Sash Window Repairs & Restoration Peterborough

Traditional Sash Window Specialists in Peterborough

If you own a period property in Peterborough—whether Victorian, Edwardian, or Georgian—you already know that sash windows are a defining feature of your home’s character. But original timber sash windows require specialist care. That’s where NJS Sash Window comes in.

Based locally and established in 2005, NJS Sash Window is a trusted name for sash window repairs, restoration, and draught proofing across Peterborough and the surrounding Cambridgeshire area . Led by founder Nick Smith, the business is built on traditional joinery skills and a deep respect for period properties, including Grade II and Grade II listed buildings* .

Our Sash Window Services in Peterborough

We offer a full range of sash window services tailored to period properties across Peterborough.

Sash Window Repairs

Don’t replace what can be repaired. Many original sash windows can be brought back to life with expert repairs. We fix:

Broken sash cords and pulleys
Sticking or jammed sashes
Cracked or single-glazed panes
Worn or missing parting beads and staff beads

We carefully remove your window, carry out repairs off-site where needed, and reinstall with minimal disruption.

Sash Window Draught Proofing

Draughty sash windows are a common complaint in older Peterborough homes. Our discreet brush pile and rubber seal draught proofing systems dramatically reduce air leakage—without changing the look of your windows. Benefits include:

Lower heating bills
Reduced noise from outside
No more rattling sashes

Timber Window Repairs & Resin Bonding

Rotten timber doesn’t always mean a full replacement. We use advanced resin repair techniques to rebuild decayed sections of wooden frames and cills. This preserves original fabric—often a requirement for listed buildings and conservation areas—while providing a durable, weatherproof finish.

Sash Window Replacement

When a window is beyond repair, we craft like-for-like timber sash windows using sustainably sourced hardwoods and softwoods . Our replacements match your original profiles, mouldings, and glazing patterns—so no one would ever know they’re new.

Sash Cord & Weight Replacement

Snapped cords are one of the most common sash window faults. We replace cords, rebalance weights, and ensure your windows open and close smoothly again.

Sash Windows & Listed Buildings in Peterborough

Peterborough has numerous conservation areas—including Queens Road, the city centre, and many village conservation zones—as well as hundreds of listed buildings. If your home is in one of these areas, replacing sash windows with uPVC or non-matching designs often requires planning permission and may be refused .

NJS Sash Window specialises in like-for-like timber replacements and sympathetic repairs that satisfy conservation officers. We work with you—and where necessary, your local planning authority—to ensure your windows remain compliant while performing beautifully.

“From a heritage consideration, the replacement windows will be in keeping with the character of the original dwelling and will retain the character and appearance of the conservation area.” – Peterborough City Council Delegated Report

We apply the same careful approach to every period property we touch.

Traditional vs Modern Sash Windows: What’s Right for Your Home?

Timber Sash Windows

Original timber sash windows were typically made from slow-grown softwoods or English oak. Modern timber windows use sustainable softwoods like Scots pine, European redwood, or Accoya(a high-durability treated timber) .

Pros:

Visually authentic – perfect for listed buildings
Can be repaired multiple times over decades
Breathable – better for old buildings

Cons:

Requires regular painting/maintenance
Higher upfront cost for quality timber

uPVC Sash Windows

uPVC sash windows mimic the look of timber but require far less maintenance .

Pros:

Low maintenance – no painting
Good thermal efficiency (with double glazing)
Lower initial cost

Cons:

Often refused in conservation areas
Can warp or discolour over time
Difficult or impossible to repair

For most period properties in Peterborough’s conservation zones, timber remains the only acceptable option. NJS Sash Window provides both, but we always advise honestly based on your property and budget.

Frequently Asked Questions

How much do sash window repairs cost in Peterborough?

Can you draught proof original sash windows without changing how they look?

Yes. Our draught proofing systems are fitted into the existing frame and are virtually invisible when closed. Your windows will look exactly the same, but without the draught.

Do you work on listed buildings?

Yes. We have extensive experience working on Grade II and Grade II listed properties* across Cambridgeshire and beyond . We understand what conservation officers look for and will advise accordingly.

How long does a sash window repair take?

Minor repairs (cords, beads, minor timber repairs) are often completed within 1–2 days. Full restorations may take up to a week, depending on the number of windows and workshop time required for off-site repairs.

Do you replace single glazing with double glazing?

Yes. We can fit slim-profile double glazing into existing sash window frames, subject to planning consent. This improves thermal efficiency while retaining the original timber frame.

What’s the difference between a box sash and a Yorkshire sash?

A box sash slides vertically (up and down) and is the most common type found in Peterborough. A Yorkshire sash slides horizontally (side to side) and is less common but found in some properties . We repair both.

Are you local to Peterborough?

Absolutely. We’re based in Etton (PE6 7DA) and have been serving Peterborough homeowners since 2005 .
