Not every window problem requires full replacement. A misted double-glazing unit can often be resolved by replacing just the glass unit within the existing frame, provided the frame itself is sound. Broken handles, worn hinges and failed locking mechanisms are generally straightforward repairs. However, if the frame is warped, rotting, or the window is more than 15–20 years old with persistent problems, replacement is usually more cost-effective in the long run.
A trustworthy Window Specialists in Clapham will give you an honest assessment rather than recommending full replacement when a repair would suffice. Our directory helps you find specialists with a reputation for straightforward advice.

Frame Material and Glazing Specification — How They Affect Window Costs
The choice of frame material is a major cost variable. uPVC is typically the most affordable option and requires minimal maintenance. Aluminium frames cost more but offer slimmer sightlines and greater strength, making them popular for large spans and contemporary designs. Timber frames carry a premium for the material and the additional maintenance requirements over their lifetime.
Glazing specification also affects cost. Standard double-glazed units meeting minimum Building Regulations requirements are at the lower end of the price range; triple-glazed, acoustic, solar-control or laminated glass units cost more. The hardware chosen — handle style, lock type, hinge specification — also varies in price. A window specialist in Clapham can help you identify where to invest and where to save based on the location and function of each window.
Frequently Asked Questions — Guarantees, Deposits and Consumer Rights for Windows in Clapham
A comprehensive window installation should come with a manufacturer's warranty on the glass unit (typically 5–10 years against seal failure), a frame guarantee (often 10 years for uPVC, variable for aluminium and timber), a hardware guarantee and a workmanship guarantee from the installer covering the installation itself.
Companies operating under the Consumer Code for Home Improvements provide deposit and guarantee insurance, so your cover continues even if the installer ceases trading. Ask specifically whether the company's guarantee is backed by insurance before signing.
A deposit of 10–25% is typical for window orders where materials are custom manufactured. Never pay more than 25–30% upfront. The balance should be payable on satisfactory completion, not before. Confirm deposit protection before paying anything.
Raise the issue with the installer in writing, detailing the specific defects. If they fail to remedy the problem within a reasonable time, you can escalate to FENSA (for registered installers), the GGF or the relevant consumer code scheme. As a last resort, you have recourse through the courts.
Under the Consumer Contracts Regulations 2013, contracts signed at your home give you a 14-day cooling-off period, provided bespoke manufacturing has not begun. Check the contract for any clauses that attempt to waive this right — such clauses are likely unenforceable.
