Retrofit insulation in Fort Worth, TX adds insulation to a house that's already built, mostly in the attic, floors and crawl space, and seals the air leaks around it so your rooms hold their temperature. Apex Fort Worth Spray Foam Insulation is based in Fort Worth and does this work in many of the cities around it.
Most people call because the upstairs runs hot, the room over the garage never gets comfortable, or the power bill keeps climbing in a house that already has some insulation. The price mostly turns on how much is already up there, whether old material that's soaked or full of droppings needs insulation removal first, how many gaps need sealing and whether foam or loose fill fits your house. The schedule usually depends on anything that has to be fixed first, like a roof leak or old wiring, because we don't insulate over a problem. I come out, look at your house and give you the estimate myself, so you get a number for your house and not a guess.
How we handle retrofit insulation
A retrofit starts with a checkup of your house as it is, because that tells us where your money does the most good. I go up in the attic, measure how many inches are already there, look for old insulation that's been soaked or full of droppings, and find the gaps around can lights, pipes and the hatch. If something has to come first, like a roof leak, I'll tell you that before we sell you anything. Then our crew does the air sealing, closing those gaps before any insulation goes in, so the new layer isn't fighting a draft. We keep the eave vents clear so the attic can still breathe, blow in loose fill evenly all the way to the edges where it's usually thinnest, and clean up before we leave.
Some houses need a different approach. Spray foam insulation costs more but seals air while it insulates, so it's usually the better pick when your ductwork runs through the attic. If foam is the right call, I'll tell you at the estimate when you'll need to step out and when you can come back. For most houses, though, sealing the gaps and topping up through our attic insulation work does more for the money.
What shapes a retrofit insulation job in Fort Worth
The city builds by the national energy code with its own local changes to the energy code, so before we install anything, we check with the city's building office about what your job needs to meet, including how much insulation goes in and the fire and combustion safety rules.
Most of what we find here comes back to summer heat. A lot of houses around Fort Worth have their air conditioning ducts running through the attic, and when the insulation up there is thin or packed down, it shows up as a hot second floor and a garage room nobody wants to use. In older neighborhoods we often find old fill that has settled over the years, with gaps around lights and pipes that nobody sealed. We see the same thing on jobs in Haltom City and Burleson, and we handle it the same way.

Frequently asked questions
How much does it cost to add attic insulation in Fort Worth?
The closest figure we have is from nearby Dallas, where installing attic insulation usually costs about $1,800 to $2,500 per job. That's the going rate in that market, not our price, and your house can land above or below it depending on how much is already up there, whether old material has to come out and how much sealing it needs. I'll give you your own number once I've seen the attic.
Why should I seal air leaks before adding insulation?
Money spent on insulation can be wasted if the holes and gaps in your ceilings, walls and foundation aren't sealed first. Insulation slows heat, but it doesn't stop air pouring past a can light or around the attic hatch. That's why we plan the sealing as the first step of the same job.
What has to be fixed before insulating an attic?
Guidance for this work says active knob and tube wiring, the old kind strung on porcelain knobs, has to be replaced first, roof leaks have to be repaired, and bathroom fans that vent into the attic have to be vented outside. If a fan has been blowing into the attic, it's worth checking for mold near where it lets out. Some of these fixes need an electrician or a roofer, and I'll tell you that plainly instead of covering the problem up.
How do I insulate existing walls in an older Fort Worth house without tearing them open?
The common way is drill and fill, which makes small holes near the top of each wall cavity, from inside or outside, and fills the cavity with blown-in insulation, loose fill blown through a hose. If you're planning new siding, that's an ideal time to insulate the walls from the outside, so ask about it before the siding goes on. In houses built before 1980, wall work can bring lead safety rules into play depending on how much wall gets disturbed, so ask any crew how they follow them.
How do I deal with vermiculite insulation in my attic?
Have it tested before anyone works in the attic, because vermiculite may contain asbestos. Get professional advice on it, and the state health department is where guidance points homeowners. We leave it alone until you know what it is.
Is a radiant barrier worth it in a Fort Worth attic?
It often is, since a radiant barrier, a reflective sheet that turns back heat coming off the roof, is especially useful in hot, sunny climates where it helps keep the house cooler. It works alongside sealing and insulation rather than in place of them, so we talk about it once those are planned.
