If you’re dealing with floor or wall movement joints that have failed and worktop sealant that has shrunk and split, we can help, whatever the surface.
Being in a small place like Somerton makes no difference to the job itself: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.

Questions from Somerton
I let a flat near Heyford station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Somerton?
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.
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.
Is remedial work guaranteed?
Yes. Our one-year guarantee covers the work, and we’re ARBOMaster approved.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
What if the leak isn’t the sealant?
You’ll hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, and we won’t reseal for the sake of it.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Why it’s worth doing now in Somerton
Another bead over the top won’t fix a failed joint. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. Where a wall is exposed, as many are in small places like Somerton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep the room well ventilated
- Report a tray that rocks or a worktop that lifts
- Clean sealant with mild products only
- Keep movement joints clear of mortar and paint
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
Surface by surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Worktops & kitchens
Kitchen joints hold grease and residue, so cleaning takes longer than in a bathroom before resealing.
How we quote for remedial sealant
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- How many areas need sealing
- Access and height
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
Helping us quote
To make quoting easier, let us know:
- The rough size of the job
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs

What we do, step by step
At the end, we look at the finished work together. The visit itself normally takes a few hours, depending on how many layers have to come out, depending on how much there is to do. Somewhere like Somerton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
DIY versus a professional finish
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Bathrooms and kitchens in Somerton
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Homes close to Church of St James include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Heyford station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
