Remedial sealant in Ashwell End, done properly
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We are often asked to deal with sealant that came away because the surface wasn’t prepared and torn expansion joints, on shrunken worktop sealant, botched or over-sealed joints and failed movement joints.
Being in a small place like Ashwell End makes no difference to the job itself: the journey and access are simply agreed in advance. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
All our work is covered by a 12-month guarantee.

How the visit works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. Somewhere like Ashwell End needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We protect the surfaces around the joint.
- 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.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Let us know about parking restrictions

Advice
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into 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.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Deal with small splits early
- Don’t point over movement joints
- Find out why the sealant failed first
- Report a tray that rocks or a worktop that lifts
Give the new sealant its full cure time: generally around 24 hours, or as long as we advise.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
What affects the cost of remedial sealant
The price is agreed before any work begins. It’s based on:
- The old material and how stubborn it is
- Whether the work is at height
- The number of rooms or windows
- The product the joint needs
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
To help us quote quickly, let us know:
- Where the property is
- The rough size of the job
- Any access issues, like height or stairs
- Any previous sealing or DIY work
For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
Why deal with it now?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Where a wall is exposed, as many are in small places like Ashwell End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

When to call us in Ashwell End
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Signs it’s time to call us include:
- Movement joints that have split or pulled away
- Mould trapped under a layer of silicone
- Caulk or the wrong sealant used in a wet area
- Over-sealed joints coming away
Letting a property close to Ashwell & Morden station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

What remedial sealant looks like in Ashwell End
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.
If you look after a building such as Ashwell Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around St Mary's Church, walls and floors in older homes can move, and sealant and grout show it first.
