Building a house, cottage, shop or addition? You need the lot cleared, the foundation dug to the drawings, the services trenched in and the grade set so water runs away from the house, by a crew that owns its machines.
Excavation jobs go sideways at the handoffs between trades. That's why one Thor crew takes your site from clearing to final grade, and the same crew can put in your septic system and come back to landscape when the house is done.


Every dig starts with a site visit and ends with a clean, graded site. Get it done right the first time with our:



Recent Thor jobs: lot clearing, service trenches and demolition.
Custom home builders hire Thor for demolition, excavation and septic on the same job, because one crew with its own equipment keeps the schedule moving. You get one call, one quote and one crew on site.
We focus on site work for new builds and additions, driveways and entrances, drainage, trenching for water lines and services, lot clearing and demolition excavation.

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.
Hired Thor for complete site services including bringing utilities into my new build and digging for foundation. Once the build was complete they came back and finish landscaped the property and we couldn't be happier. Strongly recommend!
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.
We stand behind every job with a written warranty contract on our workmanship.

Site preparation and foundation digs, lot clearing and grading, trenching and backfill for water lines and services, driveways and entrances, drainage, and the excavation side of demolition and septic jobs.
Yes. Custom home builders hire us for demolition, foundation and services digs, and septic on the same project, so one crew carries the site from clearing to final grade.
Yes. Ontario requires a locate before any digging. We book it through Ontario One Call before the machine arrives, and we do not dig until the marks are down.
We visit the site, look at access, grades and what is under the surface, and give you a written quote for the job.
Often, around Lindsay and along the lakes, where limestone can sit a metre down. We check at the site visit and price it up front rather than surprising you mid-dig.
On a City of Kawartha Lakes road, yes. Any new or changed entrance, including tiling a roadside ditch, needs an Entrance Permit from Public Works Roads. We tell you what your job needs before we start.
We reuse it on site where the grade needs it. Soil that leaves the property goes to a proper reuse or disposal site under Ontario's excess-soil rules.
Yes. New septic systems and full replacements are our core work, so a new build can get its site prep and its septic system from the same crew.
