Cold floors over the crawl space or a power bill that keeps climbing? We seal and insulate it so the floor stays comfortable.
Crawl space insulation in Las Cruces seals the air leaks and insulates the crawl space walls, or in some homes the floor above it, so the floor over that space stops losing heat and feeling cold underfoot.
At Prime Las Cruces Spray Foam Insulation, most crawl space calls start with cold floors in one part of the house, a drafty room or a power bill that won't come down. Often nobody has been under the house in years, so I go down there and write down what I find before I talk about insulation at all.
The price moves with the size of the crawl space, how much room there is to work, what has to come out or get fixed first, and which material goes on the walls. The schedule turns on those same repairs, the check on any fuel-burning appliances and whether the job needs a permit. My written estimate lays out each step in order, so you can see what you're paying for.
A crawl space job goes right or wrong on a few things you can't see from the hallway. These are the ones I check and talk through with you at the estimate visit.
Fresh insulation laid over old batts that got soaked, or that are sagging off the floor framing, leaves the problem right where it was. If what's down there is wet or falling, we pull it out and find out why it got wet before anything new goes in.
One home guide says fiberglass isn't a good fit for most crawl spaces, vented ones especially, because it soaks up moisture and can lead to mold and insulation that works less well. It can suit a closed crawl space where moisture is well managed, which is why the drying plan comes before the material choice.
Some foam insulation can give off toxic or flammable gases if it gets hot, so most codes call for a covering such as drywall over it. Some foam products are made and tested to lower that risk, and local building officials decide whether a given foam meets code, so we settle that before we order material.
Here's how a crawl space job runs from the first call to the last look, and who handles each part. I'm the one on site for the estimate and the final check.
Call (575) 222-9021 or use our form and tell us which floors or rooms bother you. If you can, note the crawl space's rough square footage and any fuel-burning appliances in the house.
I come out myself, get into the crawl space and write down what I see, including anything that needs repair before insulation goes in. You get a written estimate that lays out each step in order.
We take care of any permit the job needs, and the repairs and the appliance check come before we seal anything. Then our crew seals the gaps, insulates and sets up the plan that keeps the space dry, and I run the job.
I go over the finished work before we pack up. After that, look in the crawl space about once a year for moisture getting in, and check that the insulation hasn't been damaged or shifted.
We usually lean toward insulating the crawl space walls instead of the floor above. Sealing and insulating the walls is considered good practice in every climate, because it ties the crawl space to the rest of the house. Before insulation goes up, we close the gaps where air gets through, the same kind of air sealing services we do elsewhere in the house, so the insulation isn't fighting a draft.
Once the crawl space is closed in, it still needs a way to dry out. One of the most effective is a small supply of conditioned air from your heating and cooling system, so the space stays tempered like the rest of the house. We plan that air supply into the job from the start. If rooms above need more help, wall insulation follows the same order of work.
Fuel-burning appliances get checked first. Sealing a crawl space can, in some cases, make a furnace or water heater that vents naturally pull its exhaust back into the house. So before we seal anything, those appliances get looked at. If the check turns up a problem, I'll tell you plainly that the job isn't ready yet and what has to happen first.
The walls get sealed and insulated, and the crawl space becomes part of the house, with a planned air supply to keep it dry. It's the approach we usually recommend, because it holds up in any climate.
Insulation goes up in the floor framing and the crawl space stays outside the house. It fits some homes, but the floor has to be sealed well, and moisture makes the material choice matter more.
We reply within one business day to set up a time. I come out myself, look over the crawl space and write each step down, and there's no obligation to go ahead.
(575) 222-9021The City of Las Cruces reviews most building projects before it issues a permit, and applications go through its Citizen Portal. That review checks a project against the city's codes and standards. Before work starts, I check with the office that covers your address. If your job needs a permit, we apply for it, set up the inspections and keep you posted on where it stands.
The state energy code puts Las Cruces, in Doña Ana County, in climate zone 3B, and since the walls approach holds up in every climate, it's our starting point here too. We do the same work in Chaparral and Anthony. Most crawl spaces we open around here haven't been looked at in years, and the old insulation is often hanging loose from the floor.
I learned this trade under an old-school boss who made me tear out and redo anything that wasn't right. After years on his crews, I started this business in 2023. I still work the way he taught me, in order, because insulation over a leak, bad wiring or gaps nobody sealed is money thrown away.
I do the estimate visit myself, and I run each job, so the person who looked at your crawl space is the one watching the work. Our crew does the installing, and I check it before we leave. We're licensed and insured, and our work is backed by our satisfaction guarantee. Call (575) 222-9021 or send us a request and I'll come take a look.
If a room still runs hot or cold once the floor is warm, the walls are often the next place heat slips through.
Drafts around outlets, windows and attic gaps can undo good insulation, so sealing the rest of the house is worth a look.
We're based in Las Cruces, NM and do crawl space work across the cities around it, including Chaparral, NM, Anthony, NM and Canutillo, TX. If your city isn't listed, call and ask.
Usually not, if the crawl space is closed and the walls have rigid foam board on them. In that setup the wall foam does the insulating, so the floor above doesn't need its own layer and the work stays on the walls. Floor insulation is still right for some homes, and I'll tell you which yours is after I've seen it.
Across the US, insulating a crawl space usually runs about $3 to $6 per square foot. That's the general market range, not our price. Your written estimate gives the figure for your crawl space, with each step listed so you can see what it covers.
A contractor licensed by New Mexico's Construction Industries Division, which requires a license for anyone doing or offering construction contracting. The division has a license classification for insulation work, covering installing insulating material in or on buildings. Ask any contractor you're considering which license they hold before you sign anything.
Usually not with foam board, but spray foam is different. The foam maker sets a re-entry time, how long before people and pets can come back inside, and we follow it. I'll tell you at the estimate which material your job uses, so you know ahead of time whether to plan a day away.
The schedule is set by what has to be fixed first and whether a permit is needed, so I lay out the order on your estimate. To get ready, clear the way to the crawl space opening and list any fuel-burning appliances, such as a gas furnace or water heater.
We answer (575) 222-9021 from 7 AM to 10 PM every day, so you can call after work or use the form whenever it suits you.
