It's time for Four Seasons to help transform and improve your home!

"THIS IS A SCAM! They took our deposit and ran! Four Seasons sent over a 'salesman' who lied to us to get us to hand him over a $9000 deposit to build a sunroom on the back of our home. We were worried about fees and zoning issues with our town, and Four Seasons kept telling us all will be okay. But when our town raised zoning issues, Four Seasons refused to rectify the issues, and stop returning our calls and emails. They have ghosted us with our deposit and have not delivered any service. This is a SCAM! DO NOT HIRE THEM!"

"We had a terrible experience with Steven Kaplan. Every week he'd tell us who was coming and when and what they would do, and half of the time no one showed up and when they did very little was accomplished. For months he made promises about deadlines, missed those deadlines, made new promises, broke those, and so on. After six months of very little progress on our bathroom remodel, we finally had to hire another company to do the work. We never received many of the goods or services we already paid for."
