WINDOW INSIGHTS
Practical information for planning the job, working out costs and choosing a good Window Specialist.
GOOD TO KNOW
Cost depends on frame material, glazing type (double vs triple), the number and size of openings, and whether it's a like-for-like replacement or involves altering the opening size. Bay windows and bifold doors cost more than standard casement windows of the same total area.
WORTH KNOWING
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.
GOOD TO KNOW
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.
WORTH KNOWING
In a leasehold flat, window replacement sometimes needs freeholder or management company permission, particularly if it affects the building's external appearance — check your lease before booking work, not after ordering.
INSURANCE & COVER
Insurers sometimes ask about window and door security ratings (multi-point locking, PAS 24) when assessing a burglary claim or offering a premium. Keep any certificates and product specifications from an installation in case they're needed to support a claim later.
WORTH KNOWING
Trickle vents are the small vents built into a window frame that provide background ventilation without opening the window — increasingly required by Building Regulations on replacement windows to manage condensation and indoor air quality, particularly in well-sealed modern homes.
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
A misted glazing unit can sometimes be replaced on its own within the existing frame, which is cheaper and faster than a full window replacement — worth asking specifically if the frame itself is otherwise in good condition, rather than assuming the whole window needs replacing.
LOCAL AREA
Putney is a large town area in Greater London, in the London region and covered by the SW15 postcode district. No population is listed, but as a large town it represents a busy residential and commercial district within southwest London. Local planning, waste and highways are provided by the relevant London borough and follow Greater London policy frameworks. For trades searches SW15 narrows contractors to those familiar with Putney’s riverside and suburban mix. Homeowners can expect jobs ranging from period‑property maintenance and sash‑window repair to modern flat refurbishments and external weatherproofing given proximity to the Thames. Central‑London restrictions are less severe than inner zones, but parking and access for larger vehicles still require planning for many projects.
Window projects in Putney cover period sash restoration, timber repairs and modern double or triple‑glazing installations for flats and houses in SW15. FENSA or CERTASS registration allows installers to self‑certify Building Regulations compliance, a helpful convenience for homeowners needing paperwork for transactions or insurance.
Conservation considerations do exist in some Putney streets, so timber specialists who can restore or replicate sash windows may be required for period properties. For riverside locations, attention to seals and drainage detail helps reduce moisture ingress and improve longevity. When engaging installers, request FENSA/CERTASS certification, thermal performance figures (U‑values) and examples of sash or timber work if your property retains original joinery.
