What does insulating the whole house involve?
Home insulation in San Angelo means sealing the air leaks in your ceilings, walls and foundation, then adding insulation to the attic, floors, crawl space and rim joists, the boards that sit on the foundation, so your house costs less to heat and cool.
Most calls start with one room, usually the hot one upstairs or the room over the garage, but the cause is often spread across the house, so I'd rather look at all of it before I price any one piece. The price turns on the size of the house, how many inches are already up there, whether old material is soaked or full of droppings and has to come out, and how many gaps need sealing. The schedule turns on the same things, plus whether any electric work in the plan needs a city permit. If the attic is all you need, our attic insulation page covers that job, and either way the estimate gives you your own price and the order I'd do the work in.
How we handle home insulation from top to bottom
When you want the whole house done, I walk the attic, the walls and anything under the floor, then give you one plan in the order I'd tackle it, so you're not buying separate pieces that don't work together. On the job, anything wet or full of droppings comes out first, because fresh insulation laid over it just hides the problem. Then our crew seals the gaps around can lights, pipes, wires and the attic hatch, keeps a clear space around flues and chimneys, leaves the eave vents open so the attic can breathe, and fills to an even depth that runs all the way out to the edges, where most attics come up short.
If what's up there now is too far gone to cover, insulation removal comes before anything else. Cold floors usually trace back to what's under the house, and crawl space insulation fixes what attic work can't reach.
Seal and top up with blown-in
This suits most houses with an attic layer that's thin but still dry and clean, because sealing the gaps and topping up with blown-in, loose fill blown through a hose, gets you the most for your money. It's what I recommend most often.
Spray foam when the ducts live in the attic
When your ductwork runs through the attic, foam can be worth the extra cost because it seals air while it insulates. Open-cell foam blocks air very well but lets water vapor through, so where moisture is a concern I'll talk with you about closed-cell, the dense foam that blocks it.
Home insulation permits and houses in San Angelo
The city's Building Permits & Inspections office requires an issued electrical permit for any electric work, and its handouts name new construction, additions and renovations but don't mention insulation, so whether your job needs a permit is that office's call. I check with them on each job and take care of any permit they ask for, so you don't have to chase it. That matters most when the plan includes electric work, like swapping old can lights for IC-rated ones, the airtight kind that can be covered with insulation.
We're based in San Angelo and work in the cities around it, and we open a lot of older attics with a thin, packed-down layer, plenty of unsealed gaps and ductwork running right through them.
Why San Angelo homeowners call J&M San Angelo Insulation Services for home insulation
I come out to see your house
I look at each job in person and write the estimate myself, and our own crew does the install. You're talking to someone who has actually been in your attic, not reading off a sheet.
Straight answers since 2013
I learned this work crawling through attics with my dad and started the business in 2013. If your house doesn't need a job, I'll tell you, because I'd rather talk you out of work than sell you something that won't help.
Licensed and fully insured
We're licensed and fully insured, so you're not carrying the risk while our crew works in your attic or under your floor. That counts on a job where we're working around your wiring, ducts and flues.

Frequently asked questions
How much does attic insulation cost in San Angelo?
Attic insulation across the US usually costs about $1 to $3 per square foot, and that's a national range for attic work, not our price. Where your job lands turns on what's already up there, whether old material has to come out first and how many gaps need sealing. I'll give you your own number after I've been in your attic.
Should I seal air leaks before insulating my house?
Yes, seal first. The U.S. Energy Department's guidance is that money spent on insulation can be wasted when the holes and gaps in ceilings, walls and the foundation are left open, and its figure of up to 15% average savings on heating and cooling comes from insulating and sealing together. That's why air sealing, closing those gaps, comes before insulation in every plan I write.
Is blown-in or batt insulation better for my attic?
For most attics, blown-in is the better pick. The same national guidance says loose-fill fiberglass, rock wool or cellulose usually costs less than batts in an attic and covers better, though installation costs vary, so it isn't the cheaper choice every time. I'll tell you if your attic is one of the exceptions.
Where do I get a permit for insulation work in San Angelo?
Permits come from the city's Building Permits & Inspections office, on the first floor at 52 W. College Ave., phone 325-657-4210. For residential work, you fill out a building permit application and email it with drawings to the Permits Department. When we do the job, I make that check and handle any permit, so you won't need to call.
How long does the crew need to be in my attic, and do we have to leave?
Most families stay home during blown-in work, and how long we're up there turns on the attic's size, whether anything has to come out and how many gaps need sealing. Spray foam is different because it comes with a re-entry time, the wait before people and pets can come back inside, and you'll know that wait before we book.
How do I know if my house needs more insulation?
Rooms that run hot upstairs, cold floors and a bill that keeps climbing are the usual signs, and the next step is having someone look at what's already there. National guidance suggests having an insulation contractor check your current R-value, which is how well it slows heat, and recommend whether you need more and what type. I'll measure what you have and tell you straight if it's enough.
