Sand mastic in Hatton
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you’re dealing with window mastic to renew ahead of painting and cement or filler used on old window joints that has cracked, we can help, whatever the surface.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
Our work is backed for twelve months.

Questions from Hatton
Is parking an issue for sand mastic in Hatton?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Is Hatton in your area for sand mastic?
Yes. Our work covers London and the South East, and Hatton is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
How long does sand mastic take to go off?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What sealant work can’t fix
We won’t take on work that won’t last, so these are the limits:
- Decayed frames that need repair
- Damaged stone surrounds
- Sashes that need overhauling
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Joints and surfaces we work on
- Brick reveals
- Period & listed homes
- Timber door frames
- Stone surrounds
- Tenement windows
- Sash and case windows
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. In a London area like Hatton, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Signs you need sand mastic in Hatton
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
The problems people generally mention when they call include:
- Modern sealant on a period surround
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
If you let a flat or house near Heathrow Terminal 4 Rail station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
What your quote should include
- Is VAT in the price?
- Whether all the old sealant comes out first
- How the colour is chosen
- What guarantee comes with the work
Frames and glazing around Hatton
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
Managing a site like Cranford Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Hatton is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Near you in Hatton

What happens if it’s left?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
