If you are wondering who to call to cut a window in a brick wall, hire a licensed masonry contractor. This isn't a DIY job—even small mistakes can crack brick or compromise the structure.

Benefits of Hiring a Mason for Cutting a Window in a Brick Wall

A licensed masonry contractor delivers a safe, code‑compliant installation. Brick is brittle, and cutting it demands specialized tools, training, and structural know‑how. Pros ensure proper support over the opening and seal the new unit to keep moisture out. Hiring a mason reduces safety risks, preserves the wall’s integrity, and prevents permit or code issues that can lead to fines.

• Ensures proper lintel support above the new opening

• Avoids injuries from heavy-duty angle grinders

• Manages permits and adheres to city building codes

• Protects you from fines for unpermitted masonry work

• Properly disposes of removed brick and debris

• Preserves structural integrity of thick, brittle brick walls

• Uses specialized training and brick-cutting tools safely

If you want to ensure the job is done safely and up to code, you might want to consider hiring a mason near you to cut a window in your brick wall.

Can I Hire a Window Contractor for Cutting a Window in a Brick Wall?

Window and general contractors install windows in materials like latex, fiberglass, acrylic, and faux brick. Cutting into real brick, however, requires masonry skills and reinforcement that a window contractor may not provide. Even licensed window installers risk cracked brick or a collapsed wall if the opening is not supported. For structural brick cutting and support, rely on a licensed masonry expert instead of a window contractor.

How Do Pros Cut a Window in a Brick Wall?

Masons start by assessing the structure and confirming the wall can handle a new opening. They clear obstructions inside and outside and plan the support and weatherproofing. The steps below outline a typical process so you know what to expect.

1. Assess load capacity and remove obstructions such as shrubbery, utilities, ductwork, and wiring.

2. Measure the opening and cut the brick using an angle grinder.

3. Penetrate the mortar joints with an angle grinder, hammer, and chisel.

4. Remove brick and install a steel lintel to support the load above.

5. Drill the necessary holes for the window installation.

6. Insert and bolt down the sill and hold-fast clamps; embed hold-fasts in a concrete block.

7. After the cement block cures, clean dust, wet the surface, and plaster with cement mortar to match adjacent finishes.

How Much Does Cutting a Window in a Brick Wall Cost?

Expect to spend from $2,000 to $5,500 on average to add a window to a brick house. This range reflects permit requirements and specialized labor for structural changes. Larger openings cost more, and the window frame material also affects price. Final costs increase when reinforcement or added structural work is needed, and the total varies based on design and the window’s location within the wall.
