The entire process was excellent! They added additional insulation in my attic, and were extremely friendly, responsive, knowledgable, and professional. A great service at a great price.

5-Star Review: Fantastic Blown-In Attic Insulation Service including Exhaust Fans
I recently had blown-in insulationinstalled in my attic, along with 4 Exhaust Bath Fans and the experience was outstanding from beginning to end.
The Gus & team were punctual, professional, and clearly knew their stuff. They explained the benefits of blown-in insulation—especially how well it fills gaps and improves energy efficiency—and helped me feel confident in the decision.
The installation was quick, clean, and completely hassle-free.
If you’re considering blown-in attic insulation, I highly recommend Weather Shield Insulators service (Gus). Great quality work, friendly staff, and noticeable results. Couldn’t be happier!

I am pleased. The job was very well done. All my questions and concerns were promptly addressed. Gustavo is knowledgeable, professional and reasonable. It is a small business without any sales people or subcontractors. I highly recommend it.

Everything went very well. Gustavo got back to me 15 minutes after I made my inquiry. We made an appointment for the following night to see my attic and what insulation would be used. Gustavo showed up at the appointed time. Looked at my attic measured and pointed out problem areas. We discussed my options, I asked questions and I told him I had two other people I would be seeing. However I would let him know either way. Gustavo got the job and his work was excellent. No mess when he left. I felt the warmth in the house the next day. I found Gustavo to be honest, knowledgeable, and efficient. I would definitely recommend him to family and friends. I'm very satisfied with both the price and insulation job Gustavo did for me.

We are doing a Gut Rehab of our 30 year old home, and I needed an insulator to replace the insulation in selected walls and ceiling areas caused by the construction. I choose Weather Shield Insulators for my project as I was first impressed with their response for my request for an estimate, secondly by Gus' professionalism when he showed up for the estimate. Gus did a thorough evaluation of our home and pointed out areas that the insulation has settled and would require additional insulation. His estimate to completely add a layer of insulation to my attic, to bring it from a R-30 rating to a R-49 rating, surprised me at its affordability.
We discussed scheduling, and even though Gus' install schedule was packed, he found a way to fit our project into his schedule to make it work. When it came time to do our installation and repair, Gus and his team showed up as promised and installed as indicated in his proposal and left my property as he had found it.
I spent over 45 years in the construction industry, and would rate the quality of service, provided by Gus and his company, right up there with the best of them.
