8 Warning Signs Your Fulham Windows Need Professional Attention

Timber windows in London's period properties give plenty of warning before problems become serious. Catch these early and maintenance costs a fraction of replacement.

💨

Cold Draughts

Feel cold air around closed windows? Worn weather seals or failed draught-proofing — easily fixed.

🔊

Rattling in Wind

Rattling sashes indicate loose-fitting frames. Draught-proofing eliminates this and reduces road noise significantly.

🪤

Sticking or Jamming

Windows that won't open or close smoothly — usually paint build-up or swollen timber. Solved in a single visit.

🪨

Sash Won't Stay Up

A sash that falls when released means broken sash cords or failed balances. A straightforward repair by our joiners.

🍂

Soft or Spongy Timber

Press the frame with a finger — if it gives, rot has set in. Early-stage rot can be consolidated rather than replaced.

💧

Condensation Between Panes

Misting inside double-glazed units means the seal has failed. We replace the glazing unit, not the whole window.

🎨

Peeling or Flaking Paint

Bare timber exposed to London weather deteriorates fast. Repainting as preventive maintenance costs far less than repairs later.

🔒

Broken or Stiff Locks

Failed window locks are a security risk. We replace hardware quickly with high-quality fittings in your preferred finish.

When to Maintain Your Windows — and When to Replace Them

We will always give you an honest assessment. In many cases — particularly for original Victorian and Edwardian sash windows in Fulham's period properties — maintenance and repair delivers better long-term value than replacement.

We recommend maintenance when:

  • The box frame is structurally sound with no major rot
  • The profiles are original and worth preserving — particularly in conservation areas
  • The property is listed and like-for-like replacement would require planning consent
  • The windows have sentimental or architectural significance
  • Budget constraints make phased improvement preferable to full replacement

We recommend replacement when:

  • Rot has spread through the box frame and sill beyond economic repair
  • The window has been previously bodged with non-traditional materials
  • Single glazing combined with poor thermal performance makes the whole unit inefficient
  • Security has been irreparably compromised

Not sure? We'll visit, assess and give you an honest written recommendation — at no charge.

Window Maintenance Fulham — Frequently Asked Questions

How much does sash window maintenance cost in Fulham?
Costs vary depending on what's needed. A draught-proofing service typically costs £150–£350 per window. Sash cord replacement is usually £80–£150 per window. A full overhaul — combining draught-proofing, cord replacement, hardware and repainting — typically ranges from £300–£600 per window. Contact us for a free, no-obligation written quote specific to your property.
Is it worth repairing sash windows or should I replace them?
In most cases for Fulham's Victorian and Edwardian properties, repair and maintenance delivers better long-term value than replacement — particularly where the original box frames are structurally sound. Original sash windows have deep proportions and profiles that are difficult to replicate exactly in replacement units. We'll give you an honest written assessment after our free survey.
Can you draught-proof sash windows in a Fulham conservation area?
Yes. Draught-proofing sash windows is fully permitted in all conservation areas — it does not alter the external appearance of the window and no planning permission is required. This makes it one of the most practical and cost-effective improvements available to homeowners in Fulham's many conservation areas.
How long does a sash window maintenance visit take?
Most maintenance visits are completed in a single day. A full overhaul of 4–6 windows typically takes one working day. Larger properties or more complex repairs may require two days. We'll agree a clear schedule with you before we start.
Do you repair casement windows as well as sash windows?
Yes. We maintain and repair all types of timber windows — sash windows, casement windows, bay windows, fanlight windows and more. Our services include hinge replacement, handle and lock upgrades, glazing replacement, draught-proofing and timber repairs for all window types.
Can you replace just the broken glass in my sash window?
Yes. We replace individual broken panes — single glazed, double glazed or decorative glass — without disturbing the surrounding frame. Period glass, obscure glass and acoustic glass are all available. Emergency glass replacement is offered across Fulham and SW London.
Do you offer a guarantee on window maintenance work?
Yes. All A&J Joinery window maintenance and repair work comes with a 5-year written workmanship guarantee. If any issue arises with work we have carried out within that period, we will return and rectify it at no charge.
