About deck & patio services
Deck and patio work covers building outdoor living surfaces and the structure that supports them. Decks are raised or ground-level platforms framed in pressure-treated lumber and topped with wood or composite boards, with railings, stairs, and sometimes built-in benches or pergolas. Patios are at-grade surfaces built from pavers, natural stone, or poured concrete over a prepared base. Many contractors build both, and larger projects combine them, such as a raised deck off the back door stepping down to a paver patio and a fire-pit area in the yard.
Homeowners hire deck and patio builders to add usable outdoor space, replace an aging or unsafe structure, or increase the enjoyment and value of a property. A rotting deck with soft boards and wobbly railings is a common trigger, since a failing deck is a genuine safety risk. Others are starting fresh, expanding a small landing into a full entertaining area, adding stairs and lighting, or switching from high-maintenance wood to low-maintenance composite decking. In Canada, frost-depth footings and proper drainage are essential so the structure does not heave or rot through freeze-thaw cycles.
Deck and patio costs swing widely with size, materials, height, and site conditions, and quality is easy to hide until it fails. A deck with undersized footings, improper flashing where it meets the house, or joists spaced too far apart may look fine and still be unsafe. Because much of that structure is bolted together before the decking hides it, comparing detailed quotes is your best safeguard. Estimates that specify footing depth, framing lumber, fastener and flashing details, and the exact decking and railing products let you compare real construction quality, not just the finished look.
Deck & Patio services we cover
New deck construction
Designing and building raised or ground-level decks from the footings up, including framing, decking, railings, and stairs. A new deck is engineered for the loads it will carry and the site it sits on.
Composite and PVC decking
Installing low-maintenance composite or PVC boards that resist rot, fading, and splinters. Composite decking costs more up front than wood but skips the annual staining and sealing that pressure-treated lumber needs.
Paver and stone patios
Building at-grade patios from interlocking pavers or natural stone over a compacted base. Proper base prep and edge restraint are what keep a paver patio from settling, shifting, or sprouting weeds.
Deck repair and rebuilds
Replacing rotten boards, reinforcing framing, upgrading railings to current standards, and re-flashing the ledger where a deck meets the house. Repairs restore safety without always rebuilding from scratch.
Railings, stairs, and pergolas
Adding code-compliant railings and stairs, plus features like pergolas, privacy screens, built-in benches, and lighting. These finishing elements shape how the space is used and how safe it is.
Concrete patios
Pouring at-grade concrete patio slabs, plain or stamped, on a compacted base with drainage slope. A poured patio gives a seamless surface that pairs well with a deck or outdoor kitchen area.
Signs you need a deck & patio pro
Soft, rotting, or splintering boards
Deck boards that feel spongy underfoot, show rot at the ends, or splinter badly are past their service life. Soft framing beneath the surface is a safety concern that needs prompt inspection.
Wobbly railings or stairs
Railings that move when you lean on them and stairs that flex or feel loose are hazards, especially on a raised deck. Loose connections and rotten posts are common causes and should be fixed right away.
Sinking or heaving patio
Pavers or slabs that have settled unevenly, lifted at the edges, or pooled water point to a base that was poorly compacted or is heaving with frost. Relaying on a proper base solves it for the long term.
Outgrowing a small landing
A cramped landing or a bare patch of yard that you wish were usable outdoor space is reason enough to build. Adding a deck or patio expands where you can cook, gather, and relax.
What drives deck & patio cost
See the full cost guide →Size and height
Square footage is the obvious driver, and height adds more. A raised deck needs taller posts, more bracing, stairs, and railings, all of which increase both materials and labour over a ground-level build.
Decking and railing material
Pressure-treated lumber is the most economical, cedar sits higher, and composite or PVC decking with matching railings costs the most up front while cutting long-term maintenance. Paver and stone choices vary widely too.
Footings and site conditions
Frost-depth footings, sloped or rocky ground, poor soil, and difficult access all add excavation and labour. A flat, accessible yard is far cheaper to build on than a steep or obstructed one.
Features and permits
Stairs, multiple levels, pergolas, built-in seating, lighting, and privacy screens each add cost, and many decks require a building permit and inspection, which adds fees and time to the project.

Deck patio in Canada
Across Canada, deck patio needs vary from one province to the next. With long winters across much of the country, work in Canada has to account for frost heave, ice and the swing between deep cold and summer heat.
