FAQs for Sutton at Hone
Is Sutton at Hone in your area for sand mastic?
Yes. We work across London and the South East, and Sutton at Hone is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Farningham Road station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later, and we will tell you what to expect.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
How do I get a quote for sand mastic in Sutton at Hone?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
Sutton at Hone homes and the weather
Historic houses like Lullingstone Castle (about 3.9 miles south-west) are a reminder that the area around Sutton at Hone 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 is traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Farningham Road station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Sutton-At-Hone Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
- Don’t run silicone over sand mastic
- Check with your local planning authority if your home is listed
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Whether work needs listed building consent
- Sash cords, weights and draught-proofing of the sashes
- Putty and glazing repairs
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. For a village or hamlet like Sutton at Hone, 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 look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
How to get a quote

Quotes for sand mastic in Sutton at Hone

- How many rooms, windows or areas are involved
