Window mastic in Claygate Cross
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We are often asked to deal with water coming in at the bottom corners of a door and cracked sealant at the sill ends, on timber windows & doors, aluminium frames and patio & French doors.
Around Claygate Cross, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job.

What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames for a typical job. For a village or hamlet like Claygate Cross, the journey is planned in advance: 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.
- We check how each frame can be reached safely.
- 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.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Tell us about any water getting in

What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Faulty window hardware
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Composite doors
- uPVC windows
- Aluminium frames

Common questions in Claygate Cross
Is Claygate Cross within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Borough Green & Wrotham station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can you get sealant to suit coloured frames?
Generally, yes. Mention the frame colour when you ask for a quote and we will match it as closely as we can.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Window mastic in Claygate Cross: local notes
Historic houses like Old Soar Manor (about 0.9 miles south-east) are a reminder that the area around Claygate Cross has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Schools such as Borough Green Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to The Church of the Good Shepherd include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Borough Green & Wrotham station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Around Claygate Cross
Typical jobs here are in homes near Wrotham School, The Chequers Inn and Ivy Hatch Nature Reserve and the streets around them.

A little further out are Ightham Court (1.7 miles north-west) and Beechin Wood Archery Museum (1.1 miles north-east).
Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Older cottages and farmhouses around Claygate Cross can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Look round the frames every year or so
- Paint up to the joint, not over it
- Ventilate rooms so frames don’t stay wet inside
- Keep timber frames painted
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
