Hot upstairs, drafty rooms or high power bills usually mean air leaks through the attic floor. We seal the gaps so your rooms hold their temperature.
Attic air sealing in Las Cruces closes the gaps in your attic floor around pipes, wires, flues, the hatch and the tops of walls. We use sealant, one-part spray foam or rigid blocking, so hot attic air and dust stop slipping into the rooms below.
Most people call us because the upstairs or the room over the garage stays hot, the power bill keeps climbing, or nobody has looked in the attic for years. Insulation slows heat but doesn't stop air, so if the gaps under it stay open, the insulation is fighting a draft. We're based in Las Cruces and work across the cities around it, including Chaparral, Anthony and Canutillo, TX.
The price mostly turns on how big your attic is, how easy it is to move around in, how many large openings we find, and whether old insulation has to be pulled back or hauled out first. The schedule turns on any repairs that come first, a permit check and testing gas appliances. I give you your own figure in writing after I've been up there.
Sealing is the easy part. First I look for anything that would make sealing a mistake, because those problems get fixed before our crew closes a single gap.
Damp insulation, moldy or rotted rafters or joists, vents that dump moist air into the attic, and an attic with little or no ventilation all need a professional fix before anyone seals. Sealing over them traps the problem, so if I find any of it, it goes on your estimate as the first stage of the job.
Vermiculite is a light, pea-size, flaky gray mineral that was poured into some older attics. If your attic has it, we leave it undisturbed until an approved lab tests it for asbestos, and the local health department can give you the name of one. We don't seal or insulate around it until you have that answer.
Knob and tube wiring is the old system of single wires strung on porcelain knobs, found in homes built before 1930. It can be a fire hazard when insulation touches it, so a professional should correct it before we work around it. If I see it, it goes on the plan as an early step.
Here are the four steps, in the order the work happens. I'm at your house for the estimate and again at the end, and our crew does the sealing in between.
Call (575) 222-9021 or send a request through our form, and tell us what's bothering you, whether it's a hot room, drafts or dust. We get back to you to set a time for the visit.
I come out myself, get into the attic and write down what I see, including anything that needs repair first. Your written estimate lays out each step in order, so you know what comes first and why.
Any repairs on the plan get done first, and we take care of any permit the job needs. Then our crew seals the big openings and works down to the smaller gaps around pipes, wires and the hatch.
Before we pack up, I go over the finished work myself, from the hatch out to the eaves. I show you what was sealed and what's on the plan next if you're adding insulation.
I look for the big openings first, at the tops of walls, around flues and over dropped ceilings, because that's where sealing does the most good. Chasing every pinhole while a gap behind a kneewall stays open wastes your money. Large holes and open soffits usually get solid blocking, hot flues get metal and a collar instead of foam, and some can lights get covers before anything goes over them.
Damp spots, old wiring and gas appliances that vent on their own get sorted out as part of the plan, so nothing turns up halfway through the job. When sealing is part of a bigger project to add insulation to an older house, it's the first stage of our retrofit insulation work, and your estimate shows it that way.
Foam costs more, and it seals air while it insulates. For most attics, sealing the gaps and topping up loose fill gets you more for the money. Ductwork is the exception. If your ducts run through the attic, spray foam insulation at the roofline brings them inside the sealed space, and I'll tell you at the estimate which way your house leans.
If the insulation already up there is dry, clean and deep enough, we pull it back at each gap, seal underneath and lay it back down. You pay for the sealing and not for material you don't need.
If the old layer is thin or patchy, we seal first and then add blown-in insulation, which is loose fill blown through a hose. We run it full depth out to the edges and keep the eave vents clear so the attic still breathes.
Send your request and we reply within one business day to set a time for me to come look at your attic. The estimate is free, done on site and comes with no obligation. Tell us which rooms run drafty or uneven and whether your home has gas or oil appliances, so I know where to look first.
(575) 222-9021The City of Las Cruces says most building projects need an application review before a permit is issued, and applications go through the city's Citizen Portal. That doesn't settle whether every attic sealing job needs one, so before work starts I check with the office that covers your address. If yours needs a permit, we apply for it, set up the inspections and keep you posted on where it stands.
The state's energy figures put Las Cruces ahead of Roswell for cooling, with drier air in the hottest hours. So most of the calls we get here are about heat, a hot upstairs or a room over the garage, and the leaks we chase are the ones pulling attic heat and dust down into the house. We do the same work in Chaparral and Anthony.
I learned this trade under an old-school boss who made me tear out and redo anything that wasn't right, and I started this business in 2023 after years on his crews. I'd rather tell you an attic isn't ready for sealing than seal it wrong, so your estimate says plainly what has to be fixed first.
I do the estimate visit myself. Our crew does the work, and I run each job and check it before we leave. New Mexico requires a license of anyone who offers contracting work and has its own license class for insulation, so ask whoever you hire about theirs. We're licensed and insured.
Our attic work is backed by our satisfaction guarantee. If nobody has been in your attic for years, that's the place to start, so call (575) 222-9021 or send us a request and I'll come see what's up there.
If your older house is short on insulation, retrofit work adds it without tearing into finished rooms, with the gaps sealed before anything goes in.
When ducts run through the attic or you want one layer that stops air and slows heat, foam at the roofline does both.
We seal attics in Las Cruces and in the cities nearby. The same checks and the same order of work apply wherever your house is.
It probably is if you have drafty rooms, rooms that run warmer or cooler than the rest, high heating or cooling bills, or dust showing up in the rooms under the attic. Any one of those is a good reason to have the attic looked at, and I'll tell you at the estimate whether sealing will help.
Yes. Every opening in the attic floor should be sealed before new insulation goes into an existing vented attic, because once the new layer is down, those gaps are buried and much harder to reach. If you're planning insulation, book the sealing as the first step of the same project.
Yes, when the appliances are tested. ENERGY STAR suggests checking gas and oil appliances for proper drafting before and after sealing, because a tighter house can sometimes make a naturally venting water heater or furnace back-draft exhaust into your home. We put that testing in the plan from the start.
There's no set price, because the figure comes from your attic. Sealing alone costs less than sealing plus a fresh layer of loose fill, and foam at the roofline costs more than either. Old insulation that's soaked or full of droppings adds removal before anything else. Your estimate gives you the figure for your attic.
On-site time depends on how many openings your attic has and how hard they are to reach, so I give you the timing at the estimate instead of guessing now. Repairs or a permit can push the start date. Whether you need to step out depends on the materials, and I'll tell you the re-entry time, when everyone can come back in, before work starts.
Clear a path to the attic hatch and move anything stored right under it, so the crew can get up without crossing the whole house. Keep pets in another room while we work, and tell us which rooms run hot or drafty so we know where to look.
Before you spend anything on new insulation, call (575) 222-9021, because one visit shows where the air gets in and what has to happen first.
