Why it’s worth doing now in Horndean
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Black mould and gaps in sealant do not fix themselves, and in a busy home in Horndean they get worse with every use. Replacing the sealant now is the simplest fix.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

How we handle remedial sealant in Horndean
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that’s what we find, we will tell you rather than reseal something that won’t fix it. Typical jobs include products that weren’t meant for the joint and wide, uneven beads that look worse than the old ones, on leaking tray & enclosure joints, botched or over-sealed joints and expansion joints.
Horndean mixes older houses with estates built more recently, and bathrooms range from decades-old suites to brand-new ones. Whatever their age, sealant and grout tend to go before anything else.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Horndean, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- 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.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Always have old sealant cut out, not covered
- Keep bleach and abrasives off the bead
- Don’t point over movement joints
- Look for stains below bathrooms now and then
Do not let anyone seal over it later. New silicone does not bond to old.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
How the job changes by surface
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, which we’ll point out.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Horndean questions
Is Horndean in your area for remedial sealant?
Yes. Our work covers London and the South East, and Horndean is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Can you help a landlord with a rental near Rowlands Castle station?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you fix a reseal that hasn’t worked?
Yes, generally. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
What if resealing won’t fix my leak?
We check for that before we reseal. If the fault is elsewhere, you’ll know before any work is done.
Can you remove sealant that is been put over old sealant?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
Signs you need remedial sealant in Horndean
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
Most people get in touch when they notice one of these:
- Floor or wall movement joints that have failed
- Wide, uneven beads that look worse than the old ones
- A shower that leaks however often it’s resealed
- Mould trapped under a layer of silicone
Schools such as Horndean Technology College are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
Bathrooms and kitchens in Horndean
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Rowlands Castle station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near Saint Wilfrid's, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
