Hear from Homeowners Who Slashed Their Bills

Miller Attics has been transforming drafty, expensive houses into energy-efficient homes with expert, certified teams that prioritize your comfort and your wallet.

I had a fantastic experience with Miller Attics! From start to finish, Rafael’s communication was clear and timely, making the entire process stress-free. The team delivered excellent service, kept the work area clean, and completed the job with great attention to detail. Everything was done exactly as promised, and the results exceeded my expectations. I highly recommend Miller Attics for anyone looking for reliable, professional, and high-quality work.

Highly recommend this company! From the initial inspection to the final walkthrough, everything was handled professionally and thoroughly. We got quotes from three different companies, and this one offered the most reasonable price without cutting corners. They were very flexible with scheduling, finished the attic and crawl space in one day, replaced air ducts, and installed dampers—all done carefully and efficiently. We’re extremely happy with the results and would absolutely recommend them to anyone needing attic insulation work.

Awesome service! We had a rodent issue that no company could solve in over 5 years but when Al came over, he did a thorough inspection of the attic and crawl space and took a look all around the house and found multiple entry points that were never brought to our attention! The crew was pleasant, polite and clean. Miller Attics replaced all of our insulation throughout the house and now it’s rodent free and we rarely even use our HVAC. What a great result! I would definitely recommend anyone to this company!

We had rodent issues in our attic and upon inspection, we needed to replace insulation and air ducts which still contained asbestos. Rafael explained everything in detail, walked us through the process and showed photos. The service was fast (done in less than 2 days) and the crew set up containment properly. Rafael was responsive and even extended a payment plan. We’re happy with the service and would recommend Miller Attics.

This company appeared on my Facebook on 1/7/2026. Raphael called within 5 mins. We scheduled appointment for 1/8. He was punctual and great estimate. As a female I didn't think he was ripping me off. He had pictures for me before and after. He was clean and professional. No mess behind. I will recommend him for services to my family and neighbors. Very very good service

Miller Attics was great to work with. The crew was courteous, professional and provided excellent customer service from start to finish. We were really impressed with quality of the ductwork replacement in our garage, attic and crawl space. Highly recommend!

Raphael and Ben were fantastic. They did our insulation installation and air sealing in Walnut Creek. They were a great team—efficient, clean, and respectful of our home. We would definitely use Miller Attics again.

The service was phenomenal. They came in cleaned out my attic and crawl space, did a phenomenal job. They were very careful about cleaning up after themselves. They went the extra mile to make sure all small openings around the house were covered with mesh. Highly Recommend

Common Questions About Insulation

Our insulation experts have the answers to help you start saving today. Contact us now to speak to a specialist.

Most homeowners see a reduction of 15% to 30% on their heating and cooling costs after upgrading their attic insulation and sealing air leaks.

If you have moisture, mold smells, or cold floors, yes. Encapsulation seals out ground moisture, prevents rot, improves air quality, and makes your home easier to heat and cool.

It depends on your home, but blown-in cellulose or fiberglass is typically the most cost-effective way to achieve high R-values and complete coverage.

Absolutely. High-quality insulation acts as a sound dampener, significantly reducing noise from outside and between floors.

Not always. If it's just old but clean, we can often add on top. However, if it’s wet, moldy, or has rodent waste, it MUST be removed for your health and safety.

We check your insulation levels, identify air leaks, inspect your crawlspace for moisture, and use thermal imaging to see exactly where you are losing energy.

Most attic upgrades are completed in a single day. Full crawlspace encapsulation typically takes 2-3 days depending on the size and condition.

Yes! Many utility companies and federal programs offer rebates or tax credits for energy-efficient upgrades. We can help you identify which ones you qualify for.

Signs Your Home Needs New Insulation

Ignoring insulation issues costs you money every single day. If you notice any of these signs, your home is likely under-insulated or poorly sealed. Miller Attics provides fast diagnostics and permanent fixes to restore your home's efficiency and comfort.

Sky-High Energy Bills

If your HVAC is running constantly but your bills keep rising, your insulation is failing to do its job.

Uneven Temperatures

Rooms that are too hot in summer or freezing in winter indicate poor attic or wall insulation.

Pest & Rodent Presence

Droppings or smells in the attic or crawlspace mean rodents have compromised your insulation and air quality.

Musty Crawlspace Smells

Odors entering your home from below are a sign of moisture, mold, and rot in your crawlspace.

Constant Drafts

Feeling air movement near walls or floors? Your home is leaking conditioned air and sucking in outside pollutants.

Cold Floors

Lack of crawlspace insulation makes your floors uncomfortable and forces your heater to work twice as hard.

Mold or Mildew Growth

Visible mold in the attic or crawlspace is a serious health risk that requires immediate insulation removal and remediation.

Aging or Settled Insulation

Over time, insulation can settle, sag, or degrade, creating gaps that allow conditioned air to escape and energy bills to spike.

Excessive Outdoor Noise

Proper insulation acts as a sound barrier. If you hear every car passing by, your walls are likely under-insulated.
