Sand mastic in Jaywick
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for mastic round period door frames that has failed and mastic that needs renewing before redecorating, on stone surrounds, brick reveals and timber door frames.
In a smaller place like Jaywick, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Each job carries a 12-month guarantee, large or small.

What affects the quote in Jaywick
For a quick quote, just ask. The main things that affect it are:
- The product the joint needs
- Access and height
- Working hours on commercial sites
- Mould in or behind the old joints
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Roughly how big the job is
- What’s wrong with the joints now
- Photos by email, if that is easy
- Whether it’s a home or a business
We quote each job on its own. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
Can I do it myself?
If you do try it yourself, take your time over the 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.
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.
Surface by surface
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we’ll confirm what’s needed.
Common problems we fix in Jaywick
Timber frames move with the seasons. That movement opens up the mastic joint over time.
The most common problems we see are:
- Cracked mastic round a front door frame
- Tired mastic found when preparing windows for paint
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
For site and facilities teams at buildings such as Sir Martin Frobisher Academy, the mastic around its windows and doors needs looking after like any other building’s.

What happens on the day
The work is kept neat and contained to the joints we are treating, so you can carry on as normal.

For a job in Jaywick, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

Advice
Why deal with it now?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Homes in smaller places like Jaywick 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.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Windows and doors in Jaywick
Jaywick is within about 1 mile 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. 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 St Christopher, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Clacton-On-Sea station? Then any sash windows need sound mastic to keep draughts and rain out.

FAQs for Jaywick
I let a flat near Clacton-On-Sea station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Does living near the coast affect sand mastic in Jaywick?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
How long does the job take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll say how long yours will take.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic can sit properly.
What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
