Heat rises straight out through a thin attic. The right attic insulation keeps that warmth where it belongs - in your living rooms.
Learn More
Blown-in material fills every corner and odd-shaped space that rigid batts cannot reach, giving you even coverage without tearing out walls.

A whole-home assessment finds exactly where your house is losing energy and matches the right solution to each area.
Learn More
Old, wet, or pest-damaged insulation works against you. We remove it safely and prepare the space for a fresh, effective installation.

Cold floors in winter? An uninsulated crawl space is often the reason. We seal and insulate it so you stop losing heat through the floor.
Learn More
Walls with missing or thin insulation make every room harder to heat and cool. We add insulation without major renovation work.
Learn More
Insulation alone cannot fix air leaks. Air sealing closes the gaps around pipes, wires, and framing so your insulation can actually do its job.
Learn More
A damp, cold basement raises your energy bills and invites moisture problems. Proper insulation makes it dry, comfortable, and usable.
Learn More
Closed-cell foam is dense enough to act as a moisture barrier - ideal for coastal Long Island homes where humidity is a year-round concern.
Learn More
Open-cell foam provides excellent air sealing and sound dampening for interior walls and attics at a lower cost per board foot.
Learn More
Commercial buildings lose as much energy as homes through poor insulation. We work on offices, warehouses, and mixed-use buildings across Long Island.
Learn More
Moisture rising from the ground through an open crawl space causes rot, mold, and cold floors. A vapor barrier stops it at the source.
Learn More
We install heavy-duty vapor barriers in crawl spaces and basements to block ground moisture before it can damage your home's framing.
Learn More
Air leaking through your attic floor bypasses all your insulation. We seal every penetration - pipes, wires, light fixtures - before adding material.

Already living in your home and cannot gut the walls? Retrofit insulation adds coverage to existing structures with minimal disruption.
Learn MoreReach out by phone or through our contact form. We will ask a few basic questions about your home - its age, what areas you want insulated, and any comfort problems you have noticed. We respond within 1 business day and can usually schedule your free estimate within a few days.
A crew member visits your home and inspects the attic, crawl space, or walls you want insulated. We measure what is there, check for moisture or pest damage, and look for air leaks that need to be sealed first. You get a written quote that breaks down exactly what we recommend and why.
On installation day, the crew arrives with everything they need and completes the job in one visit for most projects. We seal air gaps first, add the insulation, and do a walkthrough with you before leaving. No mess, no surprises - just a home that holds its temperature the way it should.
We carry full liability insurance and workers' compensation on every project. Ask to see our credentials before we start - we hand them over without hesitation.
Every estimate is free, written, and itemized. You will know exactly what is included before you agree to anything. No pressure, no vague quotes over the phone.
We have been working on Long Island homes since 2017. We know the local housing stock, the coastal humidity, and what works here - because we live and work in this community.
Before we pack up, we invite you to see the completed job. We document what was installed and the depth achieved - useful for rebate applications and your own peace of mind.

We had them do the attic insulation in October and by December the upstairs rooms were warmer than they had ever been. The crew was done in one day and cleaned everything up before they left.
Michael T., Riverhead
Attic Insulation
Our crawl space was a mess - cold floors all winter and a musty smell we could not figure out. They came out, assessed it, and had vapor barrier and insulation installed within a week. The difference under our feet was immediate.
Sandra R., Southold
Crawl Space Insulation
We got three quotes for spray foam on the basement rim joists. Riverhead Insulation was the only one who explained exactly why that area matters and what type of foam made sense for our home near the water. Good price and the work looked clean.

(631) 381-4521Riverhead Insulation is based in Riverhead, NY and serves 12 communities across eastern Long Island, including Southampton, Southold, Patchogue, and Westhampton. Most estimates can be scheduled within a few days of your call, and we can often complete installation within the same week for standard attic and crawl space projects.
An attic with thin insulation traps heat from the sun and radiates it down into your top-floor rooms. Proper attic insulation blocks that heat transfer so your air conditioning is not fighting the ceiling.
Yes. Salt-laden, humid air works its way into attics and crawl spaces near the Peconic Bay and Long Island Sound. Wet insulation loses most of its effectiveness - closed-cell spray foam resists moisture intrusion in a way fiberglass batts cannot. The U.S. Department of Energy recommends moisture control as a critical part of any insulation plan - see their guidance at energy.gov
Ice dams form when heat escaping through an under-insulated attic melts snow on the upper roof, and that water refreezes at the cold eaves. Riverhead gets enough freeze-thaw cycles each winter that this is a recurring problem - the fix is sealing and insulating the attic floor, not the roof itself.
If your existing insulation is dry, intact, and pest-free, you can often add new material on top. But if it is wet, moldy, compressed, or contaminated - common in older Riverhead homes near low-lying areas - it needs to come out first. Adding insulation on top of a moisture problem hides it rather than fixing it.
Yes. NYSERDA and PSEG Long Island both offer rebates for insulation upgrades in existing homes. Some income-qualified Suffolk County households qualify for the EmPower+ program, which can cover the cost almost entirely. Ask your contractor whether your project qualifies before signing anything.
Long Island falls in a climate zone where the U.S. Department of Energy recommends attic insulation reaching a specific R-value - which typically means 13 to 14 inches of blown-in material. If you can see the tops of your floor joists, your coverage is too thin. A contractor can measure this in about 15 minutes.

If your roof is leaking or your crawl space has standing water, fix the moisture problem first. Adding insulation on top of a wet or damaged area hides the issue and creates worse problems over time. A good contractor will flag this during the assessment.
Many homes built before 1985 in Long Island were constructed with little or no wall insulation and minimal attic coverage. The materials that are there have likely settled and thinned over decades. An assessment will tell you exactly where you stand and what it would take to bring the home up to current standards.
In most cases, yes - but the savings depend on how leaky your home was before and how much of the building envelope you treat. The U.S. Energy Star program estimates that properly sealing and insulating a home can reduce heating and cooling costs by a meaningful amount.

Riverhead is the county seat of Suffolk County, sitting at the base of Long Island's North Fork where the Peconic River meets the bay. It is a town with a wide range of housing - from historic two-story homes near downtown and the Peconic River, to postwar ranches and Capes built in the 1950s and 1960s, to newer subdivisions out toward Calverton and Aquebogue. A large share of the town's homes are owner-occupied, and most of the mid-century ones have never had a serious insulation upgrade.
The Long Island Aquarium on East Main Street sits in the heart of a downtown that has been growing and improving in recent years. The area draws visitors from across Long Island, and the Route 58 corridor near Tanger Outlets is one of the busiest commercial strips in Suffolk County. Whether you live in a quiet neighborhood off Sound Avenue or close to downtown, the homes here face the same challenges - cold winters, coastal humidity, and an older housing stock that was built before today's energy standards existed.
Riverhead Insulation has been working on homes throughout Riverhead since 2017. We know the neighborhoods, the housing types common to each area, and the specific moisture and climate conditions that come with living near the North Fork. If your home is losing heat, running up energy bills, or dealing with a cold crawl space or damp attic, we are a local crew that can get to you quickly and get the job done right.
