WINDOW KNOW-HOW
What you need to know to plan ahead, budget properly and hire the right Window Specialist.
RULES & STANDARDS
You should receive a FENSA or CERTASS certificate within a few weeks of completion — chase it if it hasn't arrived, since some installers register the job but delay sending the physical certificate. Keep it with your house paperwork; you'll need it when you sell.
GOOD TO KNOW
For a broken window (break-in, accident, storm damage), boarding up is usually a same-day emergency service separate from full replacement, which follows the normal survey-to-fitting timeline. Ask specifically about emergency call-out availability if security is an immediate concern, not just repair timing.
SAFETY & COMPLIANCE
A quote well below others is worth questioning — check it specifies the same glazing spec (U-value), includes the FENSA/CERTASS certificate, and covers disposal of old windows. High-pressure doorstep sales tactics and "today only" pricing are worth treating with real caution in this trade specifically.
COST & QUOTES
Three is a reasonable number — window quotes can vary significantly based on glazing spec and frame quality, so make sure each quote specifies the same U-value and frame material before comparing prices directly.
COST & QUOTES
A conservatory is predominantly glazed (roof included); an orangery has more solid roof/brick structure with a glazed lantern; a garden room is typically a fully insulated, solid-roofed structure suited to year-round use. Building Regulations requirements differ between these, so it's worth clarifying which you're actually getting quoted for.
USEFUL TO KNOW
Standard double glazing reduces noise somewhat, but for a genuinely noisy location (busy road, flight path), acoustic glazing with a wider gap between panes or laminated glass makes a bigger difference than upgrading to triple glazing for thermal reasons alone.
USEFUL TO KNOW
Condensation on the inside of the glass is a ventilation/humidity issue in the room, not a window fault. Condensation between the panes means the sealed unit has failed. Condensation on the outside (on a cold morning) is actually a sign of a well-insulated window, not a problem.
WORTH KNOWING
The spacer bar between glazing panes affects both thermal performance and condensation risk at the edge of the glass — modern "warm edge" spacers perform better than older aluminium spacer bars. Worth asking which type is specified, particularly for a north-facing or otherwise cold room.
LOCAL GUIDE
Bexley is a large town in the London region under Greater London administration, using the DA5 postcode district. No population number is given in the supplied data. Being part of Greater London means local planning, building control and waste services are managed at borough level. The DA5 postcode is helpful when comparing trades because it restricts results to contractors who operate in that outer‑London area and who understand DA5 access, travel times and local regulations. For homeowners, a large‑town tier in this part of London typically includes a variety of property ages and sizes; expect trades to be accustomed to suburban working conditions, to arranging vans and deliveries, and to advising on whether any borough consents or parking suspensions are needed for external projects.
In Bexley the variety of property ages means window specialists need to handle both timber sash conservation and modern uPVC or aluminium replacement frames. Borough-level planning and building-control oversight affects conservation areas and visible elevations, so installers should be ready to advise on whether traditional-style frames or specific finishes are required. From a compliance perspective, competent installers are typically registered with FENSA or CERTASS which lets them self-certify Building Regulations for replacements; that registration gives homeowners confidence about thermal performance and safety standards.
Older sash-window properties may need timber-specific repair and draught-proofing skills, while newer builds are more likely to require double or triple glazing and upgraded thresholds or patio doors. When hiring, request evidence of FENSA/CERTASS registration, examples of work on properties of a similar era, and a written specification noting materials, U‑values and any permissions needed for work in conservation settings. Also agree how installers will manage deliveries and protect internal floors during removal and fitting.
