About our sand mastic in Springhead
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. If you have modern sealant on a period surround and cracked mastic round a front door frame, we can put it right.
In a smaller place like Springhead, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Common questions in Springhead
Is sand mastic in a coastal place like Springhead any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Springhead within the area you cover?
Yes. Springhead is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Broken panes
- Crumbling stone or brickwork round the window
- Whether work needs listed building consent
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Signs you need sand mastic in Springhead
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they generally need raking out.
If you can see any of these, it’s time to have the joints looked at:
- Old sand mastic that has cracked, crumbled or fallen out
- Old cement repairs round a window that have failed
- Open joints round the window box
- Cracked mastic round a front door frame
For site and facilities teams at buildings such as Painters Ash Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Homes in smaller places like Springhead can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to a full day, depending on how many windows from start to finish. For a job in Springhead, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Sand mastic in Springhead: local notes
Springhead is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Cobham College (about 4.1 miles south-east) nearby, there’s older building stock in the area around Springhead as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Ebbsfleet International station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Parish Church of St Botolph, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
