Aluminum Window Frame Replacement for Existing Buildings

t503-3

Aluminum window frame replacement means removing an outdated frame and fitting a new, custom-made aluminum frame in the same opening. It improves durability, appearance and how well the window seals, and it is usually planned around the existing opening so the building work stays limited.

When replacing old window frames makes sense

Old wooden or deteriorated metal frames often show signs that it is time to act: warping, gaps that let in air and noise, peeling finishes, or sashes that no longer close properly. Owners of older apartments and buildings frequently find that replacing the frame, rather than only the glass, solves these problems at the source.

Aluminum is a practical choice for existing buildings because it resists corrosion, holds its shape and needs little maintenance. It also allows slimmer sightlines than many older systems, which can refresh the look of a facade without changing its character.

Measuring the existing opening

Accurate measurement is the foundation of a good replacement. The team visits the site, checks the opening in several places, since walls are rarely perfectly square, and records the condition of the surrounding masonry, sills and lintels.

Width and height at top, middle and bottom
Depth of the reveal and the wall thickness
Condition of the sill and any signs of moisture
Direction of opening and access for installation

These readings are turned into a written specification and drawing that the client approves before production begins.

Choosing the profile, finish and glazing

The profile determines how strong the frame is and how it looks from the street. Architects and designers often choose between a slim modern profile and a more traditional section, depending on the building style and the window size. Larger openings usually need a deeper, more rigid profile.

Finishes such as powder coating offer a wide range of colors and a durable surface. Glazing options, including insulated glass units, can be matched to the building's exposure to sun, wind and street noise. Hardware and handles are selected together with the frame so the window operates smoothly over time.

Production in our Tel Aviv workshop

Every frame is built to measure in our factory at 37 Rival Street, Tel Aviv, where cutting, assembly and finishing take place under one roof. Working in-house lets us check each frame against the approved drawing before it leaves the workshop, which reduces surprises on site.

Finishing steps are carried out to suit the project, and the final frames are inspected for square, fit and surface quality so they arrive ready for installation.

Installation with minimal disruption

Installation is planned so the existing wall and interior are disturbed as little as possible. The old frame is removed carefully, the opening is checked and prepared, and the new frame is set, leveled and fixed. Sealing and insulation at the perimeter are important, because a well-fitted frame is only as good as the joints around it.

Where the building has structural or safety requirements, such as window guards or railings, the engineer confirms the details. Exact values are verified with the engineer, and we follow the relevant Israeli standards applicable to the project.

Planning the project with your architect or contractor

For larger buildings, building committees, contractors and interior designers usually coordinate the replacement as one step in a wider renovation. Sharing photos, the existing dimensions and the desired look at the start helps the process move quickly.

Agree on a schedule that suits residents or tenants
Confirm access, protection of floors and any working hours
Approve drawings and specifications in writing before production

Frequently asked questions

How long does aluminum window frame replacement usually take?

The timeline depends on the number of openings, the complexity of the project and the production schedule. Your contact person will give you an estimate once the measurements and specification are approved.

Can I keep my existing glass when replacing the frame?

In some cases the existing glass can be reused if it is in good condition and suits the new frame's dimensions. Your specialist will check this during the on-site visit and advise you honestly.

Will the new frame fit an old opening that is not perfectly square?

Yes, this is common in older buildings. Measurements are taken at several points, and the frame is made to fit the actual opening, with sealing used to close any remaining gaps.

Do I need an engineer for window replacement?

For standard windows an engineer is often not required, but where structural changes, guards or railings are involved, the details are confirmed with the engineer and the relevant standards.

Common mistakes to avoid

A common mistake is ordering frames from rough measurements taken from the outside or from memory, which leads to poor fit. Skipping the written specification and approval step can also result in a color, profile or opening direction that differs from what was expected.

Our recommendation

Measure each opening at three points in width and height, and photograph the sill and surrounding wall before the visit. Decide on profile, finish and glazing together with your architect so the new windows match the building's overall design.

Summary

Aluminum window frame replacement renews an existing opening with a custom frame that is durable, well sealed and suited to the building. Careful measurement, approval of the specification and proper installation are the keys to a result that lasts.
