About our remedial sealant in Falconwood
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. We work on failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints, and the jobs we see most are over-sealed joints coming away and gaps opening along the back of the worktop.
Hard London water leaves limescale on sealant, grout and taps alike. In Falconwood, remedial sealant is as much about a room looking cared for as about keeping water out.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Bathrooms and kitchens in Falconwood
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
For site and facilities teams at buildings such as Bishop Ridley Church of England VA Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. As a London address, Falconwood can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Your questions about remedial sealant in Falconwood
Do you work for landlords with property near Welling station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can parking be tricky for a visit in Falconwood?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can I choose the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How long does remedial resealing take?
It takes a few hours for most joints, depending on how much old sealant has to come out. We will give you a timescale when we quote.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
What we are called out for in Falconwood
Joint depth matters. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing sets the depth and stops that.
Common reasons people contact us are:
- Over-sealed joints coming away
- A shower that leaks however often it’s resealed
- Sealant peeling off a dusty or damp surface
- Gaps opening along the back of the worktop
Homes close to Bishop Ridley Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Landlords, agents and businesses in Falconwood
Housing providers, facilities teams and property managers book us too in Falconwood and across Greater London. Several sites can go on one quote, and we are fully insured.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Falconwood, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Quality sealants from Arbo and Everbuild
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting
- We agree the colour with you first

How the job changes by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning before resealing.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In a London area like Falconwood, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- 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.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
