Choosing the right tool or fixing can make the difference between a clean repair and damaged hardware. Check sizes, materials and the individual product specification before ordering.

Glazing Tools for Window & Door Repairs
Our glazing tools cover the jobs involved in removing, measuring, handling and refitting glass and glazing beads. The range includes nylon-faced glazing hammers, glazing paddles and shovels, bead-removal chisels, gasket and mitre shears, glass cutters, sealed-unit thickness gauges, suction lifters and useful glazing tool bundles.
A nylon-faced hammer is preferred when tapping glazing beads back into position because the replaceable non-metal faces reduce the risk of marking the workpiece. Glazing paddles are used for positioning sealed units and assisting with toe-and-heeling, while glass thickness gauges can help measure an installed sealed unit before a replacement is ordered.
Glazing Packers & Wedges
Glazing packers are used to support, space and position glass units and frames. JCP flat plastic packers are available in different thicknesses for levelling and toe-and-heeling windows and doors, while wedge packers can be useful for frame installation and general spacing work.
Choose the packer thickness to suit the job rather than forcing a glass unit or frame into position. Correct packer placement is particularly important when toe-and-heeling a door or window sash because the packers help transfer the weight of the glass back into the frame.
Fixings, Screws & Bolts
Our fixings, screws and bolts include products for replacement window and door hardware as well as frame installation and coupling. Depending on the job you will find items such as M5 window-handle screws, friction-hinge fixings, self-drilling uPVC screws, frame anchors, Torx masonry fixings and baypole/frame coupling screws.
Before ordering, check the diameter, length, head or drive type and the material being fixed into. A screw that fits through the hardware is not necessarily the correct fixing for the frame or substrate behind it.
uPVC Door & Window Repair Products
Minor cosmetic damage does not always mean replacing an otherwise serviceable frame, sash or panel. Our door and window repair range includes touch-up and scratch-repair products for light marks, chips and surface damage on selected uPVC, foiled, coloured and woodgrain finishes.
Always match the repair product to the colour and surface finish. Scratch pens are best suited to small superficial marks, while deeper chips or dents may need a filler or hard-wax repair system. These products are intended for cosmetic repairs and should not be used to disguise structural cracks or damaged components that need replacement.
Sealants & Adhesives
Our sealants and adhesives include silicone sealants, bonding products, expanding foam and application tools. Products such as Bond It HA6 are specialist high-movement marine-grade silicones with defined substrate and application requirements, so one sealant should not be treated as suitable for every job.
Before choosing a sealant or adhesive, check the surfaces being joined, whether the application is internal or external, the movement required in the joint and any manufacturer limitations. Clean, dry and correctly prepared surfaces are essential for reliable adhesion.
Cleaning, Security & General Tools
Cleaning products are useful for preparing surfaces and cleaning up after installation and repair work. Our range includes workshop and glazing consumables such as large two-ply cleaning rolls for wiping frames, glass and general work areas.
Padlocks and hasps cover practical security for sheds, gates, lockers, toolboxes and other applications. Check the shackle size, opening, intended environment and security level rather than choosing by body size alone.
For the smaller jobs around fitting and maintenance, browse our general tools and accessories for useful items that support window, door and glazing work.
Frequently Asked Questions
Why use a nylon glazing hammer instead of a normal steel hammer?
Nylon-faced glazing hammers are designed to strike glazing beads and similar components without presenting a hard steel face directly to the workpiece. The Thor nylon hammers stocked by JCP use replaceable moulded faces with no metal inserts in the face, helping reduce the risk of marking the bead when used correctly.
What are glazing packers used for?
Glazing packers support and position sealed glass units within a frame. They are also used when toe-and-heeling door and window sashes, levelling frames and creating controlled spacing during installation. The required thickness and position depend on the particular frame and glazing arrangement.
Can I measure a double-glazed unit without removing it?
Specialist glass-thickness gauges can measure many sealed units while they remain in the frame. This can save unnecessary deglazing and helps confirm the unit thickness before ordering a replacement. Check the measuring range and access required for the gauge you choose.
Which screw do I need for a replacement window or door part?
Use the original fixing as a reference where possible and check its thread or diameter, overall length and head type. For example, many espag window handles use M5 machine screws, but the required length varies with the handle and frame. Do not assume that one screw size fits every handle, hinge or lock.
Can a uPVC scratch repair product fix a cracked frame?
No. Touch-up pens, fillers and hard-wax kits are intended for cosmetic surface damage. A cracked, distorted or structurally damaged frame, sash or door component should be assessed and repaired appropriately rather than covered with a cosmetic product.
How do I choose the right silicone or adhesive?
Start with the application and substrate. Check whether the product is approved for the surfaces being bonded or sealed, whether it will be exposed to weather or movement, its curing requirements and any limitations in the technical information. If the manufacturer does not list your intended use, do not assume compatibility.
