About our remedial sealant in Westwick Row
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. Common call-outs are for wide, uneven beads that look worse than the old ones and caulk or the wrong sealant used in a wet area, on shrunken worktop sealant, mouldy bath & shower sealant and leaking tray & enclosure joints.
Somewhere as small as Westwick Row, 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Westwick Row needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
Getting ready for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area

What else we do in Westwick Row
Looking after it afterwards
After the cure time, these simple habits help:
- Do not add new sealant on top of old
- Get the cause of a repeat leak found before resealing
- Deal with small splits early
- Check trays and worktops don’t move
Where we’ve pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Different surfaces, different methods
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We will tell you what we find.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is generally part of the cause. We’ll reseal and tell you if extraction looks to be the issue.
What we’re called out for in Westwick Row
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Any of these means the joints need attention:
- Dark patches showing through the sealant
- Sealant applied over old sealant that has lifted
- Kitchen joints letting water behind the worktop
- Beads that never stuck properly
Managing a site like Leverstock Green Church of England Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Your questions about remedial sealant in Westwick Row
Do older homes in Westwick Row need their sealant replacing?
Normally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant will not stick to old, so the old bead has to come out completely first.
Can you help a landlord with a rental near Apsley station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
How much does remedial sealant cost in Westwick Row?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Can you reseal a split movement joint?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
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.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What information do you need?
A short description and the location, with photos by email if possible. If we need more, we’ll ask.
Remedial sealant around Westwick Row
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings. Hemel Hempstead, which Westwick Row is part of, is one of England’s post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. New sealant won’t stick to old, so the old layers have to come out first.
For landlords with property near Apsley station, botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as Church of Holy Trinity, walls and floors in older homes can move, and sealant and grout show it first.

How we quote for remedial sealant
The price is agreed before any work begins. It takes into account:
- Whether old sealant or filler has to be cut out
- Access and height
- The amount of work
- The product the joint needs
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 play a part, and we will explain the quote if you ask.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- A few pictures by email, if you can
- Where the property is
- Whether it’s a home or a business
- The problem you’ve noticed
For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
What happens if it’s left?
Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. In a small place like Westwick Row, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
