What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- When we can work, for business premises
- The old material and how stubborn it is
- The size of the job
- Whether there’s mould to deal with
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
To make quoting easier, let us know:
- The problem you’ve noticed

- Roughly how big the job is
- Whether it has been sealed before

Remedial sealant for homes and businesses in Barkham
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. If you are dealing with thick, messy sealant smeared over tiles and a second bead peeling off the first, we can help.
Somewhere as small as Barkham, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Barkham homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as Church of St James, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Wokingham station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why it’s worth doing now in Barkham
Another bead over the top won’t fix a failed joint. It does not grip the old layer, so the leak carries on and there’s now more to remove. In a small place like Barkham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Anti-fungal silicone where joints get wet

What else we do in Barkham
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Barkham, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Keep children and pets away from the work area

What the job involves on each surface
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
When to call us in Barkham
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing sets the depth and stops that.
Most people get in touch after spotting one of these:
- Thick, messy sealant smeared over tiles
- Decorators’ caulk around a bath or shower
- A shower that leaks however often it’s resealed
- Gaps opening along the back of the worktop
Schools such as The Coombes Church of England Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Your questions about remedial sealant in Barkham
Can you help a landlord with a rental near Wokingham station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Barkham?
Yes, Barkham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.
My shower still leaks after a reseal. Can you sort it?
Yes, generally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
