Maintenance & Warranty Requirements

(Aligned with Kingswood Joinery UK Ltd Terms & Conditions)

Kingswood Joinery UK Ltd provides a 5-year warranty on all timber windows and doors supplied and/or installed.

  • Cleaning of frames, glass and drainage points.
  • Lubrication of moving parts (hinges, locks, pulleys) using a suitable light oil.
  • Light adjustments to hardware, if required.
  • Checking paint or finish for chips, cracks or water ingress.

Maintenance must be documented with dated photos or receipts, and evidence may be requested when processing a warranty claim.

2. Paint & Coating Care

  • External timber products must be redecorated as required, depending on exposure.
  • High-exposure environments (coastal, south-facing or high-humidity areas) may need more frequent redecoration.
  • Bare timber must never be exposed, any coating failure must be repaired promptly.
  • Redecoration carried out by third-party contractors may require proof of work when making a claim.

3. Weather Seals & Sash Components

  • Draught seals must remain clean, correctly seated and not painted over.
  • Sash cords and pulleys must be checked periodically for smooth operation.
  • Wear-and-tear components are not covered by the warranty and must be replaced by the customer.

5. Glazing & Misted Units

If misting occurs within the warranty period:

  • If the cause is a product or manufacturing defect, a replacement will be arranged.
  • If not, survey and visit fees will apply (including any wasted day rate and travel/access costs).

6. Storage & Handling Before Installation

Swelling or coating failure caused by humidity is not a warranty issue.

  • Repairs are attempted by others without written approval.

9. Investigation of Faults

  • Misuse

  • Environmental conditions
  • Builder/trade interference

→ The customer will be liable for:

  • Call-out fees
  • Wasted day rates
  • Costs of repair or replacement (paid upfront)
