Spray foam insulation
Spray foam fills and seals in one pass, which helps most when ducts run through a hot attic or the room over the garage won't cool. It costs more, so I tell you when it's worth it.

Hot rooms and old attics across Las Cruces
Most calls we get here start the same way. A bedroom is hot upstairs, the room over the garage won't cool down, or the power bill keeps climbing. Often nobody has looked in the attic for years. So the first thing I do is climb up and see how many inches are already there and how old the house is, because that tells me what the job really is.
What I find sets the order of the work. If the old insulation got wet or is full of droppings, it comes out first, since new material on top just buries the problem. Open gaps around can lights, pipes and the attic hatch get closed before anything else goes down. We do the same work for homeowners in Anthony and the other cities nearby.

Insulation services for Las Cruces homes and buildings
Attic insulation
For a hot upstairs or a climbing cooling bill, the attic is usually where we start. We check what's already there, seal the gaps, then make sure coverage is full at the edges as well as the middle.
Blown-in insulation
Blown-in insulation is loose fill blown through a hose, and it's the usual way to top up an attic that has settled thin over the years. We keep it clear of the eave vents.
Home insulation
When several rooms feel off at once, we look at the whole house, from the attic to the walls to the crawl space, and write out which part to fix first so your money goes where it counts.
Insulation removal
Old insulation that got wet, smells or is full of droppings has to come out before anything new goes in. We bag it, clean out the attic and look at the framing underneath.
Crawl space insulation
Cold floors in winter often trace back to an open crawl space. We check for water and loose ductwork first, then insulate so the floor above stays comfortable.
Wall insulation
Some older houses have little or nothing in the walls, and you feel it on the sunny side of the house. We look at how the walls are built before deciding how to fill them.
Air sealing services
Air sealing means closing the gaps where air leaks in and out before insulation goes on. It's often the best-value fix for a drafty house, and insulation works better once the drafts stop.
Basement insulation
Where a house or building has a basement, we insulate the walls and the rim joist, the band of framing on top of the foundation, once we've checked that no water is getting in.
Closed-cell foam insulation
Closed-cell foam is a dense foam that also blocks moisture. We use it where condensation or damp is a worry, like metal buildings, crawl spaces and rim joists, because it seals tight in a thin layer.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it fills odd-shaped roof lines and wall cavities well. It suits attics where ducts need shielding from the heat and moisture isn't the main concern.
Commercial insulation
We insulate shops, offices and metal buildings around Las Cruces. We look at how the space is used and what runs inside it before choosing foam or another material.
Crawl space vapor barrier
A crawl space vapor barrier is a heavy plastic sheet laid over the dirt to keep ground moisture out of the house. We deal with any standing water first, so nothing gets trapped underneath.
Vapor barrier installation
Some walls, ceilings and floors need a layer that keeps moisture out of the insulation. We put it on the side the building needs, which depends on how the wall or roof is built.
Attic air sealing
Before an attic gets new insulation, we seal around can lights, pipes, wires and the hatch. Skip that step and the insulation spends its life fighting a draft.
Retrofit insulation
Retrofit work adds insulation to a finished house without tearing it apart. We find out what's already in the attic and walls, then add where it's thin instead of starting over.

