Remedial sealant in Dormans Park
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. Common call-outs are for gaps opening along the back of the worktop and products that weren’t meant for the joint, on botched or over-sealed joints, failed movement joints and expansion joints.
Being in a small place like Dormans Park makes no difference to the job itself: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Every job comes with our one-year guarantee, wherever you are in West Sussex.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Different surfaces, different methods
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Dormans Park, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Common questions in Dormans Park
I let a flat near Dormans station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Is Dormans Park in your area for remedial sealant?
Yes, Dormans Park is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Is remedial work guaranteed?
Yes. Every job comes with our one-year guarantee.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How long does remedial resealing take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours.
Why act early in Dormans Park
Stripping out botched sealant adds time to a reseal, but rarely a lot: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. 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 Dormans Park, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Dormans Park homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Homes close to St John the Evangelist include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Schools such as Bush Davies School of Theatre Arts are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Dormans station, botched sealant from a previous quick fix is easier to strip out between tenants.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check ceilings under showers for marks
- Do not add new sealant on top of old
- Keep the room well ventilated
- Get the cause of a repeat leak found before resealing
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