Typical jobs include composite and pvc decking and concrete patios. Requirements vary by province and municipality, and many jobs need a permit, so a local contractor who knows the regional code saves headaches.
On NeedReno you can find deck patio pros throughout Canada, compare quotes in Canadian dollars, and choose a contractor who already works in your province.
How to choose a deck & patio contractor
Hire a deck or patio builder who works to the building code and pulls the permit when one is required, which for most raised decks it is. Ask how deep they set footings, since in Canada they must reach below the local frost line to prevent heaving, and confirm how they flash and attach the ledger to the house, because improper ledger connections are a leading cause of deck failures. Check that the contractor carries liability insurance and workers compensation coverage, and ask to see decks they built a few years ago so you can judge how the work has aged through real winters.
Collect at least three itemized quotes and make sure each specifies the framing lumber, footing depth, fastener and flashing details, and the exact decking and railing products, so you are comparing construction quality rather than just price and appearance. Be cautious of a bid that is far lower, as the saving often hides shallow footings, wider joist spacing, or cheaper hardware you will not see until something sags. Ask about the warranty on both labour and the decking product, and read reviews for mentions of solid, level, squeak-free results that have held up, along with a clean and respectful worksite.
What to expect from a deck & patio project
Design and quote
The builder discusses how you will use the space, measures the site, checks grade and access, and proposes a layout and materials. You get an itemized quote and, where needed, drawings for a permit application.
Permits and layout
Required permits are pulled and the footprint is laid out and marked. Utility locates are arranged before any digging so footings do not hit buried services.
Footings and framing
Footings are dug below frost depth and poured or set, posts and beams go up, and the ledger is flashed and fastened to the house. Joists are installed at the correct spacing to carry the load.
Decking or surface install
Decking boards are laid and fastened, or pavers and stone are set on the compacted base with edge restraint. Railings, stairs, and any pergola or lighting are added at this stage.
Inspection and finishing
Where a permit applies, the build is inspected, then final details like fascia, trim, and clean-up are completed. The builder reviews maintenance and any product warranties with you.
Deck & Patio: frequently asked questions
Do I need a permit to build a deck?
In most Canadian municipalities you need a building permit for a deck above a certain height or size, and raised decks attached to the house almost always require one plus an inspection. Ground-level platforms below the threshold sometimes do not. Rules vary by city, so confirm with your local building department or let your contractor handle it. A reputable builder will pull the permit and build to code rather than skipping it, which protects you at resale.
Composite or wood decking, which should I choose?
It comes down to budget and maintenance. Pressure-treated wood and cedar cost less up front but need regular cleaning, staining, or sealing and will eventually weather and splinter. Composite and PVC decking cost more initially but resist rot, fading, and splinters and need only occasional washing, so they often win over the long run. If you want a natural look and do not mind the upkeep, wood is fine; if you want low maintenance, composite is the usual choice.
How much does it cost to build a deck?
Deck cost depends on size, height, materials, footing requirements, and features like stairs, railings, and lighting. A small ground-level pressure-treated deck sits at the low end, while a large raised composite deck with multiple levels costs considerably more. Site conditions and permits add to it. The dependable way to budget is to get a few itemized quotes that spell out the structure and materials so you can compare real scope rather than a single headline number.
How deep do deck footings need to be?
In Canada, deck footings for a permanent structure generally must extend below the local frost line so seasonal freezing does not heave the deck. That depth varies by region and is often more than a metre in colder areas, and it is set by your local building code. Getting footing depth right is one of the most important structural details, so ask any builder exactly how deep they dig and confirm it matches your municipality's requirement.
How long does a deck take to build?
A straightforward ground-level deck can go up in a few days once materials are on site, while a large raised deck with stairs, railings, and multiple levels can take a couple of weeks. Permit approval, footing inspections, and weather can extend the timeline. Your builder should give you a schedule that accounts for the permit process and any inspection hold points, so you know when digging starts and when you can use the finished deck.
What is the difference between a deck and a patio?
A deck is a framed structure, usually raised on footings and posts, with a wood or composite surface, which suits sloped yards and lets you step out at door level. A patio is an at-grade surface of pavers, stone, or poured concrete laid on a compacted base, which suits flat ground and tends to need less structural framing. Many yards use both together, with a deck off the house stepping down to a patio.
