From swapping a single fixture to a full rough-in, our licensed plumbing partners handle the water and drain side of every patios & interlock project. Permits, inspections, and warranty all live under our contract, so you're not chasing separate trades.
Rough-in done right the first time
Water supply, drains, and venting get laid out before drywall or tile ever goes up. We size lines for real flow, protect pipes from freezing on exterior walls, and leave clean shut-offs where you can actually reach them.
Fixtures, repairs, and small jobs too
Not every job needs a full rebuild. We'll swap a toilet, replace a leaky valve, run a new line for an ice maker, or track down the source of a slow drain, and give you a fixed quote before we start.
Materials and sourcing
We spec materials for how they hold up on a Muskoka property first, and how they look second. That means marine-grade fasteners near the lake, kiln-dried framing where humidity swings, and finishes rated for the freeze-thaw cycle. Where it makes sense we source through Huntsville, Bracebridge, and Port Carling suppliers so lead times stay short and warranty is easy to honour.
Timeline and scheduling
Most patios & interlock plumbing scopes are planned around cottage season, weather windows, and access. We book a real start date once the quote is signed and the materials are secured, share a week-by-week schedule, and give you honest updates if anything shifts. No surprise gaps, no crews disappearing for other jobs.
Permits, inspections, and code
Any patios & interlock plumbing work that needs a building, ESA, or shoreline permit gets pulled in our name, tracked on our schedule, and closed out with the final inspection before we invoice the last bill. We flag anything code-triggered early so you can decide with all the information, not after drywall is up.

Ready to start your patios & interlock plumbing project?
Fixed-price proposals, one project manager, and a Muskoka crew that shows up.
A clear path for patios & interlock plumbing.
The details change by property, but the way we run the work stays consistent: understand the space, choose the right materials, build it properly, and close every loose end.
Understand the space
We walk the property, review access, measure the area, and learn how you want the patios & interlock plumbing work to function when it is finished.
Choose the right materials
We compare durability, look, maintenance, lead time, and local sourcing options so the choices fit the end goal, not just a showroom sample.
Coordinate the trades
Carpentry, masonry, tile, plumbing, electrical, drainage, and inspections are scheduled under one project manager when the scope needs them.
Finish and stand behind it
We close the punch list, clean the site, hand over care notes, and put the workmanship warranty in writing.
"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."
