"Ron Bishop came out to do our work. We had a potting bench that was is disrepair and a shutter that had blown down from a second story window. Ron got right to work and did an incredible job on the bench repair. He did a job in hours that would have taken me weeks and multiple trips to the store. He also made quick work of remounting the shutter. Ron was very knowledgeable, extremely pleasant and a joy to deal with. Also, Mr Handyman’s office did well with scheduling and communication. Nice work and highly recommended."

"I contacted JA Drywall after another contractor did a horrible job installing drywall in my home. Mr. Alonzo responded promptly and visited the home to estimate the project within 24 hours. He provided me with an estimate the next day, he was refreshingly knowledgeable and his honesty and candor was greatly appreciated. Mr. Alonzo and his team began work within 2 business days and completed all contracted work early. The work was done perfectly, the walls are ready to paint. If professionalism, knowledge and a job done right is what you are looking for JA Drywall is the company to hire., an excellent experience"

"Alpha & Omega PMR did a good job with repairing my window I was having a draft come thru my front window and because the window balance was off he was able to rebalance the window and repair the spring loads as well as replace the locks and clips to repair it, saved me a headache of replacing the entire window frame. I highly recommend his services, legit and honest work. 10/10"

"Regarding the first job to replace the shower door rollers, David called me the night before to confirm what was needed and said he would call me the next morning when he was on his way. He arrived on time and immediately got to work. Because of the design of the shower door assembly, Dave had to remove both doors and since I had already purchased replacement roller wheels, I decided to replace all the roller wheels on both doors. The doors now work perfectly. The second time I called was to fix the casement window in my living room. The lock handle broke off with the window in the locked position. I spoke to Daniel McElreavey to set up an appointment and was told he doesn't do work in Philadelphia, but he had a handyman he works with and would relay my problem to him. He said he was meeting up with the handyman in about 1/2 hour that same day and told me to email him pictures of the window and lock, which I did. I never heard back from either Daniel or the handyman and that is why I gave such a low rating."

"It went pretty well. My house didn't get any warmer, because I discovered that I needed windows.  For some reason, they couldn't tell me that I needed windows. I put some plastic over some of the windows, and the change was almost instant. I would have rather put the money I spent for the insulation into putting in new windows. They were professional, and they did a good job. They just missed that I needed windows instead of insulation."

"Work went well with the exception of one mishap. While installing shingles, an Impriano roofer hammered a nail through the roof deck that punctured the copper refrigerant line to our central A/C unit in our attic. Impriano's small print in the contract states, among other things, that it is not responsible for A/C lines running under roof decks. In fact, the small print is so extensive that it is basically a get out of jail free card for just about anything that could go wrong. Perhaps this is standard in the industry. Horizon Services had installed the A/C unit and lines, The copper tubing was not shielded as apparently required by Lower Merion Township's code. So of course Impriano took no responsibility. The Lower Merion Twp. code inspector did nothing. Finally after much arguing with Horizon Services I had to pay them $1800 to replace a section of copper tubing so that the warranty would remain in force on the rather new central A/C system that they had installed. Very frustrating that the roofing job ended up costing me an extra $1800 and no one would cut me a break. However, all other aspects of the roof replacement went well. The Impriano crew was hard-working and we are very happy with the new roof. I am often in our attic because we store things there. So I would notice any leak from the roof. More than a year later there have been no leaks. So although I had a bit of bad luck, I would still recommend Impriano Roofing. I know now to pay more attention to anything that is close to the roof deck on the inside. Only wish the roofer had."
