DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
About our sand mastic in Ugley
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. Common call-outs are for cement or filler used on old window joints that has cracked and draughts and rain around sash boxes, on period & listed homes, tenement windows and timber door frames.
Homes in small places like Ugley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Your questions about sand mastic in Ugley
I let a flat near Elsenham station. Can you help?
Yes. We work for landlords and agents as well as householders. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover Ugley for sand mastic?
Yes, Ugley is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
How long will you be here?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Which is right for my windows, sand mastic or modern sealant?
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 will explain why.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
When will the new mastic be hard?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for property managers and facilities teams. We can quote a run of properties together.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Somewhere as small as Ugley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks

Windows and doors in Ugley
With historic houses such as Horham Hall (about 4.6 miles east) nearby, there’s older building stock in the area around Ugley as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in.

How to look after the new joints
Aftercare is simple:
- Keep modern sealant off the mastic
- Do not paint over the new mastic
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Timber that has rotted
- Putty and glazing repairs
- Sashes that need overhauling
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Timber door frames
- Period & listed homes
- Sash and case windows
- Brick reveals
- Tenement windows
- Stone surrounds
Common problems we fix in Ugley
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
Keep an eye out for any of the following:
- Wind and rain getting in round a sash window
- Modern sealant on a period surround
- Window mastic to renew ahead of painting
- Patchy fillers round a sash window
Rented homes near Elsenham station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
