Remedial sealant for homes and businesses in Bell Bar
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. We work on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant, and people most often call us about beads that never stuck properly and products that weren’t meant for the joint.
In a village or hamlet like Bell Bar, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Big or small, it’s backed by our 12-month guarantee in Bell Bar and across Hertfordshire.

What happens if it’s left?
Another bead over the top won’t fix a failed joint. It does not grip the old layer, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Bell Bar can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.

How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours, depending on how many layers have to come out. In a small place like Bell Bar, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit

What we are called out for in Bell Bar
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
Most people get in touch when they notice one of these:
- Black mould underneath the bead
- Sealant peeling off a dusty or damp surface
- Thick, messy sealant smeared over tiles
- Repeat leaks from the same joint
For an older house near a landmark such as United Reformed Church Brookmans Park, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- A cracked shower tray or bath (that needs repair or replacing)
- Water damage behind tiles that needs a tiler
- Sealant in an older building that needs testing for asbestos first
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use a soft cloth, not a scourer, on silicone
- Never seal over old silicone
- Keep movement joints clear of mortar and paint
- Find out why the sealant failed first
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
Do not keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
Common questions in Bell Bar
Do you work for landlords with property near Brookmans Park station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Will you come out to Bell Bar?
Yes. Bell Bar is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
How long will it take to strip and reseal the joint?
It takes a few hours for a typical bath or shower, longer where several layers have been applied. We will give you a timescale when we quote.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Is it worth trying it myself?
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.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Surface by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and tell you about any damage we find.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.
