What Gas Conversion actually costs in Oshawa
Straightforward conversion on a typical Oshawa home runs $1,006 to $1,609. Complex jobs — multi-storey access, heritage masonry, or downtown parking — push the top end toward $2,615. The variance is almost always access, not the work itself.
Line items to look for on a quote
A clean gas conversion quote itemises: labour hours, materials with brand names, dump/haul fees, permits (where required), and a written warranty term. Anything lumped as "misc" or "shop supplies" over 5% is worth questioning.
Why Oshawa pricing differs from neighbouring cities
Oshawa's 70% natural gas mix drives which gas conversion scopes come up most. 6% of the housing stock predates 1960, which is why gas conversion jobs here average slightly more site prep than newer suburbs.
Common questions
How long does gas conversion take in Oshawa?
1 day is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
When's the best time of year for gas conversion in Oshawa?

How much does gas conversion cost in Oshawa?
Most Oshawa jobs land between $1,006 and $1,609. Complex access or heritage masonry can reach $2,615. We quote fixed price after a free on-site scope.
What if it rains or snows on the booking day?
Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
Is gas conversion covered by home insurance in Oshawa?
Sudden damage (storm, animal, appliance failure) is usually covered minus deductible. Gradual wear generally isn't. A written pro assessment before the claim call materially improves outcomes.
What warranty do you offer on gas conversion in Oshawa?
Five-year written workmanship warranty on materials and labour, transferable to a new homeowner within that window. Manufacturer warranties on any installed products pass through separately.
Do you need a permit for gas conversion in Oshawa?
Cleaning and inspection are permit-exempt in Oshawa. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
