Questions, answered.

Straight answers to what Ottawa homeowners ask us most. Still wondering about something? Call or text 613-806-4000.

All questions
How much does a deck cost in Ottawa?

Most new decks we build in Ottawa land between about $40 and $120 per square foot installed, depending on material, height, railings and site conditions. A typical 300 sq ft composite deck is roughly $19,500 to $30,000. Use our estimator for a ballpark, then call or text for an exact, itemized quote within 24 hours.

Do I need a permit to build a deck in Ottawa?

Often, yes. The City of Ottawa generally requires a building permit for decks more than 60 cm (about 2 ft) above the ground, and some covered or attached decks need one regardless of height. We confirm the requirements for your property and handle the drawings and permit application for you.

How long does it take to build a deck?

Most residential decks take 3 to 7 working days on site once materials arrive. Larger multi-level decks, covered decks and pergolas can take two weeks or more. Permit timing is separate, and we give you a realistic schedule with your quote.

Composite, PVC or wood: which is best for Ottawa winters?

Pressure-treated wood and cedar cost the least up front but need staining every few years. Composite and PVC cost more but won't rot, splinter or need staining, and they handle freeze-thaw cycles and snow well. We walk you through swatches and the long-term cost of each.

Can you repair or replace my existing deck?

Yes. We repair rotted boards, stairs and railings, and we can re-deck over a sound frame. If the structure has reached the end of its life, we tear it out, haul it away and build new, and we tell you honestly which option makes sense.

Do you offer a warranty?

Yes. Every deck comes with a written 5-year workmanship warranty, on top of the manufacturer's warranty on composite and PVC boards, which is often 25 years or more.

Are you insured?

Yes. Ryan's carries full liability insurance and WSIB coverage, and we're happy to provide certificates before any work starts.

Which areas do you serve?

We build decks across Ottawa, including Stittsville, Kanata, Carp, Richmond, Riverside South, Manotick, Greely, Barrhaven, Orleans and Findlay Creek. Not on the list? Call or text and ask.
