Question 1

Will spray foam make my house too “tight”?

Accepted Answer

A well-sealed home does need controlled ventilation, and that's part of what we talk through during your free assessment. Closed-cell foam stops the uncontrolled air leaks that cause drafts and hot/cold spots, without stopping your home from breathing the way it's designed to. If a ventilation upgrade should go along with the insulation, we'll tell you before we start, not after.

Question 2

Which is better, open-cell or closed-cell?

Accepted Answer

In Southern Idaho, we only install closed-cell foam. It has a higher R-value per inch, adds structural rigidity, and creates an air, vapor, and moisture barrier in one application, which matters given how much our winters and summers swing here. Open-cell has its place in some climates, but we don't offer it as a residential option in this region.

Question 3

Can spray foam be applied to existing walls?

Accepted Answer

Yes. On existing homes we can inject closed-cell foam into finished wall cavities through small access holes, then patch and finish those spots when we're done. It's a common retrofit for older homes in Burley, Twin Falls, and Pocatello that were originally insulated with fiberglass batts.

Question 4

How long does spray foam insulation last?

Accepted Answer

Closed-cell spray foam doesn't settle, sag, or lose R-value the way fiberglass batts can over time. Installed correctly, it's built to last the life of the building, which is part of why the upfront cost is higher than fiberglass. You're paying once instead of re-insulating down the road.

Question 5

Do you insulate older homes, or only new construction?

Accepted Answer

Both. A lot of our residential work is retrofitting older homes across Burley, Twin Falls, and Pocatello that were never insulated to today's standards, alongside new-construction jobs where we're brought in before drywall goes up.

Question 6

Will spray foam insulation lower my energy bills?

Accepted Answer

That's the goal. Sealing the air leaks that fiberglass insulation misses means your HVAC system doesn't have to work as hard to hold a temperature, which is where the savings come from. How much you save depends on your home's current insulation, size, and HVAC setup, something we can talk through during your free assessment.
