What we do, step by step
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. It normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Chartridge, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- 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.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Clear items away from the joints we are working on

How we handle remedial sealant in Chartridge
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. We are often asked to deal with a second bead peeling off the first and worktop sealant that has shrunk and split, on botched or over-sealed joints, expansion joints and leaking tray & enclosure joints.
Around Chartridge, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
Our work is backed for twelve months, in Chartridge and everywhere else we cover.

Chartridge: your questions answered
I let a flat near Great Missenden station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover smaller places like Chartridge?
Yes. Chartridge is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Different surfaces, different methods
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint is not the cause, we’ll say so.
Common problems we fix in Chartridge
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
The problems people usually mention when they call are:
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
- Floor or wall movement joints that have failed
- Repeat leaks from the same joint
If you look after a building such as Chartridge Combined School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Why act early in Chartridge
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out, and the joint treated and dried before resealing. Around Chartridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Bathrooms and kitchens in Chartridge
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 landlords with property near Great Missenden station, a joint that keeps failing is best fixed properly while the property is empty. Homes close to St John's Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Get the cause of a repeat leak found before resealing
- Don’t add new sealant on top of old
- Keep movement joints clear of mortar and paint
- Keep bleach and abrasives off the bead
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just call 0345 464 0079 or send us an email.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
