"It was amazing, took all day to get the old insulation out, seal the holes, and refill with new insulation. Would recommend this company to anyone looking for a professional service to improve insulation and save money on heating and cooling costs."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"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."

"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.

"Very well. Marc was very thorough and did a very good job explaining what may be wrong. He offered suggestions on how to repaint the drywall. He was extremely customer oriented and diligent. I would hire him again. He indicated some things we could do to prevent problems in future. He is a credit to American Home Contractors."

"I should have used them to the whole job, but thought I would only need the thick moss removed. so I kind of paid for that twice. I don't care. the roof (15+ years old) looks almost new. they had to replace over 100 shakes and ridge caps.
I'm over the moon how good it is.
I will have them do yearly maintenance from now on.
