Window Parts and Components

Window parts and components keep your uPVC windows functioning smoothly and securely. At Window Repairs Sutton, we specialise in sourcing and fitting replacement window parts for common issues in uPVC window parts. Whether it’s hinges, handles or seals, understanding these elements helps you identify problems early.

What It Is

Window parts and components are the individual elements that make up a uPVC window system. These include window parts like friction stays, handles, locking mechanisms, sealed glazing units and draught excluders.

Each plays a vital role: friction stays support opening and closing, handles provide control, locks ensure security, sealed units maintain insulation, and weatherseals prevent air leaks.

We focus on standard casement uPVC windows, stocking uPVC window parts compatible with most local installations in Sutton.

How To Identify It

Spotting faulty window parts starts with visual and functional checks. Look for visible wear such as rust, cracks or misalignment on moving window parts.

  • Friction stays: Check for sagging or stiff operation – explore our guide on friction stays.
  • Window hinges: Often confused with stays; identify by pivot points – see window hinges.
  • Window handles: Loose or spinning espagnolette-style handles signal issues – details at window handles.

Test locks for smooth engagement and seals for gaps. If unsure, note the symptoms and contact us for advice.

Compatibility Factors

Not all replacement window parts fit every window. Key factors include frame material (we handle uPVC only), window style (casement focus, excluding sash, sliding or tilt-and-turn) and bevelled edge profiles.

Colour matching is crucial – white, woodgrain or anthracite are common. Manufacturer variations like Maco, Avocet or Era affect lock compatibility.

Measure your existing part first. Our window locking mechanisms page covers specific fits, and sealed units double glazing details glazing matches.

Measurements That Matter

Accurate measurements prevent mismatches in window parts and components. Use a tape measure for length, width and depth in millimetres.

  • Friction stays and hinges: Arm length (typically 300-450mm) and stack height.
  • Handles: Spindle length (usually 20-40mm) and screw centres (40-43mm).
  • Locking mechanisms: Overall length (500-2500mm), spindle positions and hook distances.
  • Sealed units: Exact glass dimensions, including rebate depth (20-30mm).
  • Draught excluders: Perimeter lengths matching frame sizes.

Record handedness (left/right) for stays and handles. Our draught excluders weatherseals guide includes sizing tips.

Common Naming Confusion

Window parts often have overlapping names, leading to mix-ups. Friction stays are commonly called “hinges,” but true hinges are side-mounted pivots – compare at window hinges vs friction stays.

“Espagnolette locks” refer to multi-point window locking mechanisms, not simple handles. Sealed units are the double-glazed panels, distinct from frames.

Weatherseals are draught excluders, not rubber glazing seals. Clarifying these avoids ordering errors – check our specific pages for visuals.

Symptoms It Can Cause

Worn uPVC window parts trigger clear issues. Draughts often stem from perished draught excluders weatherseals, letting cold air in.

FAQs

What are the most common window parts that need replacing?

Window parts like friction stays, handles, locks and seals wear out fastest due to daily use. Sealed units fail from seal breakdown. See our hub at /parts/.

How do I know if my window parts are compatible?

Check frame type, measurements and brand. uPVC casements match most replacement window parts we supply – use our guides like window locking mechanisms.

Can you repair windows without full part replacement?

Often yes, via adjustment or cleaning, but worn uPVC window parts usually need swapping. View repairs options.

Do you handle measurements for me?

We recommend customer measurements first, then verify on-site. Key sizes for sealed units double glazing include glass dimensions.

What if my window handle spins but doesn’t operate?

Likely spindle wear in window handles. Simple to replace – contact us for stock check.

Are your parts suitable for older uPVC windows?

Many window parts and components are universal for post-2000 uPVC, but pre-1990s may vary. Confirm via photos when enquiring.

How long do window seals last?

Draught excluders typically 10-15 years, depending on exposure. Replace proactively – details at draught excluders weatherseals.
