A year later and no improvement. I ingnored the red flag when David looked suprised when I mentioned that I had cameras. He looked suprised and asked me where the cameras was located. I wish I had checked the cameras and I would have seen that he did not install the insulation as expected. Do you research on his business, the reviewers and check his business license on the State website. Take note that most of the positvie reivew are women. Don't base your decision off Angies review. read more

This guy is the real deal. I needed my attic insulated. I requested a quote. 1. David arrived on time to give me the quote. 2. Gave me the quote later the same day. 3. After reviewing other quotes and services I hired Dap and Son. David was able to do the job at my convenience. 4. He arrived right on time. Asked me if I wanted to see the work before and after (my attic is very difficult to get to and frankly I had never seen it in its entirety before). He took care of problems he found in the attic while doing the job, at no extra charge. 5. cleaned up after the job. I would use him again. Arlene - Chicago read more

I hired David Dap to install blown in insulation to bedroom walls in a portion of my home that was built in the 1960's. Those bedrooms were extremely cold in the winter and hot in the summer. David's suggestion was to drill coupons from the drywall, blow in insulations to fill inside the studs, and reinstall the coupons with drywall "mud". I am very impress with David ability and the quality equipment he uses. His pricing, in my opinion, was very competitive and his follow-up from arrival to completion was as he told us we should expect. The one recommendation considering insulation installing, in an existing home, is the time of year and the follow-up cleaning of the rooms/outside. I suggest you consider before winter conditions set in. My wife and I hired David this winter (yes, snow and other winter conditions were in play) and we had limited space to move the items in each bedroom. David tarped our items and vacuumed up each room/hallway/pathway outside. Still, as you should expect, additional cleanup will be required. In my opinion, it would be much easier Spring, Summer, or Fall. I gave David the maximum number of stars for his work. I would recommend David to anyone considering adding insulation to their home.

Called and was able to schedule and estimate. He came by and was super professional. When I called to schedule the actual installation he dodged me several times and to this day never got back to me. Don't know what happened. No explanation provided. Don't waste your time. read more

Professional and prompt, but grossly overcharges I think. Never writes anything down for any reason which makes one suspicious. Did come and do part of the job verbally promised, used cheap materials. However will not use again. read more

This winter our pipes froze due to poor insulation in one wall. On short notice, David and his team came out to evaluate the situation and blow in some cellulose insulation into our walls. David showed us what he was doing as he was doing it, and cleaned up after himself (cellulose insulation can be pretty messy). He even repaired the drywall where the plumbers had cut into it to expose the pipes. All we had to do afterward is sand around the edges of the patched drywall and paint. I would recommend David and his team for any insulation job. It was about $1200 for two walls but it really depends on the job YMMV due to wall size etc. read more

Totally impressed with Dap and Son Insulation and Soundproofing crew. Aside from being prompt, and doing phemomenal work, the clean-up left me amazed. I am fortunate to have encountered such a wonderful group of hardworking guys to provide my insulation needs. Thoroughly pleased! read more

Had Dap and Son do insulation in my Tudor home with pitched ceilings. I was at my wits end thinking no one could fill my crawl spaces and storage areas with adequate insulation. Dap and son more than exceeded expectations and for much less than I expected. I look forward to cut ting heating bills as it is much warmer since they did their work!!! read more

Read about Dap & Sons on Home Advisors and decided to hire him. He does exceptional work and his are reasonable.

Could not have been better. I interviewed 3 companies and got estimates from all. All of them were listed on Angie's List and also through other "handyman" & "home improvement" websites. I chose DAP & Son because the owner, David, did a lot of things right. He listened. He explained things to me. He showed he knows his business. My town requires a building permit for doing insulation. A lot of towns do not. He had no problem with that (another of the local companies I got an estimate from did not want to do that). David took care of it. Note: In my town, you have to be registered with the town and show: Surety Bond and Certificate of Insurance. But each time a building trades company registers with the town, it is OK for them to do business for the next 12 months in the town, so the money they pay to register lasts awhile. The surety bond was important to me. A certificate of insurance protects the tradesman's company. A surety bond protects me - the consumer. David and his team of 2 other men got here early (8:15 a.m.) and were done and gone by 12:30 p.m. They put down tarps, they vacuumed as they went - during and after they were drilling into the walls to blow in the new insulation. They called me over several times during the process so they could show me what they were doing and why. When David needed to check an inside wall from the other side, it meant walking into an adjoining room. He asked my permission to do that. Very respectful. I like that, too! They cleaned everything up, were as nice as they could be, and it looks great. Now I just have to wait for the painters that I am contracted with to come and make it all beautiful. I would recommend David Poole of DAP & Son. read more
