"I hired Northern Oaks for a driveway extension as part of my home renovation so I could park two additional cars, and I'm really impressed with the results. The quality of the work and craftsmanship really stand out. It's been over 6 months and it's held up perfectly."

FAQ

Windermere questions.

Do you work on Windermere's older lakefront estates?+

Yes. Windermere has some of the oldest continuously owned cottages on Lake Rosseau, and much of our work here is careful renovation and addition work on properties that have been in the same family for generations.

Who issues permits for Windermere projects?+

The Township of Muskoka Lakes building department, with district and shoreline review where the work sits near the water.

Can you match original millwork and detailing?+

We do it regularly: matching trim profiles, board widths, and stain colours so an addition reads as original rather than bolted on.

Do you build boathouse-area stonework and stairs?+

Yes. Stone stairs down to the water, landings, retaining walls, and terraces built for the freeze-thaw cycle rather than for a photo in year one.

How disruptive is a renovation during cottage season?+

Where possible we schedule the noisy structural phase for the off-season and keep summer work to interior finishing. If the family will be on site we agree quiet hours and access routes before we start.

Are you insured and WSIB covered?+

Fully insured with WSIB coverage in good standing, and we can provide current certificates before work begins.
