Baseboard installation in Ontario costs $4 to $12 per linear foot installed in 2026, with whole-home trim packages in Kitchener-Waterloo landing between $2,200 and $8,400. Here's the per-linear-foot table by material, what door and window casing add, and how to buy trim work without overpaying.
Baseboard and Trim Cost Per Linear Foot in 2026
Installed pricing — material, labour, fastening, caulking, and ready-for-paint finish — from our trim carpentry team across Waterloo Region:
| Item | Material Grade | Installed (2026) |
|---|---|---|
| Baseboard, 3–4 in. | Primed MDF | $4–$7 / linear ft |
| Baseboard, 5–7 in. | Primed MDF or finger-joint pine | $6–$9 / linear ft |
| Baseboard, any height | FSC solid poplar or oak | $8–$12+ / linear ft |
| Door casing | Per opening, both sides | $95–$220 |
| Window casing with stool and apron | Per window | $110–$260 |
| Old trim removal and disposal | — | $1.20–$2.40 / linear ft |
| Painting after install (two coats) | — | $1.50–$3.50 / linear ft |
Taller profiles cost more in material but barely more in labour — the jump from 3-inch builder base to 5.5-inch modern flat stock is mostly a material delta, which is why upsizing baseboard is one of the cheapest visible upgrades in a renovation.
Whole-Home Trim Budgets
A 1,500–1,800 sq ft home in Kitchener-Waterloo carries roughly 550–700 linear feet of baseboard plus 15–20 door openings and 10–15 windows. At 2026 rates:
- MDF baseboard whole-home: $2,200–$4,900 installed.
- MDF base plus all door and window casings: $4,500–$8,000.
- FSC hardwood package throughout: $6,500–$11,000.
- Add crown moulding in principal rooms: $6–$22 per linear foot on top — our crown moulding cost guide has the full tiers.
What Affects Your Quote
- Corners and layout complexity: trim is priced by the cut as much as the foot — a hallway with eight doorways takes longer than a straight 40-foot great room wall.
- Wall condition: wavy plaster and out-of-square corners in pre-1970 KW homes mean scribing and caulking time that flat new drywall doesn't need.
- Profile matching: matching existing heritage profiles means custom knives at the mill — $150–$400 setup plus higher per-foot stock cost.
- Stairs and skirt boards: the most skill-dense trim in the house; budget separately at $400–$1,200 per staircase.
- Paint scope: factory-primed stock still needs two finish coats — decide whether your painter or the trim crew handles it, and see our trim painting guide for that cost layer.
MDF vs Pine vs Hardwood: Picking the Right Stock
Primed MDF is the 2026 default for painted trim: stable, knot-free, cheapest per foot, and it takes paint beautifully. Its weaknesses are water (it swells at wet locations like bathroom floors) and dents in high-traffic corners. Finger-joint pine costs slightly more and handles moisture better under paint.
Solid poplar and oak make sense where trim gets stained rather than painted, in heritage restorations, and at abuse points — mudrooms, stair skirts, kids' hallways. Style-wise, KW renovations in 2026 run heavily to 5.5–7.5 inch flat-stock modern profiles; our baseboard styles guide walks the look options with photos.
DIY vs Hiring a Pro
Baseboard is among the most approachable finish carpentry for DIYers: a mitre saw, a brad nailer, and patience get you real results in square rooms. Budget a weekend per floor and expect your corners to need caulk. The honest math: DIY saves the $2.50–$4.50 per foot labour component — about $1,500–$2,500 on a whole home — in exchange for 20–30 hours of your time.
Where pros earn their rate: coped inside corners that stay tight through seasonal wood movement, scribing to wavy floors without gaps, stair work, and speed — a two-person trim crew bases an entire main floor in a day. If your project includes crown, casings, or feature wall panelling, one crew doing the whole package beats piecemealing it.
Ways to Save
- Bundle trim with flooring or painting — shared mobilization cuts 15–25% versus standalone visits.
- Go taller in MDF rather than shorter in hardwood for painted looks — the visual upgrade is height, not species.
- Keep casings, replace base: if door casings are sound and current, replacing only baseboard halves the package price.
- Standard profiles from stock: special-order profiles add cost and weeks; most suppliers stock 15+ current profiles.
- Prime-painted supply: factory-primed stock saves a full paint coat of labour on site.
Frequently Asked Questions
How much does baseboard installation cost per linear foot in Ontario in 2026?
Between $4 and $12 per linear foot installed: $4–$7 for 3–4 inch primed MDF, $6–$9 for taller 5–7 inch profiles, and $8–$12+ for FSC solid poplar or oak. Removal of old trim adds $1.20–$2.40 per foot and painting adds $1.50–$3.50 per foot.
How much does it cost to replace baseboards in a whole house?
A 1,500–1,800 sq ft home carries 550–700 linear feet of baseboard, so whole-home replacement runs $2,200–$4,900 in MDF or $6,500–$11,000 in hardwood in 2026. Adding all door and window casings brings a full MDF trim package to $4,500–$8,000.
Should baseboards be installed before or after flooring?
After hard flooring (hardwood, laminate, vinyl plank, tile), so the base sits on the finished floor and covers the expansion gap. With carpet, base is installed first at a set height and the carpet tucks under. Replacing flooring is the ideal moment to replace base — removal rarely leaves old trim reusable.
What size baseboard is standard in 2026?
Builder-grade remains 3–4 inches, but renovations in Kitchener-Waterloo now default to 5.5–7.5 inch flat-stock or simple modern profiles. Taller base costs only marginally more to install since labour is nearly identical — the upgrade is mostly a material cost.
Is MDF or wood baseboard better?
For painted trim, primed MDF wins on price, stability, and paint finish — it's the 2026 standard. Choose finger-joint pine or solid wood at moisture-prone locations, high-impact areas like mudrooms and stairs, and anywhere trim will be stained rather than painted.
