What Gowercroft Joinery does

Gowercroft Joinery (legal entity Gowercroft Limited) is a privately held UK manufacturer and installer of premium timber windows and doors, founded in 1998 and operating from a single workshop in Alfreton, Derbyshire. The company designs, manufactures, hand-finishes, and installs all products through its own teams, organised around three tiers: a Classic Range of double and triple-glazed windows/doors for unlisted and new-build properties; an award-winning Heritage Range built around an 8.3mm LandVac vacuum glazing unit for listed buildings and conservation areas; and a Performance (Frontier) Range engineered to Passiv-Haus standard using FSC-Certified Accoya with a proprietary triple-glazed vacuum cavity unit and an adapted Italian paint system. Patented SashSealer technology underpins the sliding sash range, delivering a Class 4 Air Permeability rating that the company claims is unique for traditional sliding sash windows.

The business operates a direct-to-customer go-to-market with no dealer or distributor layer: its own surveyors carry out site visits nationally and its own fitters install all products. Customers comprise three segments — architects/specifiers, construction professionals, and homeowners — served across residential, heritage, and commercial projects including notable commissions at Templeton House, Saltdean Lido (Grade II*), Riber Castle, The Waterman Building in Farringdon, and Tomlinson Homes' Old Rectory conversion in Clifton. Revenue is generated primarily through one-off bespoke product sales plus installation services, with a recurring-revenue layer from the optional TimbaCare lifetime maintenance programme and a 10-year no-quibble guarantee underwritten by Home Improvement Protection (HIP). Reported quality metrics include a 99.5% Right First Time rate, fewer than five warranty claims in the past year, and over 80% of enquiries originating from repeat customers or referrals.
