Double glazing and glazing repairs in Barnet.

Three Barnets, three different answers

Barnet is the second largest London borough by population and its housing is not uniform. What suits a Whetstone semi will be refused outright a few miles away.

WhereWhat is thereWhat normally suits it
Finchley, East Finchley, Friern BarnetVictorian and Edwardian terraces, bay fronted, many with original sashesSash replacement or sash repair, slim double glazing where the box allows
Whetstone, North Finchley, Mill Hill, EdgwareInterwar and 1930s semis, bay fronted, mostly replaced once alreadyFull double glazing, bay work, and flush sash where the elevation deserves it

A warning worth reading

Hampstead Garden Suburb is not a normal conservation area

The Suburb is covered by an Article 4 direction and administered with unusual rigour, and the Hampstead Garden Suburb Trust has its own approval process on top of the council's. In practice that means window changes which would be permitted development elsewhere need consent here, and materials are prescribed rather than suggested.

We are not going to sell you a uPVC window for a Suburb address. If you are inside it, the realistic options are like for like timber, or secondary glazing behind the existing window, which normally sidesteps the issue entirely because nothing on the elevation changes. We will tell you that at survey before you spend anything.

Questions

Glazing in Barnet, answered

Can I fit uPVC windows in Hampstead Garden Suburb?
Almost certainly not. The Suburb has an Article 4 direction and the Hampstead Garden Suburb Trust operates its own approvals on top of the council's, and materials are prescribed. Timber like for like, or secondary glazing behind the existing window, are the routes that actually work there.
Do you charge for travel to Barnet?
No. The whole borough is inside our standard coverage from Wood Green, for surveys, installation and emergency callouts.
What is the best option for a bay fronted 1930s semi in Whetstone?
Usually a full replacement in A-rated units, with the bay done in stages so the structure above stays supported. On a period elevation a flush sash casement is worth the small premium, because a stormproof one is visible as a replacement from the street.
Can original sash windows in Finchley be double glazed?
Often yes, using slim sealed units inside restored original boxes. It depends on the depth of the existing sash, which is why we survey before quoting. Where the box is too slim, secondary glazing gets you most of the benefit without touching the window.
Do you cover Mill Hill and Hendon?
Yes, along with Edgware, Golders Green, Totteridge, High Barnet and New Barnet. All standard coverage.
