Window mastic in Chillenden, 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 work on aluminium frames, window sills and patio & French doors, and people most often call us about a bead that doesn’t match the frame and mastic that has split away from the wall.
Homes in small places like Chillenden often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints
So the new joints stay in good condition:
- Do not paint over the silicone
- Make sure the drainage slots aren’t blocked
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Honest limits
Before you book, it’s worth knowing the limits too:
- Penetrating damp from a failed cavity tray or render
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal

- Window sills

Windows and doors in Chillenden
Historic houses like Goodnestone Park (about 1.2 miles north-west) are a reminder that the area around Chillenden has older buildings as well as new. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Goodnestone Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Aylesham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Different surfaces, different methods
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In a small place like Chillenden, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Mention any sign-in or site rules at work premises
