What else we do in Hawkenbury
Sand mastic in Hawkenbury: local notes
Historic houses like Groombridge Place (about 3.9 miles west) are a reminder that the area around Hawkenbury has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Tunbridge Wells station, any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as St Peter's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why it’s worth doing now in Hawkenbury
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. In a smaller place like Hawkenbury, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.

The process
There is not much for you to do on the day. 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. A visit to Hawkenbury is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
How to get a quote
Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand, and we’ll take it from there.

Common problems we fix in Hawkenbury
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
People normally contact us when they notice one of these:
- Mastic worn away on windows facing the weather
- Gaps between timber frames and stone or brick
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
If you look after a building such as Claremont Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- What happens if the job turns out different
- Which colour the sealant will be
- Is VAT in the price?
- How long the guarantee is
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Planning or listed building consent (your local planning authority decides)
- Sashes that rattle, stick or will not open
- Timber that has rotted
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
