Can’t say enough about the fabulous job that core line did on my attic insulation. Guys came on time and immediately started working. Removed all of my old insulation, sanitized the attic and then replaced everything. Spent time cleaning up every area inside and outside my home. Highly recommend core line.

Professional, Efficient, and a Massive Difference in Home Comfort!
I recently hired CORELINE INSULATION to upgrade the energy efficiency of my home here in the DFW area, and I couldn't be more impressed.
From the initial consultation to the final cleanup, the entire process was seamless.
The team was incredibly knowledgeable and took the time to explain exactly where my home was losing energy.
They didn't just try to sell me a service; they provided a clear plan to help lower my electricity bills and make our rooms feel more consistent in temperature.
A few things that stood out: Professionalism: They arrived right on time and were very respectful of my home, using drop cloths and ensuring everything was spotless before they left.
Expertise: You can tell they know the Texas climate.
They recommended the perfect solution for our specific attic layout. Immediate Results: I noticed a difference in how little my A/C cycled on within 24 hours of the job being finished. If you’re looking for a reliable, local company that actually delivers on its promises of energy efficiency, I highly recommend CORELINE INSULATION.
It truly is an investment that pays for itself in comfort and savings!
Thanks again to CORELINE INSULATION FOR AN EXCELLENT JOB WELL DONE!

Serving
Who Do We Serve?
Whether you’re a homeowner looking to enhance comfort and energy efficiency or a builder seeking reliable insulation for a commercial development, our team is equipped to deliver expert service with lasting results.
Have questions about insulation, pricing, or the installation process? We’ve answered some of the most common questions homeowners ask before getting started.
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.
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.
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.
We treat your home with respect. Our team cleans the workspace and vacuums before leaving. No mess. No dust. No surprises.
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.
