FAQs for Leysdown-on-Sea
Does living near the coast affect window mastic in Leysdown-on-Sea?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Leysdown-on-Sea in your area for window mastic?
Yes, Leysdown-on-Sea is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long does it take to reseal the windows on a house?
Allow a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
About our window mastic in Leysdown-on-Sea
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, ring 0345 464 0079 or drop us an email with the number of frames and any access details. We work on composite doors, timber windows & doors and aluminium frames, and the jobs we see most are draughty joints inside around the window and cracked sealant at the sill ends.
In a village or hamlet like Leysdown-on-Sea, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our 12-month guarantee.

When it is not the sealant
It helps to know what we cannot do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
- A sash or casement that will not close properly
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

- Patio & French doors
- Composite doors
- uPVC windows
- Aluminium frames
- Window sills
- Timber windows & doors
Surface by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep paint off silicone joints
- Ventilate rooms so frames do not stay wet inside
- Use gentle cleaners on frames and sealant
- 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.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Leysdown-on-Sea homes and the weather
Leysdown-on-Sea is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Whether the job is in Leysdown-on-Sea itself or nearby, the right material for each joint matters as much as a neat finish. Around Leysdown-on-Sea, as everywhere, window mastic is only as good as the preparation behind it.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why deal with it now?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Leysdown-on-Sea, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Leysdown-on-Sea, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
