"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

"We recently completed a gut reno and second story addition. After engaging 10 different contractors, MP was the most communicative, interested, flexible and competitively priced. MP has a large in-house team of experts that work efficiently and adapt to the home owner’s needs and preferences. The employees worked 6 days a week and took great pride in their work. They were personally invested in our project and wanted to make it the home of our dreams. The team includes an amazing designer, Nataly, who helped with selecting finishes. The onsite foreman, Adriano, demonstrated expertise and kindness. Seichelle and Marco did an excellent job with operations, ordering materials and problem-solving. We have been back in our home for 10 months. Anytime I have an issue, Seichelle and the team have addressed it. They have gone above and beyond what is expected. We could not be more pleased with our project. We strongly recommend MP for your next project!"
