- Planning or listed building consent (your local planning authority decides)
- Timber that has rotted
- Damaged stone surrounds

Sand mastic in Shottenden, done properly
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. Typical jobs include a silicone bead on a sash window that spoils the look and draughts and rain around sash boxes, on sash and case windows, stone surrounds and tenement windows.
Somewhere as small as Shottenden, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee.

What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work usually takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Shottenden, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Tell us about any water getting in

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Sort the mastic before the decorators arrive
- Get any rot dealt with first
- Make sure water runs off the sill
- Check the mastic when you check the paintwork
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Windows and doors in Shottenden
With historic houses such as Belmont House and Gardens (about 3.7 miles north-west) nearby, there’s older building stock in the area around Shottenden as well as newer homes. 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Shottenden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Shottenden: your questions answered

Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is Shottenden in your area for sand mastic?
Yes. We work across London and the South East, and Shottenden is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
