Expert Spray Foam Insulation Services in Plano, TX
Complete home insulation solutions for Plano homeowners — attics, walls, crawlspaces, and floors. CoreLine Insulation assesses your whole-home thermal envelope and recommends the right insulation type and R-value for every area. Our team operates out of 2321 Choctaw Dr, Plano — your neighbors, not a national franchise.
Whether you’re upgrading an older Plano home that’s never had a proper energy assessment, adding insulation before a major renovation, or replacing damaged insulation after a roof or water event — CoreLine handles the full scope. We work with spray foam, blown-in, batt, and roll insulation and match each product to the right application.
Plano’s climate is demanding: summers exceed 100°F for weeks at a time, and winters can bring freezing temperatures that stress poorly insulated homes in the opposite direction. Proper residential insulation addresses both extremes — reducing HVAC load, improving comfort, and lowering monthly energy bills by 10–30% in most homes. Every project starts with a free inspection.

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!

FAQ
Frequently Asked Questions About Residential Insulation in Plano
How much does residential insulation cost in Plano, TX? +
Every residential insulation project is different — cost depends on insulation type, square footage, and whether old insulation needs to be removed first, which adds to project cost on retrofit jobs. Give us a call and we’ll come out to provide a tailored, no-obligation estimate. Our minimum project cost is $1,500.
What’s the best insulation for a Plano home? +
For Plano’s climate, spray foam offers the best performance — it air-seals and insulates simultaneously. Blown-in cellulose or fiberglass is a cost-effective choice for attic top-ups. Batt insulation is ideal for walls and floors during renovations. Our technicians will recommend the right product for each area of your home.
How do I know if my home needs new insulation? +
Common signs include uneven temperatures between rooms, high energy bills year-round, HVAC running constantly, drafts around outlets or windows, or insulation that’s over 15 years old. CoreLine offers a free home energy assessment to identify exactly what your home needs.
