GB DIY Store

GB DIY Store, a specialist supplier of uPVC window and door spares

GB DIY Store is a family-run company based in the United Kingdom that sells replacement hardware and repair parts for uPVC windows and doors. Its catalogue covers window handles, hinges, lock mechanisms, door handles, cylinders, multipoint locks and gasket seals, alongside tools, sealants and plastic components. The company states that it holds more than 2,500 products in stock across these repair categories.

The business describes itself as having started out manufacturing and installing windows and doors before moving into repairs, and its team reports over 25 years of experience in the sector. That background underpins the range of spares it now offers for maintenance, repair and upgrade work.

Parts for windows

The window hardware section is organised by component type. It includes espag, cockspur and tilt-and-turn window handles, window keys, uPVC window hinges, window restrictors, espag locking mechanisms, window lock gearboxes and window keeps. Ventilation products such as trickle vents and in-glass ventilators are also listed, together with hardware for vertical sliding sash windows.

Door hardware and locking

For doors, the range covers uPVC, patio and bifold door handles, letterboxes, door knockers, uPVC and composite door hinges, uPVC and French door restrictors and patio door wheels. The locks section brings together key cutting for ABS/Avocet, Federal Lock, Shield Hardware and Yale keys, euro cylinders, multipoint lock gearboxes, full multipoint door locks, latches and keeps, padlocks and additional locks and restrictors.

Seals, tools and plastics

Window and door seals are grouped into bubble gasket, bifold door gasket and wedge gasket types. Under tools and supplies the store lists hand tools, drill bits, screws, sealants and glues, glazing tape, uPVC repair pens, cleaning supplies, glazing packers and cable management. The plastics category includes uPVC door panels, uPVC trim, gutter brackets and plastic accessories.

Brands stocked

The site names Yale, Versa and Lockmaster among the manufacturers it sources from, and its brand listing also includes Avocet, Federal Lock, SHIELD HARDWARE, ERA, GU, Trojan and Fullex.

Identifying the right part

Because replacement parts vary between systems, the store offers help for customers who cannot identify a component: they can send a photo and a few details to the team, which will assist in matching a uPVC window or door handle, lock, gearbox or other spare. The website also publishes measuring and fitting guides, including a multipoint door lock gearbox identification guide, a uPVC door handle finder and separate guides for cockspur and espag window handles, lever/lever uPVC door handles, window and door gasket seals and euro cylinders.

Ordering and trade customers

Orders placed before 3pm Monday to Friday are despatched the same day, according to the company. All prices shown include VAT, and a trade account option is available alongside the standard retail checkout. The site also maintains a blog with practical articles on subjects such as identifying uPVC door hinge types and measuring window hinges and friction stays.
