Full gut renos, additions, and tasteful modernizations of legacy cottages.
Huntsville is the practical base for cottage work across northern Muskoka. The Peninsula Lake and Fairy Lake chain runs right through town, Mary Lake is fifteen minutes south, Lake of Bays is a short run east through Dwight, and the Hidden Valley slope sits between them. Being based here means our crews are on site early rather than burning the first hour of the day driving.
Cottage renovations in this area are governed less by finish selection and more by three constraints: the season, the shoreline, and the building's original construction. A lot of the housing stock around these lakes started as a three-season building on piers and got insulated and added to over decades, so the first thing we do on any cottage renovation here is establish what is actually holding the building up and how it is drying.
Shoreline setbacks, the shoreline road allowance where it applies, and any work within the regulated area put your project in front of the Town of Huntsville building department and, depending on the lot, the District of Muskoka. That review is not an obstacle, but it is a schedule item, and pretending it is not is how projects miss a season. We file the applications and manage the inspection calendar as part of the contract.
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.'
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.
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.
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."

Yes. We either bring in temporary heat and hoarding to keep the work area above freezing, or we schedule the project into the shoulder seasons. What we will not do is install finishes, tile, or cabinetry in a building that will swing forty degrees before it is closed in. Which approach applies depends on your specific building, and we will tell you which one during the site visit.
It depends almost entirely on the foundation and the mechanical systems, not on the finishes. Insulating and air-sealing the envelope, protecting the plumbing, adding a heat source, and dealing with a pier foundation that was never designed for frost are the real cost drivers. We scope it after an inspection rather than quoting a number sight unseen, because two cottages on the same bay can differ by six figures.
Renovating inside the existing footprint is generally straightforward. Extending toward the water, adding a storey, or rebuilding a non-conforming structure is where setbacks matter, and older cottages on these lakes are frequently non-conforming because they were built before the current rules. That does not mean you cannot proceed, it means the path may run through minor variance rather than a straight permit. We identify which one applies before you commit to a design.
Yes. Water access changes logistics and cost, not feasibility. Materials get barged, the crew schedule gets built around the crossing, and we stage deliveries so we are not making four trips for one job. We price barge and staging as an explicit line in the estimate rather than burying it.
Design and permitting in the fall, construction starting late winter or early spring, if you want the cottage back for the season. Waiting until May to start planning a summer renovation on a Huntsville lake means you are competing for the same trades and the same permit queue as everyone else who waited.
That is most of our cottage work. You get photo updates and a written progress log through the client portal, we handle deliveries, inspections, and trade coordination on site, and we do a walkthrough by video if you cannot be here. Being based in Huntsville is the reason that works.
Year-round. Huntsville has a strong four-season community, and we run interior renovations and new-build framing through the winter with the right protection in place. Only certain exterior masonry and concrete pours get seasonal scheduling.
Peninsula Lake, Fairy Lake, Mary Lake, Vernon Lake, and the north end of Lake of Bays, including properties out toward Hidden Valley and the Algonquin Park corridor.

Walk the site with us. We follow up with a fixed-price proposal, usually within two weeks.

The Huntsville lake chain has its own rules. Setbacks, septic capacity, winter access, and a short build season decide what is possible before design ever starts.
