Wall insulation
sealed for the Valley.

Walls are a major heat path in RGV homes. We insulate open framing with spray foam, inject foam into existing closed walls, and seal exterior walls — cutting heat gain and outside noise.

The walls matter too.

Attics get the attention, but walls are a major path for heat and humidity into a Rio Grande Valley home — especially west- and south-facing walls that take the full afternoon sun. Premium Foam insulates walls for both new construction and existing homes.

For new framing or major renovations, we spray open- or closed-cell foam directly into the open cavities — a complete air seal and the highest R-value per inch available. For finished homes, we inject foam into existing closed walls through small, patched access points, no demolition required.

We'll tell you honestly which approach fits your home and budget — including when batt insulation is the more sensible choice.

New build & retrofit.

Open framing, closed walls, and exterior — we cover all three.

Built for RGV walls.

Afternoon sun load. West- and south-facing RGV walls absorb hours of direct sun. Foam in those walls cuts the heat that drives your AC late into the evening.

Retrofit without demo. Injection foam lets us insulate existing finished walls through small access points — no tearing out drywall — so older homes get modern performance.

Air sealing + quiet. Spray foam seals the air leaks batt insulation can't, and open-cell foam noticeably dampens outside noise in interior and party walls.

Four steps.

1 · Free assessment. We evaluate your walls — open framing or finished — and recommend spray, injection, or batt.

2 · Scope & estimate. Foam type and access plan scoped with an itemized written estimate.

3 · Install. Spray into open cavities or inject into closed walls; access points patched clean.

4 · Walkthrough & warranty. We confirm coverage and deliver warranty paperwork.

Wall questions.

Can you insulate existing walls without tearing out drywall?
Yes — injection foam is designed for exactly that. We drill small access points, inject foam into the closed wall cavities, and patch the holes. No demolition, and your finished home gets modern wall insulation.
How much does wall insulation cost in the RGV?
It depends on whether walls are open or closed and the foam type. New-construction wall foam is typically priced with the overall foam package; injection foam for an existing home commonly runs $2,500–$7,000 depending on square footage. A free assessment gives an exact number.
Spray foam or batt for my walls?
Spray foam air-seals and delivers more R-value per inch — best for the Valley climate. Batt is more affordable and fine in some new-construction budgets. We'll give you an honest recommendation for your home.
Does wall foam help with noise?
Yes. Open-cell foam in interior and exterior walls noticeably reduces sound transfer — a common reason RGV homeowners add it to bedrooms and media rooms.
How long does wall insulation take?
New-construction wall foam is done with the broader foam scope; injection retrofits are usually completed in 1–2 days depending on home size.

Will new wall insulation lower my electric bill?
Yes, especially on sun-exposed walls. Combined with attic foam, sealed walls meaningfully cut cooling costs in the RGV's long summers.

Yes. CCL Contracting is licensed in Texas with general liability and workers' comp on every job. Premium Foam operates under CCL's licensing.
