Remedial sealant for homes and businesses in Roehampton
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. Common call-outs are for torn expansion joints and black mould underneath the bead, on expansion joints, shrunken worktop sealant and failed movement joints.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Roehampton more than a cosmetic job.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Do not wait for a small gap to become a leak
- Always have old sealant cut out, not covered
- Keep an eye on the ceiling below the bathroom
- Get the cause of a repeat leak found before resealing
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Roehampton and across Greater London. We can quote a run of properties together, and we are fully insured.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Why act early in Roehampton
Mould under a bead cannot be reached by cleaning. The layers have to come out. In a flat in Roehampton, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

Surface by surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.
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.
The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Roehampton. It helps if you can point us to a visitor permit or a bay close to the door.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Remedial sealant around Roehampton

Roehampton is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Granard Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Your questions about remedial sealant in Roehampton
Can parking be tricky for a visit in Roehampton?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you work for landlords with property near Barnes station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
What if the leak is not the sealant?
We check for that before we reseal. If the fault is elsewhere, you’ll know before any work is done.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Someone sealed over the old bead. Can you fix it?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
When something else is needed
A few problems are outside what sealant work can do:
- A cracked shower tray or bath (that needs repair or replacing)
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A tray or worktop that needs refixing first
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Shrunken worktop sealant
- Mouldy bath & shower sealant

Signs you need remedial sealant in Roehampton
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
Most people get in touch when they notice something like this:
- Gaps opening along the back of the worktop
- Caulk or the wrong sealant used in a wet area
- Leaks that keep coming back after resealing
- A second bead peeling off the first
For landlords with property near Barnes station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- Which colour the sealant will be
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- What preparation is included
