What information is needed to quote for curtain wall replacement?

The most useful information for a curtain wall replacement quote is a clear description of the required work, the condition of the surrounding system, the specification expected for the replacement and any practical constraints affecting installation. The more complete the information, the more accurately GlassPlus UK can define the scope and identify whether a site survey is needed before the quotation is finalised.

Details that help define the scope

• Whether the requirement is for isolated glazing units, a larger section of curtain walling or associated framing components.
• The reason for the proposed replacement, such as impact damage, failed seals, leaks, corrosion, movement or a change to the building’s requirements.
• Any visible damage to adjacent mullions, transoms, pressure plates, gaskets, beads, seals, drainage paths or internal finishes.
• Whether the work forms part of a wider refurbishment, insurance claim, planned maintenance programme or repair following an incident.

Existing system and replacement requirements

Information about the curtain walling system can help establish compatible replacement materials. Useful records may include previous repair details, maintenance reports, glazing specifications, facade schedules and information on the original installer or system design. If these records are unavailable, GlassPlus UK can assess the visible construction and identify the information that must be confirmed during a survey.

The quotation should also state any required glass characteristics, such as safety performance, solar control, thermal performance, acoustic requirements, appearance or matching of existing units. Where the replacement must match retained glazing, details of the desired tint, coating, reflectivity and spacer appearance can be important. The final specification may need to account for current building and safety regulations rather than simply replicate a damaged unit.

Information about the building and its use

• The type of commercial premises and the areas affected, including whether the work is within an occupied or sensitive environment.
• Any restrictions relating to tenant operations, public areas, deliveries, noise, dust, security or the protection of nearby equipment and finishes.
• The name and role of the person authorised to approve the quotation and coordinate access or site information.
• Any landlord, managing agent, insurer, principal contractor or consultant requirements that must be reflected in the quotation.

Documents and site information

Relevant surveys, inspection reports, defect notifications, maintenance records and consultant specifications should be supplied where they exist. A marked-up elevation or schedule identifying each affected opening is particularly useful when several areas are involved. It reduces uncertainty over quantities and helps ensure that associated components are considered rather than pricing the glass in isolation.

A site inspection may still be appropriate where the system cannot be identified from the available records, damage extends beyond the visible glazing, measurements are difficult to verify or the installation method depends on conditions within the facade. The survey can confirm dimensions, interfaces, materials and the practical scope before GlassPlus UK issues or confirms the quotation.

To begin, the client should send the available project information together with the preferred specification and any commercial or site restrictions. GlassPlus UK can then review the brief, clarify any gaps and advise whether further inspection or documentation is required to produce a properly defined curtain wall replacement quotation.
