Urgency and Emergency Glazing — How Timing Affects Cost in Lewisham
Planned window replacements allow you to obtain multiple quotes, compare specifications and schedule the work at a mutually convenient time, which typically results in the most competitive pricing. Emergency glazing — following a break-in, storm damage or accidental breakage — removes that flexibility. Out-of-hours call-outs, rapid turnaround and the need to hold boarding-up materials in stock all add to the cost of emergency work.
If you have a non-urgent window problem, it is always worth addressing it in a planned way rather than waiting until failure forces your hand. Booking a survey with a Window Specialists in Lewisham at a convenient time will generally result in a better outcome and lower cost than an emergency replacement.
Frequently Asked Questions — Guarantees, Deposits and Consumer Rights for Windows in Lewisham
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.
