Why act early in West Burton

Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Where a wall is exposed, as many are in small places like West Burton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

How we handle sand mastic in West Burton

Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We are often asked to deal with crumbling sand mastic round a window and draughts and rain around sash boxes, on brick reveals, period & listed homes and tenement windows.

Somewhere as small as West Burton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Every job comes with a 12-month guarantee.

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. In a small place like West Burton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Where the joints are inside, avoid wetting them before we arrive
  • Keep children and pets away from the work area

Frames and glazing around West Burton

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Bignor Roman Villa (about 0.8 miles north-west) are a reminder that the area around West Burton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Rented homes near Amberley station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Bury CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near The Parish Church of the Holy Cross, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

  • What’s wrong with the joints now

  • Whether it’s a home or a business

Different surfaces, different methods

Sash and case windows

A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.

Period and listed homes

A traditional finish suits a period property, and sand mastic is one of them.

What sealant work can’t fix

To be straight with you, some problems need a different trade:

  • Whether work needs listed building consent
  • Broken panes
  • Masonry that needs repairing

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Joints and surfaces we work on

  • Brick reveals
  • Period & listed homes
  • Timber door frames
  • Stone surrounds
  • Tenement windows
  • Sash and case windows

How to look after the new joints

Looking after new joints is easy:

  • Take care around the mastic when scraping paint
  • Sort the mastic before the decorators arrive
  • Clear gutters so water does not pour onto the windows
  • Don’t run silicone over sand mastic

When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.

Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
