What Affects the Cost of Sash Window Restoration?

Condition of the Windows

Windows in better condition will generally require less work.

Common issues that increase cost include:

• timber decay

• broken sash cords

• poor previous repairs

• significant draught issues

---

Number of Windows

Restoring multiple windows at the same time can often reduce the cost per window, as work can be carried out more efficiently.

---

Level of Restoration Required

Not all windows need full restoration.

Costs will vary depending on whether the work involves:

• basic servicing

• draught proofing

• timber repairs

• full restoration

Timber Repairs

Where timber has deteriorated, repairs can be carried out using specialist systems such as Repair Care.

The extent of the damage will influence the cost.

Draught Proofing

Adding draught proofing is a common upgrade and can significantly improve comfort. This is often included as part of restoration work.

Is Restoration Cheaper Than Replacement?

In most cases, yes.

Restoring existing sash windows is typically more cost-effective than full replacement, particularly when the original windows are structurally sound.

It also allows you to retain original features, which is especially important in period properties.

Long-Term Value

Sash window restoration should be viewed as a long-term investment.

Benefits include:
