"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 really worked hard to find the specific type of insulation I wanted for my walls in my garage conversion. It was Rockwool R15 Comfort Batt Insulation. It makes the room feel cozy and it helps to dampen sound!!! My walls were 2 X 4 inch walls. They were able to do the work, within 7 days, from first coming to my home and giving a bid!!! That is amazing!!! They listened to what I wanted and installed it properly!!! I would recommend them to anyone needing insulation!!!"

"Tech who showed up to do inspection was thorough. Climbed into small attic, took pictures and explained what their findings were. Other inspections (I had 2 more) just popped their heads into the entrance and too my word for what may need to be done. Scheduling with Attic Construction was simple. They showed up on time (early). They let me peak up their as they cleaned up old insulation and remove rodent droppings (biggest concern). They finished within the day as promised and cleaned up after themselves thoroughly. Our home was well protected from dings/damages as they wrapped corners of walls, stairs etc. We have noticed improvement from having only 3.5 inches of insulation to now nearly 14-15 inches. They recommended a "combo" of batt insulation (Around the entrance) and blown in for the rest of the area. This allows you to pop in there with out blown in insulation falling all over the place. They also recommended and performed rodent proofing/sealing. We were sent photos of both before and after their work. I would highly recommend this company."

"This was one of the only companies who would come in and blow in insulation JUST ABOVE a new project area. Other companies wanted to blow in insulation in the whole attic, not the small addition I had completed. Like other reviews, he took before and after pictures. I appreciated that they were on-time, thorough and efficient in completing my little project."

"They did an excellent job. The before and after pictures really showed me what they did. They replaced the ducts that were damaged for less than what my a/c company was going to charge and replaced my insulation and did a lot more work as well. I am very pleased with them."

"They came on time, did the job, cleaned up, and left. They knew we had an attic door in the doctor's exam room so they entered thru the garage attic door but when they blew the insulation in, they didn't cover or protect the other attic door. Insulation fell in thru the cracks all over the technician who was working with the doctor. Since they knew the door was there I wish they had kept insulation from flying in. Otherwise I think they did a great job. It certainly made a difference in the temperature of the building on hot days."

FAQs for spray foam insulation projects in Terrell, 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.
