Working With SIVAL in Surrey
From Esher and Weybridge's private estates to contemporary self-builds in the Surrey Hills, this county leads our premium order book. The SV-3600 Minimal slider — sashes up to a tonne, sightlines of 26mm, optional concealed motorisation — was practically made for Surrey's glass-walled living rooms, and the SV-7800 Porta Prime entrance door provides the statement frontage to match.
Architects and main contractors here get the full engineering service: project-specific U-value reports for Part L submissions, structural calculations for oversized openings, sample finishes for planning boards, and coordination between glazing, balustrade and shading packages so everything arrives finished to match.
For renovations in Guildford, Farnham and the commuter towns, whole-house window replacement with the SV-6800 Thermo remains the everyday workhorse — warmer, quieter and slimmer than the uPVC it usually replaces, in any RAL colour with a 25-year finish guarantee.
We cover the whole county — Guildford, Woking, Esher, Weybridge, Farnham, Dorking, Reigate, Epsom and the villages of the Surrey Hills — through installation partners who specialise in high-specification residential work.
Large-format glass (single panes beyond roughly 6m² or 350kg) needs crane or vacuum-lifter access; our partners plan this at survey, and it's worth flagging steep drives or tight lanes when you first enquire.
Architect-led projects can contact our technical team directly for NBS-style specifications, CAD sections and thermal modelling before tender.
