Our sand mastic service in East Sussex

Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on timber door frames, period & listed homes and brick reveals, and people most often call us about modern sealant on a period surround and wind and rain getting in round a sash window.

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows.

We check the window surrounds and agree which joints need renewing.
The loose and crumbling mastic is raked out and the joint cleaned.
We pack any deep gaps so the mastic sits at the right depth.
The mastic is mixed, pressed into the joint by hand and shaped.
The finish is dressed so it sits neatly against the stone or brick.

Windows and doors across East Sussex

East Sussex has everything from older homes with timber frames to newer ones with uPVC. Walls facing the weather take the most punishment.

London and the South East have homes from every era, from period terraces to post-war new towns and new estates. The right sealant depends on the age and materials of the building. Parts of East Sussex are on or near the coast, where wind-driven rain and, closer to the shore, salt air are hard on outside sealant. Walls facing the sea are usually the first to need attention.

Eastbourne: If you look after a building such as Stafford Junior School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Hampden Park station, any sash windows need sound mastic to keep draughts and rain out.

Why it fails

Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.

The most common problems we see are:

Silicone on a period window that looks wrong
Draughts and rain around sash boxes
Gaps round a timber door in stone or brick
Crumbling sand mastic round a window

What happens if it’s left?

Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes.

How we quote for sand mastic

Every job gets its own quote. This is what makes a difference:

Any mould that needs treating
The number and length of the joints
When we can work, for business premises
How much old sealant there is and how hard it is to remove

The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

The address or postcode of the job
A few pictures by email, if you can
What’s wrong with the joints now
Whether it’s a home or a business

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

DIY sealant or a professional job?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Landlord and commercial work in East Sussex

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

East Sussex questions

Can new sealant go over the old?

No. We remove every bit of old sealant first.

Can old silicone round a sash window be swapped for sand mastic?

In most cases. We remove the silicone and clean the joint, then point it with sand mastic.

Is consent needed for window work on a listed home?

It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.

What guarantee comes with the work?

You get our one-year guarantee on every job.

Are you insured?

Yes. We are fully insured.

Where are you based?

We are based in Crawley, and we work across South East England, London and Scotland.

Is it possible to paint over sand mastic?

Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
