I check the wall type, the siding and any built-ins so the quote fits your house.
Request an estimateCan you insulate the walls of a house that's already built?
Yes. Wall insulation in San Luis fills the hollow spaces inside your existing walls through small drilled holes, so heat and outside air have a harder time getting through and the rooms along those walls stay steadier.
Most wall calls start with one room that never feels right, like the room over the garage, often after the attic insulation is done and it still runs hot. Filling the walls only helps if they're actually hollow, so that's the first thing I check, because I'd rather tell you your walls are fine than drill them for nothing. The price comes down to how many square feet of wall we're filling, whether it's block or frame, and how much siding or trim has to come off to reach the spaces. The schedule turns on those same things plus whether the city wants a permit. At the estimate I look at your walls in person and go over what they need before I write it up.
How we do wall insulation, in order
Before anybody drills, we find any wall spaces that work as heating or cooling ducts and mark them, because those have to stay empty. We cover the shrubs and plants along the outside, and inside we catch the drilling dust at the bit instead of sweeping it up later. Then we drill so every space gets its own hole, including the closed-off ones behind built-in shelves or cabinets. Block walls get foam in the hollow cores. Frame walls get blown-in fill, loose material blown through a hose, packed full so it holds its place and doesn't slump. Last, we plug the holes, put back any siding that came off and clean up.
Filled walls still leak air around outlets, pipes and the spots where walls meet the attic, so we often pair this job with air sealing, which closes those gaps first. If part of your house sits below ground, basement insulation is its own job, and I'll tell you at the estimate whether it's worth doing.
Wall insulation permits and houses in San Luis
Whether a wall insulation job in San Luis needs a permit isn't something I'll guess on. The City of San Luis Development Services Department handles permits and inspections for projects in the city, and its Building Safety division inspects construction for compliance with local, state and federal construction laws. We check with that office before any work starts, and if you'd like to ask them yourself, Building Safety's number is 928-341-8565.
Around San Luis we work on concrete block houses and wood-frame houses, and sometimes both under one roof when an addition went up later, so I check each wall instead of assuming the whole house is built the same. We see that same mix on jobs in Somerton and Yuma.

Frequently asked questions
Can my block walls in San Luis be insulated?
Yes. Foam can go into the hollow cores of a concrete block wall after it's built, either through small drilled holes or from the top of the wall. The cellulose makers' own trade group recommends against using cellulose to fill masonry walls, which is why block is foam work for us.
How do I know my walls are completely filled with insulation?
A wall is filled right when every space got reached and the fill went in dense enough that it won't settle. Settling or a rushed fill leaves empty pockets, usually up high where you'll never see them, so the care the crew takes decides how well the wall is covered. Our wall work is backed by our satisfaction guarantee.
Is re-siding a good time to add wall insulation?
Yes, for a wood-frame house it's the best time to add continuous insulation, an unbroken layer on the outside of the wall. National energy guidance says that added while the siding's off anyway, it costs only a little more than the siding job and often pays back in energy savings in 5 to 10 years. The comfort and quieter rooms show up right away, so tell me about siding plans before they're set.
How much does wall insulation cost in San Luis, AZ?
Across the US, installing blown-in wall insulation usually runs about $4 to $4.50 per square foot. That's a national number for blown-in fill, so treat it as a rough guide and not a San Luis quote or ours. Your own figure comes from the estimate, once I've seen your walls.
How do I insulate walls without tearing out the drywall?
You fill them through small holes drilled into each wall space, from inside or outside, and then plug the holes. Working from outside means taking siding off where needed, and vinyl, aluminum and steel siding can often be loosened with a siding tool and put back, so your siding type shapes how much outside work the job takes.
Can you insulate interior walls in an existing house?
Yes, interior walls can be filled the same way, usually to quiet things down between rooms. Weak spots that might not hold up to the filling pressure get reinforced first or filled at lower pressure, so the wall doesn't bulge or crack.
Other work that goes with wall insulation
Air sealing services
Gaps around outlets, pipes and attic openings let air slip past even a full wall, and sealing them first keeps your new insulation doing its job.
Basement insulation
Below-grade walls deal with ground contact and moisture that a hollow frame wall never sees, so they need their own plan before any insulation goes up.
