Sand mastic in Whitewood

Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. If you have mastic round period door frames that has failed and silicone on a period window that looks wrong, we can help, on sash and case windows, period & listed homes and tenement windows alike.

Homes in small places like Whitewood often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

Whatever the size of the job, it’s backed by our 12-month guarantee.

What the job involves on each surface

Stone surrounds

Stone surrounds suit sand mastic well. The finish blends with the masonry.

Timber door frames

Round a period front door, sand mastic gives the right look.

Why act early in Whitewood

Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Older cottages and farmhouses around Whitewood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Why us?

  • Anti-fungal sanitary silicone in wet areas
  • We’re fully insured
  • An ARBOMaster approved applicator
  • A 12-month guarantee on all work

I let a flat near Godstone station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Do you offer different sealant colours?

We help you choose a colour that suits. The product needed can limit the range.

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

What do you need from me for a quote?

Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.

What’s sand mastic made of?

Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.

Is it possible to paint over sand mastic?

Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll advise.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Go gently near the mastic when preparing windows
  • Check with your local planning authority if your home is listed
  • Leave the new mastic unpainted
  • Keep modern sealant off the mastic

Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.

Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

When to call us in Whitewood

Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps round a timber door in stone or brick
  • Gaps where the frame meets the masonry
  • Patchy fillers round a sash window
  • Window mastic to renew ahead of painting

If you live in an older home near Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What your quote should include

  • What insurance they hold
  • What happens if the job turns out different
  • How the colour is chosen
  • What guarantee comes with the work

How to choose a mastic man

How it works

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a single window, longer for several in most cases. For a village or hamlet like Whitewood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Tell us about any water getting in
  • Mention any parking rules near the property

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
