Window mastic in Chillerton, done properly
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on uPVC windows, timber windows & doors and composite doors, and people most often call us about old mastic that has gone black or come away and hard, cracked sealant around windows.
Homes in small places like Chillerton 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.
You get a one-year guarantee, the same in Chillerton as everywhere else we work.

Chillerton homes and the weather
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. With historic houses such as Sheat Manor (about 0.6 miles north-east) nearby, there’s older building stock in the area around Chillerton 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’s traditional sand mastic.
If you live in an older home near St. Olave's Church, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Chillerton and Rookley Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in Chillerton
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Chillerton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Different surfaces, different methods
Composite doors
Front doors take the weather head on. Those corners get the most care.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Honest limits
Before booking, it’s worth knowing the limits:
- Penetrating damp from a failed cavity tray or render
- A door that needs adjusting, rehanging or new seals
- Condensation trapped between the panes
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

How we quote for window mastic
Jobs vary more than people expect. The main factors:
- Any mould that needs treating
- When we can work, for business premises
- How many rooms, windows or areas are involved
- Which sealant suits the joint
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What we need to know
To help us quote quickly, please include:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- If someone has resealed it before
- What’s wrong with the joints now
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or drop us an email.

How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere like Chillerton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
