Our success has been helped by our ability to problem solve, organise and run major maintenance and refurbishment schemes without a main contractor.

Plus the ability to identify and rectify problems that other Companies walk away from, particularly in occupied sites.

We are able to deal directly with the client, Architect or Main Contractor removing existing installations and replacing with steel, aluminium and plastic glazed products.

We will carry out a detailed survey of existing windows and submit a report listing details of the conditions of windows and recommendations on security, weathering, safe operation and any alterations that may be required.

Such reports may also confirm the availability of replacement parts and list costings for any scheduled repairs.

We will provide quotations based on the number of windows and the scope of the required report.
