Edinburg's fast-growing north side runs two-story brick and stucco homes with bonus rooms, three-car garages, and hot west walls that face full sun for six hours a day. Your attic sits on a concrete slab foundation, and above it runs the air handler and ductwork carrying 150 to 160 degrees of conditioned air under some of the hottest sun in Texas.

When that attic is vented and your insulation is compressed, wet, or missing in patches, your cooling system runs all summer and your electric bill climbs. McAllen Spray Foam Insulation has been serving Edinburg and the Rio Grande Valley since 2012. We spray foam attics, seal air leaks around rim joists and garage band boards, inject foam into closed walls, and remove and replace insulation that has failed. Our team is fully insured, and we write every estimate with the R-value and thickness specs so you know exactly what you are getting.

Spray Foam Insulation in Edinburg (78539)

Edinburg homes built in the 1990s and later are tight construction, but attic insulation often settles, compacts, or gets disturbed during HVAC service. Your vented attic is the hottest part of your home. Ductwork runs through it uninsulated or poorly insulated, and every inch of exposed metal or fiberglass loses cool air to the 150-degree air around it. Humidity from the Gulf pushes inward through walls and attics year-round, and condensation can form on the underside of metal roof decks or on cold ductwork when the cooling system shuts down. Closed cell spray foam seals all of that. It sticks to wood, metal, and block. It cures hard and holds its R-value. Open cell foam is lighter, cheaper, and still stops air leaks, but it is vapor-permeable and better suited to dry climates or to walls where drying to the inside is the goal. For your hot attic and your ductwork, closed cell is usually the answer.

We have been insulating Edinburg homes and commercial buildings around McAllen for over a decade. We know the local building stock, the heat load, the humidity, and what works.

How a Job Works in Edinburg

Call us at (956) 540-5716 or tell us about your job online. We schedule a free on-site visit. We look at your attic, crawl space, or walls. We measure the area, note the existing insulation and any damage, check for moisture or active leaks, and talk through what you want to achieve. We leave with photos and dimensions.

Back at the shop, we write a detailed estimate. It names the R-value, the thickness of foam per pass, the square footage or board footage, whether we are using open cell or closed cell, and the total price. If old insulation has to come out first, we price that separately and haul it away. If there is moisture or a roof leak, we tell you straight: we fix that first or we walk away. Your Edinburg home may sit on a concrete slab, and your attic may be tight to access. We bring the right equipment and we know how to work in those spaces.

On job day, our crew sets up mechanical ventilation. We spray the foam in controlled passes, holding the manufacturer ratio and drum temperature. We stay until the foam has set, usually a few hours. You can re-enter the space in twenty-four to forty-eight hours. We clean up, haul away scrap, and walk the job with you so you see what was done.

Spray foam attic insulation in Edinburg typically runs from $1.50 per square foot for open cell foam to $1.20 per board foot for closed cell, depending on thickness and R-value. A 1,200-square-foot attic with existing insulation that stays in place might run $1,800 to $2,400 for a closed cell top-up to R-30 or R-38. If old insulation has to come out, add $950 to $2,000 depending on coverage and condition. Wall injection foam for a closed wall cavity runs around $2 per square foot. Crawl space foam starts at $2,500. Rim joist and band joist sealing starts at $650. A garage attic or bonus room starts at $1,200. The real cost drivers are the area to cover, the R-value and thickness you want, whether you choose open or closed cell, and what has to be removed first. We give you a firm price in writing after the on-site visit. Call us at (956) 540-5716 for a free estimate.

My bonus room over the garage never cools down, even with the AC running. What's happening?

That room is built over an unconditioned or poorly insulated garage. The attic above it gets to 160 degrees in summer, and the insulation between the garage and the bonus room is either thin, compressed, or missing in patches. Cool air from your ductwork leaks out through gaps and seams. Closed cell spray foam seals the attic above the garage, stops the air leaks, and holds its R-value under heat. It also sticks to the rim and band joists where the garage framing meets the house, which is another major leak point. Most bonus room jobs in Edinburg run $1,200 to $2,500 depending on the area and whether the existing insulation stays or comes out.

I found damp insulation in my attic and it smells musty. Can you just spray foam over it?

No. Wet or damp insulation has to come out before any foam goes in. Spray foam will not stick to a wet substrate, and trapping moisture under foam is how you get mold and rot. We remove the damp insulation, haul it away, let the framing dry, and then spray. If there is an active roof leak or gutter overflow, that gets fixed first or we walk away. Damp insulation removal in Edinburg usually runs $950 to $2,000 depending on coverage. Once the attic is dry, closed cell foam seals it and keeps it dry. Call (956) 540-5716 and describe what you are seeing. We will give you an honest assessment on site.

What does spray foam insulation cost for my Edinburg attic?

It depends on the size of the attic, the R-value you want, and whether you are using open cell or closed cell foam. Open cell runs from $0.55 per board foot. Closed cell runs from $1.20 per board foot. A typical 1,200-square-foot Edinburg attic with closed cell foam to R-38 runs roughly $1,800 to $2,400 if the existing insulation stays. If old insulation comes out first, add $950 to $2,000. The only way to get a real price is a free on-site estimate. We measure, we look at what you have, and we write it down with R-value and thickness. Call (956) 540-5716.

Does Edinburg require a permit for spray foam insulation, and who inspects the work?

Permitting and inspection rules are set by the City of Edinburg and by the building code in force at your address. Energy code, insulation R-value, ignition barriers, and thermal barriers are all governed locally. The building official at the City of Edinburg determines whether a permit is required and what the inspection looks like. We help you navigate what applies at your address, and we coordinate with the city. Check the City of Edinburg website or call the building department to confirm what your property requires before work begins. We will answer any questions the inspector has about thickness, R-value, and installation.

Can my family stay in the house while you spray foam the attic? Will it smell?

Yes, you can stay home. Spray foam has a chemical smell during application and cure. We run mechanical ventilation during the job and for several hours after to pull fumes out of the attic and out of the house. The smell fades as the foam cures. We tell you to keep windows open and to stay out of the attic for twenty-four to forty-eight hours. Bonus rooms and bedrooms below the attic can usually be used normally once ventilation is running. If you have a metal building or a garage attached to the house, we will coordinate the timing so occupied rooms are not affected. Ask us about your specific layout when you call (956) 540-5716.

Are you insured for spray foam work at my Edinburg home?

Yes. We are fully insured with general liability and workers' compensation coverage. Our crew is covered for the work they do on your property. When you get an estimate from any spray foam contractor, ask to see proof of insurance and verify the coverage with the insurance company. We will provide that information before we start work.

Summer is here and my electric bill is out of control. Is it too late to add insulation?

No, but summer is the busiest season in Edinburg because everyone is feeling the heat. Spray foam work can be done year-round, but the longer you wait, the longer your cooling system runs and the higher your bill climbs. If you call now, we can often schedule within a week or two. Fall and winter are slower, so scheduling is easier, but you will have already paid for a summer of poor cooling. If your attic insulation is compressed or missing, spray foam will pay for itself in a few years of lower bills. Call (956) 540-5716 to get on the schedule.
