How we handle remedial sealant in Comp
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. Typical jobs include torn expansion joints and leaks that keep coming back after resealing, on expansion joints, leaking tray & enclosure joints and failed movement joints.
For a small place like Comp, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Why deal with it now?
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. Around Comp, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Comp: your questions answered
Can you do remedial sealant in Comp?
Yes, Comp is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Borough Green & Wrotham station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
What if the leak isn’t the sealant?
You’ll hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we won’t pretend it will.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.

Common problems we fix in Comp
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Look out for any of the following:
- Mould trapped under a layer of silicone
- Beads that never stuck properly
- Torn expansion joints
- Gaps opening along the back of the worktop
Managing a site like Platt Church of England Voluntary Aided Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Quotes for remedial sealant in Comp
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- The amount of work

Helping us quote
When you contact us, these details help:
- Any previous sealing or DIY work
- Roughly how big the job is
- Access, such as stairs, a lift or height
- The address or postcode of the job
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work and send you a clear quote.
How to look after the new joints
After the cure time, these simple habits help:
- Don’t wait for a small gap to become a leak
- Have loose fittings fixed before resealing
- Do not point over movement joints
- Air the bathroom so the sealant can dry
If the joint ever needs renewing, have it cut out, not sealed over. New silicone does not bond to old, so the old bead should always come out first.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
How the job changes by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is generally part of the cause. We will reseal and tell you if extraction looks to be the issue.
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before we reseal.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on how many layers have to come out. In a small place like Comp, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

Bathrooms and kitchens in Comp
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Borough Green & Wrotham station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
