If you live in a high-humidity region—like much of the Northeast—you already know the toll that constant moisture can take on your home. From musty basements to moldy insulation, excess humidity creates serious challenges for energy efficiency, indoor air quality, and overall comfort. That’s where spray foam insulation really shines.
At Custom Insulation Company, Inc., we often recommend spray foam for homes and buildings located in damp or humid environments. Unlike traditional insulation materials, spray foam isn’t just a barrier against heat loss—it also creates a powerful air and moisture seal that helps prevent many of the issues common in high-humidity areas.
One of the most significant advantages of spray foam is its ability to limit moisture infiltration. High humidity can seep into your home through tiny gaps in walls, floors, and attics, especially around vents, pipes, and crawl spaces. Spray foam expands to fill these gaps, creating a seamless layer of protection that reduces the likelihood of condensation and moisture buildup—two major contributors to mold growth and wood rot.
Closed-cell spray foam, in particular, offers excellent moisture resistance. Its dense structure acts as a vapor barrier, making it ideal for below-grade applications like basements, as well as areas with poor ventilation. Unlike fiberglass or cellulose, which can absorb and trap moisture, spray foam won’t sag, mold, or degrade when exposed to damp conditions.
In addition to protecting your home’s structure, spray foam insulation also helps control indoor humidity levels by keeping unwanted outside air from entering. This makes your HVAC system more efficient and helps maintain a more stable, comfortable indoor climate year-round—even on the stickiest summer days.
Proper installation is key. Our team at Custom Insulation Company, Inc. has the training and experience to assess your home’s unique needs and apply the right type of spray foam in the right areas. We ensure every job is done correctly so you get maximum moisture control, energy savings, and long-term performance.
If you’re tired of fighting against musty odors, high energy bills, or moisture-related damage, spray foam may be the solution you’ve been looking for.

Spray foam insulation is one of the most effective ways to create a more energy-efficient, comfortable home—but like anything in your house, it doesn’t last forever. One of the most common questions we hear from Massachusetts homeowners is: “How do I know when it’s time to reinsulate with spray foam?”
If your home is drafty, your energy bills keep climbing, or rooms are unevenly heated or cooled, your insulation might be underperforming. Even high-quality spray foam can degrade over time, especially if it was installed decades ago, exposed to moisture, or applied incorrectly.
Another red flag? If your insulation is visibly shrinking, cracking, or pulling away from surfaces in the attic, basement, or walls. That means air is getting in—and your money is going out. Even newer homes may need attention if the original insulation wasn’t applied properly or was never designed to handle New England’s extreme seasonal temperature swings.
Reinsulating with spray foam can significantly improve energy efficiency, reduce HVAC strain, and boost indoor comfort—all while sealing out drafts, moisture, and allergens. It's also a smart upgrade if you're planning a remodel, adding an addition, or converting an attic or basement into livable space.
At Custom Insulation Company, Inc., we offer expert evaluations to help you determine whether your current insulation is still doing its job—or if it’s time for an upgrade. Our team uses top-quality spray foam products and proven techniques to ensure long-term results that you can feel year-round.

