Rated 5 Stars for Quality & Service

★ ★ ★ ★ ★

Castillo Insulation did an amazing job insulating our attic in Pflugerville. We noticed a difference in our home’s temperature the very next day and our A/C doesn’t run as much. The team was on time, professional, and left everything clean.

Frequently Asked Questions

Everything You Need to Know About Insulation

What types of insulation do you install?

We specialize in blow-in cellulose (made from recycled newspaper) and fiberglass insulation. Our services include attic insulation, wall insulation, and cold floor insulation for residential and light commercial properties.

How do I know if my home needs new insulation?

Signs you may need new insulation include high energy bills, uneven temperatures between rooms, drafts, or visible deterioration in your attic insulation. Our team can perform an inspection and recommend the best solution.

What are the benefits of insulation installation?

Proper insulation helps reduce heating and cooling costs by up to 50%, keeps your home comfortable year-round, reduces noise, and can even improve indoor air quality.

Is blow-in cellulose insulation safe and eco-friendly?

Yes! Blow-in cellulose is made from recycled newspaper and treated with a fire-retardant solution. It’s a sustainable, safe, and energy-efficient choice for homeowners looking to lower their environmental impact.

Do you offer insulation replacement services?

Absolutely. We remove old, damaged, or inefficient insulation and replace it with new, high-quality materials to maximize your home’s energy efficiency.
