Get matched with top soundproofing contractors in Arlington Heights, IL

"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"speedy, professional, and cleanup very well"

"Our concerns were listened to with respect and knowledge. The crew was prompt and efficient. I would recommend this company for your insulation needs."

"Sales person was great! He was able to squeeze me into the schedule since my job was fairly small. Installers were good but some of the patched up holes are still visible. I had to hire a drywall person to level out their work"

"Tom did a great job with our repair. They listened and didnâ  t try to upset me. I will definitely hire them to do more work next year."

I have an apartment building in which the garden unit had previously suffered water leakage.  I had the outside sealed previously, but wanted to get the inside sealed while the apartment was empty.  Chuck came out and offered three different solutions all with various price points.  We agreed to sealing just the inside for now, and if there were future leaks, we would consider the alternate solutions proposed.  In all 6 cracks were discovered.  Chuck had the cracks sealed and each of the tie bars sealed. 

I will be using them again for my other apartment units.

"We have had leaky basement walls in multiple locations for the entire 30 years of living in our home. Our basement was poured with Insulated Concrete Forms (ICF) made of Styrofoam. Apparently, it wasn’t a good choice or wasn’t poured properly."

"Trying to execute a major outdoor renovation project during a time of global supply chain disruptions poses many challenges. Happy to report that Mal and PHI navigated that rocky path very well. Mal kept us informed of the many changes coming from the supplier as far as colors and delivery. It was a long process...8 months between signing the contract and having the work completed. In the end we are very happy with the product and the quality of the work. A major windstorm hit the area the day after the work was completed and put the installation to the test. Everything held up perfectly...no loose bits flapping on the house or flying around the yard. In researching this project ahead of time, we had spoken with many friends who've had their siding replaced and none of them were especially happy with their contractor. We had the best experience with Mal and PHI. Highly recommended."
