Window mastic in Angmering-on-Sea, done properly
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you’re dealing with leaking joints at the ends of sills and a bead that doesn’t match the frame, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Angmering-on-Sea is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months.

Angmering-on-Sea: your questions answered
Do you work for landlords with property near Angmering station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Is window mastic in a coastal place like Angmering-on-Sea any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long will my window job take?
The work takes a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Do you work in Angmering-on-Sea?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Angmering-on-Sea.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Windows and doors in Angmering-on-Sea
Angmering-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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
Letting a property close to Angmering station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around The Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we are called out for in Angmering-on-Sea
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
If you can see any of these, it’s time to have the joints looked at:
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
- White mastic on grey or black frames
- Untidy mastic left by window fitters
For site and facilities teams at buildings such as East Preston Infant School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Which colour the sealant will be
- Which sealant they’ll use, and why
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Worn gaskets, brush seals or a door that has dropped
- Condensation trapped between the panes
- Faulty window hardware
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.

What happens if it’s left?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Angmering-on-Sea can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we will talk you through it.
