    Various small jobs-
    I had the pleasure of working with Richard on a wide range of home repair and improvement tasks. Richard listened closely to every detail, made thoughtful suggestions, and was very accommodating throughout the process. No matter how big or small the task, he approached it with patience and precision. He didn't just do a great job - he was genuinely good person to have around the house. Respectful, positive, and easy to talk to, Richard made the whole experience feel less like a renovation and more like a collaboration. I highly recommend him to anyone looking for someone reliable and talented. Would definitely call him again for future projects.

    Repair or maintain airconditioning-
    Needed a replacement AC unit after old one was diagnosed with a high-pressure line blockage and was deemed not worth the cost to repair. Omega Heating & Air was great start to finish, from initial conversation to quote to technician install to payment, everything was clear and done as agreed too. Highly recommend Omega Hearing & Air!

    We recently used Master Homes Contracting to renovate two bathrooms. Anton came to the house to discuss the project and offer some advice as to the design aspect of what we were doing. We found him very knowledgeable, he made recommendations as to the layout and gave us a clear idea of what the project would look like when completed. We received a detailed quotation within a few days, numerous options with pricing. With some conversation we were comfortable with the quotation and agreed to move ahead. We were then introduced to Ashley who would be our design contact throughout the project. We had done the usual visits to the home stores and to be honest were a little overwhelmed, we really needed some direction and advice. Ashley made it so easy, she supplied numerous choices, with pricing, for each of the components from tile to taps, and really helped us with every selection, for us, that expertise saved weeks of wandering the aisles trying to figure out what we wanted. Once decided, Ashley ordered everything for us and had it delivered to our house. The crew showed up to start the demo on the agreed date, immediately covered my hardwood hall and stairs to avoid any damage as they removed the debris, they were careful to try to limit the dust as much as possible but by nature its a dusty job. Execution was flawless, we did have to make some decisions as to the waterproofing behind the new shower, Anton gave us three options with and actually recommended the LEAST expensive one for what we needed. We had a vacation planned that happened to fall in the middle of the project. We were so comfortable with Anton and his crew, we gave him a key, they continued working while we were away. The project was completed just as we got back, we were so pleased with the results. Both bathrooms look amazing, certainly exceeding our expectations, they even added undercabinet LED accent lighting, not included in the original quote but they thought we would like it. They were right, it added a whole spa like look to the bathroom. The project was completed a few weeks ago but I held off on my review as I knew there would be some minor call backs, there always are with any reno. The true test of a contractor is how well they handle the call backs. A flickering pot light, a sticky drawer on the vanity, they were there next day, resolved without question, we were very impressed. We did add some extras to the project as it progressed but overall they were on budget per their original quote. As a contractor Master Homes ticked all the boxes. On time, on quote, knew what they were doing, all the assistance we needed, daily updates on the project, immediate attention to the callbacks, and probably the most important factor, Trust. We will use them again for our next project without any hesitation, there are so many horror stories out there it was a pleasure and a relief to find a good honest contractor that goes the extra mile to make sure you are satisfied with the results.
