How we handle window mastic in Norton
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before we start. To get one, phone 0345 464 0079 or send us an email with the number of frames and any access details. We work on aluminium frames, window sills and patio & French doors, and the jobs we see most are rain getting in at the frame or under the sill and whistling draughts around closed windows.
Around Norton, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Frames and glazing around Norton
Norton is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Alfriston Clergy House (about 3.2 miles east) nearby, there’s older building stock in the area around Norton as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as UTC@Harbourside, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Andrew include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Norton
The work is quick compared with the damage it prevents: it takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Norton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Norton questions
Do you cover smaller places like Norton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Does living near the coast affect window mastic in Norton?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
How do I get a quote for window mastic in Norton?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Signs you need window mastic in Norton
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Any of these means the joints need attention:
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
- Draughty joints inside around the window
- Hard, cracked sealant around windows
For landlords with property near Bishopstone (Sussex) station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- What product goes in the joint
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- How hidden problems are handled
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
