Window mastic in Allhallows-on-Sea, done properly
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on composite doors, aluminium frames and uPVC windows, and people most often call us about mastic that’s falling out in pieces and gaps between the frame and the inside reveal.
Mastic can only go onto a dry, clean joint, so window work in Allhallows-on-Sea is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Why deal with it now?
Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Allhallows-on-Sea can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.

What we’re called out for in Allhallows-on-Sea
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
These are the problems we are asked about most:
- Draughts coming in around windows and doors
- Damp patches on the reveal after heavy rain
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
If you live in an older home near Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.

Surface by surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.

What else we do in Allhallows-on-Sea
Windows and doors in Allhallows-on-Sea
Allhallows-on-Sea is close to 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Allhallows Primary Academy, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Chalkwell station, renewing tired window mastic between tenants heads off draught and damp complaints.

Common questions in Allhallows-on-Sea
Can you help a landlord with a rental near Chalkwell station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Does living near the coast affect window mastic in Allhallows-on-Sea?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
DIY sealant or a professional job?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
