Warmer old houses.Same old windows.

We draught-proof sash windows, doors, floors and lofts in Victorian and Edwardian houses. Nothing ripped out, nothing plastic.

An old house is not cold because it is old. It is cold because of a hundred small gaps. We find them, seal them, and leave the windows your house was built with.

Most of our work is in streets like this one, built between 1870 and 1914.

Everything an old houseloses its heat through

All our work
  • An old white sash window with many panes looking out onto green trees.

    Sash windows

    Overhauled, re-corded and sealed

  • A dark blue front door with a fanlight in a red-brick house, autumn leaves in front.

    Front doors

    Brushes, seals and a new letterbox

  • The inside of a loft with silver insulation between the wooden rafters.

    Lofts

    Topped up with sheep's wool

  • A tall old window in a dark room with a tree outside.

    Shutters

    Rehung, so they close at night

A third of the cost of new windows

Overhauling and sealing a sash costs about £450. A new double-glazed one in the same style costs three times that, and the old glass is gone for good.

Step 02

We plan it by room

A fixed price per window and door, the worst gaps first, so you can do it all at once or a room a year.

Step 03

We do the work

One window out at a time, boarded while it is in the workshop. Back in the same day, painted the next.

The job

Before you call usfour things to check

  1. Hold a lit candle by each window on a windy day. Where the flame leans, there is a gap.
  2. Look under the front door. If you see daylight, so does the wind.
  3. Push the bottom sash up gently. If it rattles, the beads are loose.
  4. Check the loft hatch. It is often the biggest hole in the house.

Questionseveryone asks

Will my windows look different?
No. The seals sit inside the frame. From the street nothing changes except that the windows open properly.
Do you work in conservation areas?
Yes. Repair and draught-proofing do not usually need permission, and we will tell you if yours does.
How long does one window take?
About a day each, including paint. A whole house is usually one to two weeks.
Is it worth it if I plan to move?
Working, sealed sash windows are something buyers of old houses look for. Most people get the cost back.
Do you do secondary glazing?
Only where sealing is not enough, in slim timber frames that lift out in summer.

Not sure where to start?

Every job starts with one conversation and one survey. £90, taken off the bill.
