Reliable Fiberglass Insulation Services for Exeter Homes and Businesses
When it comes to keeping your Exeter home comfortable through all four seasons, fiberglass insulation is still one of the most trusted solutions out there. At Foam Fellas, we’ve been helping homeowners across Rockingham County improve indoor comfort and cut down on those unpredictable energy bills.

Whether you’re in a historic colonial near the Exeter Town Hall or a newer build off Epping Road, we’ve got you covered.
Fiberglass has been around for decades, and for good reason. It’s durable, affordable, and when installed the right way, it seriously helps keep your home’s temperature steady. We’re talking less draftiness in the winter and less heat sneaking in during those humid Exeter summers.
Our team takes the time to do it right — proper coverage, snug fits around outlets and edges, and no sloppy shortcuts. That’s the difference between insulation that works and insulation that just takes up space.
What Exactly Is Fiberglass Insulation?
Here’s the simple version: fiberglass insulation is made from super fine glass fibers woven together into a fluffy material. Those tiny fibers trap pockets of air, which slows down how fast heat moves through your walls, attic, or floors. That’s the science part, anyway.
What that means for you in Exeter is fewer cold spots in your living room near the windows, and less strain on your furnace when January hits. Come July, it also helps keep that sticky humidity outside where it belongs.
We typically work with three types of fiberglass insulation:
• Fiberglass batts – These pre-cut panels fit neatly between wall studs and ceiling joists. Perfect for new construction projects or major renovations.
• Fiberglass rolls – Flexible rolls that work great in attic spaces, especially for homes with standard joist spacing.
• Blown-in fiberglass insulation – Loose fibers we blow into tricky cavities or attics with irregular framing. This stuff gets into all those hard-to-reach nooks and crannies.
Why Exeter Homeowners Choose Fiberglass Insulation
There’s a reason fiberglass has stayed popular all these years — it just works. And for Exeter residents, it offers some real, everyday benefits.
Steady Temperatures, No Surprises
The main job of fiberglass is to slow down heat transfer. That means your home stays warmer when the wind whips off the Squamscott River in December, and cooler when the sun bakes downtown Exeter in August. Your HVAC system won't have to work overtime just to keep up.
Lower Energy Bills, Plain and Simple
We hear this a lot from folks in Exeter: “I don't know where my money goes every month.” Well, if your attic's under-insulated, that's one answer. Heat rises — and without proper fiberglass insulation, it's escaping right through your roof. Proper installation means your furnace and AC run less often, period.
Budget-Friendly Without Cutting Corners
Fiberglass is one of the most cost-effective insulation options out there. If you're working within a budget — maybe you just bought a fixer-upper near the Exeter Village or you're updating a rental property — fiberglass gives you solid performance without breaking the bank. And we install it with the same care whether it's a crawlspace or a cathedral ceiling.
Quieter Home, Less Noise
Live near High Street or on a busier road in Exeter? Fiberglass insulation doesn't just stop heat — it also soaks up sound. That means fewer distractions from traffic, neighbors, or even the TV in the next room. Great for home offices, too.
Added Fire Safety
Fiberglass is naturally non-combustible. That's a big plus in any home. While no insulation makes a house fireproof, having flame-resistant materials in your walls and attic adds an extra layer of protection that you just don't get with some other products.
Built to Last for Decades
Once fiberglass is installed properly, it doesn't settle, sag, or lose its R-value over time. We've walked into attics in Exeter that were insulated twenty years ago, and the stuff's still doing its job. That's the kind of reliability we're proud to offer.
Where Fiberglass Insulation Works Best in Exeter, NH Homes
Fiberglass insulation is one of those things you don’t think about until you’re freezing in January or sweating through July. Honestly, it’s a versatile solution that works in all sorts of spots around a home or building here in Exeter. Because it comes in different forms—batts, rolls, loose-fill—it can adapt to all kinds of structural layouts and insulation needs. We’ve used it in everything from old colonials near the Exeter Town Hall to newer builds out by the Exeter River.
Attic Insulation in Exeter
Attics are probably the number one spot where heat escapes in an Exeter home. We've seen it time and again—especially in older houses around the Stratham line or near the Squamscott River. Installing fiberglass insulation up there helps keep warm air inside during those brutal New Hampshire winters and cuts down on heat buildup when the summer sun beats down on your roof. It's a simple fix that makes a huge difference.
Wall Insulation for Exeter Homes
Fiberglass batts fit neatly between wall studs, which is a common approach we take for houses in neighborhoods like Perkins Park or near the Lincoln Street School. It boosts thermal performance and cuts down on energy loss. The truth is, many Exeter homes from the '70s and '80s were built with minimal wall insulation—so adding fiberglass can really transform how comfortable your place feels.
Ceiling Insulation for Multi-Story Homes
Ceilings and floor assemblies benefit from fiberglass too, especially in those multi-story Victorians you see along High Street. Temperature differences between levels can be a pain—upstairs is stuffy, downstairs is drafty. Proper ceiling insulation helps even things out, so you're not running the heat and AC at the same time.
