Sand mastic in Chingford Hatch
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. If you’re dealing with window mastic to renew ahead of painting and open joints round the window box, we can help.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Chingford Hatch is something to talk through when you book.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Why it’s worth doing now in Chingford Hatch
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. 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.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why book with us
- Old sealant always removed completely
- Every job guaranteed for a year
- ARBOMaster approved applicator

Chingford Hatch homes and the weather
Historic houses like Bruce Castle (about 3.7 miles west) are a reminder that the area around Chingford Hatch 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. 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.
Schools such as Longshaw Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Highams Park station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Questions from Chingford Hatch
Do you cover Chingford Hatch for sand mastic?
Yes. Our work covers London and the South East, and Chingford Hatch is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Highams Park station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
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.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
How long will you be here?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll tell you how long to expect.
