7 Costly Mistakes Ottawa Homeowners Make When Building a Deck

Building a deck is a major investment. Unfortunately, many homeowners make decisions that lead to costly repairs, safety issues, or disappointing results.

Here are the seven most common deck mistakes we see in Ottawa.

1. Hiring the Cheapest Contractor

The lowest price often comes with hidden risks.

Many companies subcontract most of the work, which can create problems when issues arise later.

Choosing an experienced builder ensures the team responsible for construction is accountable for the finished product.

2. Ignoring Permit Requirements

Many decks require city permits and inspections.

If the permit process is ignored, homeowners may face:

• fines
• construction delays
• forced structural corrections

Professional deck builders understand local building codes and manage this process properly.

3. Underbuilding the Structure

A deck may look beautiful on the surface, but the real strength lies in the foundation and framing underneath.

Common structural shortcuts include:

• undersized beams
• insufficient footings
• improper ledger attachments

These mistakes can lead to sagging or unsafe decks.

4. Choosing the Wrong Materials

Not all decking products perform the same.

Cheaper materials may fade, stain, or deteriorate quickly. Investing in quality materials ensures the deck maintains its appearance and structural integrity for years.

5. Poor Drainage Planning

Water management is often overlooked during design.

Without proper drainage, decks can experience:

• moisture damage
• rot
• mold growth

Proper spacing and structural design help prevent these issues.

6. Weak Railings

Railings are a major safety feature.

They must meet strict height and strength requirements to pass inspection.

Using approved railing systems ensures compliance and safety.

7. Not Planning for Long-Term Use

Many homeowners design decks based only on immediate needs.

A well-designed deck considers future use, including:

• entertaining space
• outdoor dining areas
• shade structures
• privacy features

Proper planning creates a deck that remains functional for decades.
