About our sand mastic in Hampton
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We are often asked to deal with modern sealant on a period surround and mastic dropping out of the joint, on period & listed homes, brick reveals and tenement windows.
In a smaller place like Hampton, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
Every job is covered by a 12-month guarantee, wherever you are in Kent.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Hampton: your questions answered
Do you cover smaller places like Hampton?
Yes. Hampton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is sand mastic in a coastal place like Hampton any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
How much does sand mastic cost in Hampton?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
What affects the cost of sand mastic
You’ll get a clear quote before any work starts. It’s based on:
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
You do not need to know the technical terms. Just tell us:
- If someone has resealed it before
- What’s wrong with the joints now
- Where the property is
- Pictures of the joints, sent by email

Sand mastic in Hampton: local notes
Hampton is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Herne Bay station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around St Andrew's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Hampton is about 2 miles west of Herne Bay, in Kent. We provide sand mastic to homes and businesses in Hampton and nearby. Hampton is one of 922 towns and villages in Kent where we work. Our Chelmsford page covers work nearby.

People usually contact us when they notice one of these:
- Modern sealant on a period surround
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Mastic dropping out of the joint

What we seal
- Brick reveals
- Period & listed homes
- Timber door frames
- Stone surrounds
- Tenement windows
- Sash and case windows
How the job changes by surface
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Timber door frames
Round a period front door, sand mastic gives the right look.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. Parking around Hampton is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
