"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."

that needed to be performed, as well as a cost and time estimate to install these improvements. I appreciated being able to ask questions and have a positive and informed discussion about the issues. Dan is a very pleasant and knowledgeable "gentleman" who works very hard at explaining the tasks that needed to be performed. Dan is the one who made me believe in the Mark Group and it's ability to make these changes translate into energy savings.

When the work was scheduled to be performed, the installers were knowledgeable professionals, who showed up on time and worked long hours to get the work complete within the two date estimate.

The work was done with respect for my property and without undue interruptions. The installers were also very pleasant and informative.

Dave Condin was the final person who came to do quality control. He is an amazing and talented person. He is fun to talk with and seems to be the ultimate problem solver.

A week after the installation we are now facing a heat wave, and I can already see the benefits of this program. My house does not heat up because of the attic. The air conditioning runs less frequently, and the house seem far more comfortable.

The best part is that PEPCO agrees to a rebate off the cost of the installation. This makes the process and unbelievable bargain.

"Had stormdamage,called Impriano(installed roof 27 yrs ago)for repair.Kevin came, he thought the shingles were discontinued.A couple hrs later he confirmed & recommended contacting insurance to start a claim & advised the sales department to set up appointment.Sales rep Brendan came a few days later & gave estimate to replace the roof. He was informative,not pushy,no long presentation required,but all the necessary info was supplied.The insurance process took time.Although insurance only covered the front,due to age we decided on total replacement.Brendan was extremely helpful, supplying detailed lists of the items necessary. His help brought the reimbursement up to the actual cost of the loss.Our job was big, took 2 days, The crew worked hard to be sure there would be no issues overnight & were back 7 the 2nd day,Saturday.1st thing Monday, gutter crew came to reinstall gutters,couple days later electrician came to secure wiring from the attic fan we removed. Very good experience both"

"Wesley and team did our entire interior and rear exterior of house. Very complicated project (intricate) and time consuming. It was an entire house gut, so we dealt with a ton of subcontracts. Wesley and his team were probably the best (or at least top 3) we dealt with. Always first there and last to leave. very flexible with other contractors working in the space. Nice guys and always responds via text."
