What we do and how we do it
Sash Window Replication in the UK rewards patience at the setting-out stage. You will find mostly a mix of period and modern stock in this area, and it moves as it ages. the full range of UK exposure conditions is the local complication, and coating failure followed by rot at the joints is what it eventually causes. What you are paying for is copying the surviving original rather than approximating it.
The survey happens before manufacture, which is why our units fit without packing or trimming. Get in touch and we will be straight with you about cost and timescale.
Something particular to this area: specification should always be matched to local exposure.
Specification
- Engineered hardwood or slow-grown softwood, FSC certified
- Factory-applied microporous finish in any RAL or heritage colour
- Sealed units, slim-cavity units or single glazing with putty line
- Manufactured to survey dimensions, not to a stock size chart
- Delivered UK-wide with chain-of-custody paperwork
Replication, not approximation
Profiles copied from the surviving original, section by section.
Drawings for consent
Measured section drawings supplied to accompany a listed building application.
Conservation glazing
Slim-cavity units and genuine putty lines where the consent requires them.
Fabric retained where possible
We splice and repair before we replace, because the original is the point.
What clients tell us
Feedback collected directly from completed projects. Full written references are available on request before you commit.
“The conservation officer approved the sections first time, which had not happened with the previous applicant.”
Verified client, UK-wide“They spliced the original cill rather than replacing it, which was exactly what we wanted.”
Verified client, UK-wide“The putty lines look right, and from the street you cannot tell which windows are new.”

Frequently asked questions
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
