Existing Home Insulation

Insulation isn’t just for new homes. Many older homes have insulation that has settled, degraded, or never properly sealed-leading to drafts, uneven temperatures, and high energy bills.

At Sealtite Insulation & Slabjacking, we upgrade existing homes with high-performance insulation for attics, walls, basements, and crawl spaces—improving comfort, lowering energy costs, and enhancing indoor air quality.

Why It Matters

Proper insulation helps regulate temperature, reduce strain on your HVAC system, and prevent moisture issues like mold and wood rot.

Insulation Removal

Old or damaged insulation often needs to be removed before upgrading. Our team safely removes contaminated or ineffective materials, preparing your home for a clean, high-performance insulation system.

Frequently Asked Questions

How do I know if my home needs insulation upgrades?

Signs include high energy bills, uneven temperatures, drafts, and visible mold or moisture in walls or attics.

Can you insulate over existing insulation?

In some cases, yes. However, old insulation may need to be removed if it’s damaged, contaminated, or settled. Sealtite evaluates your home and recommends the best approach.

How long does insulation removal take?

Removal depends on the size of the space and type of existing insulation. Most homes usually take a day or less and our team works efficiently to minimize disruption while safely removing old material.

Is spray foam safe for existing homes?

Yes. Spray foam is applied by trained professionals and is safe once installed. It provides long-lasting energy savings and moisture protection. A healthy home is Sealtite’s priority, our staff will help you find answers on the health and safety of spray foam insulation in your home.

How soon will I notice a difference after insulating my home?

You can expect to notice more consistent temperatures, quieter rooms, and lower energy bills immediately after installation.

I have a room in my home that is always cold. Can you check to see if I have enough insulation in my walls?

Yes. We would need to drill small holes at the top of the wall or pull up siding and drill a hole to check for insulation. We could also check for sufficient insulation in the attic and basement/crawl space.

Customer Reviews

Kathy Armstrong

Our porch is warmer

“We had Sealtite put some insulation under our porch. It has made a difference keeping our porch warmer in the early spring and now in the summer. They were good about letting us know when they were able to do the job and did a good job!”

Colton Martin

Installers arrived promptly

“Sealtite recently completed a spray foam project which included the ceiling and walls of my metal pole building. The installers arrived promptly and were very courteous, they prepped the interior to eliminate overspray. I’m very satisfied with the quality of work performed by Sealtite and will reach out to them for any other services that I may need in the future.”

Brad Huette

Thorough and efficient

“Sealtite did a great job in our home remodel project. They were thorough and efficient. When they left the job site they did a fantastic job of leaving no trace that they had been there. Would recommend them for any insulation need you may have.”

Betty Finney

Very happy with service

“I’m very happy with the service provided. I have noticed a difference in HVAC efficiency as well as sound reduction. Would highly recommend.”

Meg Dickinson

Cleaned up well after the job

“The installation crew was profession and cleaned up well after putting up our foam insulation. We’ve noticed a huge difference in how comfortable and quiet our one-story addition is after being insulated. And as winter has set in, we’ve noticed our furnace is running less, which saves us money and makes our air quality better and less dry. We had a great experience with Sealtite and highly recommend the company!”
