This is where we write about sash windows in London homes, because most problems have simple causes. Our guides cover repair versus replacement, draught proofing, double glazing and the costs involved. Our specialists write each one in plain English.
What you will find here
Most guides start with a problem you can see or hear. For example, a window might rattle, stick or let in a cold draught. We explain the likely cause, what a repair involves and when replacement makes sense.
We favour refurbishing the joinery already in your home over ripping it out. Our specialists can usually repair original timber, and the result keeps the look of the building. However, we are honest when a window is beyond saving, and our guides say so too.
Cost questions come up in almost every conversation. For that reason, several guides give real prices, and they match our price list. You can also read about sash window repair costs in London before you ask for a quote.
Each guide is short and focused, so you can read it in a few minutes. Most end with a clear next step, whether that is a repair, a price check or a free visit. Because every home differs, treat the guides as a starting point rather than a firm quote.