If you’ve ever walked from one room in your home to another and noticed a sudden drop (or spike) in temperature, you’re not alone. Uneven indoor temperatures and drafty rooms are some of the most common complaints among homeowners—especially in older homes or those with outdated insulation. Fortunately, there’s a powerful solution that can tackle both issues at once: spray foam insulation.
At Custom Insulation Company, Inc., we specialize in helping homeowners throughout Massachusetts create more comfortable, energy-efficient homes. And when it comes to fixing drafts and temperature inconsistencies, spray foam insulation is one of the most effective tools in our toolbox.
In many homes, the root cause is air leakage. Gaps, cracks, and poorly insulated areas—especially around windows, doors, attics, basements, and crawl spaces—allow conditioned air to escape and outdoor air to creep in. This not only makes your rooms feel uncomfortable but also forces your HVAC system to work harder, raising your energy bills in the process.
Even if your walls are insulated with traditional materials like fiberglass, they may not be enough to seal air leaks. That’s where spray foam shines.
Spray foam insulation expands when applied, filling even the tiniest cracks and crevices that other insulation types can’t reach. It creates an airtight barrier that keeps warm air inside during the winter and blocks heat and humidity from entering during the summer.
This means your home maintains a consistent, even temperature from room to room. Drafty bedrooms, chilly living rooms, and stuffy upstairs areas can all be transformed into spaces that feel just right, all year long.
Spray foam also works as a moisture barrier, which helps reduce the risk of mold, mildew, and allergens — especially in basements and attics where drafts are common.
Not only does spray foam make your home more comfortable, but it can also:
At Custom Insulation Company, Inc., we’ve helped countless homeowners across Central Massachusetts upgrade their homes with professional spray foam installation. Whether you're dealing with drafty rooms, inconsistent temperatures, or simply want to make your home more energy-efficient, we’re here to help.

When summer hits New England, so do high electric bills and uncomfortable indoor temperatures. If your home still struggles to stay cool despite cranking up the AC, the problem may not be your HVAC system — it could be your insulation.
At Custom Insulation Company, Inc., we help homeowners take control of their energy use with spray foam insulation — a powerful solution that does more than just insulate. In fact, it’s one of the most effective ways to stay cool and cut costs during the summer.
Unlike traditional insulation, spray foam expands to fill gaps, cracks, and crevices, creating a tight seal that blocks out hot, humid air. This air sealing effect is key in the summer, where even the smallest leaks can let in heat and force your AC to work overtime.
By keeping the cool air inside and the hot air out, spray foam allows your cooling system to run more efficiently — and your energy bills to drop.
Benefits of air sealing in summer:
Solar gain — the increase in temperature from sunlight streaming through your roof and walls — can turn attics into ovens. Spray foam insulation minimizes solar heat gain, especially in attics, crawl spaces, and exterior walls.
By reflecting and resisting heat transfer, spray foam helps:
Most of our customers report a 20-40% reduction in cooling costs after installing spray foam insulation. It’s not just about comfort — it’s a long-term investment that pays for itself through energy savings.
Don’t let another summer drain your wallet or your AC. Let Custom Insulation Company, Inc. show you how spray foam insulation can transform your home into a cooler, more efficient space.

As awareness about climate change grows, many homeowners and businesses are looking for ways to reduce their environmental impact. One highly effective strategy is improving your building’s energy efficiency—and spray foam insulation is a powerful tool to help you do just that.
At Custom Insulation Company, Inc., we specialize in spray foam insulation that not only keeps your home or facility comfortable year-round but also plays a significant role in lowering carbon emissions. Here’s how spray foam can help shrink your carbon footprint:
Spray foam insulation creates an airtight seal in walls, ceilings, and crawl spaces, preventing heated or cooled air from escaping. This dramatically reduces the amount of energy your heating and cooling systems need to maintain a comfortable temperature. Since much of the energy used in buildings comes from fossil fuels, cutting your energy demand directly translates into fewer greenhouse gas emissions.
Unlike traditional insulation materials, spray foam also stops air infiltration—a major cause of energy loss in older buildings. By filling cracks and gaps that would otherwise let outdoor air sneak in, spray foam keeps your indoor environment stable and efficient. This means your HVAC system runs less often, reducing wear and energy consumption.
Another environmental benefit is the longevity of spray foam insulation. Because it doesn’t sag or settle over time like fiberglass or cellulose, spray foam maintains its performance for decades. This reduces the need for replacement or additional insulation, lowering waste and resource use over the life of your building.
At Custom Insulation Company, Inc., we use eco-conscious materials and cutting-edge application techniques to maximize both efficiency and sustainability. Upgrading your insulation with spray foam is a smart step toward a greener home and a healthier planet.

