity: Replace your HVAC filters. After a winter of closed doors and running furnaces, a fresh filter is the simplest way to improve your indoor air quality. Remember, the air leakage in your home might actually be making it dirty by pulling dust and allergens from your attic into your living spaces.

2. Protecting the Valley’s Heritage

Many of our favorite projects involve historic Harrisonburg gems. If you live in an older home, Spring is the season for a “check-up”:

Masonry & Mortar: Walk the perimeter of your home. Look for “spalling” (flaking brick) or cracked mortar caused by the winter freeze-thaw cycle. Addressing these small gaps now prevents significant water damage later.
Gentle Restoration: When cleaning original wood or stone, skip the harsh chemicals. We advocate for pH-neutral, eco-friendly cleaners that preserve the patina of historic materials rather than stripping them.

3. Water Management: The Architect’s Priority

Architecture is often in a battle against water. To keep your foundation dry and your basement healthy:

Gutter Cleaning: Falling debris from winter storms can clog your drainage system. Ensure your gutters are clear and, more importantly, that downspouts are directing water at least five feet away from your foundation.
The Grading Check: Take a look at your flower beds. If the soil has settled and is sloping toward the house, spring is the time to regrade it to shed water away from your living space.

4. Biophilic Refreshes

A “clean” home should also be an inspiring one. As the Valley blooms, bring that energy indoors:

Lighten the Load: Swap heavy winter drapes for breathable linens. This doesn’t just change the look; it changes the thermal gain of your rooms.
Indoor Air Gardens: Visit the Harrisonburg Farmers Market for native plants. They act as natural air purifiers, reinforcing the “biophilic” connection between our built environment and the natural world.
When choosing supplies for your spring refresh, opt for No-VOC options. We’ve often asked, ‘Is your home making you sick?‘—and reducing chemical off-gassing from cleaners and paints is the best place to start.

Stewardship is Design in Action

Spring cleaning isn’t just a chore—it’s an investment in the longevity of your home. By treating your house as a high-performance system rather than just a collection of rooms, you ensure it remains a place of comfort and sustainability for years to come.

Need a hand reimagining your space for the new season?

Whether it’s a sustainable renovation or a custom new build, we’re here to help you design a home that works as hard as you do.

What to Know Before Hiring a Contractor

by Charles Hendricks | Nov 10, 2025 | resources

When you’re investing in a renovation or construction project, choosing the right contractor is one of the most important decisions to make. As architects, we have seen projects delayed, budgets stretched, or results below expectations due to contractor issues that could’ve been prevented. To help our clients navigate this, here’s a practical guide to hiring a contractor — with key pointers from the Virginia Department of Professional and Occupational Regulation (DPOR).

Rule 1: Use a Licensed Contractor, and Verify It.

One of the first rules is: deal only with licensed contractors. Virginia law requires that contractors meet state competency and licensing standards.

Even if a person claims to be “just doing side jobs,” unlicensed work may mean you have limited legal recourse if something goes wrong.

Before you move forward:

Check the license status (and whether there have been disciplinary actions) via the DPOR’s license lookup tool.
Confirm that the contractor is licensed for exactly the kind of work you’re hiring for (e.g. general contracting, plumbing, HVAC, specialty work).

Rule 2: Get Multiple Written Estimates & Ask Questions

Don’t rely on just picking the contractor with a great reputation: meet with them and get to know their priorities. Different contractors have different skill sets and strengths. You need to make sure your contractor aligns with your vision for the project. Ask them how they pick their sub-contractors. You want them to get multiple estimates from trusted partners.

While comparing contractors, dig deeper:

Visit a current project and talk to their current clients.
Ask the contractor to explain how they handle communications, schedule, and questions that arise during the construction phase.
Beware of a builder that has never seen a challenge during construction. You’ll want to hear from them how they deal with the challenges, because in construction, there are always challenges.

Rule 3: Insist on a Detailed, Written Contract

Verbal agreements are risky. DPOR reminds homeowners that licensed contractors are required by law to provide a written contract for residential work, signed by both parties.

A solid contract should include:

- The full scope of work (what’s included, what’s excluded)
- Start and end dates (or schedule with milestones)
- Payment schedule tied to completed work (not just arbitrary dates)
- Any warranties or guarantees
- How change orders will be handled
- What happens in the event of delays, disputes, or termination
  
  Make sure all promises, guarantees, and warranties are spelled out in writing — don’t trust oral statements.

