Shawn from ProStar did a great job. Excellent customer service from start to finish. He explained a few repair options, replaced my sink, and fixed the shower water handle issue quickly and professionally. Honest, helpful, and easy to deal with. I would definitely recommend ProStar’s services.

Prostar guys replaced our old furnace and hot water tank and the experience was seamless. From the initial quote to the final walkthrough, the team was incredibly knowledgeable. Professional, transparent about pricing, and they even cleaned up so well you’d never know they were there. Top-tier service!

I once again needed Prostar assistance and every single time they provided excellent service from the first call you make all the way till the job is complete. Darcy and Shawn have great experience and are very reliable. Amazing company. I called them to request their services and they were very friendly and polite, sent someone right away to my house to check my furnace and AC, once he arrived the service was top notch, friendly, professional, efficient and effective. I recommend them to anyone needing any of the services they provide, they always explain the options and information clearly. Thank you again for the help, you guys are wonderful and professional and I know you stand behind the work you do always. I wish I could give more stars than 5⭐️⭐️⭐️⭐️⭐️

DO NOT USE THIS COMPANY! They only get 1 star as I have to. Our House is 26 years old. We needed 2 standard outdoor water taps replaced as they were starting to leak. No obstruction to get to either tap. Water had been shut off and also drained. Took about 15 minutes to replace both taps. No lines were replaced either. Total bill $831.60! And that was for the taps that had no drain valves either. That would have been over $1000!!!!! I called and was told it’s the cost of doing business as they have liability insurance to pay for and it’s not a one man business. And they only offer 30 days warranty. Save your money and use a different company. We were absolutely taken for a ride.

Find another company! Three valves, that are housed in my washer closet, needed replacing. Two Eddytime plumbers came for the job. They took the washer out and replaced the valves. They put the washer back in but did not reattach the drain hose. A Plumber! Didn’t reattach a drain hose! I was unaware of this gaff and the next time I did a wash, the water drained into my downstairs neighbour’s home. Lazy, shoddy workmanship.
