Sand mastic for homes and businesses in Elsted
We work across Elsted renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have gaps between timber frames and stone or brick and silicone on a period window that looks wrong, we can put it right, on stone surrounds, period & listed homes and tenement windows alike.
In a village or hamlet like Elsted, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Elsted, 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.
- First we agree which joints need doing.
- 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.

Advice
Frames and glazing around Elsted
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Uppark (about 2.7 miles south-west) are a reminder that the area around Elsted 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.
If you live in an older home near The Parish Church of St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why deal with it now?
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Elsted can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Looking after it afterwards
So the new joints stay in good condition:
- Go gently near the mastic when preparing windows
- Renew mastic before redecorating the windows
- Make sure water runs off the sill
- Leave the new mastic unpainted
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

Can I add another job to the visit?

Which is right for my windows, sand mastic or modern sealant?
We’ll help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.

Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
