Cost to replace an old concrete patio in NB?

Replacing an old concrete patio in New Brunswick typically costs $20-$45 per square foot, depending on the new material you choose and site conditions. For an average 200 square foot patio, expect to budget $4,000-$9,000 total including demolition and installation.

Demolition costs for removing your existing concrete run $3-$6 per square foot, depending on thickness and accessibility. A typical 4-inch residential patio costs around $800-$1,200 to remove and dispose of properly. If there's reinforcement or the concrete is extra thick, costs increase.

New patio material options vary significantly in price. Interlocking pavers are most popular in NB at $18-$30 per square foot installed, offering excellent freeze-thaw durability for our climate. Natural stone like flagstone or limestone runs $25-$45 per square foot but provides a premium look that handles Maritime weather beautifully. Stamped concrete costs $15-$25 per square foot but requires careful installation with proper joints to prevent cracking in NB's freeze-thaw cycles.

Site preparation is critical in New Brunswick's climate. The base must extend below our 1.2-1.5 meter frost line to prevent heaving. Proper drainage is essential given our 1,200mm annual rainfall. If your old patio has settling or drainage issues, expect additional costs for excavation and grading work.

Timing matters significantly for concrete and paver installation. Best installation window is May through September when temperatures stay consistently above 10°C. Fall installations after October risk frost damage to new concrete or mortar. Many contractors offer better pricing for spring bookings made over winter.

Additional factors affecting cost include access to your backyard (narrow gates increase labor), existing utilities that need protection, and whether you're adding features like steps, lighting, or drainage systems. Properties in Moncton, Saint John, or Fredericton with good access typically see lower costs than rural properties requiring equipment transport.

DIY vs professional installation: While homeowners can handle simple paver projects, concrete removal requires proper equipment and disposal. Professional installation ensures proper base preparation, drainage, and warranty coverage. Poor installation leads to expensive repairs within 2-3 years in NB's harsh climate.
