Patios are where the Muskoka summer happens. We build natural-stone and precast interlock patios with seat walls, fire pits, and drainage tied into existing grade, engineered for shield rock and freeze-thaw.
Every specialty within patios & interlock, with its own scope, timeline, and fixed-price proposal. Pick the one that matches your project.

Named #1 by the Quality Business Awards for craftsmanship, transparency, and on-time delivery across Muskoka.
"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."
"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."
"We contacted Northern Oaks Contracting because of the skills listed on their webpage covered what we were looking for to build a stone fireplace from beginning to end. We didn't want to hire one company for framing and another for the masonry, and they handled it all."
"Rob did a great job repairing my chimney. He was very prompt to reply and come out to assess our job. His price was fair, he communicated clearly and promptly, showed up on time and completed the job within the timeframe that was agreed on."
"We hired Rob to install a new front porch and repair a set of stone steps leading into our garage. We are extremely happy with how the completed project looks and with the work Rob did for us. Rob was flexible and accommodating."
"Northern Oaks Contracting is a company dedicated to performing a quality product at a fair price. Rob is a knowledgeable individual who is professional, caring and a pleasure to work with. I highly recommend this company for any home repairs including stone work."










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.
Sun, view, and circulation study before footprint is locked. Sample panel on site.
Excavation, geotextile, crushed stone, and proper compaction. The part nobody sees, but it's everything.
Hand-cut flagstone or precast interlock set tight, with seat walls and fire-pit features.
Polymeric sand, sealer (optional), and a clean handover walkthrough.
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.
Excavation, geotextile, and compacted aggregate base for zero settlement.
Interlock, natural flagstone, or porcelain pavers laid to pattern.
Aluminum or concrete edge restraints with polymeric sand joints.
Integrated steps, seat walls, and fire-pit features.
Surface slope, channel drains, and tie-ins to keep water moving.
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 callFlagstone reads more cottage and more permanent. Interlock is faster, more uniform, and easier to repair. We build both, often together.
Properly compacted crushed-stone base, geotextile under the base, and drainage tied to grade. Heave is a base problem, not a stone problem.
Most patios run 2 to 5 weeks on site depending on size, features, and base requirements.
Both. Stone wood-burning rings and engineered gas fire features with stainless burners. Gas requires a licensed line install.
Yes. Integrated seat walls in natural stone or precast, often combined with fire pits to create a defined outdoor room.
Polymeric sand is mandatory. Surface sealer is optional, primarily for color enhancement and stain resistance on light-colored stone.
Yes. Transition heights, drainage, and grade tie-ins are designed before any excavation.
No, if built right. Pinned edges, properly drained base, and stone-on-stone bedding handle shield-rock sites without movement.
Polymeric sand instead of regular jointing sand. It hardens with water and resists weed and ant intrusion for years.
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.
A full two-year workmanship warranty on everything we build, in writing, handed to you at closeout along with a maintenance schedule and a folder of all product manuals, paint colours, and finish specs. If something isn't right we come back and fix it, no debate. On new builds you also get the applicable structural warranty coverage on top of that.
