Frequently Asked Questions

What does a custom deck builder do (vs. a standard deck installer)?

A custom deck builder designs and builds decks specifically for your property, taking into account yard layout, home architecture, elevation, access points, and how the space will be used day to day. Unlike a standard installer who follows preset layouts, a custom deck builder plans each project from the ground up to ensure the final structure is functional, proportional, and well-integrated with the home. At Kerta Construction, every deck is custom planned with direct involvement from our experienced team. As a family owned Toronto deck builder, we prioritize clear communication, thoughtful design decisions, and hands on craftsmanship- so homeowners feel informed and supported from the initial planning stage through completion.

What types of decks does Kerta Construction build?

Kerta Construction builds custom decks in Toronto and surrounding neighbourhoods as both standalone projects and as part of complete outdoor living spaces. Depending on the property and project goals, decks are often integrated with: • Fencing for privacy and safety • Pergolas or gazebos for shade and structure • Patios and walkways for seamless yard flow • Outdoor kitchens or entertaining areas This integrated approach ensures the entire backyard feels cohesive rather than pieced together over time. Our focus is on building high quality outdoor living spaces that balance visual appeal, functionality, durability, and long term value. Through careful planning and craftsmanship, we create decks that enhance your home and support year round enjoyment of your outdoor space.

What deck materials does Kerta Construction offer?

Kerta Construction specializes in pressure treated wood, cedar, and composite decking, which are the most used and reliable materials for Toronto, ON climate. Each material offers distinct advantages: • Pressure treated wood is cost effective and durable when properly maintained • Cedar decking offers a natural appearance and moderate maintenance requirements • Composite decking is a low maintenance option suited for homeowners seeking long term durability with minimal upkeep Rather than recommending materials based on appearance alone, we walk homeowners through maintenance expectations, lifespan, exposure conditions, and usage needs, helping them choose the option that best fits their lifestyle and long term goals.

How long does a deck typically last?

This is a true differentiating factor for Kerta Construction. We design and build decks with long term performance in mind, knowing that durability and maintenance requirements can vary significantly depending on the materials selected and how the space will be used. With quality construction and routine upkeep, a well built deck can last for many years. Material choice plays a critical role- for example, composite decking is ideal for homeowners seeking a low maintenance solution, while pressure treated wood and cedar decks benefit from regular sealing or staining to protect against Toronto’s changing climate. Rather than taking a one size fits all approach, we help homeowners understand how project materials, exposure, usage, and maintenance preferences all factor into long term results. From planning through completion, our goal is to help you choose the right materials and construction approach, so your deck continues to perform, age well, and deliver value to your home over time.

How long does it take to build a deck?

Timelines for deck construction can vary depending on project scope, material selection, site conditions, and weather, especially in Toronto’s seasonal climate. Larger or more detailed builds, specialty materials, and custom design elements may naturally require additional planning and coordination. That said, what truly sets Kerta Construction apart is consistent, proactive communication throughout the entire build process. From the initial planning phase to final completion, we ensure you always know what stage your project is in, what’s coming next, and why certain steps take the time they do. Rather than leaving homeowners guessing, Kerta Construction focuses on transparency - keeping expectations clear and adjusting timelines thoughtfully when needed. This approach helps reduce stress, avoid surprises, and ensures your deck is built properly, safely, and to a standard that will perform well long term.

What’s the biggest mistake homeowners make when planning a deck?

The most common issue we see on deck projects isn’t craftsmanship- it’s misalignment of expectations early in the planning stage. This most often shows up around deck size and scale, railing style and placement, board colour in natural lighting, and finishing details that look different in real life than they do in photos or samples. At Kerta Construction, we take a proactive, detail first approach to prevent these issues. Before construction begins, we spend time clarifying design decisions, reviewing layout proportions, discussing how materials will look once installed, and walking through finishing details so there are no surprises later. By addressing these elements upfront, we help ensure the finished deck matches what homeowners pictured - not just on paper, but in real world use. This approach reduces stress, avoids mid project changes, and results in a deck that feels intentional, well planned, and cohesive with the home and outdoor space.

How much maintenance does a deck require?

Deck maintenance depends largely on material choice, exposure, and how the space is used. For Toronto homeowners, selecting the right materials upfront plays a major role in long term upkeeping and performance. • Pressure treated and cedar decks typically require routine cleaning and periodic sealing or staining to protect against moisture, sun exposure, and seasonal changes. • Composite decking is a low maintenance option that generally requires only basic cleaning, making it a popular choice for homeowners who want durability with minimal ongoing upkeep. At Kerta Construction, we don’t take a one size fits all approach. We help homeowners compare materials based on maintenance expectations, lifestyle, and long term goals, so your deck remains functional and attractive for years to come.

How often should a wood deck be sealed or stained in Toronto and surrounding neighbourhoods?

In Toronto, ON, climate, wood decks typically benefit from sealing or staining every few years. This helps protect the deck from: • Moisture and snow melt • UV exposure during summer months • Freeze thaw cycles that can impact wood over time Proper sealing or staining extends the life of a wood deck and helps maintain its appearance. We provide clear, straightforward guidance on upkeep, so homeowners understand when and why maintenance is needed, without unnecessary upselling or guesswork.

What are early signs a deck may need repairs?

Catching problems early can help prevent more extensive repairs down the line. Common early warning signs include: • Loose or shifting boards • Visible surface cracking or splintering • Soft or spongy areas underfoot • Railing movement or instability • Fasteners or hardware backing out If any of these issues arise, it’s best to address them promptly. At Kerta Construction, we take an honest, practical approach - evaluating whether simple repairs are sufficient or if broader upgrades should be considered.

Can an existing deck be upgraded instead of replaced?

In many cases, yes. Depending on the structural condition and original build quality, an existing deck may be suitable for upgrades instead of full replacement. Possible upgrades can include: • Replacing decking boards • Updating or reinforcing railings • Improving layout or access • Refreshing finishes or materials We provide transparent assessments so homeowners can make informed decisions—whether that means upgrading what you have or planning a replacement that better suits your long term needs.

Do you help with deck layout and design decisions?

Yes. Deck design is about more than aesthetics—it’s about function, flow, and how the space connects to the rest of your yard. We guide homeowners through: • Layout and proportions • Sightlines and privacy considerations • Access points from the home • How the deck integrates with fencing, patios, and landscaping Our focus is always real-world usability, not just visual appeal.

Can decks and your outdoor living space be designed for entertainment or family use?

At Kerta Construction, this is what fuels us - our decks, patios and outdoor living spaces bring families and friends together every day!
