"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"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."

"We hired ROI Construction for replacement windows and were satisfied overall. They were open to price negotiation (we had competing bids) and flexible on scope, we added shutters at a reasonable cost. One install issue came up, but they resolved it within a couple weeks. Communication was steady throughout. Would definitely consider working with them again."

"This company rebuilt a badly deteriorated cement-block retaining wall which supports my elevated driveway, repaired numerous concrete sidewalk cracks and a crumbling step, replaced an ugly, old, insecure chain-link gate with a beautiful steel door, and installed attractive brick borders around a couple of small garden spaces (after also cleaning up those weedy spaces). The price was more than fair; I'm very pleased with the work, timeliness and charming personality. I wouldn't hesitate to hire them again."
