Deck Waterproofing – Double Your Outdoor Living Space

At Green Side Up Contracting, we believe that a well-designed deck should do more than just provide a surface for outdoor enjoyment—it should maximize your usable outdoor space. Too often, homeowners and inexperienced contractors overlook the potential of the area beneath the deck. With the right waterproofing system, you can transform this underutilized space into a dry, functional area perfect for relaxation or storage.

Why Deck Waterproofing Matters

Waterproofing your deck protects the entire structure from moisture damage, extends its lifespan, and enhances your outdoor experience.

As a TrexPro Platinum Professional, we recommend Trex RainEscape, an industry-leading deck drainage system designed to keep the underside of your deck completely dry. This deck waterproofing membrane is installed between the joists during construction, offering unparalleled protection and opening up endless possibilities for your outdoor space.

Deck Restoration

Deck restoration is rejuvenating an existing deck by repairing and resurfacing the deck boards and railing rather than replacing the entire deck. This process involves inspecting the deck’s footers and framing, replacing damaged components, and installing new deck boards and railings. Our restoration process ensures your deck is safe, functional, and visually appealing while significantly increasing its longevity. Using materials such as Trex composite decking, we can breathe new life into your deck, transforming it into a beautiful and low-maintenance deck. This process will save you significant money, and a permit is not required to do this task.

Deck Restoration Process

deck footer inspection

1. Inspection of Footers and Framing

The first step in restoring a deck is to assess the condition of its foundation. Footers are inspected to ensure they are structurally sound. The framing, including joists and beams, is also checked for rot, damage, and levelness. If the deck is enclosed or difficult to access, a few boards may be removed for a thorough evaluation.

2. Assessment for Restoration Feasibility

Based on the inspection, we determine whether the deck can be restored with approximately 80% accuracy. While no inspection is 100% foolproof, our experienced consultants provide a highly accurate assessment to guide the restoration process.

3. Frame Repair and Reinforcement

If any of the framing components, such as joists or beams, are found to be compromised, they can be replaced or reinforced (“sistered”). This ensures the structural integrity of the deck for years to come.

Joist and Beam Protection

4. Joint and Beam Protection

After repairing or reinforcing the framing, we apply a protective epoxy to the top of the joists and beams. This step is crucial to extending the lifespan of the deck, as it shields the wood from moisture and weather-related damage.

5. Deck Board Installation

Once the structure is secured, new Trex Composite deck boards are installed. Trex is a high-quality, low-maintenance material that resists fading, staining, and scratching. It is an ideal choice for deck restoration as it combines aesthetics with durability.

6. Rebuilding the Steps and Railings

The final steps in the process include rebuilding the stairs (which often need replacing in older decks) and installing a new railing system. This completes the transformation of the deck into a modern, functional outdoor space.

ADVANTAGES

Benefits of Deck Restoration

Restoring your deck not only improves its appearance but also extends its life. Our process focuses on enhancing safety, performance, and curb appeal with lasting results.

01

Enhanced Safety

Restoring a deck ensures its structural components are secure and stable, enhancing overall safety for family and guests. Repaired joists, posts, and railings reduce trip hazards and meet current best-practice standards.

02

Minimal Disruption

Since the framework remains intact, deck restoration is less messy and time-consuming compared to full deck replacement. Most projects finish faster with fewer dumpster loads and less impact on your yard.

03

Lower Cost

Restoring a deck is significantly more affordable than replacing it entirely, as only the damaged components are repaired or replaced. You keep the good structure and invest only where it counts.

04

Second-Story Waterproofing Option

For elevated decks, waterproofing options can be added to protect the deck’s framing and create a dry, usable space beneath it. Add lighting, fans, or storage under-deck for year-round functionality.

05

No Permit Required

In most cases, deck restoration does not require a building permit, streamlining the process and avoiding bureaucratic delays. We’ll confirm local bylaws first to keep everything compliant.

06

Increased Property Value

A well-maintained deck adds significant value to your property, improving both functionality and curb appeal. Fresh surfaces, safe stairs, and modern railings make a strong impression at resale.

Frequently Asked Questions

The right deck material will look different to each homeowner. It’s important to know your priorities – how you want your deck to look, feel, and function – to help you choose the right material.

