The process
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. For a village or hamlet like Hurstbourne Tarrant, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- 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.
Getting ready for the visit

Advice
How we handle sand mastic in Hurstbourne Tarrant
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on stone surrounds, period & listed homes and timber door frames, and the jobs we see most are a silicone bead on a sash window that spoils the look and window mastic to renew ahead of painting.
In a village or hamlet like Hurstbourne Tarrant, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard.

FAQs for Hurstbourne Tarrant
Do you cover Hurstbourne Tarrant for sand mastic?
Yes, Hurstbourne Tarrant is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
I let a flat near Andover station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
How long does sand mastic take to go off?
It takes a while. It skins first and hardens fully later and we will give you an idea for your job.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Should I use sand mastic or silicone?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Sand mastic in Hurstbourne Tarrant: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Hurstbourne Tarrant Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in.

How the job changes by surface
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
Stone surrounds
The stone is treated with care while raking out the old mastic.
When to call us in Hurstbourne Tarrant
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
If you let a flat or house near Andover station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Why act early in Hurstbourne Tarrant
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Around Hurstbourne Tarrant, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
- Avoid patching sand mastic with silicone
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
