    We woke up one morning to a yellow patch in our ceiling that set off a frenzied effort to find a leak somewhere in the envelope of our home. Our insurer confirmed the window as a likely source, but that this was not be covered under our insurance. On that basis, we hired MAXgreen windows to correct the leaky window that was later confirmed as the source as well as repair the surrounding envelope. From sales to install, the experience with MAXgreen windows was first class. Excellent communication, high-quality product and installers that were clearly knowledgeable and came in with a plan. We will use MAXgreen again in the future for any of our window siding or door needs.

    Build or replace decking-
    I needed my front porch fixed urgently after it was destroyed to fix a sewer pipe. Mike was fast to respond & kept me in the loop every step of the way. My only complaint is I hadn't found him years ago to help with other jobs around the house that did not go as smoothly. I 100% recommend MCF HomeAndBusiness and will not hesitate to reach out for any future work needed around the house.

He did an excellent job putting it together and I was quite impressed with him.. Very nice guy.

    I just had my sunroom roof replaced by Tropical sunroom Kitchener. The crew showed up before time and worked tirelessly all day long, times 2 days. The two men were focused on the job and clean while doing it. I'm so pleased with the job they did!! The company and construction lead hand were extremely supportive. I would recommend Tropical Sunroom!
