Sand mastic in Turville Heath, done properly

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. If you have silicone on a period window that looks wrong and mastic worn away on windows facing the weather, we can put it right, whatever the surface.

Outdoor sealant needs dry, clean surfaces, so work on frames around Turville Heath is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

Turville Heath homes and the weather

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Stonor Park (about 1 mile south) nearby, there’s older building stock in the area around Turville Heath as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Why it’s worth doing now in Turville Heath

Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Turville Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Decisions on consent for listed homes
  • Damaged stone surrounds
  • Timber that has rotted

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Joints and surfaces we work on

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

The process

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours per window, depending on the condition of the joints from start to finish. Somewhere as small as Turville Heath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

How to prepare

  • On commercial sites, let us know about site rules
  • Mention any leaks or damp you’ve noticed
  • Where the joints are inside, avoid wetting them before we arrive

Can I choose the sealant colour?

Most of the time, yes. We’ll tell you which colours the right product comes in.

How to look after the new joints

So the new joints stay in good condition:

  • Make sure water runs off the sill
  • Ask us before painting near the mastic
  • Get any rot dealt with first
  • Keep modern sealant off the mastic

Look at the mastic when you look over the windows. Small cracks are easier to deal with early.

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

When to call us in Turville Heath

Timber frames move with the seasons. That movement opens up the mastic joint over time.

Signs it’s time to call us include:

  • Draughty sash windows at the surround
  • A silicone bead on a sash window that spoils the look
  • Weathered mastic on the most exposed windows
  • Patchy fillers round a sash window

Around Turville Heath, as everywhere, sand mastic is only as good as the preparation behind it.

What your quote should include

  • How long the guarantee is
  • What happens if the job turns out different
  • What the cure time is
  • Whether the sealant suits the joint

How to choose a mastic man

Can I do it myself?

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.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
