New Window Handles: White vs Black vs Chrome Finishes

Replacing old or damaged window handles is an effective way to refresh windows, improve security and restore smooth operation. This guide covers how to choose the right new window handles, compatibility with common mechanisms, and step-by-step fitting advice for uPVC, timber and aluminium frames.

Why replace window handles?

New window handles can:

Restore smooth operation when handles are stiff or loose.

Improve security by upgrading to better lock cylinders or thumb turns.

Refresh the look of windows without replacing the whole frame.

Ensure compatibility with new hardware such as espagnolette mechanisms or top-hung hinges.

The keyword to remember is new window handles: choosing correctly means matching style, mechanism and security needs.

Types of window handles and where they fit

Espag and offset handles

Espag handles are common on uPVC and aluminium casement windows. If your window uses an espagnolette lock, choose an appropriate offset or slimline handle to match the spindle location. Examples include the Avocet Slimline Offset Window Espag and TSS Offset UPVC Window Handles.

Practical tip: measure the distance from the handle centre to the spindle axis and check whether you need a left or right hand version.

Cockspur handles

Cockspur handles (or cockspur fasteners) are surface-mounted and common on older or simpler uPVC and metal frames. They are easy to fit and replace; see TSS Cockspur Window Handles.

Thumb turn and euro cylinder handles

If your windows use a euro cylinder lock, you can fit a thumb turn cylinder for easy internal locking. The TL Thumb Turn Euro Cylinder and high-security options such as the Ultion Plus TS007 3* Kitemarked Euro Key & Turn Cylinder are relevant here.

Specialist handles for top-hung and in-line mechanisms

Top-hung windows use different hinge geometry; ensure the handle is compatible with the Top-Hung Window Hinge - Standard or an in-line mechanism such as the In-Line Window Mechanism.

Materials, finish and durability

Common materials for new window handles:

Zinc alloy: cost effective and widely used.

Aluminium: lightweight, corrosion resistant.

Stainless steel: robust and long lasting for coastal locations.

Finishes matter for matching existing furniture: white, black, chrome, satin or brass. For external exposure choose corrosion-resistant options or stainless steel such as the Flag Door Hinge - Stainless Steel for matching hardware.

Practical tip: if the window sits in a humid or coastal area, avoid plated finishes that may peel; select stainless steel or high-quality powder coating.

Security considerations

When fitting new window handles, consider how they interact with the locking system. A handle alone does not provide cylinder protection; combine it with a secure euro cylinder or thumb turn where appropriate.

Use kitemarked cylinders (TS007 3 where possible) for improved break-in resistance: Ultion Plus TS007 3 Kitemarked Euro Key & Turn Cylinder.

Fit internal restrictors or limiters for top-hung windows to prevent full opening from the outside.

Practical tip: if you replace a handle that operates an espagnolette, ensure the locking rods and shootbolts engage fully. Loose or worn gaskets such as B003 Bubble Gasket and B004 Bubble Gasket may also affect security and sealing.

Compatibility checklist before buying

Identify the lock type: espagnolette, cockspur, or euro cylinder.

Measure backset and spindle size: common spindle sizes are 7mm or 8mm square.

Check screw hole centres: match to holes in the existing handle or be prepared to fill and re-drill.

Determine left or right hand orientation when the window is closed.

Verify handle length and clearance for trims and tiles.

Practical tip: take a photo of the existing handle, including measurements, and bring it to the supplier or compare with product pages such as Avocet Slimline Offset or TSS Offset options.

Tools and parts you may need

Crosshead and flat head screwdrivers.

Allen keys (common for spindle fixing screws).

Replacement spindle (if damaged) and new fixing screws.

New cylinder or thumb-turn if upgrading security: TL Thumb Turn or Ultion Plus TS007.

Silicone or sealant if holes need filling.

If the mechanism is worn, consider replacing associated parts: espagnolette mechanism, in-line mechanisms (/p/inline-window-mechanism) or hinges (/p/top-hung-hinge-standard).

Step-by-step: fitting new window handles (uPVC/espag example)

Open the window and support it in the open position.

Remove the handle: unscrew the fixing screws and pull the handle off the spindle.

Inspect the spindle and mechanism: if the spindle is bent or worn replace it.

Compare new handle spindle size and orientation; insert the spindle into the lock mechanism.

Place the handle onto the spindle and align fixing holes; tighten screws snugly but do not over-torque fixing screws which can strip uPVC.

Test operation: open and close the window several times to ensure the handle operates the espagnolette correctly and that the window locks fully.

Fit new cylinder or thumb turn if upgrading: follow manufacturer instructions for euro cylinders.

Practical tip: if the handle feels loose after fitting, check that the screw holes in the frame are not stripped; use a longer screw into a solid part of the frame if necessary, or use a plastic rawlplug designed for uPVC.

Common problems and fixes

Handle spins with no operation: spindle may not engage the mechanism. Check spindle length and position; replace spindle if worn.

Handle stiff to operate: clean and lubricate the mechanism with a dry lubricant; replace rubber gaskets (B003 or B004) if they impede movement.

Misaligned locking: adjust the keeps on the frame or realign the espagnolette rods.

When to call a professional

Call a window specialist if:

The sash is heavy or the mechanism is seized and you cannot move it safely.

You suspect the espagnolette mechanism or hinges are failing; they may need replacement (/p/inline-window-mechanism, /p/top-hung-hinge-standard).

You are upgrading to a high security cylinder and require correct alignment and fitting to achieve the rated protection.

Final checks and maintenance

Test each window three times after fitting new window handles.

Lubricate moving parts annually with a suitable dry lubricant.

Check fixings and seals; replace bubble gaskets (B003 or B004) if weatherproofing is compromised.

Replacing new window handles is a relatively straightforward way to improve function, security and appearance. With the right measurements, a compatible handle such as an espag, cockspur or thumb-turn option, and basic tools you can complete most jobs yourself. Where mechanisms or frame fixings are damaged, consider replacing the relevant parts or calling a professional.
