Why Baseboards & Trims Stands Out

Baseboards and Trim for Mississauga, Toronto and Barrie

A floor is only finished when the trim is on. Baseboards cover the expansion gap at the wall, casings frame doors and windows, shoe moulding and quarter round close the gap when the old baseboards stay, and crown moulding finishes the line at the ceiling.

What we carry

All of our trim is primed MDF: smooth, straight and ready for paint.

  • Baseboards: step bevel, colonial, two step, flat stock and modern edge bevel, from 4 to 7 1/4 inches tall.
  • Door and window casings: bevel step, two steps, colonial, flat stock and modern edge, plus thicker back bend casings.
  • Shoe moulding: primed MDF shoe mould for the floor line, listed as door stop (shoe moulding).
  • Quarter round: 5/8 x 5/8 inch.
  • Crown moulding: Georgian, Milan and Tuscan profiles in 12 ft lengths.

Matching trim to the floor

  • New baseboards or keep the old ones? If the old baseboards come off with the old floor, new baseboards cover the gap. If they stay, add shoe moulding or quarter round.
  • Shoe moulding or quarter round? Shoe moulding is taller and thinner for a slimmer line; quarter round is a true quarter circle and covers a slightly wider gap.
  • Keep one style: use the same profile family on baseboards and casings, such as step bevel with bevel step casing.
  • Tile floors: in wet areas, use matching tile trim such as cove base, and primed MDF baseboards in the dry rooms next to them.

Why primed MDF

Primed MDF is smooth, consistent and dimensionally stable, so it paints cleanly and does not shrink away from the wall in winter the way solid wood can. Prime cut ends, caulk joints and keep it out of areas that stay wet.

Installed with the floor

Our own crews install trim as part of the flooring job. Bring room measurements to our Mississauga store on Dundas St E or our Barrie store on Saunders Rd, and we will count the trim with the floor order.

Still Have Questions?

Quick answers to the questions homeowners ask most before buying.

What trim do you carry?
Primed MDF baseboards, door and window casings, crown moulding, shoe moulding, door stop and quarter round, in matching profiles.
Do I need new baseboards when I replace a floor?
Not always. If the existing baseboards stay, shoe moulding or quarter round covers the expansion gap.
How do I match casings to baseboards?
Use the same profile family, such as step bevel with bevel step casing, with the casing slightly thicker than the baseboard.
Is your trim pre-painted?
It is primed MDF, ready for paint.
Can I buy trim with my floor?
Yes. Bring room measurements and we will count trim lengths with the floor order at either store.
