    Excellent job, very clean and curious! The insulation made a HUGE difference. We had a supplemental window AC upstairs to keep the upper level cool, without it it was unbearable. I literally removed the AC the next day, the upstairs in now as cool as the downstairs!

    Gustavo responded fast. He performed very thorough inspection of our attic insulation and provided comprehensive explanation of the proposed work at a competitive cost. The work itself was performed very professionally. Highly recommend him.

    Gus was always on time or early and he was thorough and very professional. Gus laid down drop cloths so he wasn't walking on our carpet and was very clean. He had our house reinsulated and a new attic fan put in, in around 3 hours. Our house was literally 10 degrees cooler after having Gus come in. We can't wait to see the savings on our comed bill! Thanks Gus!

    Gustavo was very clear about the work that needed to be done, attic insulation package including baffles, sealing vent exhausts and 12” of blown in fiberglass insulation. He finished the job within the time frame that he quoted. The price was reasonable. I’m very happy with the job he did.

    Gus came out to do the insulation in my attic and did an excellent job. The quote and work that was promised was spot on. He even did a wonderful job in covering up the door or the lid for the attic entry with good amount of insulation. After the work was completed, the temperature in the house is much better, whether in Heat or Cold settings. We are only turning on the AC for about couple of hours and the temperature holds throughout the night. Its sooo good now. I believe the electricity bill is gonna come down a lot this year. Gus is great. He also cleaned up after the work was completed. Very very excellent job. Highly recommend Weather Shield Insulators.

    Looking For An Honest Insulation Person Gustavo Is Your Man
    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.

    Excellent Service and Honesty In Representation
    I appreciated the timely manner my inquire was handled. I met with Gustavo the next day. He was on time and explained what he was going to do. Gave my options. Explained the options and the pros of both options. He was very knowledgeable and I was very satisfied with the insulation service he provided in my attic. When he left there was no mess for me to clean up. I would highly recommend Gustavo to family and friends.

    Gus is Great!
    Gus did a fantastic job adding insulation to our attic. He gave a free estimate (a very fair price) and explained clearly all that he needed to do. On the day of installation, he arrived on time and left the house clean and neat. Insulation is a messy job, but you'd never know he was here except for the attic itself. Gus is friendly, quick with communication, and is a consummate professional. I recommend him highly.
