How Long Does It Take To Install Attic Insulation?

If you're looking to book a larger or more complex project, particularly if you require commercial services, this can take a full day or longer, depending on the scope of the job.

OUR BLOWN-IN ATTIC INSULATION SERVICES

We install blown-in attic insulation, which we've identified as the right material for the vast majority of Lewisville-area homes. It's ideal for filling cavities and covering irregular framing, getting into corners that batt insulation misses and adding R-value fast.

We want to give you the best results, and that's why we don't push spray foam insulation upgrades if you don't need them, and we don't sell batt rolls that leave gaps!

THE INSULATION MATERIALS WE USE: CELLULOSE AND FIBERGLASS

We primarily recommend two insulation materials for homes in Lewisville: cellulose and fiberglass. We've found that both perform well when they're installed properly (which we guarantee when you choose us!).

If your attic has condensate lines, a history of moisture, or HVAC equipment that could leak, we usually lean towards fiberglass insulation. But if your budget is the priority and your attic is dry, or if you want the highest R-value in the least depth, we'll recommend cellulose insulation instead.

We'll walk you through both during your free assessment, but here's a closer look at how they compare:

Bad attic insulation increases your energy bills and forces your AC to run longer than it needs to, which, in turn, can shorten its lifespan. It also creates uneven temperatures throughout your home, especially upstairs, and allows heat from the attic to transfer into your living space. Upgrading your insulation properly should reduce that heat transfer significantly, so you can improve energy efficiency in your home and put less strain on your equipment.

Lewisville sits in a hot, humid climate zone where the recommended attic insulation level is R-49. Many homes built in the 80s and 90s fall well below that today due to settling. If you can see your ceiling joists when you look into your attic, there's a good chance that you don’t have enough insulation. Bringing your attic up to the right level should make a noticeable difference in your comfort at home, as well as your energy usage.

The cost of attic insulation in Lewisville depends on factors including the size of your attic, the current insulation level, and whether any removal or air sealing is needed. As local insulation contractors, it's our job to keep our pricing competitive. We've found that most installations cost between $1,500 and $7,500, with straightforward jobs usually costing between $1.50 and $2.50 per square foot. We'll always provide a free estimate when you get in touch, so you'll know exactly what you’re paying in advance.

Yes, if your attic is currently under-insulated, upgrading it with more or better insulation can reduce your heating and cooling costs. With your HVAC system running less to achieve the same temperature in your home, your energy bills will be lower. High-quality attic insulation can also improve your comfort by minimising the effects of the outdoor temperature inside your home. It can even improve indoor air quality and prevent damage from condensation and moisture.

Yes, if your home qualifies, you may be eligible for rebates through Oncor’s Take A Load Off Texas program, which can return a portion of your project cost. Federal tax credits for insulation ended in 2025, but new state programs may become available in the future. We’ll explain what applies to your home during your assessment, so you can take advantage of any rebates or incentives that are available to you.
