Repair and Restore Wooden Windows, Do Not Rip Them Out

Timber window restoration is the careful repair and refurbishment of old wooden windows instead of tearing them out for modern plastic replacements. We treat the existing wood, splice in new timber where sections have decayed, upgrade the glazing seals and putty, and keep the original detail that gives a period home its character. It is part of our wider windows and glazing service across Uxbridge, Harefield and the surrounding villages.

Every job starts with a free on-site visit to check for hidden rot, failed putty and movement in the joints, followed by an honest, itemised quote. If a window is genuinely beyond repair we will say so, and our new window installation service can take over. If a pane is only cracked or misted, see broken window repair instead.

Our Timber Window Repair & Restoration Services

From a single spliced sill to a full house of restored sashes, we have an option to suit your windows and your budget.

Rotted & Damaged Timber Repair

We cut out only the decayed sections and splice in treated timber to match the existing frame, far cheaper than a full replacement.

Frame Strengthening & Refurbishment

Weak, sagging or loose frames reinforced with repaired joints and epoxy resin systems, so the window is solid again.

Sash Window Repairs

Broken sash cords replaced, weights rebalanced, pulleys serviced and draught-proofing added so box sashes glide and seal.

Putty Reglazing & Repainting

Failed putty raked out and replaced with traditional linseed putty, then sanded, primed and finished in microporous paint.

Benefits of Restoring Your Timber Windows

Repair keeps the character, costs less than replacement and can add another lifetime to the window.

Keeps Your Home's Character

Original wooden window designs add charm and authenticity that a plastic replacement loses.

Cheaper Than Replacement

Repairing sections, splicing timber and re-puttying costs far less than a set of new frames.

Warmer, Fewer Draughts

Repaired joints, new seals and draught-proofing cut heat loss and cold spots.

Windows That Last Decades

Properly restored timber windows can last another fifty years or more.

Right for Listed Buildings

Like-for-like repair keeps you compliant where replacement windows are not allowed.

Protects Property Value

Well-restored period windows help maintain and even lift what your home is worth.

Our Timber Window Repair & Restoration Process

From first visit to the final coat of paint, here is exactly what to expect.

Inspection & Quotation

We visit your property, check for hidden rot, damaged timber and movement in the joints, then send a detailed, itemised quote.

Timber Repair & Reglazing

Our craftsmen cut out decayed wood, splice in new treated timber, and rake out and replace failed putty using traditional methods.

Finishing & Quality Check

We sand, prime and repaint the restored frames, then check the weatherproofing and that every sash opens and closes smoothly.

Putty & Reglazing

Putty & Traditional Reglazing

Linseed oil putty is the traditional way to bed and seal glass into a timber window. Over decades it dries out, cracks and drops away, which lets water reach the timber and starts the rot cycle. Raking out the old putty and re-puttying is often all a sound single glazed window needs.

We hack out the failed putty, clean and prime the rebate, re-bed the glass, then strike a neat new fillet of linseed putty. It has to skin over for roughly two weeks before it can take paint, so we come back to prime and finish it properly. On a full restoration the reglazing is done as part of the same visit.

Re-puttying alone is usually enough when the frame is sound, the timber is dry and only the putty has perished. Full restoration is the right call when the timber is soft or spongy, the joints have moved, sashes stick or the cords have snapped.

Frequently Asked Questions

Do you repair rotten wooden window frames, or do they have to be replaced?

Most rotten frames can be saved. We cut out only the decayed timber and splice in new treated sections, or strengthen the joints with epoxy resin. Full replacement is a last resort.

Can you repair sash windows?

Yes. We replace broken sash cords, rebalance the weights, service the pulleys and add draught-proofing so box sash windows run smoothly and seal against draughts.

Can you re-putty just one or two windows?

Yes. If the timber is sound and only the putty has perished, raking it out and re-puttying with traditional linseed putty is often all that is needed.

How long before new putty can be painted?

Linseed putty needs to skin over before it takes paint, usually about two weeks depending on the weather. We return to prime and paint once it has cured.

Do you work on listed buildings and conservation areas?

Yes. Like-for-like repair with traditional materials is usually the right approach where replacement windows are restricted. We can provide a description of the works for your planning or listed building consent.

How long does timber window restoration take?

Small jobs such as re-puttying or a single splice are often done in a day. A full restoration of several windows takes longer and is confirmed at your on-site visit.

Which areas do you cover for timber and putty work?

We cover Uxbridge, Harefield, Rickmansworth, Mill End, Ruislip, Denham, Chalfont St Giles and the wider West London area.
