How to Install Replacement Windows in a Brick House
Brick homes are strong, beautiful, and long-lasting. But when it comes to replacing windows, they need special care. That’s because brick doesn’t move like wood or siding. It’s solid and heavy, and if you don't follow the right steps, you could crack the bricks or cause water leaks.
Learning how to install replacement windows in a brick house the right way helps you avoid damage and makes sure the windows stay secure for years. Whether you're doing the job yourself or hiring someone, it’s important to understand how the process works and what to expect.
What to Know Before You Begin Window Replacement
Before you begin, make sure you’re prepared. Here’s what to do:
Measure your windows carefully. Measure both the width and height from the inside edge of the brick opening.
Choose the right type of replacement window vinyl, fiberglass, or wood-clad. Make sure it’s made for brick installation.
Decide between full-frame or insert replacement. A full-frame replaces everything, including the frame. An insert keeps the old frame.
Get the right tools: hammer, pry bar, tape measure, caulking gun, screws, drill, waterproof flashing tape, insulation foam, safety glasses, and gloves.
You’ll also need to check the weather. Never remove a window if rain is expected. A dry, calm day is best.
Step-by-Step: How to Install Replacement Windows in a Brick House
Replacing a window in a brick wall is more detailed than in a wood-framed house. Here's how it’s done:
Step 1: Remove the old window
Carefully take off the interior trim. Score the edges with a utility knife and use a pry bar to remove the trim without damaging the wall. If it’s a full-frame replacement, you’ll need to cut or pry out the old frame too.
Step 2: Clean and inspect the opening
Look for any damage, such as rotted wood or loose bricks. Clean away dust and debris. Make sure the sill is level.
Step 3: Dry-fit the new window
Place the new window into the opening to check the fit. It should be snug but not too tight.
Step 4: Apply flashing and caulk
Use waterproof flashing tape around the sill and sides of the opening. Add caulk to the back of the window’s nailing flange or brickmold if it has one.
Step 5: Install the new window
Place the window in the opening. Use shims to center it and level it. Screw it in through the pre-drilled holes. Recheck for level and plumb.
Step 6: Seal the edges
Use spray foam insulation around the frame gaps. Once dry, trim the extra foam and caulk the exterior edges.
Step 7: Replace the interior trim
Reinstall or replace the interior trim for a finished look.
Full-Frame Window Replacement in Brick Houses

Remove the entire window frame, including the sill and jambs.
Install a new frame made to fit the brick opening.
Flash the sill and sides to prevent water intrusion.

Removing Old Windows Without Damaging Brick

Score all caulk lines between the window frame and the brick using a sharp knife.

Avoid pulling against the brick; work slowly and evenly.
If screws or nails are stuck, cut them with a reciprocating saw.
By taking your time and working gently, you can avoid costly brick damage.
