Aftercare tips
Once the sealant has cured, a few habits help it last:
- Use a soft cloth, not a scourer, on silicone
- Never fill a movement joint with mortar or grout
- Air the bathroom so the sealant can dry
- Do not wait for a small gap to become a leak
Keep the room ventilated: run the fan during and after showers, or open a window.
Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
FAQs for Rayne
Do you cover smaller places like Rayne?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Braintree station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you guarantee remedial jobs?
Yes. Every job comes with our 12-month guarantee.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
Are you fully insured?
Yes. We are fully insured.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Do you need remedial sealant in Rayne?
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
These are the problems we are asked about most:
- Torn expansion joints
- Dark patches showing through the sealant
- Sealant applied over old sealant that has lifted
- Wide, uneven beads that look worse than the old ones
For landlords with property near Braintree station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Questions to ask before booking
- Is the old sealant removed completely?
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
- What preparation is included
How the job changes by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal with a low-modulus product.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
How we quote for remedial sealant
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- Whether the work is at height
- The type of sealant required
- Whether there’s mould to deal with
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- The type of property
- Roughly how big the job is
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Can I do it myself?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What else we do in Rayne
Why deal with it now?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Where a wall is exposed, as many are in small places like Rayne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like Rayne, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
How to prepare
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