Rule 4: Limit Your Upfront Payment & Tie Payments to Milestones

A red flag is when a contractor asks for large sums up front. DPOR suggests that a reasonable down payment should be no more than 10% or $1,000, whichever is less — unless the project requires custom or preordered materials, in which case up to 30% might be justifiable.

Also, divide subsequent payments over project milestones — each payment only issued after a defined portion of the work is satisfactorily completed. Don’t pay in full until the project is completed to your satisfaction and all documentation is turned over.

Rule 5: Be Alert to Warning Signs & Scams

DPOR outlines several “tip-offs” indicating possible trouble:

Door-to-door solicitations (remember, you have a three-day right to cancel a contract signed in your home)
Claims of leftover materials from another job
High-pressure sales tactics (“you must decide right now”)
Requests for full payment before work starts
Only accepting cash or untraceable payment forms (e.g. Venmo, etc.)

If you notice any of these behaviors, proceed cautiously or walk away.

Rule 6: Ask for References, Photos, and Proof of Insurance

Beyond the basics above:

Request recent project photos, ideally in the same style or scope as yours
Ask for references (other clients) and follow up
Confirm that the contractor carries liability insurance and worker’s compensation, and request certificates of insurance

If your project requires building permits or inspections, verify the contractor has done that before — and that they will handle it properly

Rule 7: Understand How Change Orders & Delays Work

Changes are almost inevitable. Be sure your contract states:

How change orders must be handled (written, approved, priced)
Whether extra time will be allowed for changes
What happens when delays (weather, supply chain, permit holdups) occur

This clarity helps prevent disputes later.

Rule 8: Document Everything & Maintain Communication

Keep a project file:

Copies of the contract, any change orders, subcontracts, invoices
Photos taken before, during, and after work
Written correspondence (emails, texts)
Weekly or regular progress meetings/agendas

Good communication helps ensure transparency and gives you evidence if disagreements arise.

Rule 9: Understand Your Legal Rights in Virginia

Because the contractor is licensed through DPOR, certain consumer protections apply. If things go wrong:

You may check for past disciplinary actions using DPOR’s license lookup tool.
You can file a complaint with DPOR (if licensed)
For contract disputes, your written contract and documentation serve as your principal recourse

As architects, we have seen the consequences when contractors are hired without due diligence: design intent is diluted, structural or code compliance errors, cost overruns, and definitely frustration. A well-selected contractor who understands your goals, communicates clearly, and honors contracts is essential to turning architectural visions into reality.

Economic Growth in the Shenandoah Valley

by Charles Hendricks | Oct 13, 2025 | Charles Hendricks, citizen architect, community, Leadership, Local Leaders, resources

Economic growth that is done in an intentional and healthy way is critical for the overall long-term health of our communities. I have volunteered time to the Shenandoah Valley Partnership for over a decade to help our local business community thrive. This organization brings together local government, businesses, and educational institutions to help grow our community. Often the first stop for businesses looking to locate in an area with an outstanding quality of life, like the Shenandoah Valley, SVP is a key resource for our future. In order to attract the high paying jobs that will keep our communities healthy, we need the work being done by Jay Langston and his team. They travel the country telling our story, build out resources that local government can use to attract potential new businesses, and find resources to help existing businesses thrive.

This past week I attended a construction industry round-table where a large group of local leaders discussed challenges and opportunities ahead. SVP was the catalyst for bringing this conversation together and allowed the experts in the industry to meet and talk about the future of the valley. Also last week I was able to attend a discussion about the energy industry in the valley. Dr. Jonathan Miles from James Madison University was able to talk about clean energy options that are affordable, reliable, and available now for industry. The panel discussed the need for long-range innovative planning and thought as they strive for a resilient energy grid. As we look at the severity of storms that now come up the coast and have hit communities just south of us, it is good to have these conversations in advance of having to respond to an emergency.

I am excited about the future of the valley and “energized” by the work that SVP is doing to provide dialog between parties to better the entire valley. Their motto that “a rising tide raises all ships” is exactly what we need to cut through the political chatter and plan for a better and healthier future for all. The innovative leadership at SVP is guiding us into a strong business future and working hard to attract the right businesses for the valley. Collaboration is the key here in the valley as that is a quality that does not always exist between localities in other parts of the country, and something companies looking for a new home want to see. Here in the valley we have groups that might not agree on everything come together and agree on the things that matter to move our community forward, what a gift to future generations.
