I’ve worked with John and his team for several years in two different homes and on nearly a half dozen projects, including renovating my bathrooms, Replacing my entire back porch, installing French doors and opening up my kitchen leading directly to the patio, and now redoing my basement twice in two different homes, including a personal gym and a bar and everything has always come out top-notch. I love working with John and his team because I bounce off ideas With him and he helps me to come up with a concept and design That he knows I will like and is always looking for ways to work within my budget. I highly recommend Cooper modifications for all your home renovations.
We used Cooper for our siding project and I couldn’t recommend them enough. Importantly their communication was top-notch and everything was telegraphed exactly how it should go. This was mostly a product of my communication with Anthony. He was fantastic at driving the project forward, keeping us informed constantly sending us pictures of what was going on and asking us any questions around any options that might be available. I would certainly recommend anthony and his team and will likely use them again for other projects.
My fiancé and I moved to Milford CT about two years ago. Bought a house from the 1960s, needed some loving. Learned about Cooper Mods through word of mouth, gave them a shot to remodel our deck. This company could not be more impressive. Responsive, well priced, and the finished deck was perfect. They work around your schedule, respecting your time and finishing the project promptly. I don’t write many reviews. Highly recommend John Daley and his company. Thank you folks hope you see this.
We have roof and siding installed, all the materials are high quality and daily communication with the contractor and crews to make sure every detail has done right and look perfect, the crews are very good, from the day one, stripping out the old roof to the last day cleanup , very professional and highly skilled. We are very happy with the work
I honestly don’t even know where to start. I hired Matthew, John, and Anthony for a siding job and the experience was on another level. From the first conversation to the final walkthrough, everything was handled professionally and smoothly. Communication was always on point, they showed up when they said they would, and the quality of the work speaks for itself. The job came out amazing — clean, detailed, and done right. You can tell these guys actually care about what they’re doing and take pride in their work. What really stood out to me was the customer service. They made the whole process easy, stress-free, and just handled everything. If you’re thinking about hiring them, don’t even second guess it. These guys are the real deal.
