Local crews, local rules.
We renovate Muskoka cottages without erasing what made them feel like a cottage. Additions, full guts, second storeys, and four-season conversions on legacy properties.
In Windermere that work looks specific. Windermere is one of the original Muskoka resort communities, with a tight collection of historic cottages and modern builds along Lake Rosseau and Lake Muskoka.
Practically, it means we scope cottage renovations around Lake Rosseau, Lake Muskoka access, the shoreline setbacks that apply to your lot, and a build window that fits the season. Permits and inspections go through the Township of Muskoka Lakes building department, and we file them as part of the contract rather than leaving the paperwork with you.
Cottage Renovations done properly.
Renovate without losing the cottage
We open layouts, add light, and modernize systems while keeping the timber, stone, and sightlines that made you buy the place. The best compliment we get is 'it feels like it was always this way.'
Three to four-season conversions
Spray-foam re-envelope, slab insulation retrofits, properly sized HVAC, freeze-protected plumbing, and roof load reviews so the cottage you used four weekends a year becomes the home you use 52.
Structural without scars
Beam swaps, foundation lifts, second-storey adds, and load-bearing removals engineered and sealed, then sequenced so the cottage stays weather-tight through every phase.
Live-in or empty, your call
We sequence demo, dust containment, and trade days so weekend-use cottages can stay partially occupied. For full guts, we coordinate around your rental income or family bookings.

"We had an excellent experience with Northern Oaks Contracting. Rob was always friendly, professional and very knowledgeable in many different areas. Not only did he do a great job with our renovation but he noticed and helped us out in some other areas too."
"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."
"The Northern Oaks Contracting crew has been amazing to work with from start to finish. Their ability to keep both customers and trades well-coordinated has made the entire process smooth and stress-free. Highly recommended to anyone looking for a reliable and professional team!"
"Robert installed a kitchen backsplash for us. Communication was great and he showed up to do the work when he said he would. The price was very reasonable and quality of work excellent. Would definitely recommend them."
"We hired Rob to complete a chimney rebuild and do some work on an exterior and interior wall. The work was completed within the agreed upon time frame and when we had an issue with the fireplace after the chimney rebuild Rob was speedy to come back and sort it out."
"My property manager recommended Rob. I obtained multiple quotes, and his company stood out as the most professional and offered the best price. I highly recommend them, excellent customer service and I'm very satisfied with their work."

Cottage Renovations in Windermere questions.
Do you do cottage renovations in Windermere?+
Yes. Windermere is inside our regular service area and we run cottage renovations projects on Lake Rosseau and Lake Muskoka through the season. We are based in Muskoka, so site visits, warranty callbacks, and supplier runs do not carry travel surcharges from out of district.
Do I need a permit for cottage renovations in Windermere?+
Structural work, additions, most decks, shoreline structures, and new plumbing or electrical need a permit from the Township of Muskoka Lakes building department. Cosmetic finishes usually do not. We confirm the requirement during the site visit and handle the application, drawings, and inspection scheduling under the same contract.
Can we still use the cottage on weekends while the reno is underway?+
Sometimes, depending on scope. We sequence work so kitchens or main living areas stay usable when possible.
How do I get a price for cottage renovations in Windermere?+
Send us the project details and we book a site walk in Windermere, take measurements and photos, then send a fixed-price written proposal with the scope, allowances, and payment schedule laid out line by line. There is no charge for the visit or the quote.
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.
