Farnham Common Remedial Sealant
We cover Farnham Common for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Kitchen joints letting water behind the worktop
- Movement joints that have split or pulled away
- Products that weren’t meant for the joint
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
About our remedial sealant in Farnham Common
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. If you’re dealing with gaps opening along the back of the worktop and beads that never stuck properly, we can help, whatever the surface.
Around Farnham Common, it’s houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
There’s a 12-month guarantee on every job, whatever its size.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Clean sealant with mild products only
- Always have old sealant cut out, not covered
- Look for stains below bathrooms now and then
- Ask why a joint failed before redoing it
Where we have pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
- Sealant in an older building that needs testing for asbestos first
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
Surfaces we seal

What remedial sealant looks like in Farnham Common
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as St John the Evangelist, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Burnham station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Where is Mr Mastic based?
We work from Crawley. We cover Farnham Common and the rest of Slough, along with the rest of our area.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
What do you need from me for a quote?
Tell us what needs doing and where. We will ask anything else we need to know.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
My shower still leaks after a reseal. Can you sort it?
Yes, normally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a typical bath or shower, longer where several layers have been applied and we leave things clean and tidy. For a village or hamlet like Farnham Common, the journey is planned in advance: 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.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.

- We give you the cure time and explain what caused the failure.

Different surfaces, different methods
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. We rake that out where it can be removed and seal with a flexible product.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, which we’ll point out.
Do you need remedial sealant in Farnham Common?
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, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Signs it’s time to call us include:
- Repeat leaks from the same joint
- Floor or wall movement joints that have failed
- Worktop sealant that has shrunk and split
- Wide, uneven beads that look worse than the old ones
If you look after a building such as Farnham Common Junior School, we reseal washrooms and kitchens in schools and businesses as well as homes.
