Drafty rooms, a hot upstairs and a power bill that keeps climbing usually trace back to gaps we can find and close.
Our air sealing services in Laredo, TX close the gaps where air slips in and out of your house. That means around door frames, ducts and fans, and where pipes, vents and wires pass through the walls, so the cooling you pay for stays in the rooms you use.
If the upstairs stays hot no matter where the thermostat sits, or the room over the garage never cools down, the air you're paying to cool is usually leaking into the attic while hot attic air comes in to replace it. The price turns on how big the house is, how much old insulation we have to move to reach the gaps, whether the ducts run through the attic and whether you want attic insulation added in the same visit. The schedule turns on what I find when I check the attic and whether anything has to be fixed before we seal. I write the estimate after I've been up there, so you'll see what's included before you decide.
I come out myself, get up into the attic and write your estimate, so the person pricing the job is the one who saw the gaps. I'm also on the install with our small crew, so nothing gets lost between the visit and the work.
I traded a desk for a ladder and learned insulation on another contractor's crew before we started our own business in 2023. That's 3 years of our own, mostly in attics, sealing, adding insulation and clearing out old material that's past saving.
We're licensed and fully insured, and the work is backed by our satisfaction guarantee. If the better move is to wait or bring in someone else first, I'll tell you before we seal anything. Call (956) 508-9070 to set up a visit.
We reply within one business day to set a time for me to come out, look at your attic and write up a free estimate at your property, with no pressure and no obligation. The estimate is written out so you can see what's included. If you know of a roof leak, a bath fan that vents into the attic or plans for new insulation, note it on the form so I can plan the visit.
Laredo's permit list names mechanical, plumbing and electrical work, each pulled by a contractor licensed in that trade, and it doesn't name air sealing, so the list alone doesn't settle whether your job needs a permit. Building Development Services at the city is the place to ask, and when a job does need a city permit, we pull it as your contractor and handle the paperwork. If the work touches your ducts, wiring or plumbing and someone else does that part, the city's building permit resources point you to the Texas Department of Licensing and Regulation to check A/C companies and electricians, and to the Texas State Board of Plumbing Examiners to check plumbers.
We're based in Laredo and work across Laredo and the cities around it. A lot of the houses we get into here have the air conditioning ducts running through the attic and years of insulation piled over the ceiling, so the leaks that matter most are usually the ones nobody has looked at in a long time. You can read more about our insulation work across Laredo.
Yes, for the obvious ones, like gaps around door frames and where pipes come through a wall, a basic do-it-yourself fix works fine. What it won't find are the small, hard to spot leaks, and in an older attic those usually sit under layers of insulation, which takes a closer search. That closer search is the part we're usually called for.
It can, so a good sealing job includes a plan for fresh air. In a tighter house without proper ventilation, water vapor and harmful gases can build up, and a gas appliance that can't get enough air may give off carbon monoxide. If anything in your house burns fuel, show me when I come out.
Yes, sealing comes before insulating because that's how you get the most energy savings, so book it first or as part of the same job. Once fresh insulation goes down, the gaps under it are buried again. The city's building permit resources also list a memo on ceiling insulation requirements for our climate zone, so if you're adding insulation after we seal, ask the city how it applies to your house.
We price each job after I've seen your attic, because the cost turns on how many gaps there are and how much old insulation sits on top of them. A bigger house, a cramped attic, ducts running through it or old material that has to come out first all add to it, and sealing only the obvious leaks costs less than a whole-attic job. Your estimate spells out what's included.
A hot upstairs, a drafty room or a power bill that's out of line with the size of the house usually points to air leaks. Home energy assessors find them with a blower door test, a fan that pulls air out of the house so the leaks show, and a thermal camera. One weatherization guide, written for another region, also describes measuring how tight the house is before and after the work, so you see a measured result.
Usually it's hot attic air pushing in through gaps in the ceiling below it while your cooled air leaks out the same way. Leaky ducts in the attic make it worse, and old cloth duct tape is a common culprit, because its glue dries out and lets go after enough hot and cold cycles. When we seal ducts, we use duct mastic, not cloth tape.
