Sash window repair in Merton
Sash Cord Replacement is one of those jobs in Merton where the survey decides everything. You will find mostly Victorian and Edwardian terraces, mansion blocks and post-war infill in this area, and it moves as it ages. high pollution load and sheltered urban humidity sets the pace of decay, and paint failure on south-facing sashes and rot at the bottom rail is how it shows up first. The part that matters is rebalancing weights so the sash holds at any height.
Nothing goes into manufacture until a surveyor has checked each opening on site. Rough dimensions and a couple of photographs are enough for us to price it properly.
One local point to factor in: large numbers of properties sit in conservation areas with like-for-like replacement conditions.

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.
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.
Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
Is the timber certified?
All our stock is FSC certified and chain-of-custody documentation is supplied with the order, which most main contractors and specifiers now require for their records.
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.
