How we handle window mastic in Tendring Green
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you have mastic that has split away from the wall and leaking joints at the ends of sills, we can help, whatever the surface.
Homes in small places like Tendring Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

Do you need window mastic in Tendring Green?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints at the ends of sills
- White mastic on grey or black frames
- Gaps left after new windows were fitted
- Whistling draughts around closed windows
For site and facilities teams at buildings such as Tendring Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Tendring Green questions
Do you work for landlords with property near Weeley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Tendring Green within the area you cover?
Yes, Tendring Green is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Is the work guaranteed?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning for a couple of windows and a door, and the area is left clean. In a small place like Tendring Green, 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.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Getting ready for the visit
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Mention any parking rules near the property

Related advice
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Window mastic in Tendring Green: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Thorpe Hall (about 3.6 miles south-east) are a reminder that the area around Tendring Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Weeley station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Church of St Edmund, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Looking after it afterwards
After the cure time, these simple habits help:
- Paint up to the joint, not over it
- Don’t aim a pressure washer at the joints
- Do not use solvent cleaners on the joint
- Keep drainage slots and sill grooves clear
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What affects the quote in Tendring Green
You will get a clear quote before any work starts. It’s based on:
- Access and height
- The product the joint needs
- Mould in or behind the old joints
- The amount of work
Doing several joints on one visit is usually more efficient than separate visits. We’ll give you a clear price for the lot.
