Sash window repair in Barnet
Ask three firms about Sash Window Restoration in Barnet and you will get three different answers. Given the Victorian and Edwardian terraces, mansion blocks and post-war infill that dominates locally, standard sizes are the exception not the rule. Because of high pollution load and sheltered urban humidity, we see paint failure on south-facing sashes and rot at the bottom rail more often here than in most of the country. Everything we do here comes back to taking the window back to sound timber before anything is recoated.
Nothing is ordered until someone has stood in front of the opening with a tape. Ask us for a figure and you will get one, with the lead time stated alongside it.
A detail specific to this area: large numbers of properties sit in conservation areas with like-for-like replacement conditions.

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.
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.
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
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.
