Customers say: True professional

"They did a very thorough crawl space clean up and detailed and well secured installation of the vapor barrier . They were honest, and efficient with positive energy. The issues are with communications from the office. They could be more professional, timely and thorough."

"They put in sound proofing insulation in a wall in my furnace room. It didn't really work, but it wasn't their fault due to the wall configuration. But they were very professional and did the best job they could due to my circumstances. I would hire them again."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

"after several reschedules on both of our parts, the Saturday came that the weather was good and both parties schedule worked. The work was to begin at 1200noon, I got a call at 1100a stating the owner was in Beaverton on a leak job that turned out to be bigger than they thought and could someone else come look at the work to be done, I had some errands to run but would be back by 200p, reschedule arrival to 200p. By 430p, no call and no workers. I called to John who informed me his lead roofer was on his way and should be at my house in 30 mins or so,. The worker had locked his keys in the car but was picking them up and was on his way. By 6pm, I called again, got a message machine and was frustrated. Almost at the same time the worker showed up, then John called back while I was showing the worker around. He got on the roof, climbed back down, got a caulking gun, climbed back up, total of 40 mins later he was at the door telling me I had a few raised nails, he had caulked around them and caulked down the shingles. I asked a few more questions about the life of my roof and what did he think of the condition. He basically referred me back to John. John never even saw my roof. I have not had a good rain yet to see how the work was done, me guess is it will leak again. The roof was not cleaned off, the gutter nails were not checked-all of which were supposed to be covered by the Angie list coupon. I knew when it was Saturday evening after a long day of roofing elsewhere, my service would suffer and it did.
