How the job changes by surface
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and point out any existing damage.
Remedial sealant for homes and businesses in Riverhead
Remedial jobs in Riverhead generally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. If you are dealing with repeat leaks from the same joint and smears and lumps from a botched reseal, we can put it right.
Smaller places like Riverhead still have plenty of bathrooms that work hard every day. Older or newer, every room gets the same approach: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
There’s a 12-month guarantee on every job.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- Cracks in the fitting rather than the joint
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
Surfaces we seal
- Botched or over-sealed joints

Quotes for remedial sealant in Riverhead
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- Whether there’s mould to deal with
- Whether the work is at height
- Any working-time requirements on site
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The address or postcode of the job
- A few pictures by email, if you can
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or email us.
Landlord and commercial work in Riverhead
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most joints, depending on how much old sealant has to come out. Parking around Riverhead is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can

Advice
Riverhead questions
Do you cover smaller places like Riverhead?
Yes, Riverhead is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Sevenoaks station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
Is remedial work guaranteed?
Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.
My shower still leaks after a reseal. Can you sort it?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.

Remedial sealant in Riverhead: local notes
There are hotels and other places to stay in and around Riverhead. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you let a flat or house near Sevenoaks station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you live in an older home near Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant. Managing a site like Amherst School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep an eye on the ceiling below the bathroom
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
- Run the fan after every shower
Clean gently: no scraping, scouring pads or harsh chemicals.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
Can I do it myself?
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 fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
