Window mastic in Burwash Common
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. Common call-outs are for leaking joints at the ends of sills and untidy mastic left by window fitters, on composite doors, timber windows & doors and window sills.
Somewhere as small as Burwash Common, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Landlords and letting agents in Burwash Common can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
How to look after the new joints
After the cure time, these simple habits help:
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
- Make sure the drainage slots aren’t blocked
- Don’t use solvent cleaners on the joint
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Penetrating damp from a failed cavity tray or render
- Faulty window hardware
- Draughts through the window seals rather than the frame

Burwash Common: your questions answered
Is Burwash Common within the area you cover?
Yes, Burwash Common is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Stonegate station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
How long will my window job take?
Allow anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is the new sealant paintable?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do you guarantee window mastic?
Yes. Our 12-month guarantee covers every job.
How the visit works
At the end, we look at the finished work together. The visit itself normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job.

Advice
Common problems we fix in Burwash Common
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Look out for any of the following:
- Mastic that is falling out in pieces
- Draughts coming in around windows and doors
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
If you live in an older home near St Philip's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Window mastic in Burwash Common: local notes
With historic houses such as Bateman's (about 1.8 miles east) nearby, there’s older building stock in the area around Burwash Common as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
For landlords with property near Stonegate station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
