Thor Construction company did some hardscaping for us in our backyard around the pool. Right from the start they were responsive, they worked with us on a design that was functional for the space and stayed within the agreed budget. Their work was fabulous! The attention to detail created that special place in our backyard that we will certainly enjoy for many years to come.

Thor Construction designed and installed a new backyard deck and fence. It was completed ontime and within budget. The crew was very professional from start to finish. I would recommend them for any landscaping needs.
We can't thank the crew at Thor Construction enough for truly transforming our backyard to the space of our dreams! They were extremely kind, professional and reliable to work with. Would definitely recommend their services and will be using them again in the future
Can't say enough about Thor Construction Company. They transformed my backyard space into a perfect little getaway; can't wait to host this summer! They were professional, hardworking bunch and I would recommend you chose this company for your backyard or landscaping needs...big or small!

I had a brief work related project with them and I must say the guys are outstanding. Honest, reliable and straightforward. Highly Recommended!!!
As a custom home builder, we love contracting Thor Construction Company for all of our demolition, excavation and septic work. They are easy to work with, have great equipment and know what they are doing. Our clients are always very happy with them.
Thor Construction Company came in and trenched all new water lines for us when our well line burst. They installed new yard hydrants for us as well. We are so grateful they came in and fixed our water line problem promptly and professionally.
Great work for a great price!!!!

Questions
Straight answers.
How long have you been in business?
Thor Construction is 3 years in business, with 20+ years of experience behind it. One of the two owners runs every job, every day.
What work do you take on?
Septic installs and replacements, excavation and site work, landscaping and hardscaping, shoreline restoration, and full-structure demolition. One crew does all of it with our own machines.
Do you pump septic tanks or do small repairs?
No. We install and replace septic systems. If you only need a tank pumped or a baffle fixed, we will point you to someone who does that work.
Where do you work?
From our base in Bobcaygeon across Kawartha Lakes, Peterborough, Haliburton, Simcoe, Muskoka, Northumberland, Durham and York. Not in Toronto or the core GTA. Find your town on the service areas page, or call and we will tell you straight.
Do you handle permits and locates?
Yes. We file the Ontario Dig Authority locate before every dig, and we prepare and file the permits the job needs: septic, entrance, demolition, conservation authority and Parks Canada.
How fast will I hear back?
An owner calls you back the same business day and books the site visit. You get a written price after it.
Can you work through the winter?
Often, depending on frost depth and access. Frozen ground costs a bit more to dig, which is why fall is the time to get on the schedule.
