Window & door mastic in Benenden, Kent

About our window mastic in Benenden
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include rain getting in at the frame or under the sill and cold air getting in at the frame edge, across aluminium frames, patio & French doors and timber windows & doors.
Around Benenden, 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.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Do you need window mastic in Benenden?
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.
It’s worth asking for a quote if you see:
- Hard, cracked sealant around windows
- Gaps where the sill meets the wall
- A bead that does not match the frame
- Gaps left after new windows were fitted
For an older house near a landmark such as Church of St George, the joint between an old wall and a newer frame is normally the first place rain gets in.

- What happens if the job turns out different
- How long to leave it before use
Looking after it afterwards
To keep the joints looking good and working properly:
- Ventilate rooms so frames do not stay wet inside
- Keep solvents and bleach off the sealant
- Keep paint and stain on wooden frames in good order
- Keep drainage slots and sill grooves clear
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Quotes for window mastic in Benenden
We quote each job individually. This is what makes a difference:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- When we can work, for business premises
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
When you contact us, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or drop us an email.
How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. In a small place like Benenden, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Frames and glazing around Benenden
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Great Dixter (about 5 miles south) are a reminder that the area around Benenden has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Benenden Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in Benenden
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Older cottages and farmhouses around Benenden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
