Window & door mastic in Maynard's Green, East Sussex
Professional window mastic in and around Maynard's Green, with every bit of old sealant taken out first and a 12-month guarantee.
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
Why act early in Maynard's Green
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Maynard's Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Maynard's Green
- A sealant colour to suit the surroundings
- White, clear, grey or coloured to suit, where the product allows
- Homes, businesses and hotels
- Old sealant always removed completely

How we handle window mastic in Maynard's Green
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. If you have black, perished sealant on frames and gaps where the sill meets the wall, we can help, whatever the surface.
In a village or hamlet like Maynard's Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
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.

Windows and doors in Maynard's Green
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 Horselunges Manor (about 4.2 miles south) nearby, there’s older building stock in the area around Maynard's Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
When it is not the sealant
It helps to know what we cannot do too:
- Faulty window hardware
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
What we seal
- Aluminium frames
- Timber windows & doors
- uPVC windows
- Patio & French doors
- Window sills
- Composite doors
How we quote for window mastic
Your quote is based on your job. We look at:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- The number and length of the joints
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and send you a clear quote before any work starts.
Helping us quote
To make quoting easier, please include:
- Where the property is
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
Do you need window mastic in Maynard's Green?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Most people get in touch after spotting something like this:
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
- White mastic on grey or black frames
- Gaps where the sill meets the wall
If you look after a building such as Maynards Green Community Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- How long to leave it before use
- What product goes in the joint
- Whether they seal over old material or remove it
- Whether you can choose the colour
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Maynard's Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Let us know about earlier repairs to the joints
