Insulation Contractor in Mansfield, TX - Attics Sealed Before They're Filled

I climb into your attic, check the old insulation and find the gaps before quoting.
Request an estimateMansfield: an old downtown, newer subdivisions
Mansfield started at a gristmill where Main and Broad cross, and the downtown that grew there is still standing. Many of our calls here come from the subdivisions that filled in around it, where a lot of the houses are two stories with a bonus room over the garage. That's the room people tell us is hot upstairs in summer, drafty in winter and never quite matches the rest of the house, usually because the attic beside it and above it was insulated thin and left full of gaps.
We see the same mix next door in Burleson. In the older houses closer to downtown, the insulation up there is usually thin and settled and the gaps around pipes and wiring are bigger, so the sealing takes longer than the topping up.
How an insulation job runs in Mansfield
The city's Building Safety Department issues permits for construction, alterations and repairs to a house or its systems, so before we start I check with them about what your job needs. If it needs a permit, we pull it and set up the inspection on our end, and the start date waits on that, so I'll tell you at the estimate if it's likely. The city's inspections are covered by the permit fee, not billed on top. If you'd like to ask yourself, Building Safety takes calls at 817-276-4220.
Price moves with the size of the space, whether old insulation has to come out, and whether foam or blown-in fits, and the schedule moves with permits and anything that has to be fixed before we insulate, like a roof leak. I'll give you your own figure after I've been up in your attic, not over the phone. We work the same way in Grapevine and Arlington, but every house gets looked at on its own.
Services in Mansfield, TX
Attic insulation
Upstairs bedrooms in Mansfield's two-story houses run hot when the attic insulation is thin. We seal the gaps first, then fill evenly all the way out to the edges.
Attic air sealing
Drafty rooms usually trace back to gaps around can lights, pipes and the attic hatch. We close those gaps before any insulation goes down, so it isn't fighting a draft.
Closed-cell foam insulation
When ducts run through the attic or a crawl space stays damp, closed-cell foam, a dense foam that blocks moisture, seals and insulates together. We spray it once the wood underneath is dry.
Insulation removal
Older houses near downtown sometimes have insulation that got soaked or holds droppings, and new material over it keeps the problem. We bag the old material out and clean up first.
Crawl space insulation
Cold floors in older raised houses usually come from an open, damp crawl space underneath. We check for water and wet wood first, then insulate what's dry and sound.
Commercial insulation
Property managers and business owners in Mansfield call us about rooms that won't hold temperature. We walk the building, find the leaks, and insulate in the order that makes it work.

Frequently asked questions
How much does it cost to insulate an attic in Mansfield, TX?
Your price comes from your attic's size, how many inches are already up there and which material fits, so I give you a figure after I've seen it. Foam costs more and seals air while it insulates, but sealing the gaps and topping up blown-in insulation, loose fill blown through a hose, usually does the job for less unless your ductwork runs through the attic. Removing soaked or dirty insulation and working in a tight space, like a low attic over a garage, add to the cost.
Should I fix my roof before insulating my attic in Mansfield?
Yes, a roof leak should be fixed first, because insulation laid over wet wood holds the water and stops doing its job. In Mansfield, replacing only the shingles on a house needs no permit, but the city requires a re-roofing permit when decking or structural members like rafters or trusses are repaired or replaced. Once the roof is done and the wood is dry, we come in and insulate.
What building codes does Mansfield use for home construction?
Mansfield builds to the 2018 building codes with its own local changes, and the city's Building Safety Department is asking for public input on moving to the newer 2024 codes. Because that may change, we check with the city before each job about what your work needs.
Which contractors have to register with the City of Mansfield?
Electrical, mechanical and plumbing contractors, irrigators and third party energy contractors have to register with the city. On a remodel, each sub-contractor has to be registered and get its own permits, so if your job also means moving wiring or ductwork, that trade handles its own registration and permit. Building Safety, at the number above, can tell you what applies to your project.
What causes wet insulation under older homes in Mansfield?
Usually it's water getting in, from a roof leak, a plumbing drip or, under some older houses, flooding. The city notes that several homes were built before federal floodplain rules and will flood in a large enough storm. Wet insulation has to come out and the wood has to dry before we put anything new in, because fresh material over a wet problem keeps the problem.
How long do we have to stay out of the house after spray foam insulation?
That's set by the foam maker's re-entry time, the wait before people and pets can come back inside, and I'll tell you that number before we start. With blown-in insulation, most families usually stay home while we work. For foam, we plan the day so kids and pets are out before spraying begins.