Basement Insulation in Rockingham County
Basements here in Rockingham County—especially in Exeter—can get damp and chilly. Fiberglass insulation in the ceiling and walls helps keep the living space above more comfortable. We've worked on basements near the Exeter Public Library and down by the railroad tracks, and it always makes a noticeable difference. No more ice-cold floors above the basement.
Insulation Upgrades for Exeter's Older Homes
Exeter has some beautiful older homes—we're talking historic places near the Bandstand or on Winter Street. But a lot of them still have that old, crumbly insulation that's barely doing its job. Upgrading to modern fiberglass insulation can seriously boost energy efficiency. We've helped homeowners in the Linden Park area cut their heating bills just by replacing outdated materials. It's one of the smartest investments you can make.
Blown-In Fiberglass Insulation for Exeter Attics
Sometimes, traditional batts just don’t cut it. That’s where blown-in fiberglass comes in. We use specialized equipment to blow loose fibers into attic spaces or wall cavities—it’s a lifesaver for those tricky spots in Exeter homes. Think about those houses on Portsmouth Avenue with those weird angled ceilings. Batts are a pain there, but blown-in fills everything perfectly.
The stuff gets into all the nooks and crannies, those tight gaps that pre-cut insulation always misses. So you get way better coverage.
Here’s what you get with blown-in fiberglass:
• More uniform insulation coverage
• Improved ability to fill small gaps and voids
• Enhanced thermal performance
• Faster installation in certain applications
We use blown-in fiberglass a lot for attic upgrades in Exeter—especially in older homes around the downtown area where the attic spaces are irregular or full of obstacles.
Why Proper Installation Matters in Exeter
Here’s the thing: even the best insulation fails if it’s not installed right. We’ve seen it happen—gaps, compressed batts, uneven coverage. It’s like having a leaky bucket. All that heat you’re paying for just slips away. In Exeter’s climate, especially with those cold snaps off the river, you need every bit of insulation to work hard.
At Foam Fellas, we take installation seriously. We’re not just stuffing batts in and calling it a day. Our team looks at each area carefully—whether it’s a cape cod near Brentwood or a ranch out by the Exeter Country Club—and picks the best method. We make sure everything’s even and snug.
Here’s what we focus on:
• Accurate insulation measurements
• Full cavity coverage
• Proper insulation thickness
• Attention to air gaps and problem areas
• Clean and efficient installation practices

Exeter, New Hampshire, with a population just over 9,000, serves as the Rockingham County seat and is known for its historic downtown along the Exeter River. The town’s economy is anchored by education (Phillips Exeter Academy), healthcare (Exeter Hospital), and a mix of small businesses, while many residents commute to Portsmouth or Boston. Given Exeter’s four-season climate—with wet springs, humid summers, and freezing winters that often dip below 10°F in January—homes in neighborhoods like The Plains or Stratham Hill face significant thermal stress.
Proper insulation is critical here because many of Exeter’s older Colonials and Cape Cods, particularly near the historic Elm Street district, lack modern air sealing and insulation. Upgrading attic and wall insulation with spray foam or cellulose helps Exeter homeowners lower energy bills during those harsh winters and keeps homes comfortably cool during the humid summers, all while protecting against moisture issues common in the region’s clay-heavy soils.
Frequently Asked Questions About Exeter
My home is in the Historic District near Phillips Exeter Academy—are there special insulation requirements I need to follow?
Yes, the Exeter Historic District Commission may have guidelines for exterior modifications on historic homes. For insulation, we often recommend interior spray foam or dense-pack cellulose that doesn’t alter the home’s exterior, improving efficiency without impacting the historic character.
With Exeter’s clay soil and high water table near the Squamscott River, how do I prevent moisture problems when insulating my basement?
Exeter’s clay soils can trap moisture against foundations. We always recommend a vapor barrier and either closed-cell spray foam or rigid foam board for basement insulation, which resists moisture and prevents mold—critical in homes near the river or in low-lying areas like the Swasey Parkway.
Does Exeter have any local energy efficiency rebates for insulation upgrades?
Yes, the New Hampshire Saves program offers rebates for insulation work for Exeter residents, typically covering up to 75% of the cost for income-qualified households. Additionally, the Town of Exeter partners with the Community Power aggregation program, which can help offset energy savings from improved insulation.
Nestled in Rockingham County with a population of around 9,500, Exeter blends historic downtown charm with pre-Revolutionary homes and newer developments near Phillips Exeter Academy. Many of the area’s older colonials and cape-style houses, including those lining the streets around the historic bandstand, lack sufficient insulation against New Hampshire’s harsh coastal winters. Our services help Exeter homeowners reduce heating costs and prevent ice dams common on sloped roofs here, ensuring year-round comfort in this tight-knit Seacoast community.
