How it works
At the end, we look at the finished work together. The visit itself usually takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job. Parking around East Saltdean is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
Window mastic for homes and businesses in East Saltdean
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have gaps between the frame and the inside reveal and rain getting in at the frame or under the sill, we can put it right, whatever the surface.
In smaller places like East Saltdean, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.

How we quote for window mastic
Jobs vary more than people expect. The main factors:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- The size of the job
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

There’s no need for technical detail. It helps if you can tell us:

East Saltdean questions
Is window mastic in a coastal place like East Saltdean any different?
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.
Do you cover smaller places like East Saltdean?
Yes. East Saltdean is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you do upstairs windows?
Yes, in most cases. Access is planned before any work starts, so mention the height and anything in the way.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What window mastic looks like in East Saltdean
East Saltdean 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Monk's House (about 3.2 miles north-east) are a reminder that the area around East Saltdean has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Southease station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

When to call us in East Saltdean
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
Look out for these signs:
- Gaps where the sill meets the wall
- Cracked or shrunken mastic around the frame
- White mastic on grey or black frames
- Old mastic that has gone black or come away
For site and facilities teams at buildings such as Saltdean Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around East Saltdean, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots are not blocked
- Keep timber frames painted
- Don’t paint over the silicone
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Broken hinges, locks or handles
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
