Common Mistakes to Avoid When Building a PVC Deck in Ottawa
Building a **PVC deck** is an excellent investment for homeowners in Ottawa, providing **durability, low maintenance, and weather resistance**. However, improper installation and planning mistakes can **reduce your deck’s lifespan and performance**. To ensure a long-lasting and beautiful deck, avoid these **common PVC decking mistakes**.
1. Choosing the Wrong PVC Decking Material
Not all PVC decking materials are created equal. **Low-quality PVC boards** may fade, warp, or crack over time, especially under Ottawa’s extreme weather conditions. To ensure longevity, choose a **premium PVC brand** like Azek PVC Decking, known for its superior **UV resistance, durability, and fade-proof technology**.
2. Improper Deck Foundation & Support
One of the most critical aspects of deck construction is a **solid foundation**. Common mistakes include:
- **Insufficient footings** – Deck posts must be installed below Ottawa’s **frost line** to prevent shifting.
- **Incorrect spacing of joists** – PVC decking requires **proper joist spacing** (typically 12”-16” apart) to prevent sagging.
- **Weak fasteners or brackets** – Using low-quality hardware can lead to structural instability.
3. Not Allowing for Expansion & Contraction
Unlike wood, **PVC expands and contracts** with temperature changes. Failing to **leave proper spacing** between boards can cause buckling and warping. Follow **manufacturer guidelines** for spacing to ensure long-term durability.
4. Ignoring Proper Drainage
Water accumulation under your deck can lead to **mold, mildew, and structural damage**. Avoid these drainage mistakes:
- **No slope or pitch** – PVC decks should have a slight **slope for water runoff**.
- **Poor under-deck ventilation** – Trapped moisture under the deck frame can cause rot in supporting structures.
- **Blocked drainage gaps** – Keep **gaps between boards clear** to allow proper water flow.
5. Using the Wrong Fasteners or Installation Method
PVC decks require **hidden fastener systems** or **stainless steel screws** designed specifically for synthetic materials. Using **improper nails or screws** can lead to cracks and loose boards over time.
6. Not Considering Sun & Heat Reflection
PVC decking can retain heat, especially in **dark colors**. If your deck is in **direct sunlight**, consider:
- Choosing **lighter-colored PVC boards** to reduce heat absorption.
- Adding a **pergola or shade structure** for comfort.
- Selecting a **heat-resistant PVC brand** designed for hot climates.
7. Poorly Planned Stairs & Railings
Stairs and railings are essential for **safety and aesthetics**. Common mistakes include:
- Incorrect **stair rise/run measurements**, making them uncomfortable or unsafe.
- Skipping **railings or using unstable materials**, which can lead to accidents.
- Not following **Ottawa building codes** for deck safety.
8. Skipping Professional Installation
While **DIY deck projects** can be rewarding, mistakes in **foundation, spacing, and fastening** can **shorten your deck’s lifespan**. Hiring a **professional deck builder** like MyDeck Ottawa ensures proper installation and long-term durability.
Conclusion
Avoiding these common mistakes when building a **PVC deck** in Ottawa will help ensure **longevity, structural integrity, and beauty**.
