Guide prices

The prices shown on this page are intended as a general guide only.
Original sash windows vary greatly in size, condition, construction and accessibility, so the final cost may be higher or lower.

A guide price is not a quotation or an offer to carry out the work at a fixed price. Wherever possible, I will explain what is required and agree the price before work begins.

Additional work will not be carried out without discussing it with you first.

1. Sash Cord Replacement

What does sash cord replacement cost?

Straightforward sash cord replacement starts from £60.00 per cord.

The final price depends on whether one or both sashes require new cords,
the size and weight of the sashes, paint build-up, access to the sash pockets
and the condition of the pulleys and weights.

The guide price assumes that the window can be opened and dismantled normally.
Stuck sashes, damaged pulleys, missing weights, previous alterations or rotten timber may involve additional work.

I will explain any additional work before carrying it out.

2. Sticking Sash Window Repair

What does it cost to free a sticking sash window?

Straightforward easing and adjustment starts from £40.00 per sash

The price depends on why the sash is sticking.
Common causes include paint build-up, swollen timber, damaged sash cords, poor alignment, distorted timber and previous repairs
and if the sashes have been previously screwed or nailed shut

The guide price covers normal easing and adjustment.
It does not include extensive paint removal, replacement cords, timber repairs, glazing work or replacement fittings unless these are specifically agreed.

I will assess the likely cause and explain the options before carrying out additional work.

3. Sash Pulley Replacement

What does sash pulley replacement cost?

Straightforward pulley replacement starts from £___ per pulley or £___ per window, depending on the work required.

The final price depends on the type of pulley, whether a suitable replacement is available, the condition of the pulley housing and how easily the sash can be dismantled.

Where possible, I repair or adapt the existing pulley housing rather than unnecessarily replacing sound original timber.

Rotten timber, damaged housings, seized fixings or unusual pulley sizes may involve additional work. 

This will be discussed before the repair proceeds.

4. Sash Window Draught Proofing

What does sash window draught proofing cost?

Draught proofing starts from £___ per window.

The final price depends on the size and design of the window, the number of opening sashes and the condition of the existing timberwork.

The guide price assumes that the sashes and frame are basically sound and can be removed and refitted normally.

Broken cords, seized pulleys, rotten timber, damaged glass, extensive paint removal or major adjustment are not included unless specifically agreed.

I will explain what is included before the work begins.

5. Sash Window Overhaul

What does a sash window overhaul cost?

A straightforward sash window overhaul starts from £___ per window.

An overhaul may include removing the sashes, checking the cords and pulleys, easing the moving parts, making normal adjustments and putting the window back into working order.

The exact work required varies from window to window.

The guide price does not automatically include replacement glass, extensive paint removal, draught proofing, major timber repairs, replacement pulleys or structural repairs to the box frame.

Any additional work will be explained and agreed separately.

6. Rotten Sash Window Repair

What does it cost to repair rotten timber in a sash?

Small, localised timber repairs start from £___.

The final price depends on the amount of decay, its position, whether the sash must be removed, the condition of the surrounding timber and whether glazing must be disturbed.

Rot is often more extensive beneath the paint than it first appears. For that reason, photographs may allow me to provide an initial guide, but the full extent may not be known until unsound timber has been opened up.

If further decay is discovered, I will explain the position before carrying out work beyond what has already been agreed.

7. Rotten Cill Replacement or Repair

What does a rotten window cill repair cost?

Localised cill repairs start from £___.

A larger repair or replacement section will cost more, depending on the length and depth of the decay, access, the condition of the box frame and whether adjoining timber has also been affected.

The guide price assumes that the damage is limited to the visible area. Hidden decay may only become apparent once loose paint and rotten timber have been removed.

Where practical, I repair only the defective timber and retain as much of the original window as possible.

Any significant additional work will be discussed before proceeding.

8. Box Frame Repair

What does a sash-window box frame repair cost?

Small localised box-frame repairs start from £___.

The final cost depends on the position and extent of the damage, access to the affected area and whether internal linings, architraves or decorations must be disturbed.

Damage to a box frame can sometimes extend farther than is visible from the surface. A firm price may therefore require closer inspection or careful opening of the damaged area.

The guide price does not include redecoration, plaster repairs or making good by other trades unless specifically stated.

I will explain what is included before work begins.

9. Box Sash Repair

What does a box sash window repair cost?

Minor repairs to a box sash window start from £___.

Because “box sash repair” can cover anything from a broken cord to significant frame decay, the final price depends on the exact fault and the condition of the window.

After seeing photographs or inspecting the window, I will explain whether the work is likely to involve cords, pulleys, easing, timber repairs, draught proofing or a more complete overhaul.

Each element of the work will be clearly described so that you understand what is included.

10. Glazing and Glass Replacement

What does sash-window glass replacement cost?

Replacing a straightforward pane of glass starts from £___, depending on the size and type of glass.

The final cost depends on access, the condition of the glazing bars, the type and thickness of the glass and whether old putty can be removed without damaging the surrounding timber.

Specialist, patterned, toughened, laminated or heritage glass will cost more than standard glass.

Any timber repairs discovered during removal of the glass will be discussed separately.

11. General Timber Splicing Repairs

What do timber splicing repairs cost?

Small timber splicing repairs start from £___.

Each repair is individually shaped to remove unsound material while retaining as much original timber as practical.

The final price depends on the size, shape and location of the repair, access, the condition of the surrounding timber and the amount of dismantling required.

The guide price does not include full redecoration unless specifically stated.
