Problem with your window and door surrounds in Stoneyhills? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.

About our sand mastic in Stoneyhills
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you have tired mastic found when preparing windows for paint and draughty sash windows at the surround, we can put it right.
Somewhere as small as Stoneyhills, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, large or small.

What the job involves on each surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- Broken panes
- Whether work needs listed building consent
- Decayed frames that need repair

What we do, step by step
We keep the work tidy and contained to the joints we are treating. The job generally takes a few hours for a single window, longer for several, and we tell you how long to leave it before we go. Somewhere like Stoneyhills needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- 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 mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children

Your questions about sand mastic in Stoneyhills
Do you cover smaller places like Stoneyhills?
Yes, Stoneyhills is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Burnham-On-Crouch station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
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’ll advise.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you match the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Landlord and commercial work in Stoneyhills
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
What happens if it’s left?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Where a wall is exposed, as many are in small places like Stoneyhills, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why us?

What affects the cost of sand mastic
We quote each job individually. These are the things that affect it:
- Any mould that needs treating
- The product the joint needs
- Whether the work is at height
- Whether old sealant or filler has to be cut out
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Any previous sealing or DIY work

Windows and doors in Stoneyhills
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Burnham-On-Crouch station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Ormiston Rivers Academy, the mastic around its windows and doors needs looking after like any other building’s. Homes close to St Mary's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
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.
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 fails, we can still redo it.
