WINDOW KNOW-HOW
What you need to know to plan ahead, budget properly and hire the right Window Specialist.
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.
USEFUL 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.
QUALITY & GUARANTEES
Frame guarantees commonly run 10 years, glazing unit guarantees are often shorter — ask specifically, since a failed seal (misting between panes) is a glazing unit issue, not a frame issue, and needs to be covered by the right guarantee. Installation workmanship guarantees are usually separate again.
GOOD TO KNOW
Listed building consent is usually required to replace windows in a listed property, and uPVC replacements are often refused — timber matching the original profile is typically required instead. Conservation areas have similar restrictions even where the property isn't individually listed. Check with your local planning authority before ordering anything.
GOOD TO KNOW
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.
WORTH KNOWING
Original timber windows in reasonable structural condition can often be restored — new sash cords, draught-proofing, re-glazing with slimline double glazing units designed for period frames — at lower cost and disruption than full replacement, and is sometimes the only option allowed on listed properties.
GOOD TO KNOW
Toughened (safety) glass is required by Building Regulations in doors and low-level windows. Laminated glass adds security and noise reduction. Obscure (patterned) glass is used where privacy matters, like bathroom windows, without losing light — worth specifying which you need per opening rather than assuming standard clear glass throughout.
GOOD TO KNOW
uPVC is the most common choice for cost and low maintenance. Timber suits period and listed properties but needs repainting or resealing every few years. Aluminium is slimmer-profiled and suits larger glazed areas or a more modern look, typically costing more than uPVC for the same size.
LOCAL AREA
Horley appears in Surrey in the south‑east and uses the RH6 postcode district. No local population is provided here, and the town will be served by Surrey’s local authority structures for planning, roads and other services. For trade searches the RH6 postcode connects you with contractors familiar with the Surrey and Gatwick corridor. Towns of this size usually have good access for vans and plant, though proximity to airports or busy transport corridors can affect delivery windows and traffic; specify site access and any timing constraints when requesting quotes, and check with the local authority about permits for larger scaffolding or road‑occupancy works.
In Horley’s RH6 catchment you’ll find a blend of older suburban houses and newer developments, so window specialists here frequently replace timber sashes in period properties and install uPVC or aluminium units in modern homes and extensions. Conservation concerns for older façades may mean timber or heritage‑style frames are preferred, while newer builds or loft extensions often suit slim aluminium or uPVC frames and triple glazing. Installers who are FENSA or CERTASS registered can self-certify compliance with Building Regulations, which simplifies the process and provides documentation you’ll need for future sales or insurance.
Because window deliveries and installation often require van access and space for glazing, contractors in this corridor will ask about site access and any restrictions on parking or unloading; busy transport routes near Gatwick can affect delivery slots. Where sash-window repairs are needed, timber specialists will be able to match profiles and carry out draught-proofing and sash cord replacement to retain character. When ordering windows in Horley, ask for registration details (FENSA/CERTASS), examples of similar work in the area and a clear specification that confirms frame material, U‑values and whether installation includes Building Regulations sign-off. Also check the lead time for bespoke timber units if your property requires period-accurate replacement.
