"I had called Insulation Pros for an estimate with very short notice as well as two other companies. Conrad was the second person to give me a detailed estimate also was more then pleased to come out to my house and write me a real in hand quote. He was on time and very informative on the project. The following Monday the 2 professional men came to my house and did the job that I was promised and within the time that was allotted. Cleaned up and was off to the next shortly after seeing if I was pleased with the job. These guys are awesome. I do recommend Insulation Pros to anyone thinking about getting insulation done.
Thank you and all your staff.
Chris K."

"Diamond had an advertised inspection of house AC on Angies list. So I bought the inspection through Angies thinking it was for the unit its self in the attic, but it was not it was for the condenser outside. I contacted Diamond and asked to have the work done at that time I got a description of the actual advertised work. I scheduled the service anyway, but prior to Diamond showing up the drain in the celling plugged up and started to over flow into the catch pan that just happened to be rusted out. As a result the water ran from the pan and started to leak through the celling. I called Diamond back that they sent out a tech. He unplugged the line and informed me the issue with the pan. The tech stated that he would take the measurements for the pan and would turn it over to the office and they would contact me with the costs. I called about the pan and they gave me the estimate on the pan and I had them schedule the work. The tech returned later with a helper and replaced the pan as scheduled. I then called back to set up a schedule for the original service which was done the following week. I paid with my credit card not knowing the card number had been stolen, and I was buying stuff in China so I called Diamond and told them my issue with the card, and if it did not go through I would have to give them another card. As it turned out the card was canceled prior to Diamond being paid, the person on the phone was very understanding, and helped work the issues. Diamond personnel were very responsive, Professional on the phone, as well as completing the service, and had a good understanding of the work that needed to be done and took the time to explain what was going on. I would use them again. (If you have a metal drain pan in your attic you might want to learn from my costly lessen and have it replaced with the newer type pan it might save you from having to replace the celling drywall and repaint. Mine was right over the stair well going to the second floor so it turned out to be quite a job to clean up)

"Everything with this installation was flawless. Willy and his team were punctual, professional and extremely knowledgeable. We are thrilled with the work performed by Willy, Matt and another tech (sorry, do not have his name). Paul was our contact with Ray O. Cook Heating and Air. He gave us all the information we needed to make a decision and was quick to respond to questions we had. Within one week we saw Jeremy on an emergency call (within 45 min.) had an estimate, and installation. We would highly recommend this company.

"Outstanding quality, especially in custom designing what is called a cricket flashing to go around a chimney, the corner of the house and a valley which all converged at the same point.
Once the old roof was off, we found approximately $1700 worth of dry rot that needed to be replaced. I felt the crew, particularly Mike Gibbs, did an excellent job of helping me understand the problems and then pick the best solutions to correct the problems. Their price for the extra work was extremely fair and the again the quality was excellent. We ended up replacing all of the fascia boards and the final result looked better than the original (and it was Mike's idea of how to do it).
In addition to the roof, they blew in some additional insulation in my two level attic to bring it up to an R-38 rating. There were two spots that I felt might have been just a bit short and they returned promptly and filled in those spots by hand ... no questions asked.
For what it might be worth, the building inspector, when I told him the work was done by Brazil, sort of muttered under his breath "Good, they do it right" as he climbed the ladder to look at the roof.

"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."

"It went rough, but we were both at fault. Had to say that first. But I am mostly satisfied. The outside sales person was on time for the walk through. He was nice and seemed knowledgeable. He had a lot of prior experience as a laborer before he became a sales rep. He was able to present his company and offer a quote on the spot. I agreed and gave him a deposit. Off we go. Right? Well, he based his quote on 700 square feet when it was actually 1100. That's why his price was low. You would think that I got a deal. But no. The labor crew only showed up with enough insulation for 700 SF. Not enough. So here is what we had to do. Introduce Jose. The lead man on the project. If it were not for him, it would have went south in a hurry. Turns out that Jose is a good person with a soul, and I am happy to "work with" a great person like Jose. APP is lucky to have him, and I hope they are taking good care of him. Just so you don't think I am fake, the "helper" that Jose had that day was worthless. Didn't want to work because he is a 20 year old kid who was out all night drinking and chasing girls (or boys), and was hung over. I did more 90% more work than he did (yes, I helped Jose. I have a good soul too). I let Jose vacuum out the old stuff, then I made him stop. He understood. Come back when you have 1100SF of insulation. Right? Before he took off, Jose up-sold me on insulating the bottom of my house (in between the floor joists under the sub floor)(under the house), applying a radiant barrier in the attic and switching from blown in cellulose with the pink panther batts. I ended up insulating under the house by myself. Nice. I communicated that to APP, but it got lost in translation. When the day arrived that Jose returned with 1100SF of material to finish the job, he showed up with two helpers. BTW, I had to request the APP office to please make sure Jose was who they sent to complete my job. Regardless of my implicit instructions that I subsequently made with the APP office, that I changed my mind and now want blown in cellulose again, and NO radiant barrier, Jose and crew still showed up with pink panther batts and radiant barrier. Whatever. The crew is there, lets get to work. The reason I only give them a B is because they installed the radian barrier wrong (in my opinion). I did research and radiant barrier should be one inch from the roof sheeting (plywood) if it's hot southern California. They stapled it to the 2x4 rafters so it's really 3-1/2 inches from the sheeting. Not sure if it is even radiating anything at this point. I think I just wasted a $1000. Even so, my neighbor asked me who did the job, and I ended up giving them the APP biz card, so I guess that was kind of a recommendation."
