Sand mastic in Beckley, done properly
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. Typical jobs include cracked mastic round a front door frame and silicone on a period window that looks wrong, across period & listed homes, sash and case windows and timber door frames.
Mastic can only go onto a dry, clean joint, so window work in Beckley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee.

What affects the cost of sand mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Whether there’s mould to deal with
- How easy the joints are to reach
- The size of the job
- Working hours on commercial sites
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Where the property is
- If someone has resealed it before

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Can you do sand mastic in Beckley?
Yes, Beckley is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.

Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
How long does sand mastic take?
That depends on how much there is to do, but as a guide it takes a few hours for a single window, longer for several. We will give you a better idea when we quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

Beckley homes and the weather
With historic houses such as Great Dixter (about 2.3 miles west) nearby, there’s older building stock in the area around Beckley as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to The Parish Church of All Saints include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Beckley Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Leave the new mastic unpainted
- Get any rot dealt with first
- Check with your local planning authority if your home is listed
- Plan mastic work ahead of painting
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
When to call us in Beckley
Water gets into small cracks in the mastic and loosens it further. Exposed elevations generally fail first.
The problems people usually mention when they call are:
- Crumbling sand mastic round a window
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
- Draughty sash windows at the surround
If you let a flat or house near Winchelsea station, older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- Are they insured?
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
- When the joint can take water or movement
