Renovation Contractor in Oshawa & Durham Region
Uxbridge is different from the rest of Durham Region in one specific way: a lot of properties here run on private septic systems, not municipal sewer. That changes what your addition can support before we ever discuss layout.
Uxbridge at a Glance
Before We Design Anything
Uxbridge's rural character means bigger lots, wider setback variances, and — for a real share of properties — private septic and well systems instead of municipal services. We check all of this before we design anything.
Adding a bathroom or a bedroom that increases occupant load means checking your septic system's capacity as part of the initial assessment — a plan that works fine on municipal sewer can be the wrong plan entirely for a septic property.
Building Up
Adding a full floor on top of your existing home isn't just framing walls — it changes the structure underneath it too.
How It Works
An addition isn't just built — it's checked against your zoning, your septic capacity where relevant, engineered, permitted, and inspected. We carry all of it.
We check your setbacks, septic capacity if applicable, and whether LSRCA or TRCA approval is needed before we design.
Scaled plans plus structural engineering where required — mandatory for any second-storey work.
Filed through Cloudpermit. We coordinate any required Health Department or conservation authority approvals alongside it.
Framing, structural, electrical, and plumbing inspections through to final sign-off.
Our on-time guarantee. If we miss the agreed completion date for reasons within our control, you're compensated $300 for every day past it — part of the Certainty Stack on every Cornerstone build.
Why Build It Permitted
A permitted addition shows clean on a title search. An unpermitted one can hold up your sale or force disclosure to buyers.
Unpermitted structural work can void your coverage if something goes wrong down the line — permitted work protects your policy.
The Township can order unpermitted additions removed or brought up to code after the fact. Done right the first time, that risk doesn't exist.
Proper engineering means your addition holds up for decades — not just long enough to pass a first inspection.
