How we handle sand mastic in Pease Pottage
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Typical jobs include failed mastic on an exposed elevation and tired mastic found when preparing windows for paint, across period & listed homes, tenement windows and brick reveals.
Homes around Pease Pottage range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.

When to call us in Pease Pottage
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint and we normally remove them.
Any of these means the joints need attention:
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
- Silicone on a period window that looks wrong
Schools such as Discovery New School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Pease Pottage
How the job changes by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows. For a job in Pease Pottage, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit

- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Related advice
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Pease Pottage, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Pease Pottage: your questions answered
Can you help a landlord with a rental near Crawley station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is it worth replacing old sealant in an older home in Pease Pottage?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. The key is cutting all the old sealant out, as new sealant will not bond to it.
Are you insured?
Yes. Mr Mastic is fully insured.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you guarantee sand mastic work?
Our 12-month guarantee applies on every job.
