Plainfield, CT∙ Drywall/Paint/Repairs

Wow. I will start with that. Cornerstone did an amazing job in my basement in crunch time. I needed walls fixed, door replaced, railing repositioned and painting done in 5 days. Not only did they provide professional consultation and competitive pricing, they completes the job in record timing. Zach stayed in communication daily. My husband and I are extremely pleased and will be repeat customers as we upgrade our home. I highly recommend Cornerstone Home Improvement.

Plainfield, CT∙ Deck Remodel

Our experience dealing with Zac and crew was great. We had several projects and each was handled professionally and in a timely fashion. He kept us informed every step of the way and was able to work around material delivery issues, without impacting the completion date. We highly recommend Zac, and have already requested an estimate for another project.

Plainfield, CT∙ Bathroom Remodel

Zac did a wonderful job on our bathroom remodel. The subfloor had a rotten spot and the pine flooring needed replacing. Zac did an excellent job making, staining & finishing the tongue & groove pine flooring and cutting the marble top on the vanity to make it fit the space and went above and beyond finding/getting the parts needed for the sink and toilet installation. We are very pleased with how everything came out and will definitely contact him for other projects.

Cornerstone Home Improvement was super easy to work with. Installed french doors in our home for us, and did a great job. Came the day they said they were going to, and finished the job quickly. Pricing was very fair. I would highly recommend!

Thank you so much for the great job you did repairing the roof on our shed. You left the jobsite area cleaner than you found it and the quality of the work performed was top notch. Please feel free to use me as a reference for any of your potential clients.

Dayville, CT∙ Farmer’s Porch

Zac and his crew did an excellent job taking an old tiny and tired front porch and giving us a beautiful spacious farmer’s porch. He was great to work with, stayed in contact throughout the whole process. We went back and forth on design ideas and he understood what we wanted. The end result far exceeded expectations. He was recommended by a friend and I’m glad I took him up on the recommendation. I will absolutely come back to Zac and Cornerstone in the future!

Lebanon, CT ∙ Window Repair and Bathroom Vent

Log cabins pose quite a challenge, and the Cornerstone team took it on like it was nothing. We had to pivot a bit when we found out the damage was more than expected but that didn’t slow them down. We also had them install a fan in our bathroom and the fixture is seamless, as well as the fixture on the roof for venting. Thanks guys!

Storrs, CT ∙ Roofing/Appliance Repair

Roger and I needed serious help with our 12×20 sunroom roof leaking whenever it rained. Thanks to Zach and his expertise NO MORE LEAKS! With all the rain we’ve had we were dry!

Zach totally rerouted our dryer ventilation under our home. Huge relief, with a shorter better connection and more. Zach is trustworthy, very professional. Zach is our ‘go to guy’. Great job!

Moosup, CT ∙ Deck Build

As a customer of Cornerstone Home Improvement, I am blown away by the quality and construction of my new deck. From the start, Zach provided excellent customer service in terms of finding competitive material prices, addressing any concerns I may have had, and communicating effectively. Cornerstone’s employees were very respectful of my property and even went as far as fixing a leaking spigot they noticed needed tuning. I am thankful to have worked with this company and I plan to use their service for other home improvement efforts down the road. I would recommend their work to anyone looking for a solid price and quality craftsmanship.
