Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Quick quote. Bit weird where you sign on and just wait for them to call you to do the job. Work done extremely quickly and done very well. Would advise having your own opinions before engaging in design.
Our Eavestroughs were 30 yrs old and needed to be replaced. A neighbour replaced theirs and we were impressed with the results. We contacted Mark and he came to our home on the weekend to fit our schedule We agreed on the contract and today his employees came at 7:30 AM to start the work. They finished this afternoon and my wife and I are very Pleased with the results The workers cleaned up and took away the old eaves As our old eaves had leaves in them from the trees, the leaves fell on our grass. The workers blew all the leaves away too Phenomenal service Phenomenal product Phenomenal pricing Highly recommend this company Give them a call You wont be disappointed
Terrific service, from first call to last exchange. Good quote, with smart rationale for bigger eavestroughs. Good follow up. Was impressed with the speed of response and speed of job completion. A great company with great service. You won't go wrong with them.
I wasn't sure what needed to be done with my father's roof and the most important thing to me was finding someone I could trust. The roofing scene can be tricky to navigate. I've had bad luck in the past. Ontario Downspout Services had been recommended by a neighbour. Harvey answered the phone and he was a calming and thoughtful soul who started the whole process on a promising note. Mark was awesome. He arranged to meet up with me in record time to discuss the project. The terms were fair and the contract was thorough. We figured the job would be 2 days... 3 at the most. The whole thing was done in less than one day. The crew were ninjas. Within a matter of hours we had a fabulous new roof and eaves and downspouts and the other bits that I can't name. And they left the place spotless. I can't recommend these guys highly enough.
Mark and his crew did a great job replacing the flat roof on my house and dealing with a leak I had into my living room by replacing a strip of roof and eaves trough along a side of my house in an awkward narrow area between my house and my neighbours. Mark shared photos as they removed the old materials so I could see the problem areas and understand how they were fixing them and then sent photos of the completed work. They worked quickly while also protecting my house and cleaned up well. I highly recommend Mark and his crew.

Worth checking yourself
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemized quote (parts and labour separately) before agreeing to major work.
Gas work is licensed separately from general plumbing in every province. Make sure anyone working on a gas appliance or gas line holds the gas certification your province requires, and ask for proof of that certification before they start.
