Basement floor leveling in Whitby
Whether it is a 1970s bungalow near downtown or a newer build in Taunton North, most Whitby basements have the same problem: a slab that slopes toward the drain and dips in the corners. Basement floor leveling in Whitby is our most requested job — we grind the high spots, patch cracks and pour self-leveling concrete so your LVP, laminate or engineered hardwood goes down flat.
Leveling a Whitby basement floor before the framing goes up gives the framers, drywallers and flooring installer one flat datum — ±2 mm over 3 m — which matters most for rental suites and family rooms getting LVP, laminate or engineered hardwood.
Garage floor grinding & driveway concrete repair in Whitby
Garage floor grinding in Whitby opens up the slab so an epoxy or polyaspartic coating actually bonds. We also handle driveway concrete repair in Whitby — broken edges, spalls and cracked aprons rebuilt with exterior-rated mortars before winter freeze-thaw makes them worse. See concrete grinding and concrete patching & repair.
Concrete patching contractors in Whitby
MIR is a local concrete patching contractor in Whitby, repairing cracked garage floors, spalled steps, broken slab edges and damaged basement floors, then grinding the repairs flush so nothing shows under new flooring. For heavier damage we chip out unsound concrete first.
Condo boards and property managers in Whitby can also call us for common-area floors, parking garages and trip-hazard removal — see commercial & condo work.

Whitby questions.
No. We measure your slab on site with a rotary laser and give you a fixed-price quote — free, with no obligation.
No. Mudjacking (concrete lifting) pumps material under a sunken exterior slab to raise it. Floor leveling flattens the surface of an interior slab with grinding and self-leveling concrete. MIR does floor leveling, grinding and repair — not slab lifting.
Yes — Brooklin and north Whitby are part of our home area, along with every neighbourhood south to the lake.
Yes. We set the finished datum so the room is flat while keeping water able to reach the drain, and we form around the drain before the pour.
