What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours, depending on how many layers have to come out, depending on how much there is to do. For a job in St Leonards, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Mention any tricky access
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

Remedial sealant in St Leonards, done properly
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints, and the jobs we see most are beads that never stuck properly and sealant applied over old sealant that has lifted.
In a smaller place like St Leonards, homes are mostly houses and bungalows rather than flats, some older and some much newer. Sealant and grout wear out here just as they do in a big town.
Your job is guaranteed for a year, as with all our work.

How the job changes by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. We will reseal and tell you if extraction looks to be the issue.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
Why act early in St Leonards
Another bead over the top won’t fix a failed joint. It does not grip the old layer, leaving the leak in place and one more layer to cut out later. In a smaller place like St Leonards, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Doing several joints on one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Bathrooms and kitchens in St Leonards
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to All Saints include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Schools such as St Ives Primary & Nursery School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Someone resealed my shower and it’s leaking again. Can you help?
Yes. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Aftercare tips
Looking after new joints is easy:
- Use a soft cloth, not a scourer, on silicone
- Find out why the sealant failed first
- Keep movement joints clear of mortar and paint
- Air the bathroom so the sealant can dry
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old.
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.
When it is not the sealant
A few problems are outside what sealant work can do:
- A leaking trap, valve or supply pipe
- Movement from fittings that aren’t supported
- Cracks in the fitting rather than the joint
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.
