Innisfil stretches from lakefront Alcona and Friday Harbour to village streets in Stroud, Lefroy and Cookstown. Newer builds bring dry, open basements ready for finishing, while lakeside and older properties reward moisture-first construction.
Cottage-country lifestyle with commuter convenience means Innisfil basements become guest suites, rec rooms and rental units. Whatever you start with, you end with finished square footage your family uses every week, and a number your Innisfil house carries at resale.

We have not published an Innisfil project yet, so here is a recent one from Bradford, built to the same specification and warranty we bring to Innisfil.
Two bedrooms, a bathroom with a custom tiled shower, and a laundry room with washer plumbing and a sink. A slat feature wall with integrated LED, soundproofing, seven solid-core doors, window casings, 62 pot lights and a heat-pipe relocation, on an insulated DRICORE R+ subfloor. Built in two sections, which added about a week and a half.

Every basement is priced from the same quote sheet, line by line: a 1,000 sq ft basement with a three-piece bathroom comes to about $67,800 before HST, and the price per square foot falls as the basement grows because the permit, bin, breakers, stairs and bathroom cost the same at any size.
