About our window mastic in Filching
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have gaps left after new windows were fitted and gaps where the sill meets the wall, we can put it right, on aluminium frames, composite doors and timber windows & doors alike.
Somewhere as small as Filching, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
All our work comes with our one-year guarantee.

Filching questions
Do you work for landlords with property near Polegate station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you do window mastic in Filching?
Yes. We work across London and the South East, and Filching is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you seal inside as well as outside?
Yes. Inside, the joint between frame and plaster is sealed neatly.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How many windows can you do in a day?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
Quotes for window mastic in Filching
The quote reflects the job in front of us. We look at:
- The number of rooms or windows
- Any working-time requirements on site
- The product the joint needs
- How much old sealant there is and how hard it is to remove
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
When you call or email, it’s useful to know:
- How we’d reach the joints
- How many joints, rooms or windows are involved
- If someone has resealed it before
- The type of property
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or send us an email.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Damp problems in the wall away from the window
- Faulty window hardware
- Soft or decayed wood in the frame
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere like Filching needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Windows and doors in Filching
Historic houses like Alfriston Clergy House (about 2.9 miles west) are a reminder that the area around Filching has older buildings as well as new. 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.
If you live in an older home near The Parish Church of Saint Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Willingdon Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Common problems we fix in Filching
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
The most common problems we see are:
- Draughty joints inside around the window
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
- A bead that doesn’t match the frame
Rented homes near Polegate station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
