Sand mastic for homes and businesses in Rock-a-Nore
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on stone surrounds, timber door frames and brick reveals, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and silicone on a period window that looks wrong.
Many houses in smaller places like Rock-a-Nore have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Sand mastic in Rock-a-Nore: local notes
Rock-a-Nore is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Ebenezer Particular Baptist Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Ark Castledown Primary Academy, larger buildings have plenty of frames, and the mastic around each one ages.

FAQs for Rock-a-Nore
Does the coastal weather in Rock-a-Nore affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Rock-a-Nore?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Where do you work from?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Homes in smaller places like Rock-a-Nore 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.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why choose Mr Mastic in Rock-a-Nore

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Whether work needs listed building consent
- Broken panes
- Sashes that need overhauling
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

How the visit works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours per window, depending on the condition of the joints. For a job in Rock-a-Nore, 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 look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
