The cost to enlarge a window in a brick wall is typically $2,000-$7,000, with a national midpoint near $4,000 for a straightforward project. Wider openings, structural reinforcement, interior repairs, permits, and difficult access can push the total above $10,000.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete enlargement | $2,000 | $4,000 | $10,000+ | Labor, masonry work, and basic finish repairs |
| Masonry cutting | $20 per sq ft | $35 per sq ft | $60 per sq ft | Cutting and removing brick; access affects rate |
| Structural engineer | $300 | $700 | $1,500 | More for complex load calculations or site visits |
| New window | $250 | $700 | $2,000+ | Unit price depends on size, frame, and glass |
Typical prices for enlarging a brick-wall window
A modest enlargement, such as adding 6-12 inches to the width or height, often costs $2,000-$4,000 when the opening is accessible and the existing lintel can be modified or replaced without extensive structural work. A larger opening with a new lintel, window, and interior patching commonly reaches $4,000-$7,000.
Projects that widen a load-bearing opening substantially, require scaffolding, or involve extensive brick matching and interior finishing may cost $7,000-$12,000 or more. The total assumes a standard replacement window, ordinary access, and no major concealed damage.
Assumptions: Typical U.S. contractor rates, a ground-floor opening, standard brick veneer or masonry, and basic interior repairs.
What masonry, framing, and labor add to the quote
Quotes should distinguish cutting and rebuilding from the window itself. Ask whether the price includes temporary support, a properly sized lintel, weatherproofing, disposal, and repairs on both sides of the wall. Brick matching can be a meaningful expense if the original brick is discontinued or weathered.
| Quote component | Typical range | What it covers | Common price driver |
|---|---|---|---|
| Masonry cutting and removal | $500-$1,800 | Saw cutting, brick removal, debris handling | Opening size and access |
| Lintel and structural work | $400-$2,000 | Steel or reinforced support and installation | Span and load above opening |
| Window and installation | $600-$2,500 | Unit, flashing, setting, and sealing | Window type and dimensions |
| Interior and exterior finish | $300-$1,800 | Drywall, trim, mortar, and brick patching | Finish quality and brick availability |
| Engineering and permits | $300-$1,500 | Plans, review, and inspection charges | Local requirements and complexity |
Check for exclusions such as paint, trim, scaffolding, and debris hauling before comparing bids. Labor is often included in the line items above; when itemized separately, masonry or carpentry labor may run about $50-$100 per hour.
How opening width, lintel span, and brick type affect cost
Opening dimensions are a major structural cost driver. A change of just a few inches may be manageable, but widening a window beyond the existing lintel’s supported span can require a longer steel lintel and temporary shoring. A new lintel and installation may add $400-$2,000, while complex structural support can add more.
Brick veneer over wood framing is generally less involved than a solid masonry wall, though both require proper support and water management. Cutting a 3-by-4-foot opening is typically less expensive than creating a 5-by-5-foot opening, which removes more masonry and may require a stronger support. Wall construction and the final opening size should be confirmed before a firm quote is accepted.
Do permits and engineering raise the brick-opening bill?
Many jurisdictions require a permit when a window opening changes, especially if the wall is load-bearing or the alteration affects emergency egress. Permit fees often fall around $100-$500, but plan review and inspections can bring the total higher. Requirements and fees vary by city and county.
A structural engineer may charge $300-$1,500 for a site assessment and calculations, depending on the scope. This expense is more likely when the opening is widened, the wall carries floor or roof loads, or the local building department requests stamped plans. Confirm permit and engineering requirements with the local building department before construction begins.
How long cutting and installing a larger window takes
A straightforward job may take 1-3 workdays on site, with additional time for permit approval, custom window ordering, mortar curing, or finish work. A small crew may include a mason and carpenter, with a glazier or installer setting the unit. Contractors may charge more for tight urban access, upper-story scaffolding, or work that needs weather protection.
Some bids quote a project total rather than hourly labor. If billed by time, a two-person crew at combined rates of roughly $100-$200 per hour for 10-20 hours would represent $1,000-$4,000 in labor before materials and other charges. Ask whether the estimate includes setup, cleanup, and return visits for finishing.
Three brick-window enlargement quotes by project scope
| Example | Scope and labor | Estimated total |
|---|---|---|
| Small height increase | Approx. 3-by-4-foot opening; standard window; 12-16 crew hours | $2,400-$3,800 |
| Wider living-room opening | Approx. 5-by-4-foot opening; new lintel; 20-30 crew hours | $4,500-$7,000 |
| Large structural change | Approx. 6-by-5-foot opening; engineering, shoring, brick matching; 30-45 crew hours | $7,500-$12,000+ |
Examples assume a replacement window and ordinary regional labor rates; permit costs, specialty glass, and premium finishes may change totals.
Use project scope, rather than the window’s purchase price alone, to judge whether quotes are comparable.
When a smaller repair costs less than enlarging the opening
If the goal is more light or improved operation, replacing the existing window within its current opening can cost roughly $800-$2,500 installed for a common unit. Repairing failed hardware, weatherstripping, or a damaged sash may cost about $150-$700, depending on parts and labor.
These options do not create a larger view or increase the opening, but they can avoid masonry cutting, lintel work, and interior repairs. Compare the value of a larger opening with the added structural and finish costs before committing to a size change.
Ways to control the cost of a brick window enlargement
Keep the new opening as close as practical to the existing dimensions, since a smaller change may avoid a longer lintel and extensive brick removal. Choose a standard-size window when it fits the design; custom dimensions, specialty glass, and premium frames can raise material costs. Confirm the required finished opening before ordering.
Get at least three written bids with the same opening dimensions and a clear breakdown for engineering, permits, masonry, window installation, finishing, and disposal. Schedule the work when contractors have availability rather than requesting rush service, and handle simple room clearing yourself. Do not cut costs by skipping structural support, flashing, or required inspections.
