"Dap & Son were extremely knowledgeable, very professional, and always on time. We had to over 4500 square feet of insulation that had to be blown in. The project was completed with an extraordinary and high level of expertise. The work done was outstanding! We live in a HOA located in the South Loop which requires a number of prerequisites, and Dap and Sons met them all."

"Got an estimate for digging a trench (with pipes that conduct the water into the sump pump) on the inside of the basement walls and then installing a larger sump pump.Professional: came when he was supposed to, was not trying to push me on it or to sell me on more than I needed. No pressure, unlike another more expensive company from whom I got an estimate. IF we decide that our basement water is serious enough to warrant this waterproofing, we will use this company."

"Their service went very well. They came out for the estimate very promptly and the price was great. They showed up on time for work and fixed everything. When I pointed out something they missed, they stayed late to fix the issue. We have had rain since and have had no issues since the repair."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."
