"Mike arrived on time and began work immediately. He removed old wiring and installed all new wiring and conduit and repaired a few down spouts at the same time. He installed all new lights along the walkway, removed an outlet that was of no use and re-wired the entire front of the house including wall flood lights. Mike had to dig up flower beds etc. to accomplish his work and when he left you would not know he was ever there. He cleaned up the walkways and removed all trash. He kept in touch with me regarding progress. I have used them several times for non electrical issues also. Their communications system is top shelf.

"Everything went well ! The customer service stood out the most to me. The installers were prompt and very thorough. I would hire them again if I needed."

"Bill was very responsive, prompt, professional and extremely knowledgeable. He was even able to save me a few hundred dollars by removing one of the components that was still working from the dead unit and put it in the unit which needed fixing. He'll also be getting me a quote to replace the non-working unit. I would highly recommend Bill's company."

"Dan was great from start to finish. Being new home owners he walked us through the options available to us and found the best door for our needs and budget. Dan’s work was top of the line. He took great care when installing the door and everything turned out even better than expected. We look forward to having Dan help us again, when it’s time for our next home project!"

"

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.

"New roof was installed with excellent craftsmanship by workers who seem to be proud of their work. Sales consultant and scheduler were communicative and abreast of the progress of the project. There was much attention to detail in installing the new shingles, and necessary unexpected repairs that were identified were done without delay. The workers are efficient and effective. The areas are gone over and left spotless with followup people coming by the next day to be sure all is in order."
