About San Angelo, TX

I grew up crawling through attics with my dad and started this business in San Angelo in 2013. The city is mostly single-story houses on wide lots, from the older blocks near downtown and the Concho River out to the newer subdivisions on its edges, with shops and metal buildings scattered among them and on the bigger lots around it.

Older houses here often still have whatever insulation went in when they were built, with ductwork running through the attic above it, and newer ones usually leak air around the hatch and the ceiling lights. Either way, most jobs here start in a low, hot attic, and the first thing I do is find out what's already up there.

Services in San Angelo, TX

  • Attic insulation

    Plenty of San Angelo attics are down to a few thin inches, and the rooms below are hot by mid-afternoon. We top them up with blown-in insulation, loose fill blown through a hose, and bring the edges up to the same depth as the middle, because the edges are where most attics come up short.

  • Attic air sealing

    Gaps around ceiling lights, pipes and the attic hatch let hot attic air straight into the house, and piling on more insulation doesn't stop a draft. We do the air sealing first, closing those gaps with foam and caulk, so the insulation on top isn't fighting moving air.

  • Spray foam insulation

    The room over the garage and any bonus room tucked under the roof tend to be the hottest in the house, because the sloped ceilings leave little space for insulation. Spray foam insulation fills those slopes completely, which loose fill can't do on a slant.

  • Insulation removal

    Some older attics here have insulation that's been wet or full of droppings, and laying fresh material over it just buries the problem. We bag the old stuff out and clean up, and only then does new insulation go in.

  • Crawl space insulation

    Older houses that sit over a crawl space give you cold floors every time a norther blows through. We insulate between the floor joists and seal around the pipes that come up through the floor, so the rooms above stay warmer.

  • Commercial insulation

    Metal shops and buildings around San Angelo turn into ovens in summer and drip condensation on cold mornings. We spray closed-cell foam, a dense foam that also blocks moisture, right onto the metal so the inside stays cooler and the dripping eases up.

What to know about permits and pricing in San Angelo

The city's Building Permits and Inspections division issues permits for building work here, and what it spells out is electric and gas work, not insulation. So I check with that office on every job and we take care of any permit it calls for, and if one is needed, the install waits until it's issued. The city also requires a long list of contractors to register, from general and building contractors to electricians, plumbers and roofers, so it's fair to ask anyone you hire where they stand. If your job turns up wiring that needs work, that goes to an electrical contractor, and the Texas Department of Licensing and Regulation requires each one to have a master electrician of record, either the owner or a licensed master on staff.

What moves the price here is mostly what I find in the attic: how many inches are already up there, how much has to come out first and how much sealing the house needs. The schedule turns on the same things, plus a permit if the city calls for one, and my estimate at your house is where you get your own number. I'd rather talk you out of a job than sell you one your house doesn't need. We're licensed and fully insured, and our own crew does every install.

San Angelo, TX properties and local conditions

Summer brings most of our calls. A San Angelo attic bakes for months, and when the insulation up there has settled to a few inches, the heat comes straight through the ceiling and the back bedrooms stay warm well into the night. We check the eave vents along the edges too, because insulation packed over them stops the attic from breathing and moisture starts showing in the framing, so we keep them clear when we add depth.

Winter is shorter, but it still finds the gaps. The residential code here plans homes for a winter low of 32 degrees, a design number rather than a weather record, and that's when older floors over a crawl space go cold and the heater runs hard. We insulate under those floors and seal where the pipes come through so the warm air stays inside.

How it works when you call us in San Angelo

  1. Call us or send the form

    Tell us what's going on, whether it's a hot room, a high power bill or a tired old attic, and we'll set a time for me to come out. Someone needs to be home to let me into the attic or crawl space.

  2. I check the attic myself

    I measure how many inches are already up there and look for wet or dirty material, open gaps and buried vents, then check the walls or crawl space if that's where the trouble is. Usually you'll have a clear answer before I leave, including the work I'd skip.

  3. Our crew preps, then installs

    Once you say go, our crew handles the prep and safety checks first, covering things below the hatch and clearing out any old material that has to go. Then they seal the gaps and put the insulation in, in that order.

  4. We walk the job together

    When the crew's done, I walk the finished attic or crawl space with you so you can see the depth and the sealed gaps for yourself. Our work comes with one promise, satisfaction guaranteed.

Frequently asked questions

Does moving wiring or a gas line in my attic need a permit in San Angelo?

Yes, the city says an electrical permit is still required for all electric work and an issued plumbing permit is still required for all gas work. We insulate and seal around the wiring, furnaces and water heaters we find in San Angelo attics, and if any of it needs fixing, that's a job for an electrician or plumber under its own permit.

Which building codes does San Angelo use for insulation work?

San Angelo builds to the 2021 International Residential Code and a 2021 energy conservation code, along with a few local changes the city has made. You can see the full current list on the city's codes and regulations page.

What makes insulation cost more on an older San Angelo house?

Old insulation that has to come out first usually adds the most, since it's a whole extra step before anything new goes in. A cramped attic and a lot of gaps to seal add to it too, and I'll point out which of these apply to your house while I'm up there.

How long does attic insulation take, and do we have to leave the house?

With blown-in insulation you can usually stay home, and topping up an attic is often a short job unless old material has to come out first. Spray foam is different, because everyone, kids and pets included, stays out until the re-entry time, the point when it's safe to come back, and I'll give you that time before we start so you can plan around it.

How do I tell if my San Angelo attic needs more insulation?

If you can look in from the hatch and see the tops of the ceiling joists, there usually isn't enough up there. Back rooms that won't cool down and a power bill that jumps every summer point the same way, and when I come out I measure what's there so you know for sure.

Is spray foam or blown-in insulation better for a San Angelo attic?

For most houses here, sealing the gaps and topping up with blown-in is the better buy, because foam costs more and the attic usually doesn't need it. The exception is when your ductwork runs through the attic, since foam on the underside of the roof seals air while it insulates and keeps those ducts out of the worst of the summer heat.
