Sand mastic for homes and businesses in Little Chart Forstal
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you have mastic that needs renewing before redecorating and mastic worn away on windows facing the weather, we can put it right, whatever the surface.
In a village or hamlet like Little Chart Forstal, 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.
You get a one-year guarantee, the same in Little Chart Forstal as everywhere else we work.

Questions from Little Chart Forstal
Will you come out to Little Chart Forstal?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Charing station?
Yes. We work for landlords and agents as well as householders. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Little Chart Forstal.
What information do you need?
Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
Frames and glazing around Little Chart Forstal
With historic houses such as Godinton House (about 2.2 miles south-east) nearby, there’s older building stock in the area around Little Chart Forstal 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Charing station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Do you need sand mastic in Little Chart Forstal?
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
These are the problems we’re asked about most:
- Tired mastic found when preparing windows for paint
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
- Modern sealant on a period surround
In the older streets around St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- The length of the guarantee
- How the surfaces are prepared before sealing
- How much experience the applicator has
- Whether they seal over old material or remove it
What we cannot put right
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Putty and glazing repairs
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that need overhauling
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Period & listed homes
- Tenement windows
- Timber door frames
- Sash and case windows
- Brick reveals
- Stone surrounds
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
What affects the quote in Little Chart Forstal
Some jobs are bigger than they look, and some smaller. The main factors:
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- The product the joint needs
- Whether there’s mould to deal with
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- If someone has resealed it before
- The rough size of the job
- The problem you’ve noticed
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or send us an email.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask a joiner to look at soft timber first
- Don’t run silicone over sand mastic
- Avoid heavy scraping on the mastic joint
- Sort the mastic before the decorators arrive
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
