Remedial sealant in Farnham, done properly
Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. We work on botched or over-sealed joints, expansion joints and shrunken worktop sealant, and the jobs we see most are products that weren’t meant for the joint and dark patches showing through the sealant.
Most bathrooms in a town like Farnham are in family homes, used every day, which is hard on sealant and grout. The usual signs are mould in the bead, gaps by the sink and grout that is cracked or stained.
There’s a 12-month guarantee on every job.

How it works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. In Farnham, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- 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.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Let us know about earlier repairs to the joints

What else we do in Farnham
What we’re called out for in Farnham
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Signs it’s time to call us include:
- A second bead peeling off the first
- Torn expansion joints
- Worktop sealant that has shrunk and split
- Products that weren’t meant for the joint
Letting a property close to Farnham station? Then a joint that keeps failing is best fixed properly while the property is empty.

What remedial sealant looks like in Farnham
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. There are hotels and other places to stay in and around Farnham. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
In the older streets around St Joan of Arc's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Schools such as Farnham College are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What sealant work can’t fix

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
How the job changes by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.
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.
FAQs for Farnham
Do you work in hotels near Farnham?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can you do remedial sealant in Farnham?
Yes, Farnham is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone will not bond to silicone.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is remedial work guaranteed?
Yes. Our one-year guarantee covers the work, and we are ARBOMaster approved.
Do you have insurance?
Yes. We’re fully insured.
How to look after the new joints
So the new joints stay in good condition:
- Check ceilings under showers for marks
- Have loose fittings fixed before resealing
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
If we have 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.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
