Sand mastic for homes and businesses in Marley
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on tenement windows, sash and case windows and timber door frames, and the jobs we see most are crumbling sand mastic round a window and gaps where the frame meets the masonry.
Somewhere as small as Marley, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

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. Where a wall is exposed, as many are in small places like Marley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, 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 sand mastic looks like in Marley
Marley is close to 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 older windows and doors, especially on the side facing the sea. Historic houses like Walmer Castle (about 3.5 miles south-east) are a reminder that the area around Marley has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Augustine, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Sandwich station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
Marley is about 3 miles north-west of Deal, in Kent. Across the CT14 area, our applicators can take on sand mastic. Marley is one of 922 places in Kent we cover for sand mastic. We also work in Chelmsford, around 51 miles away.
We cover every part of CT14 for sand mastic. If you need sand mastic at a property on Broad Lane and Marley Lane or anywhere close by, we can help. Neighbouring places we cover for sand mastic include Finglesham (1 mile north-east), Hacklinge (1 mile north-east), Northbourne (1 mile south), Ham (1 mile north-west) and Sholden Meadows (1 mile south-east). We also work in nearby towns such as Canterbury (12 miles west), Margate (10 miles north), Dover (7 miles south), Folkestone (13 miles south-west), Ramsgate (8 miles north-east) and Broadstairs (10 miles north-east).
Local landmarks in Marley

What we’re called out for in Marley
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Look out for these signs:
- Gaps between timber frames and stone or brick
- Patchy fillers round a sash window
- Crumbling sand mastic round a window
- Draughty sash windows at the surround
If you look after a building such as Northbourne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Questions from Marley
Do you cover smaller places like Marley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Sandwich station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
What does sand mastic cost?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us with a short description of the job.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Sashes that rattle, stick or won’t open
- Planning or listed building consent (your local planning authority decides)
- Decayed frames that need repair
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

The process
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. After that, the work takes anything from a few hours to a full day, depending on how many windows. Somewhere like Marley needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
