Indiana Crawl Space Repair is a trusted crawl space repair contractor providing waterproofing, insulation, encapsulation, drainage, vapor barriers, and structural repairs in Indiana and the Greater Indianapolis area. Our Estimates are free, and most of the time can be scheduled the same day you contact us. Give us a call at 800-371-1939 to schedule an appointment

"First I would like to say that everyone I dealt with at ICSR was great! From Erika who made the appointments to Jeremiah who did the inspection, to Terry and his crew. They were all friendly, respectful, and knowledgeable. Jeremiah explained in detail what needed done in my crawlspace. There was a lot of damage due to termites in the past. I knew this was what needed done as I had another Company look at it as well. They backed out because they thought the crawlspace was to narrow to get the work done. I agreed to Jeremiah's plan and about two weeks later Larry and his crew came out to do the work. I will say it again, Larry and his crew were great. They worked so hard and in horrible heat and humidity. They were always friendly and smiled when I saw them. Larry always let me know what they got done that day, and what the plan was for the next. They cleaned up the work area, and took away any and all debris. I have full faith in ICSR and Larry and his crew that the repairs were done right. I am so glad the plan with the other company fell through, as I think I ended up with the best!"

Insulation questions, answered by experts

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.

As long as your existing insulation isn’t compromised, you can add new insulation directly over them. Inspect your insulation thoroughly and make any minor repairs. Then, add new insulation on top of it. You must be completely certain that there is no contamination or mold growth before doing so. That said, when unsure, consider removing old insulation and lay down fresh ones.

Just how long insulation lasts depends on the type of insulation you use. Fiberglass can last between 80 and 100 years, but it's important to start checking fiberglass insulation around the 15-year mark. Spray foam also has a long life span of up to 80 years, while mineral wool can last up to 100 years. Although eco-friendly, cellulose only has a lifespan of 20 to 30 years.

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road.
