Deal with draughts and failed glazing

Cold movement around a closed window, mist trapped between panes or a handle that fights back each morning can signal that replacement is due. We assess the frames, seals, glazing and operation before recommending replacement double glazing. New windows can improve thermal comfort, weather resistance, security and the appearance of the property when the product and fitting are right. uPVC gives straightforward upkeep, timber brings natural detail, and aluminium creates slim, clean lines. We help you compare those choices against the building rather than treating every opening the same.

Measured, fitted and sealed with care

A replacement starts with a survey of each opening, including its size, condition and surrounding finish. We then confirm the frame material, opening arrangement, glazing and hardware, with Camden window options and replacement handles available. During fitting, we remove the old unit, secure the new frame and seal the perimeter against the weather. Internal and external edges are finished neatly, and we check that openers, locks and handles work smoothly. You get a clear quotation based on the measured project before installation is arranged.

Frequently asked questions

Does condensation mean my double glazing has failed?

Condensation trapped between the panes usually points to a failed sealed unit. Moisture on the room-facing surface can have other causes, so we inspect the window before advising whether glazing or wider replacement is needed.

Should I choose uPVC, timber or aluminium frames?

uPVC suits low-maintenance priorities, timber provides natural character, and aluminium gives slim lines with strong frames. We compare the options with your property, preferred finish and willingness to maintain them.

What happens during window replacement?

We survey and measure first, then agree the specification. On installation day, we remove the existing window, fit and seal the new frame, finish the edges and test every opener, handle and locking point.
