Gaps in your attic floor let heated and cooled air pour out of your home every day. We seal those gaps in Riverhead homes so your system works less and your comfort improves.
Attic air sealing in Riverhead means finding and plugging the gaps, cracks, and openings in your attic floor that let heated or cooled air escape from your living space - most jobs on a standard single-family home are completed in one to two days, and homeowners typically notice fewer drafts and a more even temperature within the first heating or cooling season.
If your Riverhead home is more than 30 years old and has never had air sealing done, there is a strong chance your attic floor has significant leaks that have been costing you money quietly for years. Decades of settling, added wiring, plumbing renovations, and recessed lighting create dozens of small openings - each one unremarkable on its own, but together they add up to a real and measurable drain on your energy bill. Air sealing addresses those openings directly, which is why it works better than simply adding more insulation on top of them.
Attic air sealing is also the right first step before any insulation upgrade - and it pairs naturally with whole-home air sealing services that address every zone of the building envelope, from basement rim joists to the attic peak.
If your heating costs feel high compared to neighbors with similar-sized homes, and your furnace or heat pump is not obviously broken, air leaks in your attic are a likely culprit. Riverhead winters are cold enough that even moderate air leakage adds up fast on your energy bill - and the problem tends to get worse each year as gaps in older homes continue to grow.
Ice dams - the ridges of ice that form at the edge of your roof after a snowfall - are a classic sign that heat is escaping through your attic and warming your roof unevenly. Riverhead gets enough snow that this is a real seasonal concern. If you have seen ice dams or noticed water staining near your eaves or upper ceilings, your attic almost certainly has air leaks that need to be addressed.
When your attic leaks air, the rooms directly below it are the first to feel it. If your upstairs bedrooms are stuffy and hard to cool in July, or drafty and hard to heat in January, that temperature difference is often a sign that conditioned air is escaping and outdoor air is getting in through your attic floor.
Pull down your attic stairs or open your attic hatch and look around the edges. If you can feel air moving, see light coming through gaps, or notice the hatch itself has no insulation on the back of it, those are visible signs of air leakage. These are just the most obvious spots - if you can see gaps here, there are almost certainly more throughout the attic that are not visible from below.
We work inside your attic, moving carefully across the joists and applying foam or caulk to every gap we find - around light fixtures, plumbing stacks, wall top plates, knee walls, and any other opening in the attic floor. This is methodical, careful work. A thorough job means covering the hidden spots that most rushed contractors skip: the areas where interior walls meet the attic floor, where wiring bundles pass through framing, and where old renovation work left gaps that were never filled. Every sealed gap is one less path for your conditioned air to escape and outdoor air to enter.
When a project calls for both sealing and added coverage, attic air sealing is paired with insulation work - because sealing first, then insulating on top, is the order that actually delivers the results you are paying for. For homeowners who want to extend these gains to the rest of the house, our retrofit insulation service addresses walls, floors, and crawl spaces in existing homes without major disruption.
Right for most Riverhead homes - sealing all penetrations in the attic floor before any insulation is added or refreshed.
For homes where the existing insulation is thin or degraded - we seal first, then bring insulation up to current recommended levels in one visit.
For homes where the attic access point is a major source of heat loss - fitting an insulated cover or gasket to stop the air movement at that single high-loss spot.
For homeowners planning a full blown-in or batt insulation job - we seal all gaps first so the new insulation performs as it should from day one.
Riverhead sits at the base of the North Fork where the Long Island Sound and Peconic Bay meet - a climate where January lows regularly fall into the 20s and humid summers push air infiltration in the opposite direction. That combination means your attic is fighting two seasonal battles: keeping heated air inside in winter and keeping hot, humid outdoor air from pushing into your living space in summer. Homes without sealed attics work harder in both seasons, and homes in Riverhead neighborhoods built in the 1950s through 1970s were constructed before air sealing was ever part of the building process. Homeowners in areas like Aquebogue and Southold face the same conditions and the same aging housing stock.
Ice dams are a specific local concern that makes attic air sealing especially worthwhile here. When heat escapes through an unsealed attic floor, it warms the roof deck unevenly - melting snow that refreezes at the cold eaves and backs water up under shingles. Riverhead gets enough winter snow that this is a recurring problem for homeowners in older neighborhoods, not a theoretical one. Sealing the attic stops the heat from reaching the roof deck in the first place, which is the only fix that addresses the root cause rather than the symptom. PSEG Long Island also serves this area, and with electricity rates among the higher ones in the country, the savings from a well-sealed attic pay back faster here than in many other markets.
We will ask a few basic questions about your home - age, square footage, and any comfort or billing problems you have noticed. Most Riverhead homeowners hear back within one business day. We schedule an in-home visit, not a phone estimate.
A technician inspects your attic in person - checking existing insulation, identifying air leaks, and assessing how accessible the attic floor is. You will receive a written estimate explaining what work is recommended and why, with no obligation to proceed.
The crew works inside your attic, applying foam or caulk to every gap they find. Most standard Riverhead homes are sealed in one full day. You can stay home - just clear a path to the attic hatch before the crew arrives.
Before the crew leaves, they will walk you through the sealed areas so you can see exactly what was done. If your project qualifies for a NYSERDA or utility rebate, we provide the documentation you need to submit the claim.
No pressure. We will assess your attic, explain what we find, and give you a clear written quote - so you can decide with confidence.
(631) 381-4521We have been working in Riverhead and the surrounding East End communities since 2017. We know the local housing stock - the mid-century ranches, the Cape Cods, the postwar two-stories - and the specific air leakage patterns that show up in each type.
Every project starts with a written estimate that explains specifically what will be sealed, what materials will be used, and what the total cost will be. No lump sums, no surprises on the invoice, and no pressure to sign anything during the assessment visit.
We know which projects qualify for NYSERDA and PSEG Long Island rebates and can walk you through what documentation is needed. Many Riverhead homeowners reduce their out-of-pocket cost meaningfully by combining state rebates with available federal tax credits - we help you use what is available.
Before we leave, we walk you through the attic and show you every sealed area so you can see the work yourself. According to the U.S. Department of Energy, verifying completed sealing is a reasonable step - and we make it standard practice on every job.
Those four points add up to one simple thing: you know what you are getting, you can see that it was done, and you have documentation to back it up. That is what a professional attic air sealing job in Riverhead should look like.
