Excavation and Site Services
M. Riddle Excavating is a family-run excavation and septic contractor based in Kingston, Ontario, with more than 20 years in the trade. We design and install septic systems, dig basements, put in water and sewer lines, clear land, build roads and driveways, and handle grading and drainage, and our Riddle Aggregates yard supplies topsoil, sand and gravel. We work across Kingston, Greater Napanee, Frontenac County, Bath and Loyalist Township, Gananoque, Rideau Lakes and Prince Edward County.
Septic System Design and Installation
We design, install, repair and replace septic systems for new homes and for properties with a failing tank or bed. The work covers excavation, tank placement, the bed and final grading, built to the Ontario Building Code. See our septic system services.
Basement Excavation
We dig basements and foundations for new homes, additions and structural work, from layout to safe digging, spoil removal and final grade. See our basement excavation services.
Water and Sewer Line Installation and Repair
We install, repair and replace water and sewer lines, from trenching and new pipe to connections and backfill. We can also coordinate the work with a septic installation on the same property. See our water and sewer line services.
Land Clearing
We remove trees, brush, stumps, rocks and debris to get a lot ready for a new build, a driveway or a septic system, then carry on with the excavation and grading. See our land clearing services.
Road Work and Driveways
We build and repair gravel driveways and private access roads, and handle the ditches, culverts and grading that keep them draining. See our road work services.
Grading and Drainage
We install French drains and weeping tile, regrade lots so water runs away from the house, and fix wet yards with drainage pipe and ditching. See our grading and drainage services.
Topsoil, Sand and Gravel
Our yard, Riddle Aggregates, is at 1780 Washburn Road in Inverary and sells screened topsoil, sand and gravel for pickup or delivery. It is open Monday to Saturday. See topsoil and gravel.
