What does a full AZEK PVC deck cost for a 300 square foot deck in NB?

A 300 square foot AZEK PVC deck in New Brunswick typically costs $16,500 to $25,500 fully installed, making it the premium option but one that eliminates all future maintenance in our challenging Maritime climate.

AZEK represents the top tier of decking materials, and for good reason in New Brunswick's conditions. The upfront investment of $55-85 per square foot installed reflects the material's superior performance against our freeze-thaw cycles, heavy snow loads, and persistent humidity. Unlike wood decking that requires annual staining and regular board replacement, AZEK's cellular PVC construction is completely moisture-proof and dimensionally stable through our harsh temperature swings from -35°C to +35°C.

For a 300 sq ft deck, your cost breakdown typically includes:

• AZEK decking boards: $8,000-$12,000


• Pressure-treated framing (joists, beams): $3,000-$4,500


• Footings below frost line (1.2-1.5m deep): $2,000-$3,500


• Railings and stairs: $2,500-$4,000


• Labor and permits: $1,000-$1,500

The higher end of the range applies to elevated decks requiring deeper footings, premium AZEK lines like Vintage or Terra collections, or complex designs with multiple levels. Waterfront properties in areas like Grand Lake or the Bay of Fundy often justify the premium cost since AZEK won't rot, warp, or develop mold even in constantly humid conditions.

AZEK performs exceptionally well in New Brunswick's climate because it expands and contracts minimally compared to wood or even composite materials. The closed-cell PVC structure prevents moisture infiltration completely, eliminating the freeze-thaw damage that destroys wood decks within 5-10 years in our climate. You'll never need to power wash, stain, or replace boards due to weather damage.

Consider AZEK if you're planning to stay in your home long-term or want a deck that adds maximum resale value. While the upfront cost is 40-60% higher than pressure-treated lumber, you'll save $600-$1,200 annually on staining and maintenance. Over a 20-year period, AZEK often costs less than wood when you factor in maintenance time and materials.

The ideal building window for AZEK installation runs May through October when contractors can properly install footings below frost line and temperatures allow for optimal material handling. Book your contractor by March since AZEK projects require more specialized installation knowledge.
