"The Complete Home Solutions' crew that handled my attic's insulation project was informative, professional and timely. They explained their processes start to finish, answering all questions along the way. Even in the face of obstacles due to the nature of my unique attic, they overcame and completed the project on-time and to complete satisfaction, absolutely astounding job! A giant thank you to the crew; Brad, TJ, JB, Jeremy, Anthony, and Jason!"

"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."
