If you run a business in the capital, your exterior presentation dictates your foot traffic. Golden Ratio Windows operates as Shop Front Installers London, manufacturing custom wooden storefronts entirely from scratch. You cannot buy a modular storefront off a shelf and expect it to fit a historic Victorian brick opening — the building structures across the capital are warped and settled. Our carpenters build the timber frames to match the exact irregularities of your specific commercial property.
Standard softwood frames rot quickly when exposed to continuous rain and street-level pollution. We use Accoya or Sapele timber for all commercial installations. Accoya is a modified wood that resists shrinking and swelling, so your shop doors won't stick during the winter months. Sapele is a dense hardwood that provides exceptional structural strength for large window spans — heavy glass units require massive timber mullions and transoms to hold the weight without bowing. As experienced Shop Front Installers London, we understand how to distribute this weight correctly across the structural opening.
Planning permission is a significant hurdle for any commercial renovation. Local councils actively reject designs that disrupt the historical continuity of the street. If your property sits in a conservation area, you must replicate traditional pilasters, corbels, and stallrisers. We replicate these exact architectural details in our joinery workshop, studying neighbouring buildings and matching the moulding profiles exactly. This prevents costly council rejections and keeps your opening schedule on track.
A storefront must protect your inventory through the night, and standard residential locks don't provide adequate commercial security. We integrate high-security hardware directly into the traditional timber frames — morticing heavy-duty deadlocks into the solid Sapele stiles.
We install thick laminated safety glass instead of standard toughened panes. Laminated glass holds together when struck with heavy force, preventing smash-and-grab burglaries.
The logistics of fitting commercial joinery in central locations require military precision. Red-route parking restrictions and narrow pavements make unloading materials extremely difficult. We manage all local authority permits and arrange specialised lifting equipment for the heavy glazing units. The installation process involves stripping away the old metal or cheap plastic cladding — and we frequently discover rotten lintels hidden behind the old fascias, which we replace and reinforce before hanging the new timber frames.
We work efficiently to minimise your trading downtime. The entire storefront is fabricated and painted in our workshop prior to delivery, so the onsite work is strictly limited to structural fitting and weatherproofing. We seal the frames with high-grade mastics to prevent water ingress and draft penetration — a poorly sealed storefront will ruin your interior flooring and drive up your heating bills. Hire professional Shop Front Installers London and you receive a watertight, secure, and visually striking entrance that attracts customers and protects your livelihood.
We don't provide estimated quotes over the phone, because every commercial property is unique. We conduct comprehensive site surveys to measure the exact dimensions and assess the structural integrity of the existing masonry. This allows us to provide a fixed, accurate cost for the entire project — no surprises once work begins.
