Deck Replacement in Calgary — Upgrade to Composite

Your old wood deck served its time. When it starts rotting, warping, or feeling unsafe, the right move is a complete tear-down and rebuild with composite. We handle everything — demolition, disposal, permits, and a new deck that will outlast the next 25–30 years.

Wes and his crew rebuilt our deck while we were recently away on holidays, during which time they had complete access to our house. We returned to find an amazing new deck and the house spotless. Can't say enough about the quality of the work — definitely the A Team!

We hired Serenity Construction to replace our very old cedar deck. The crew arrived on site literally at dawn. They worked fast and efficiently and were finished before 4 pm. The contractor applied for the permit — there were no problems with the inspection.

Common Questions

Deck Replacement FAQs

Get answers to the most common questions about deck replacement in Calgary.

How do I know if my deck needs to be replaced?

If your deck boards are damaged, the structural framing is compromised, or the deck is over 15-20 years old, a full replacement with composite is usually the smartest long-term investment. During our free assessment, we will give you an honest recommendation on the best approach for your situation.

How much does deck replacement cost in Calgary?

Most deck replacement projects in Calgary range from $18,000 to $70,000+ depending on deck size, material choice, and whether footings need to be replaced. That price includes full demolition, disposal, and new composite construction. Your written estimate is your final price — it does not change once work starts.

How long does a deck replacement take?

A typical deck replacement takes 1-3 weeks depending on size, complexity, and permit timelines. Demolition usually takes 1-2 days, and new construction takes 5-15 days. Weather can affect scheduling during Calgary springs and falls.

Do I need a permit to replace my deck in Calgary?

Almost always, yes — even when the new deck matches the old footprint exactly. Calgary treats a replacement as new construction and requires a development or building permit in most cases. This surprises some homeowners, but it is something we manage completely on your behalf. We have done this many times and know what the city requires.

Do you require a deposit for a deck replacement project?

No. Taking a deposit upfront is something we have never done. You pay nothing until the old deck is gone, the new one is built, and you are happy with the result. We take on the financial risk so you do not have to.
