How much do contractors charge for bay window install in New Brunswick?

Bay window installation in New Brunswick typically runs $3,500-$8,500 for a standard residential project, with most homeowners paying around $5,500-$6,500 for a quality mid-range installation.

Cost breakdown by window type:

• Vinyl bay windows: $3,500-$5,500 installed (most popular choice)


• Wood bay windows: $5,000-$8,500 installed (premium option)


• Composite/fiberglass: $4,500-$7,000 installed (best durability)

The wide price range reflects several key factors. Window size and projection depth significantly impact cost — a shallow 12-inch projection costs less than a dramatic 24-inch extension. Structural requirements vary dramatically depending on your home's age and construction. Older Maritime homes (pre-1970s) often need additional framing reinforcement, while newer construction may only require minor modifications.

What's typically included in these prices:

• Window unit and hardware


• Structural framing modifications


• Interior and exterior trim work


• Insulation and vapor barrier


• Basic drywall patching

Additional costs to budget for:

• Building permit from your municipality or Regional Service Commission ($150-$400)


• Electrical work if adding outlets or moving switches (requires licensed electrician and NB Power wiring permit)


• Roof modifications for larger projections ($800-$2,000)


• Exterior siding/brick matching ($500-$1,500)

New Brunswick's harsh winters make proper installation critical. The contractor must ensure adequate structural support for snow loads and proper weatherproofing against freeze-thaw cycles. Many bay windows fail prematurely due to inadequate flashing or insufficient insulation around the projection.

Timeline considerations: Most installations take 2-3 days for straightforward replacements, but structural modifications can extend this to a full week. Best installation window is May through September — winter installations are possible but more challenging and expensive due to heating requirements and weather delays.

For a project this complex involving structural changes, definitely hire a licensed contractor. The structural modifications require building permit approval, and improper installation can lead to serious water damage or structural issues.
