Double Glazing Windows WF16

Planning replacement windows in WF16

Make a room-by-room list of the windows you want to replace. Note the approximate size, opening style and the problems you hope to address, such as draughts, difficult operation or damaged frames. Explain whether you want to retain the existing appearance or change the layout. A repair enquiry and a complete replacement programme need different quotations.

Compare matching window specifications

Ask each supplier to identify the frame material, finish, glazing and opening arrangement included in the price. Discuss handles, locks, ventilation and any privacy or decorative glass. Offers are easier to compare when they cover the same openings and specification, rather than mixing different product choices into a single headline figure.

Include the work around the frame

Check whether removing the old units, waste disposal, internal making good and work to external trims or sills are included. Mention any awkward access, upper-floor windows or rooms where protecting furnishings needs extra care. Ask how the installation will be organised if several rooms are involved and what access the team will need during the work.

Keep the survey and handover clear

Use the survey to confirm measurements and the final opening arrangements before manufacture. Ask how changes discovered at that stage affect the price and schedule. Request the relevant product and installation documents at handover, together with maintenance instructions and a clear route for aftercare. Compare the coverage and exclusions of guarantees, not simply the number of years advertised.

Preparing your double glazing brief: WF16

Use the points below where they apply to your project. They are questions to discuss with a company, not assumptions about your property or the local area.

Handles and hardware

Ask which handles and other visible fittings are included. Confirm colour and operation choices in writing, particularly if quotations use different product ranges.

Internal decoration

Ask how much internal making good is included around each opening. Clarify whether repainting or other decorative work is part of the quote or something you will arrange separately.

External sills and trims

Check the proposed treatment of external sills and surrounding trims. Include any existing damage in the survey discussion so it is not confused with work included in a standard replacement.

Upper-floor work

Identify windows that cannot be reached easily from outside. Ask what access equipment is expected and whether the quoted price includes the arrangements required for those openings.

Working room by room

If several rooms are involved, discuss the installation order and how long each room needs to be cleared. Agree which furnishings you should move before the team arrives.

Noise concerns

Describe the noise problem you want to address and identify the affected rooms. Ask how the proposed specification relates to that concern rather than assuming all double glazing performs identically.

Ventilation choices

Discuss the ventilation arrangement as part of the complete window design. Ask the surveyor to explain the proposed fittings and how you would use them after installation.

Handover demonstration

Ask the installer to demonstrate the operation of locks and openings before leaving. Record any adjustment needed and keep the maintenance instructions with the guarantee documents.
