Named #1 by the Quality Business Awards for craftsmanship, transparency, and on-time delivery across Muskoka.
"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!"
"Rob did a full renovation at my cottage. He listened carefully to my vision and worked closely with me to bring it to life. He was fair with his pricing and friendly to work with. I recommend Rob for your renovation project!"
"Rob was amazing to work with. His diligence and hard work really transformed our home into more than we ever expected. It was a pleasure working with Rob, always went above and beyond."
"Amazing experience! We worked with Rob, who was friendly, respectful and knowledgeable from start to finish. Part-way through overhauling our powder room he identified some issues that no one could have foreseen, but offered to come back and make it right."










Tell us about the space. A real project manager replies within 4 to 8 hours with next steps.
Four things we do on every job, no matter the size. It's how we make sure the finished work still looks and functions the way it should years down the road.
Before we quote or design anything, we walk the site, take real measurements, and ask what you actually want out of the space. The best projects start with a clear picture, not a guess.
Every material gets picked for how it'll look, feel, and hold up over years of real use. We'll tell you where to spend and where you can save without regretting it later.
Straight walls, tight joints, level floors, clean finishes. We take the extra hour it costs to do it right because it saves you the callback and it's the work we want our name on.
One project manager from first quote to final walk-through. Punch lists get closed, the site gets cleaned, and you get a warranty in writing. No loose ends.
All workmanship backed by a 5-year warranty in writing.








No mystery, no ghosting between steps. Here's the exact path from first phone call to final walk-through, with what happens, who's on it, and what you'll have in your hands at the end of each stage.
Site walk, setback review, septic and shoreline assessment before drawings.
We coordinate the architect or work to your drawings, with weekly value-engineering check-ins.
Building, septic, MNRF shoreline, and any committee of adjustment work handled by us.
Dedicated project manager on site daily, weekly photo logs, fixed-price draws.
Same project manager from first call to final walk-through.
We run the full scope or with vetted partners on a single contract. Here's what typically lands inside this kind of project.
Clearing, blasting, helical piles, and engineered fill for Canadian Shield lots.
Conventional or timber framing, sheathing, WRB, and high-performance insulation.
Standing seam metal, architectural shingle, and cedar shake systems.
Full PEX manifold systems, well/septic tie-ins, and freeze-protected runs.
Panel sizing, generator transfer, EV charging, and low-voltage rough-in.
Heat pumps, in-floor hydronics, ERV/HRV ventilation for four-season comfort.
Stone fireplaces, chimneys, and exterior veneer by our masons.
Cabinetry, tile, millwork, paint, and finish carpentry to a single standard.
Driveways, retaining walls, grading, and landscape tie-in at handover.
Two ways to kick things off. Whichever is easier for you.
We'll meet you at the property, pull tape, take photos, and walk the scope with you in person.

Schedule a callMost 3,000 to 5,000 sq ft lakefront builds run 14 to 20 months from permit issuance, factoring in winter shutdowns and barge logistics.
Yes. We frame and close in through winter, then move to interior finishing during the coldest months.
Always. We tender, value-engineer, and build to any sealed drawing set.
Either. We have design partners we work with daily, or we tender competitively against your chosen architect's drawings.
We pull every permit in our name: building, septic, MNRF shoreline, and any committee of adjustment work. You sign one owner-authorization form, we manage the rest.
Yes. We barge materials, equipment, and crews into water-access sites across Lake Joseph, Lake Rosseau, and Georgian Bay every season.
Two-year full workmanship warranty on everything we build, plus the Tarion-equivalent structural warranty on new builds. Maintenance schedule handed over at closeout.
Yes. We routinely build a main cottage now and a bunkie or boathouse in a later phase, sequenced so the second phase does not disturb the first.
As much or as little as you want. Most of our clients live in Toronto or out of province. We send weekly photo logs, host video walkthroughs, and meet in the city between site days.
We come to the site (or hop on a video call, whichever is easier), walk through the space with you, take measurements and photos, and ask questions about how you actually use the property. There is no sales pitch. You leave the meeting with a clear next-step plan and a rough sense of scope and timing, and we leave with enough information to start putting a real proposal together.
Local sourcing is absolutely an option and something we lean into whenever it makes sense, but it is not the only path. We source based on each client's needs, budget, and the specific goals for their project. Sometimes the right material is a local Muskoka supplier or a nearby millwork shop. Other times it's a specialty product from further away that better fits the look, performance, or lead time. We walk you through the options and make the call together.
A dedicated project manager owns your file from the first conversation through the final walk-through. On the ground you'll see our own carpenters and site lead running the day-to-day, plus vetted trade partners for plumbing, electrical, HVAC, and specialty finishes. Everyone on site works to the same standard and reports up through the project manager, so you always know who to call and never get bounced between subs.
You get a single project manager as your point of contact, weekly photo updates so you can see progress even if you're out of town, scheduled check-in calls at major milestones, and any change to scope, timeline, or materials in writing before it happens. Most of our clients live in Toronto or out of province, so the whole process is built to work without you needing to be on site.
Change orders happen on almost every project once things are open and real conditions are visible. When something needs to shift (a hidden condition, a design tweak you want, a material swap) we document exactly what's changing, the impact on schedule, and the impact on the number, then send it to you for sign-off before any work happens. No surprises on the final invoice.
Every day. Site gets broomed and organized at the end of every workday, materials get stored properly, and containment stays in place so dust doesn't migrate through the rest of the house. At the end of the project the site gets a full detail clean before handover, and we do a joint walk-through with you to catch anything that needs a final touch.
Real projects, real progress shots. Tap through for the full story on any of them.

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.
