"After checking out several insulation companies, I chose to hire Elite Insulation Specialist. I am very pleased with my decision. Their price was by far the best and I felt like they were very honest and straight forward. The guys arrived early to the appointment and we’re done in less than an hour. They were friendly and professional throughout the entire process. I will be recommending Elite I dilation to friends and family."

"This September I had a home energy audit through Fulkrum Insulation. They said we needed some Ductwork changes and more insulation in the attic. Since having those solutions installed, my electric bill has been dramatically lower than ever before."

"Only reason I am giving 4 stars instead of 5 is because the team left a lot of insulation for us to clean up ourselves. Otherwise, the quote was fair, they got the job quickly and accept multiple payment methods, which was convenient."

"It was great! Jorge & his partner were very prompt, courteous, and efficient. I don’t have a really large attic but 3 other big companies quoted over $4000 to install insulation in my attic. North Tx Insulation did 13 inches of new blown in insulation for $1000.00. They were neat & in and out within an hour. I would highly recommend them!"

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.
