Sand mastic for homes and businesses in Wivenhoe Cross
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on brick reveals, tenement windows and stone surrounds, and people most often call us about mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look.
In a smaller place like Wivenhoe Cross, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Do you need sand mastic in Wivenhoe Cross?
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Most people get in touch when they notice one of these:
- Old cement repairs round a window that have failed
- Mastic worn away on windows facing the weather
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes
Letting a property close to Wivenhoe station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Frames and glazing around Wivenhoe Cross
Wivenhoe Cross is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
In the older streets around The Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Broomgrove Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. In a smaller place like Wivenhoe Cross, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit

Common questions in Wivenhoe Cross
Does living near the coast affect sand mastic in Wivenhoe Cross?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you work for landlords with property near Wivenhoe station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
Can I choose the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
How much does sand mastic cost in Wivenhoe Cross?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Why act early in Wivenhoe Cross
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a smaller place like Wivenhoe Cross, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before we start.
