Frequently Asked Questions
Best Insulation Type?
The best insulation for your home depends on your attic’s condition and energy goals. Most DFW homes see the best results with blown-in fiberglass, which is affordable, clean, and highly effective.
For maximum efficiency or problem attics, we may recommend spray foam or air sealing upgrades.
We’ll walk you through the options during your inspection and help you choose what works best for your home and budget.
Install Time?
Most insulation projects take 6–8 hours from start to finish.
Larger attics, insulation removal, or spray foam jobs may take longer, but we’ll give you a clear timeline before we begin.
Do You Remove Old Insulation?
Yes — we offer full insulation removal, including vacuuming out old, damaged, or contaminated insulation.
We remove debris, sanitize as needed, and prep the attic for a clean, proper insulation install.
Cleanup?
We treat your home with respect. Our team cleans the workspace and vacuums before leaving. No mess. No dust. No surprises.
Warranties?
All CoreLine insulations come with a workmanship warranty, plus manufacturer warranties on the materials we use.
If anything isn’t right, we make it right — no hassle.
