Custom Deck Builder & Gazebos in Moncton, NB

Summer evenings on a deck built for how you entertain. A gazebo that becomes your family's favorite room — the one without walls.

Custom deck and outdoor living space built by Valhalla Construction in Moncton, NB

A deck builder in Moncton gets called for one of two reasons: there is no usable outdoor space yet, or the deck that is there has stopped being somewhere anyone wants to sit. Plenty of outdoor builds across New Brunswick look right the first summer and start coming apart the second, because the footings and drainage were never set up for our winters. Whether the plan is low-maintenance composite, cedar, or pressure-treated, Valhalla Construction designs and builds custom decks and gazebos across Moncton, Dieppe, and Riverview to hold up through Maritime freeze-thaw for years, not seasons.

We design around your property's grade, sightlines, and sun exposure, then build with materials rated for Atlantic Canadian weather — from composite (like Trex and TimberTech) to cedar and pressure-treated wood. Footings below the frost line, correct fastening, and drainage that protects the structure — the details that decide whether your deck is still solid a decade from now. Multi-level decks, built-in seating, privacy screens, glass or aluminum railings, pergolas, gazebos, and space ready for a hot tub — we build the outdoor room around how you'll actually use it, and handle the permits so it is up to code. That is not extra effort. That is the job.

What You Get:

Composite (Trex/TimberTech), cedar, or pressure-treated
Multi-level decks, pergolas, gazebos, and privacy screens
Frost-line footings, proper drainage, and to-code permits
Low-maintenance materials built for Maritime freeze-thaw

What This Covers

A deck or outdoor build covers a range of separate decisions, and it helps to know what each one actually involves. The material, pressure-treated, cedar, or composite, decides the upfront cost and the maintenance for the life of the deck. Railings are their own decision layered on top, in wood, aluminum, or glass, with height and baluster spacing set by New Brunswick code regardless of material.

Whether the project is a new build, a replacement of an existing deck, or a resurfacing over a frame that's still sound is a separate question from all of that, and it changes the scope significantly. Covering the space with a gazebo, a fully roofed covered deck, or a pergola for partial shade is its own layer again, each with different engineering and permit requirements.

Fencing gets built by the same crew, to the same frost-footing standard, when the project is a property line rather than a place to sit.

If your existing deck is showing its age, the first question is whether it needs replacement or just resurfacing — the two are very different jobs and very different budgets.

Most decks we build across Greater Moncton are pressure-treated, the most affordable option when the frame underneath is done right.

Homeowners who want a warmer, more natural finish usually choose cedar decking.

For a lifespan that does not depend on yearly upkeep, there is composite decking, including resurfacing an existing frame with composite boards.

Whatever the decking material, every deck needs railings built to New Brunswick code — wood, aluminum, or glass.

For a space that stays usable rain or shine, we also build gazebos and fully covered decks.

And for partial shade without a full roof, there is pergola construction.

The same crew and the same frost-footing standard also cover fence building for anyone who needs a property line marked rather than a deck built.
