WINDOW BASICS
Advice to help you get organised, understand what things cost and find a reliable Window Specialist.
GOOD TO KNOW
Modern replacement windows and doors use multi-point locking as standard, and some are tested to PAS 24 security standards — worth asking about specifically if security is a priority, since not every installer fits PAS 24-rated hardware by default even on similar-looking frames.
GOOD TO KNOW
Fitting itself is typically one day per 4-6 windows once the made-to-measure units arrive (the survey-to-fitting lead time, 2-6 weeks, is usually the longer wait). A full house re-glaze commonly takes 1-3 days of on-site work.
WORTH KNOWING
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.
WORTH KNOWING
Bifold doors fold back concertina-style for a fully open aperture, good for maximising opening width. Sliding doors have a smaller usable opening (roughly half the total width) but a slimmer profile and often lower cost. The right choice usually depends on how the opening will actually be used, not just the look.
SAFETY & COMPLIANCE
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
If the frame and seals are otherwise sound, draught-proofing strips and secondary glazing can meaningfully cut draughts without full replacement — worth considering before committing to new windows, particularly on a period property where replacement is restricted anyway.
REGULATIONS & SAFETY
Part L sets minimum energy efficiency standards for replacement windows and doors — a maximum U-value the glazing must meet. A FENSA or CERTASS registered installer certifies this automatically as part of the job; an unregistered installer means arranging a separate council building control inspection and paying its fee yourself.
WORTH KNOWING
Timber sash and casement windows on period properties can often be draught-proofed and restored rather than replaced, which is sometimes required for listed properties anyway and can be more cost-effective than full replacement if the frames are structurally sound.
ABOUT THIS AREA
Richmond upon Thames is a large town-area within Greater London and the London region, using the TW9 postcode district. No specific population is given here, but as a large town it forms an important residential and commercial hub within southwest London. Local services such as planning, conservation and highways are administered by the Richmond upon Thames borough under Greater London policy. Using TW9 in trades searches helps identify contractors experienced with riverside properties, conservation areas and higher‑value suburban homes. Property work in Richmond commonly involves sensitive repairs and restorations where historic facades must be preserved, external timber and masonry maintenance, and interior upgrades that respect listed‑building constraints. Tradespeople should be prepared to work within stricter conservation and parking controls than in non‑central suburbs.
In Richmond upon Thames, where preservation of historic facades is commonly required, window work frequently involves bespoke timber sash repairs or carefully specified replacements that respect conservation area criteria. Installers experienced in TW9 should be able to advise whether timber, aluminium or sympathetic heritage‑style alternatives are appropriate and provide FENSA or CERTASS registration for Building Regulations compliance on thermal and ventilation performance.
Older sash properties often require timber‑specific expertise to repair existing frames and draught seals rather than wholesale replacement, which helps retain character and may avoid listed‑building consent. When assessing installers, ask for proof of FENSA/CERTASS membership, examples of sash work executed to conservation standards, and a proposal showing how the new frames will match sightlines and profiles. Expect trades to outline any need for pre‑application discussions with the borough’s conservation officers for visible alterations.
