What Our Clients Say


This was the second time we've used Renovax. The first time we used them (replaced windows and doors) and it was such a good experience, we had them back to replace the columns on the outside of the house. Once again, flawless execution, great communication and great quality of work. Highly recommend!

Tracy Rothmeyer

Jack was wonderful about getting back to me right away about the loose siding that was caused by a storm. The job was scheduled promptly. The gentlemen that came to do the job communicated what they planned to do and completed the job efficiently. Great job!

Patricia Welegala

Renovax did an incredible job on our two story home. Our home is 100% siding and could not believe how fast and efficient the crew was while providing perfect quality. Jack is tremendous to work with and I am having them do further work. Pricing is very reasonable and Renovax more than delivered. HIGHLY RECOMMEND!

Ryan Skahill

I've used Renovax twice this past year for a project: 1) to install Hardie siding and 2) to replace gutters, soffit and fascia that turned out to be too far gone. They are responsive, reasonably-priced, easy to deal with and their work product is excellent.

Wendy A

We replaced 28 windows with full frame construction Windows by Andersen. They were installed by Renovax who did an amazing job. The job was done impeccably. Roman and Bogdan were the installers and they were great. End of every day they cleaned everything up. We couldn’t be happier. Highly recommend Renovax.....

Marcia Roth

Jack and his team at Renovax have done multiple jobs for me and my family over multiple years. They do very solid and high quality work and have a fair and transparent process. I am actually going to ask them to do an additional job in the coming months.
