WHY WE BUILD DECKS DIFFERENTLY

Founded by trim carpenters who tired of watching poorly-built decks fail, we
invested decades learning the building science of outdoor structures:

WHAT WE LEARNED FROM FAILURES:
→ Why deck ledgers separate from houses (most common failure)
→ How freeze-thaw cycles destroy standard fasteners
→ Why bounce in deck floors leads to structural failure
→ How moisture penetrates “waterproof” coatings
→ Why building code minimums still result in 10-15 year lifespans

WHAT WE DEVELOPED:
✓ Fastener specifications that last 30+ years in Canadian climate
✓ Ledger attachment methods that exceed code requirements
✓ Joist sizing based on long-term deflection, not just code minimums
✓ Drainage systems that prevent moisture accumulation
✓ Finish schedules that actually protect wood

THE VALUE OF BETTER BUILT DECKS:
When you build once and build properly, you avoid rebuild costs, maintenance
headaches, property value loss, and safety risks. Our details cost 15-20% more
upfront but eliminate future problems.

The DesignersDecks Difference –Attention To Detail

Our Deck Builders sweat the little things…

ATTENTION TO DETAIL OTHERS MISS

Our deck builders sweat the little things because we’re trim carpenters by training:

✓ GLASS RAILING SYSTEMS: We install them plumb (most contractors don’t)
✓ COMPOSITE DECKING: We understand expansion coefficients (temperature movement)
✓ STAIR ENGINEERING: Uniform rise/run that passes the “coffee cup test”
✓ LIGHTING INTEGRATION: Low-voltage systems done right the first time
✓ WATERPROOFING: Second & third-story deck membrane systems

WHAT THIS MEANS:
→ No callbacks for wavy railings
→ No gaps in composite decking from thermal expansion
→ No uneven stairs that spill drinks
→ No lighting failures from poor wire connections
→ No leaks damaging spaces below decks

Designers Decks are Deck Design and Building Specialists

When a deck design has to be right, we should be your first call.

Is space tight? Are you on display to the neighbors? Is this your dream home? We will create a functional space for you, your family, and your friends.

The only complaint we get is that our friends don’t want to leave.

When it comes to details and methods for building decks, with 30 years of experience, we make decks last longer.

Drop by your local building department (or, in current times, call them). Ask them why decks fall off houses. Listen to their reply. The fact is, they don’t know. We do. Ask our designers. We are one of those companies that drops in to see our projects every couple of years.
