"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"This was the second time we hired ROI Construction LLC to work on our home and they did an excellent job both times. Originally our roof was replaced and ROI did a fantastic job, going above and beyond in making sure every detail was perfect. Recently we had the roof and skylights of an addition replaced. In both instances ROI charged less than the competitors and the workmanship was high grade. I highly recommend this company."

"My house is a little wacky and the proposal was to include all of the crawl space and ceiling surface area. Sadly there was no way to know that a portion of both were inaccessible to insulate. Was hoping to fix issues with freezing pipes by insulating but that is the part they could not access. The scheduling and some staff on the phone is a little dry on the phone. The crew who came to do the job worked their butt off and were super nice. CJ, who drew our proposal, was very nice and knowledgeable. He warned me that his estimation might be a little off but the estimation of the Pepco energy saving percentage back ended up being way off after the energy audit. That made the job much more costly than predicted and I had not planned for that. He was willing to adjust the bill slightly but not significantly enough to really make a difference. Overall, it is going to make a huge difference in the comfort in the house and the crew was very professional."

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.
With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.
