Sand mastic in Deepcut

What we’re called out for in Deepcut

Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.

Common reasons people contact us include:

  • Old sand mastic that has cracked, crumbled or fallen out
  • Window mastic to renew ahead of painting
  • Patchy fillers round a sash window
  • Silicone on a period window that looks wrong

If you look after a building such as Sandringham Infant & Nursery School, the mastic around its windows and doors needs looking after like any other building’s.

What your quote should include

  • Whether all the old sealant comes out first
  • Which colour the sealant will be
  • How long to leave it before use
  • How long the guarantee is

How to choose a mastic man

About our sand mastic in Deepcut

Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on sash and case windows, period & listed homes and timber door frames, and people most often call us about failed mastic on an exposed elevation and mastic dropping out of the joint.

Houses in smaller places like Deepcut can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.

The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints from start to finish. In a smaller place like Deepcut, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Preparing for the visit

  • Clear the area around the work
  • Tell us if parking is tricky
  • Tell us about access, such as stairs, a lift or high-level joints

What we can’t put right

In fairness, there are a few things sealant will not fix:

  • Damaged stone surrounds
  • Decayed frames that need repair
  • Planning or listed building consent (your local planning authority decides)

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Where we work in Deepcut

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

Leave it or put it right?

Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. Around Deepcut, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
