About our remedial sealant in Essendon
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. We work on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints, and the jobs we see most are dark patches showing through the sealant and products that weren’t meant for the joint.
Somewhere as small as Essendon, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Never fill a movement joint with mortar or grout
- Ask why a joint failed before redoing it
- Do not add new sealant on top of old
- Look for stains below bathrooms now and then
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Leave it or put it right?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Where a wall is exposed, as many are in small places like Essendon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Common questions in Essendon
Do you cover Essendon for remedial sealant?
Yes, Essendon is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Can you help a landlord with a rental near Bayford station?

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you remove sealant that is been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
How long will it take to strip and reseal the joint?
The number of joints and layers decides it. You will have a timescale before any work begins.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.

What we do, step by step
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied, and we explain the cure time before we leave. Somewhere as small as Essendon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Move anything stored near the joints
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
How to get a quote

What else we do in Essendon
Different surfaces, different methods
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint isn’t the cause, we’ll say so.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. We strip it back so we can see the joint, then reseal neatly.
Bathrooms and kitchens in Essendon
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For an older house near a landmark such as Church of St Mary the Virgin, walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Essendon CofE (VC) Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

When to call us in Essendon
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, can’t stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
Keep an eye out for these signs:
- Dark patches showing through the sealant
- Repeat leaks from the same joint
- Beads that never stuck properly
- Worktop sealant that has shrunk and split
Rented homes near Bayford station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.
