What is the cost of widening doorways for wheelchair access in a NB home?

Widening doorways for wheelchair accessibility in New Brunswick typically costs $800-$2,500 per doorway, depending on whether the wall is load-bearing, the type of construction, and the extent of finishing work required. Standard interior doorways (32 inches) need to be widened to 36 inches minimum for wheelchair access, though 38-40 inches provides more comfortable clearance.

The cost breakdown varies significantly based on the wall type. Non-load-bearing interior walls are the most straightforward modification, typically costing $800-$1,500 per doorway. This involves removing the existing door and frame, cutting back the wall studs, installing a new wider frame, patching and finishing the drywall, and installing the new door. The work requires careful cutting to avoid damaging electrical wiring or plumbing that may run through the wall cavity.

Load-bearing walls require structural modifications and cost $1,500-$2,500 per doorway. A structural engineer must assess the load requirements and specify the proper header size to carry the load across the wider opening. This typically involves installing a laminated veneer lumber (LVL) or steel beam header, which requires temporary support during installation. The additional structural work, engineering consultation, and building permit requirements drive up the cost significantly.

Exterior doorway widening is the most complex and expensive modification, often costing $2,000-$4,000 or more. This involves modifying the structural framing, installing proper flashing and weatherproofing, matching exterior siding or brick work, and ensuring the new opening meets building code requirements for structural integrity and energy efficiency. In New Brunswick's harsh climate, proper air sealing and insulation around the modified opening is critical to prevent moisture infiltration and heat loss.

The type of door affects the total project cost. Standard hinged doors cost $200-$600 for a quality 36-38 inch door. However, many homeowners opt for pocket doors or barn-style sliding doors to maximize clear opening width and eliminate the door swing that can impede wheelchair navigation. Pocket doors require additional framing modifications and cost $400-$800 for the door hardware, but they provide the most accessible solution.

Flooring transitions often need modification during doorway widening projects. Removing sections of hardwood, tile, or carpet to accommodate the wider opening and ensuring smooth transitions between rooms adds $200-$500 per doorway. In older NB homes, this work sometimes reveals subfloor issues that require additional repair.

Electrical and plumbing considerations can add unexpected costs. Light switches, outlets, or plumbing lines running through the wall may need relocation. TSANB-licensed electricians charge $150-$300 to relocate switches or outlets, while plumbing modifications require licensed plumbers and can cost $300-$800 depending on complexity.

Permit requirements vary by municipality. Structural modifications to load-bearing walls require building permits in most NB communities, typically costing $100-$300. The permit process includes structural plan review and inspection, adding 2-4 weeks to the project timeline.

Timing considerations for NB homes include allowing materials to acclimate to indoor temperatures, especially during winter months. Drywall compound and paint require proper temperature and humidity for curing. Interior accessibility modifications can proceed year-round, but plan for 3-5 days per doorway including drying time for finishes.

Professional requirements include hiring a structural engineer for load-bearing wall modifications ($500-$1,200 for assessment and stamped drawings), TSANB-licensed electricians for any electrical work, and experienced carpenters familiar with accessibility modifications. Many general contractors can handle non-load-bearing doorway widening, but structural modifications require specialized expertise.

For multiple doorway modifications, contractors often provide package pricing that reduces the per-door cost by 10-15%. Budget an additional 15-20% contingency for older NB homes where hidden conditions like outdated wiring, plumbing conflicts, or structural surprises are common.
