"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."

Start your project

Ready to start your Retaining Walls project?

Tell us about the space. A real project manager replies within 4 to 8 hours with next steps.

How we approach it

How we approach every project.

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.

01

We understand the space first

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.

02

We choose materials with the end in mind

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.

03

We build it properly, not just quickly

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.

04

We finish what we start

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.

5yr
Workmanship warranty

All workmanship backed by a 5-year warranty in writing.

What's involved

Every trade in a retaining walls project.

We run the full scope or with vetted partners on a single contract. Here's what typically lands inside this kind of project.

Engineering

Stamped designs for any wall over 1.2 m with drainage and geogrid spec.

Excavation

Cut, fill, and base preparation with compacted granular A.

Drainage

Perforated weeping tile and free-draining backfill behind every wall.

Block or stone

Armour stone, segmental block, or natural stone face options.

Steps & landings

Integrated steps, terraces, and pathway tie-ins.

How we meet

On site, or on video.

Two ways to kick things off. Whichever is easier for you.

On-site walk-through

We'll meet you at the property, pull tape, take photos, and walk the scope with you in person.

Live video walkthrough

Prefer to stay put? Hop on a video call and we'll walk the space or the plans together from anywhere.

FAQ

Common questions.

Do shoreline walls need MNRF approval?+

Any work below the high water mark almost always requires MNRF and municipal approval. We handle the application.

Armour stone, segmental block, or poured concrete?+

Armour stone reads most natural and ages best. Segmental block is faster on small terraces. Poured concrete is for engineered walls above 6 feet or with heavy surcharges.

How tall can a retaining wall go?+

Up to about 3 feet without engineering. Above that, sealed structural drawings are required. We've built engineered armour stone walls to 8 feet.

Will the wall heave in winter?+

Properly built walls don't. Frost-depth base, free-draining backfill, and drainage tied to grade is what stops heave. Heave is always a base or drainage failure.

How long does a wall project take?+

Most residential walls run 2 to 6 weeks on site. Shoreline walls with permits add 3 to 6 months upfront.

Can you terrace a steep cottage lot?+

Yes. Stepped terraces with armour stone or boulder walls create usable level ground on steep shield-rock lots without changing the drainage pattern.

Do you handle the MNRF and DFO applications?+

Yes. We prepare and submit, attend any agency meetings, and coordinate the in-water work window.

What's the difference between dry-stack and mortared walls?+

Dry-stack uses no mortar, drains naturally, and reads traditional. Mortared walls are sealed, used where appearance demands tight joints, and require engineered drainage behind.

Can you tie stone steps into the wall?+

Yes. Hand-set granite or fieldstone steps integrated with the wall, with code-compliant rise and run.

How does the first meeting actually work?+

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.

Do you source materials locally?+

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.

Who is actually on site during the project?+

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.

How do you keep us in the loop while work is happening?+

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.

What happens if something needs to change mid-project?+

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.

Do you clean up as you go?+

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.

What kind of warranty comes with the work?+

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.
