How Professionals Replace Windows in Brick Homes

Replacing an aging window can feel daunting when you worry about damaging the surrounding brickwork. Professional window installation in Lawrenceville, GA, helps protect that masonry while providing a secure, weather-resistant fit.

Learn how professionals install windows in a brick home and what to expect during replacement.

Assessing the Existing Frame and Measuring the Opening

An insert replacement may be suitable for a dry, square frame without rot. Soft or water-damaged framing may require removing the entire frame to repair underlying problems.

Installers prepare the window opening based on how the walls are built. Brick veneer is an outer layer of brick with a drainage gap between it and the supporting wall. Solid masonry walls provide their own structural support, so they require a different approach to window installation.

Accurate window frame measurements, taken at several points along the opening’s height and width, help ensure proper sizing within manufacturer-specified clearances. 

Removing the Old Window and Preparing the Opening

Masonry opening preparation involves these steps:

  1. Carefully remove old components to protect nearby brickwork and interior finishes.
  2. Clear loose debris and worn sealant from exposed surfaces.
  3. Repair any framing damage exposed during removal before installing the replacement.

Brick veneer removal is usually unnecessary when a replacement fits within the existing opening. Enlarging it may require alterations to surrounding masonry.

Managing Water Around the Window Opening

During full-frame replacement, flashing and waterproofing must integrate with the existing weather barrier to direct water safely outside.

Proper layering creates a drainage path, while clear weep holes allow moisture to escape. Although flashing becomes concealed as installation progresses, it continues to protect the surrounding framing from water damage.

Positioning and Securing the Replacement Window

Wall construction and manufacturer requirements determine how to install windows in a brick home. Installers position the replacement unit on shims to keep it level, plumb, and square before fastening.

Window installation in brick walls may require screws driven into framing or suitable masonry anchors. Overtightening fasteners or forcing shims too tightly into gaps can bow the frame, so installers check alignment throughout the fitting.

Sealing Gaps and Checking the Finished Installation

Window sealing and insulation close gaps around the replacement frame to help limit drafts. Installers use low-expansion foam designed specifically for doors or windows.

Installers use a compatible exterior sealant to seal designated joints per the manufacturer’s instructions. They then refit trim without blocking sill drainage openings, allowing moisture to escape.

Before finishing, installers check that the sash moves smoothly and its lock engages properly. They also inspect completed joints for gaps, then clear debris from the work area.