Older homes have character, charm—and often—air leaks, drafty rooms, and sky-high energy bills. At Custom Insulation Company, Inc., we specialize in helping homeowners bring their historic or aging homes up to modern energy-efficiency standards without sacrificing their unique appeal. One of the best solutions? Spray foam insulation.
Spray foam is incredibly versatile, making it ideal for retrofitting insulation in hard-to-reach or problem-prone areas. Here are the best places to use spray foam insulation in an older home:
Attics are one of the biggest sources of energy loss in older homes. Spray foam can be applied directly under the roof deck or between rafters to create a tight thermal seal. This not only prevents heat loss in the winter but also keeps hot air out in the summer.
Pro tip: Spray foam helps regulate temperature and prevents ice dams in colder climates.
The rim joist—the area where the foundation meets the wooden structure—is a common source of drafts and moisture infiltration. Spray foam seals this vulnerable gap, helping to improve comfort and prevent mold growth.
Bonus: Helps keep basements drier and more comfortable year-round.
Older homes often lack adequate wall insulation. Spray foam can be injected into wall cavities through small holes, making it a minimally invasive way to upgrade insulation without major demolition.
Result: Improved indoor comfort, less outside noise, and better energy savings.
Crawl spaces are notorious for bringing in cold air and moisture. Closed-cell spray foam insulation acts as both a vapor barrier and an insulator, protecting your home from below.
Tip: Combine spray foam with crawl space encapsulation for best results.
In Cape Cod or bungalow-style homes, knee walls (short walls under sloped ceilings) often have little to no insulation. Spray foam seals these small, oddly shaped spaces efficiently.
Why it matters: Helps prevent uneven room temperatures upstairs.
Even if the rest of your home is insulated, small gaps around windows, doors, and pipe entries can lead to major heat loss. Spray foam expands to fill these gaps completely, stopping air leaks cold.
Result: Less draft, lower utility bills, and a cozier living space.
Older construction wasn't designed with modern insulation in mind. Unlike traditional materials like fiberglass or cellulose, spray foam expands to fill gaps, seals air leaks, and adds structural strength. It's also ideal for irregular spaces and tight areas that are common in older buildings.
Retrofitting an older home with spray foam insulation requires precision and experience. At Custom Insulation Company, Inc., we’ve been helping homeowners across Massachusetts and beyond upgrade their comfort and energy performance for decades.

When most homeowners think about insulation, they think about comfort and energy savings. But did you know the right insulation can also help you breathe easier and live healthier? At Custom Insulation Company, Inc., we believe your home should be a sanctuary — and spray foam insulation plays a key role in making that happen.
Spray foam insulation forms an airtight seal that reduces the amount of outdoor pollutants, allergens, and dust entering your home. Unlike traditional fiberglass insulation, spray foam doesn’t leave gaps or allow air to leak in, keeping airborne irritants where they belong — outside.
Fewer allergens in the air = easier breathing for everyone, especially those with asthma or allergies.
Spray foam doesn’t just insulate — it also acts as a moisture barrier. By sealing cracks and crevices, it helps prevent humid air and condensation from getting into walls, attics, and crawl spaces. This is crucial for avoiding mold growth, which can cause respiratory issues and long-term structural damage.
A quieter home is a more peaceful home. Spray foam helps to dampen sound by filling in gaps where noise typically travels. Whether it’s outside traffic or room-to-room noise, spray foam adds an extra layer of soundproofing comfort.
Because spray foam tightly seals all the nooks and crannies, it creates a barrier that’s tough for insects and rodents to get through. That means fewer unwanted guests in your home — and less risk of contamination or health hazards from pest infestations.
By eliminating drafts and hot/cold spots, spray foam helps maintain stable temperatures throughout your home. Not only does this boost comfort, but it also reduces the strain on your HVAC system — promoting better air circulation and reducing indoor humidity swings that can trigger allergies.
At Custom Insulation Company, Inc., we specialize in professional spray foam installation that enhances comfort, saves energy, and supports better health. Whether you’re building new or upgrading your current insulation, we’re here to help you make smart, lasting improvements.
