Does my San Angelo house need air sealing?
Air sealing services in San Angelo, TX find the gaps where air leaks in and out of your house, mostly through the attic floor, and close them so your rooms hold the temperature you're paying for.
Most calls start with a room over the garage that won't cool, an upstairs that runs hot or a power bill that keeps climbing even after somebody added insulation. That last one usually means the gaps underneath were never closed, so the new insulation is sitting in a draft. The price and the schedule mostly come down to how many openings are up there, how hard your attic is to get into and whether something has to be fixed before we seal. I'll look at your attic and give you your own figure at the estimate, usually before I leave.
How we handle air sealing, in order
Drafty rooms, rooms that won't match and dust trails under the attic tell me where to start looking, so I go up and follow them to the leaks around can lights, pipes, wires and the attic hatch. Safety comes before any sealing, so if you've got a gas appliance that vents on its own, we get it tested before and after the work. We check the attic's ventilation next, because soffit, ridge and gable vents and combustion air ducts are there to move air and they stay open. Then our crew seals the attic floor with caulk for small cracks, one-part spray foam for bigger gaps and rigid blocking over large openings, and only after that does any insulation go on.
Air sealing often turns up other work. If the cold floors come from below rather than the attic, basement insulation closes up that side of the house. Where you want the seal and the insulation in one layer, closed-cell foam insulation, a dense foam that blocks moisture, does both in one pass.
Seal the gaps, then top up
This suits most houses, where the ducts sit below the ceiling and the old insulation is dry but thin. We seal the openings, then add blown-in insulation, loose fill blown through a hose, at full depth out to the edges, and it usually comes out cheaper than foam.
Foam when the ducts live up there
If your ductwork runs through the attic, foam is usually worth the extra cost because it seals the air and insulates in the same layer. I'll tell you which way your house needs at the estimate, and if it doesn't need foam, I won't sell it to you.
Air sealing in San Angelo and the city's permit rules
The City of San Angelo requires an issued electrical permit for any electric work and an issued plumbing permit for any gas work, and an air sealing job can come close to both when we're working around wiring or a gas appliance. Whether sealing on its own needs a permit isn't something I'd guess at, so we check with the city's Building Permits & Inspections office on each job and take care of any permit it calls for, so you don't have to chase it. The city also lists the energy code and the existing-building code among the codes it has adopted, which is one more reason we ask before we start.
If AEP Texas is your electric utility, it lists home programs for residential customers that cover insulation and air leak work, including sealing attic accesses and plumbing openings, so it's worth checking what AEP Texas offers before you book. On jobs across San Angelo and the cities around it, the hatch and the plumbing openings are where we usually find the leaks, and older houses tend to have more of them.
Why San Angelo homeowners call J&M San Angelo Insulation Services for air sealing
I look at every attic myself
I come out to each San Angelo house, go up in the attic and write the estimate, and our own crew does the sealing. You hear what your house needs from the person who looked, and if it doesn't need sealing, I'll say so.
Doing this work since 2013
I learned insulation crawling through attics with my dad and started this business in 2013. New insulation laid over a leak or a hidden problem just covers it up, so we fix and seal first.

Frequently asked questions
How do I know my home needs air sealing?
Drafty rooms, rooms that run warmer or cooler than the rest of the house, high heating or cooling bills and dust showing up below the attic are the usual signs a house could use air sealing. They don't prove it, but they're a good reason to have the attic looked at, and that's where I start.
Is air sealing safe if I have a gas furnace or water heater?
Sealing can affect a gas or oil appliance that vents on its own, so it needs testing before and after the work. A tighter house can sometimes make that appliance back-draft, pushing its exhaust into the house instead of up the vent, which isn't safe. We get it tested for proper drafting on both ends of the job so you know where it stands.
Should I seal my attic before adding insulation in San Angelo?
Yes, the sealing gets done first. The gaps in the attic floor are easy to reach while the old insulation is thin and hard to find once a fresh layer is down, so we close them before anything new goes on.
How long does attic air sealing take?
ENERGY STAR guidance puts attic air sealing at about 1 to 2 days with a contractor and 1 to 3 days for a homeowner doing it alone, and it rates the job as a difficult one. A tight hatch or a lot of openings can push a job toward the long end, and I'll tell you what to plan for at the estimate.
How much does air sealing cost in San Angelo?
The price comes down to how many openings your attic has, how easy it is to get into and whether anything has to be fixed before we seal. Caulk and spray foam at the gaps usually costs less than foaming the attic, and adding insulation afterward adds to the total. I'll give you a figure for your house at the estimate.
What has to be fixed before an attic can be air sealed?
Wet insulation from a leaky roof, moldy or rotted framing and old knob and tube wiring, which can be a fire hazard when it touches insulation, should be corrected by a professional before sealing goes ahead. Kitchen, bath or dryer vents that dump moist air into the attic and an attic with little or no ventilation belong on that list too, so I check for all of them first.
Other work that often goes with air sealing
Basement insulation
Cold floors and a chilly lower level usually mean heat is getting away below the house, not just through the attic.
Closed-cell foam insulation
Dense foam that stops air and moisture in a single layer, worth the cost in spots where both need stopping.
