Local crews, local rules.
On a Muskoka lakefront the deck is the most-used room of the house. We engineer multi-level cedar and composite decks for shoreline grade, ice loading, and decades of barefoot use.
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 decks & outdoor living 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.
Decks & Outdoor Living done properly.
Engineered for the lot
Helical piers, pinned footings, or stepped sonotubes chosen for the actual rock and grade under your deck. Shoreline decks get ice-load reviews. Multi-level decks get engineered beam sizing.
Material chosen for use
Western red cedar for cottage tradition and patina. Composite (Trex, TimberTech) for zero-maintenance entertaining decks. Ipe and other hardwoods for premium long-life builds.
Built for the view
Glass and cable railings, hidden fasteners, low-profile rim joists, and inset lighting designed to keep sightlines open from cocktail height to standing height.
All-day outdoor rooms
Sun-path studies, integrated planters, built-in seating, hot tub framing, and shade structure tie-ins so the deck is a real room, not just a platform between the cottage and the lake.

"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!"

Decks & Outdoor Living in Gravenhurst questions.
Do you do decks & outdoor living in Gravenhurst?+
Yes. Gravenhurst is inside our regular service area and we run decks & outdoor living 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 decks & outdoor living 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.
Cedar or composite decking for a cottage, which is the better call?+
Composite if you want zero maintenance, cedar if you want the smell and the patina. Both are fine in Muskoka with the right detailing.
How do I get a price for decks & outdoor living 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.
