Can you insulate the walls of a house that's already built?
Yes. Wall insulation in an existing San Angelo house usually means drilling small holes into each wall cavity and blowing insulation in, so your rooms hold their temperature without anyone tearing out drywall or siding.
You're probably here because one room is always hotter than the rest, the outside walls feel cold in January, or the power bill keeps climbing even after the attic got done. The price moves with how much wall we're filling, which side we work from, how deep the framing is and how much patching the drywall or siding needs afterward. The schedule depends on what I find before anyone drills, because an older house or old wiring can add a step, and on whether the city asks for a permit. When I come out, you get the number and the plan for your own walls.
How we handle wall insulation on an existing house
Before we touch a wall, I check the build year and the wiring, because either one can change the whole plan. Then I pick a side. For existing walls we usually drill and fill, which means boring a small hole near the top of each wall cavity and filling it with blown-in insulation, loose fill pushed through a hose until the space is packed. Going in from outside cuts through the weather layer behind your siding, if the house has one, and that layer then has to be patched or replaced. So I look at how easy each side is to reach and what shape that layer is in before I decide. When both sides are equally easy to get to, inside usually makes more sense because it leaves that layer alone. Once the cavities are full, we plug the holes and patch them.
Full walls still leak if the gaps around outlets, top plates and pipes stay open, so we often pair this work with air sealing services. If you have a finished lower level, basement insulation takes care of the below-grade walls that drill and fill doesn't reach.
Drill and fill from inside
This fits a house whose siding is in good shape or hard to get at, because the weather layer behind it never gets cut. The trade-off is a row of small patches on your interior walls that will need touch-up paint.
Drill and fill from outside
This suits you if you don't want your interior walls touched, or if the siding comes off and goes back on easily. The weather layer behind the siding has to be patched or replaced where we go through, so I only choose it when that layer can be put back right.
An outside layer with new siding
If you're already planning to re-side, that's the best time to add a continuous layer of insulation across the outside of the walls. Done then, it costs only a little more than the siding job by itself.
Planning wall insulation with the city in San Angelo
In San Angelo, permits for residential additions and renovations go through the city's Building Permits & Inspections office, and that office decides whether insulating your walls calls for one. We check with it on every job and take care of any permit it asks for, so you don't have to chase it.
A lot of the houses we work in have outside walls with little or nothing in them, and the complaint is nearly always the same. It's a west-facing bedroom or the room over the garage that never feels like the rest of the house. We see the same thing on jobs across San Angelo and the cities around it, so I look at those rooms first and tell you plainly whether the walls are the problem or the air is getting in somewhere else.

I come out to look at each job myself, and our own crew does the install. The person who sized up your walls is the same person answering for the work.

Straight answers about your walls
I'd rather talk you out of a job than sell you one your house doesn't need, and plenty of San Angelo calls end with me pointing at the attic instead of the walls. You'll know what your house needs and what it doesn't before you spend a dollar.

Frequently asked questions
How much does wall insulation cost in San Angelo?
Blown-in wall insulation across the US usually runs about $1.10 to $4.50 per square foot, and that's a national range for the material blown into the walls, not our price. Where your job lands depends on how much wall we fill, which side we work from and how much patching follows. The estimate gives you the actual number for your house.
Do we have to leave the house while you insulate the walls?
Usually not. When we blow from inside, we cover the floor below each wall and close off the work area so the dust stays put, which is what federal weatherization guidance calls for. I'll tell you at the estimate which rooms we'll be in.
What do I need to know about insulating walls in a house built before 1980?
Lead safety rules can apply, and how much they shape the job depends on how much of the wall gets disturbed, inside or out. A few small drill holes are a different plan from opening up big sections, so we sort that out before anything else.
Can you blow insulation into walls with knob and tube wiring?
Not around the wiring itself. The national electrical code bars insulation applied to or around knob and tube wiring, so in a house that has it, insulation stays off and away from those runs. If I find it, we'll talk through what that means for those walls before we plan anything.
How long does exterior wall insulation take to pay for itself?
Energy savings from a continuous outside layer often pay back in about 5 to 10 years. The comfort and the quieter rooms show up right away. The math works out best when you're replacing the siding anyway.
How do I know how much insulation my walls can hold?
It comes down to the framing. A 2x6 wall has a deeper cavity than a 2x4 wall, so it holds more insulation and slows more heat. If you don't know which you have, I'll find out at the visit.
