Window Mastic in Tidebrook
Problem with your window and door frames in Tidebrook? We remove the old material, prepare the joints and seal them properly.
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
About our window mastic in Tidebrook
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include cold air getting in at the frame edge and leaking joints at the ends of sills, across timber windows & doors, composite doors and uPVC windows.
Homes in small places like Tidebrook 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.
All our work is covered by our one-year guarantee.

When to call us in Tidebrook
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Signs it’s time to call us include:
- Mastic that’s falling out in pieces
- Cracked or shrunken mastic around the frame
- A bead that does not match the frame
- Damp patches on the reveal after heavy rain
If you live in an older home near The Parish Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Before you book anyone
- Is the old sealant removed completely?
- Are they insured?
- How the surfaces are prepared before sealing
- How long to leave it before use
Why it’s worth doing now in Tidebrook
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In a small place like Tidebrook, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach 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: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Tidebrook homes and the weather
With historic houses such as Wadhurst Castle (about 2.3 miles north-east) nearby, there’s older building stock in the area around Tidebrook 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Uplands Community College are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Wadhurst station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Is Tidebrook in your area for window mastic?
Yes, Tidebrook is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Tidebrook?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
How long will my window job take?

Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Can I paint over the new sealant?
Not normally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
uPVC windows
uPVC expands and contracts noticeably with temperature, 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.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep jet washers away from the mastic
- Look round the frames every year or so
- Do not use solvent cleaners on the joint
- Keep drainage slots and sill grooves clear
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
How the visit works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames for a typical job. For a village or hamlet like Tidebrook, 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.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
