Local crews, local rules.
Boathouses and docks are the most regulated structures on the lake. We design, permit, and build single and two-storey boathouses, crib docks, and floating docks across Muskoka.
In Gravenhurst that work looks specific. Gravenhurst is the south gateway to Muskoka and one of the busiest lakefront markets in the district. We renovate older cottages and build new from Sparrow Lake up to Lake Muskoka.
Practically, it means we scope boathouses & docks around Lake Muskoka, Gull Lake, Kahshe Lake access, the shoreline setbacks that apply to your lot, and a build window that fits the season. Permits and inspections go through the Town of Gravenhurst building department, and we file them as part of the contract rather than leaving the paperwork with you.
Boathouses & Docks done properly.
Permit-first
Boathouses live or die at the application stage. We start every project with a footprint review, zoning check, and MNRF/DFO assessment before any design work begins.
Crib, pile, or floating
Crib docks for permanence on protected lakes. Pile docks for faster install and lower lake-bed impact. Floating docks for severe ice or shifting water levels. Each chosen for the specific lake and bottom.
Marine logistics
Barge staging, in-water work windows, marine concrete pours, and coordinated lift, boat, and slip installs. We've worked every Muskoka lake and most of Georgian Bay.
Upper-level living
Two-storey boathouse second levels finished to cottage standards: insulated, plumbed, wired for full-service guest accommodation where zoning permits.

"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."

Boathouses & Docks in Gravenhurst questions.
Do you do boathouses & docks in Gravenhurst?+
Yes. Gravenhurst is inside our regular service area and we run boathouses & docks projects on Lake Muskoka and Gull Lake through the season. We are based in Muskoka, so site visits, warranty callbacks, and supplier runs do not carry travel surcharges from out of district.
Do I need a permit for boathouses & docks in Gravenhurst?+
Structural work, additions, most decks, shoreline structures, and new plumbing or electrical need a permit from the Town of Gravenhurst building department. Cosmetic finishes usually do not. We confirm the requirement during the site visit and handle the application, drawings, and inspection scheduling under the same contract.
Can I still build a new boathouse in Muskoka?+
Often, yes, but rules vary by lake and township. Most builds are replacements or expansions of existing footprints.
How do I get a price for boathouses & docks in Gravenhurst?+
Send us the project details and we book a site walk in Gravenhurst, take measurements and photos, then send a fixed-price written proposal with the scope, allowances, and payment schedule laid out line by line. There is no charge for the visit or the quote.
Do you renovate older Gravenhurst cottages?+
Constantly. Many Gravenhurst properties are 1950s to 1980s builds where the structure is sound but the systems, insulation, and layout are dated. We handle everything from selective updates to full gut renovations with structural changes.
Which areas around Gravenhurst do you cover?+
Lake Muskoka's south shore, Gull Lake, Kahshe Lake, Sparrow Lake, and the surrounding rural roads down toward the Severn.
