What sand mastic looks like in Well Head
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Goodnestone Park (about 1.6 miles south) are a reminder that the area around Well Head has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Wingham Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about sand mastic in Well Head
Is Well Head in your area for sand mastic?
Yes, Well Head is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
I let a flat near Adisham station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before we start.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Check with your local planning authority if your home is listed
- Avoid patching sand mastic with silicone
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
What we do, step by step
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work normally takes anything from a few hours to a full day, depending on how many windows. In a small place like Well Head, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Advice
Do you need sand mastic in Well Head?
Rain on the window surround works into any crack and loosens it further. Exposed elevations generally fail first.
Any of these means the joints need attention:
- Crumbling sand mastic round a window
- Mastic worn away on windows facing the weather
- Gaps between timber frames and stone or brick
- Cement or filler used on old window joints that has cracked
If you let a flat or house near Adisham station, older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- What insurance they hold
- Whether they seal over old material or remove it
- Is VAT in the price?
- What happens if they find a problem under the old sealant
Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Well Head, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What else we do in Well Head
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
