Heat escaping through attic gaps drives up your bills and lets cold drafts in. We seal every opening so your home holds heat the way it should.
Attic air sealing in Altoona means finding every gap, crack, and opening in your attic floor and plugging them with foam, caulk, or weatherstripping, most jobs are finished in a single day with no disruption to your living space.
Most homeowners think insulation is the main fix for a cold, drafty house. But insulation slows heat transfer - it does not stop air from moving freely through gaps around light fixtures, plumbing pipes, and wall tops. In Altoona, where the heating season runs six months and older homes are full of unintentional openings, sealing those gaps makes a bigger difference than adding more insulation on top of them. Think of it as weatherstripping for your ceiling.
Attic air sealing is a natural partner to whole-home air sealing services, which addresses other areas like rim joists and wall penetrations. Many homeowners also pair this work with retrofit insulation - sealing first, then adding insulation on top, which is the correct order and the one that delivers lasting results.
If your gas or electric bills climb sharply from October onward and stay high no matter how much you adjust the thermostat, your attic is a likely culprit. Altoona's long heating season amplifies this effect - a leaky attic that might cost a homeowner in a milder climate a modest amount extra could cost you significantly more. If your bills feel out of proportion to the size of your home, the attic is worth investigating.
If the upstairs bedrooms or the room directly below your attic are noticeably colder than the rest of the house in winter, air is almost certainly moving between your living space and the attic. This is especially common in Altoona's older homes, where ceiling framing leaves gaps that were never sealed. You should not need to pile on extra blankets in a room that has a working heating vent.
The attic access panel is one of the most common air leak points in any home. If you stand near it on a cold Altoona winter day and feel cold air coming down, or if you can see light around the edges, that opening is costing you money every day. This is one of the easiest fixes a contractor can make and one of the most commonly overlooked.
If you saw ridges of ice building up along your roof edge or icicles forming from your gutters during a cold snap, that is a classic sign of heat escaping through your attic and melting snow on the roof. Meltwater runs down and refreezes at the cold eave, sometimes backing up under shingles and causing interior leaks. Altoona gets enough winter precipitation for ice dams to be a real, recurring problem.
We work systematically from one end of your attic to the other, sealing every penetration we find - recessed light fixtures, plumbing stacks, electrical wire runs, wall top plates, and the attic hatch itself. Depending on the size and type of each gap, we use two-part spray foam, caulk, or rigid foam board with taped edges. We move or temporarily lift existing insulation to get at the attic floor, then replace it when the sealing is done. If your home also needs new or additional insulation, we can pair this work with our full retrofit insulation service, which adds the right R-value on top of a properly sealed attic floor.
For homeowners who want a broader approach to energy efficiency, our air sealing services extend beyond the attic to include rim joists, basement band boards, and other areas where conditioned air leaks out of the building envelope. Addressing all of those points together produces a more significant improvement than any single area alone.
The right starting point for most Altoona homes - every penetration in the attic floor sealed with foam or caulk before insulation is replaced.
Pull-down stairs and simple hatches are among the worst air leak points in older homes - a quick, targeted fix that often produces immediate results.
The complete solution for homes that are both leaky and under-insulated - seal the gaps first, then add insulation to the correct depth for Altoona's climate.
For homeowners who want every air pathway addressed - attic, rim joists, basement, and wall penetrations - treated as a single connected system.
Altoona sits in Blair County in the Allegheny Mountains, where average January temperatures drop into the low 20s and the heating season runs from October through April - roughly six months of your furnace working to keep up. A large share of the city's housing was built in the early-to-mid 20th century, when energy efficiency was not a design priority and the framing techniques of the era left wall cavities open to the attic. Decades of settling have added more gaps around pipes, wires, and fixtures. The result is that many Altoona homes have attics that act as a drain on every dollar spent on heat.
The combination of cold winters and the region's tendency toward humid summers also creates real moisture risk. When warm indoor air leaks into a cold attic in winter, it condenses on the wood framing - and over years, that leads to dark staining, mold, and rot that can be expensive to fix. We work with homeowners throughout the area, including in Hollidaysburg and Duncansville, where older housing stock and the same mountain climate make attic air sealing just as important as it is in Altoona proper. The work qualifies for federal tax credits and utility rebates through programs available to Pennsylvania homeowners, which can meaningfully reduce your net cost.
We ask a few basic questions - the age of your home, whether you have noticed drafts or high bills, and whether you have existing insulation in the attic. This helps us come prepared with the right materials. You will hear back within one business day to schedule a no-cost site visit.
We go into your attic and look at what is there - how much insulation exists, where the gaps are, and how accessible the space is. You get a written estimate that explains exactly what we found and what we plan to do. We will not pressure you to decide on the spot.
Clear the area around your attic access point and move anything stored directly below the hatch. You do not need to leave the house, but expect some noise from the crew moving around overhead. Most jobs in a typical Altoona home are done in four to eight hours.
The crew lifts existing insulation, seals every gap they find, then replaces the insulation and cleans up. We walk you through what we did - with photos if possible - and let you know whether adding more insulation on top is recommended, without pressure.
Free estimates, no pressure. We come to you, assess the attic, and give you a written quote you can take your time with.
(814) 552-1335Most of Altoona's housing stock dates from before World War II, and homes built in that era have framing details and materials that newer contractors are not always prepared for. We work in these houses regularly and know where the hidden leak points are - wall cavities open to the attic, original plaster ceilings with settled cracks, and recessed fixtures that were never designed to be airtight.
A thorough job means sealing the attic hatch, the tops of interior walls, every pipe and wire run, and every recessed light - not just the gaps you can see from a quick look. We document our work with photos before insulation goes back so you have a record of what was done and can verify the scope.
PPL Electric Utilities and Peoples Natural Gas both offer rebates for qualifying energy efficiency work through Pennsylvania's Act 129 program, and a federal tax credit is currently available for qualifying air sealing work. We document jobs properly so you can claim what you are entitled to. Learn more at ENERGY STAR.
Your written estimate spells out exactly which areas will be sealed, what materials will be used, and the total cost. If we find something during the work that changes the scope, we tell you before we proceed. You are never handed a higher invoice than the number you agreed to.
Altoona homeowners choose us because we treat the job as a complete system, not a single isolated task. Proper attic air sealing done right - with every penetration addressed and the work documented - is what produces real savings on your heating bills and real protection for your home.