(575) 222-9021Permits, licenses and pricing for Las Cruces jobs
The City of Las Cruces issues building permits for most building projects, and applications go through the city's Citizen Portal once the address has been assigned by the city. The city reviews each application, so if your job needs a permit, that review sets the earliest start. You can check two things about any contractor here, the state contractor license and the city business license, which is also handled through that portal.
Here's what we do about it. Before work starts, I check with the office that covers your address. If the job needs a permit, we apply for it, set up the inspections and keep you posted on where it stands. I make that same check on every job, whether the house is in Las Cruces, Chaparral or Canutillo, TX.
The price moves with how much area we're covering, what's already up there and whether anything has to be fixed or removed before new insulation goes in. The schedule turns on the permit, if there is one, and on those fixes. Your written estimate lays out each step in the order we'll do it.
How we work, from the estimate to the final check
I learned this trade under an old-school boss who made me tear out and redo anything that wasn't right. I started this business in 2023 after years on his crews, and I still work the way he taught me. Insulation over a leak, bad wiring or gaps nobody sealed is money thrown away, so I'd rather tell you a job isn't ready yet than do it wrong.
I do the estimate visit myself, and I look hard at the attic, walls or crawl space before I quote. If something has to be fixed first, I say so plainly. Our crew does the work, and I run each job and check it before we leave. We're licensed and insured, and the work is backed by our satisfaction guarantee.
If your house has a hot room, a high bill or an attic nobody has checked in years, that's the visit to start with. Call (575) 222-9021 or send the estimate request form, and I'll come look before anyone quotes you a number.
What Las Cruces houses ask of insulation
Homes here fight heat more than cold, so most of our work is about keeping the attic's heat out of the living space. These are the things we look at on nearly every job.
Attic heat and the rooms below
In summer the attic gets far hotter than the rooms under it, and that heat comes down wherever the insulation is thin. That's why one bedroom runs hot while the rest of the house is fine. We check depth across the whole attic, because coverage is often deep in the middle and thin at the edges, which is backward.
Ductwork in the attic
Plenty of houses run their air conditioning ducts through the attic, right in the hottest part of the house. When that's the case, spray foam can make sense because it seals and insulates the space the ducts sit in. When the ducts live somewhere else, sealing the gaps and topping up loose fill usually wins, since it costs less and does the job.
Eave vents that need to breathe
Most attics are vented at the eaves, and a careless top-up buries those vents. Once that happens the attic stops breathing, and moisture can start showing up in the framing. We keep a clear path at each vent before we blow in new material, so the attic keeps moving air the way it was built to.
Shops and metal buildings
Metal buildings heat up fast under the desert sun, and bare metal can sweat when the air inside is cooler than the panels. Closed-cell foam handles both because it insulates and keeps moist air off the metal. For shops and offices, we start by asking how the space is used and what runs inside it, since that decides what goes on the walls and roof.
Questions Las Cruces homeowners ask about insulation
How much does attic insulation cost in Las Cruces?
Your price comes from a free written estimate after I see the attic, because the attic's size, how easy it is to reach and how many inches are already there set most of it. Removing old material adds to the job, and spray foam costs more than sealing gaps and topping up loose fill. The estimate lists each step so you can compare.
How long will the insulation crew be in my attic?
It comes down to what has to happen before new insulation goes in. An attic that only needs sealing and a top-up goes faster than one that needs old, dirty insulation pulled out first, and a permit review can come ahead of all of it. I walk you through the plan for your house at the estimate.
What do I need to do before an insulation crew comes to my house?
Clear a path to the attic hatch or crawl space door and move anything stored right under it. If you keep boxes in the attic, mention it at the estimate, because they may need to come down so we can reach the edges. We cover the floors along our path and clean up when we finish.
Do we have to leave the house while you spray foam?
Usually yes, for a while. The foam maker sets the re-entry time, which is how long before people and pets can come back inside, and we give you that time before we start so you can plan for the kids and pets. With blown-in loose fill, most families stay home while we work.
Does an insulation contractor need a license in New Mexico?
Yes. The state's Construction Industries Division says anyone doing construction-related contracting in New Mexico must be licensed, and every applicant has to give the division a $10,000 bond from a surety company to get and renew that license. Contracting without one is against the law, and the division can stop an unlicensed contractor's project.
Is a pre-submittal meeting required for a commercial insulation project in Las Cruces?
Only for larger projects. The city requires one before a permit application for commercial new construction, additions or alterations valued at $1 million or more, and for multi-family buildings of any value, starting with duplexes. Below $1 million the meeting is optional. If your shop or office work is part of a project that size, we plan around that meeting.
What flood help does the City of Las Cruces offer homeowners?
The city offers site visits and recommendations on retrofitting, drainage, floodproofing, elevation and other ways to cut flood risk, and its floodplain managers answer questions on maps, building code, basic insurance and financial help. Its stormwater and flood page is where to start. If your crawl space takes water, sort that out before we insulate it, because insulation over a wet floor holds the problem in.