These are the factors you will want to consider when determining the best decking material for your backyard:

Durability

If durability is your primary concern, composite Trex materials are ideal for your deck design. Trex decking does not warp or change over time and is engineered to withstand various elements, from rotting and insects to severe weather changes.

Aesthetics

If you want to maximize your visual appeal and customization options, cedar wood decks can be altered to meet nearly any desired deck aesthetic. They can also be left untreated or stained to maintain their original appearance.

Budget

For budget-conscious homeowners, pressure-treated decks are known for their cost-effectiveness without sacrificing durability. Regular maintenance, including staining and sealing, will help maintain their longevity.

Composite decks are also a great solution if you’re looking for an affordable alternative without maintenance. While their upfront costs may be higher than their wood counterparts, Trex decks require zero maintenance, saving you money over a longer period.

Composite decking is a low-maintenance and versatile deck design that looks and handles like wood but is typically made from either PVC, wood flour, polyethylene, or a blend of polypropylene. This style is available in various deck colours, patterns, and sizes for maximum customization.

Composite decking is known for its durability, cost-effectiveness, and ability to resist Canada’s seasonal weather conditions.

Trex decking is an environmentally conscious alternative to other decking solutions. The Trex deck construction process involves using a wood fibre–polymer composite material to build a deck structure that can withstand natural elements, resist mould and mildew, and avoid fading or scratching.

Trex composite decking offers a wide range of benefits to homeowners looking for a wood alternative solution for their project. Trex composite decking:

  • Requires Zero Staining
  • Saves Time & Money
  • Is Environmentally-Friendly
  • Is Long-Lasting Durability
  • Resists of Chips and Splinters
  • Will Never Rot or Scuff
  • And is Insect and Termite-Proof

Let our composite deck company help you see the benefits of Trex decking first-hand.

Cedar and composite decking are both popular materials for deck construction. However, they are unique in their construction, costs, and benefits.

Cedar is available in a variety of grades, which means cedar decks can create virtually any desired look. It’s known for being easy to cut and lay flat, allowing for unique patterns and visual markers. Since it’s resin-free, cedar can effortlessly hold various finishes. It’s naturally insect-resistant, with an average lifespan of 25+ years.

Composite decking is made from recycled materials, making it an eco-friendly solution that you can customize to resemble a more realistic wood grain. Composite decks are renowned for their durability and resistance to fading, staining, and mould. The average lifespan of a composite deck is between 30 and 50 years.

Pressure-treated decking is made from natural wood and treated with chemicals to resist rot, decay, and insect damage. This material is typically more affordable upfront but requires regular maintenance, like staining and sealing, to maintain its appearance and structural integrity.

Composite decks, on the other hand, are made from a blend of wood fibres and recycled plastic; they are known for their durability and resistance to insects, rot, and warping. Although the cost of a composite deck is typically higher upfront, it requires minimal maintenance, which can save buyers money over time.

Yes, you can use pressure washers on composite decks. However, it’s recommended that you do not exceed 3100 psi pressure, and it’s kept at least nine inches away from the deck boards.

Typically, any deck in Toronto or York Region that exceeds two feet in height and is larger than 108 sq. ft. requires a building permit. Permits are also required if an existing deck is undergoing a structural renovation.

Permits require several pieces of information, including detailed footings, sizes and locations of all columns, stair and guard construction details, and surveys or site plans. Our composite deck builders will outline the requirements for your permit and ensure all paperwork is submitted on time and to the appropriate departments before deck construction begins.

Creating a custom deck is a specialized process and can vary in duration, depending on the project’s style, size, and shape. Working with a custom deck contractor typically includes approving various renderings, submitting permits, and selecting materials and finishes — all of which can take time.

At Green Side Up, we offer a free discovery call, during which potential clients can discuss their composite and Trex decking needs, budgets, and timelines. With these insights, we can provide a better estimate for your deck construction project’s timeline.

Installing Trex composite decking in Canada can vary based on several factors, including the size and scope of the project and the level of customization required.

Working with our composite deck company means you’ll never have to guess how much your deck construction project will cost. We work closely with our clients to determine their budgets and help them build Trex deck designs that offer affordability without sacrificing quality.
