How we handle remedial sealant in Farnham Royal
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. We work on botched or over-sealed joints, mouldy bath & shower sealant and expansion joints, and common reasons people get in touch are thick, messy sealant smeared over tiles and decorators’ caulk around a bath or shower.
Being in a small place like Farnham Royal 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.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Your questions about remedial sealant in Farnham Royal
I let a flat near Burnham station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Do you work in hotels near Farnham Royal?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
How long does remedial resealing take?
That depends on how many layers there are and how many joints. You will have a timescale before any work begins.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Should I try DIY first?
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.
Do you need remedial sealant in Farnham Royal?
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. Then the only fix is removal and a new bead.
Most people get in touch after spotting one of these:
- Floor or wall movement joints that have failed
- Decorators’ caulk around a bath or shower
- Mould trapped under a layer of silicone
- Beads that never stuck properly
Letting a property close to Burnham station? Then a joint that keeps failing is best fixed properly while the property is empty.
Questions to ask before booking
- How hidden problems are handled
- How much experience the applicator has
- Whether they seal over old material or remove it
- What insurance they hold
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
How the job changes by surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and tell you about any damage we find.
What affects the quote in Farnham Royal

Helping us quote
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
We don’t publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, phone 0345 464 0079 or email us.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act on a lifting corner right away
- Always have old sealant cut out, not covered
- Run the fan after every shower
- Keep movement joints clear of mortar and paint
Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Farnham Royal, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Mention if the joints have been sealed before

Farnham Royal has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as St Mary's Farnham Royal CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
