Sand mastic for homes and businesses in Godstone
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We work on sash and case windows, brick reveals and tenement windows, and people most often call us about patchy fillers round a sash window and open joints round the window box.
Outdoor sealant needs dry, clean surfaces, so work on frames around Godstone is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, you get the same 12-month guarantee.

Why it’s worth doing now in Godstone
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Older cottages and farmhouses around Godstone can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Godstone, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Windows and doors in Godstone
Historic houses like Titsey Place (about 4.1 miles north-east) are a reminder that the area around Godstone has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Godstone station, older sash windows in a rental need their mastic kept sound to keep the weather out.

When to call us in Godstone
Timber frames move with the seasons. The movement cracks the mastic over time.
Any of these means the joints need attention:
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
- Gaps between timber frames and stone or brick
- Failed mastic on an exposed elevation
Schools such as Godstone Village School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- Whether VAT is included
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Take care around the mastic when scraping paint
- Find out about consent before window work on a listed home
- Don’t paint over the new mastic
- Make sure water runs off the sill
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
