Frequently Asked Questions

National guides list about $1.50 to $5.00 per square foot installed. HomeGuide puts a whole house at $8,000 to $20,000, and an attic roof deck at $1,500 to $9,000. We measure and send a written price.

Georgia's residential energy code, the 2015 IECC with Georgia amendments, lists R-13 for wood-frame walls in Climate Zones 2 through 4, which covers Macon. Ceilings are R-38. That applies to new construction and additions.

Foam does not feed mold, but if it covers a leak or wet wood, moisture can be trapped. That is why we fix leaks and dry out surfaces first, and why closed cell is used where moisture is a risk.

Many vented crawl spaces here get damp in summer. Sealing the vents, laying a heavy liner and drying the space often helps, but water entry and termite inspection access have to be handled first. Sometimes insulating the floor is the better choice.

For foam on the roof deck over attic ductwork, open cell is common and costs less. On the attic floor, sealing plus blown-in is usually the better value. Closed cell makes sense where space is tight or moisture is a concern.

Georgia Power's Home Energy Improvement Program lists rebates for attic insulation and air sealing, with rules on existing insulation levels and installer requirements. Check the program page for current amounts before you plan.

Where heat and humid air leaking in are the main problems, often yes, especially for attics with ductwork. On a simple attic floor, sealing plus blown-in usually gives similar comfort for less.

Not usually. Foam must bond to wood or concrete, so old batts in the way come out first.

It can if it hides areas your pest company needs to inspect. Talk to them before foam goes on foundation walls, and we will plan inspection access.

Installed correctly and kept dry, it lasts for the life of the framing it is attached to.

It can if inspection areas get covered. Check with your pest control company first. We leave inspection access and can work to their requirements.

Most sealed crawl spaces need some drying. We recommend a dehumidifier or conditioned air based on your house.

For some homes, yes. Closed-cell foam under the floor keeps the house comfortable even if the crawl space stays vented.

Most crawl spaces take one to three days.

Georgia's code lists R-38 for new homes. For existing attics, the Department of Energy suggests R-49 to R-60 if bare, or adding R-38 to R-49 over what is there.

It may. The program has rules about existing insulation, the R-value you reach and who does the air sealing. Check Georgia Power's page for current terms before you plan.

Thin insulation, ceiling air leaks and ducts in a hot attic are the usual causes.

Most sealing and blow-in jobs take a day. Roofline foam may take longer.

Not if it is clean and dry. We remove insulation that is wet, contaminated or in the way of sealing.

Most attic or crawl space jobs take one to two days with reinsulation.

It should be removed with protective equipment and containment, which is how we handle it.

Yes, slowly. Fixr lists about $1.50 to $3 per square foot, up to about $5 when chipped by hand.

Usually, through small holes that get plugged and patched. We check for fire blocking and old wiring first.

Brick veneer walls can often be filled from inside. We look at each house.

Yes, especially on walls that face the afternoon sun.

One to three days for most homes.

Both work. Cellulose resists air movement better, fiberglass handles moisture better. We suggest one and can price both.

Most attics are done in a day.

Slightly. We install to the settled depth for your target R-value.

Yes, if the old insulation is dry and clean.
