"I had my attic areas sprayed with foam insulation by Southern Twist Spray Foam. The owner, Marc, was incredibly helpful in explaining the process and offered fair pricing. He was easy to work with and down to earth, making the entire experience smooth and stress-free. Since the installation, I've noticed a decrease in my electric bill during the summer months. I am a very happy and satisfied customer and highly recommend Southern Twisted Foam Spray for anyone looking to improve their home's insulation. I know they offer other services such as lifting driveways etc with foam, but we didn?t need that service yet. Thank you, Marc, for your excellent service!"

"They were a bit over the rest of the company’s that I had out. But the pease of mind that I had knowing that they were going to do it right was worth it. During the bid Mike answered all my questions before I was even able to ask them. Made a great impression on me. They also worked well with me removing my old insulation myself. PLUS , they hauled off the old stuff for me at a great price!! Thx guys!"

"Strongly recommend getting an energy audit completed on your home, especially when it's complimentary, thank you, Paul! There were quite a few items that needed attention in our home. The technicians Justin and Fernando were solid. They arrived on time, did a great job, were polite, and were very clean. They took before and after pictures, which shows how much I needed the work done. We went with the insulation to ensure it was at least 18 inches, the duct sealing of the junction boxes and HVAC unit, and we had to reroute the bathroom vent. We even did the optional UV-C light, which makes us feel much safer and takes a load off, especially in this current environment of being conscious of germs and all. Great technicians, great company, and solid work. Highly recommend Justin and Fernando :) The email and text reminder game is on point."

FAQs for insulation service projects in Rockwall, TX

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
