- Damp patches on the reveal after heavy rain
Window mastic in Chiltington, done properly
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We are often asked to deal with cracked sealant at the sill ends and sealant in the wrong colour for the frame, across timber windows & doors, aluminium frames and window sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Chiltington is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, it’s backed by our one-year guarantee in Chiltington and across East Sussex.

What we need to know

- Any previous sealing or DIY work
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved

What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Chiltington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
Why book with us
- You choose the colour before work begins
- Experience in homes, commercial sites and hotels

What we can’t put right
We will always be straight with you, so here’s what new sealant will not do:
- A door that needs adjusting, rehanging or new seals
- Damp coming through the wall itself rather than the frame joint
- Rotten timber, which needs a joiner first
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

Signs you need window mastic in Chiltington
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
These are the problems we’re asked about most:
- Untidy mastic left by window fitters
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
- Mastic that’s falling out in pieces
Homes close to The Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes most of a day for a typical house, less for a few frames. In a small place like Chiltington, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

Chiltington homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Anne of Cleves House (about 3.7 miles south) nearby, there’s older building stock in the area around Chiltington 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 is traditional sand mastic.
Schools such as Chailey School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Cooksbridge station, renewing tired window mastic between tenants heads off draught and damp complaints.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
- Keep jet washers away from the mastic
Silicone cannot usually be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
