Remedial sealant in Kennington, done properly

A joint that keeps letting you down needs more than another bead. Send photos when you ring 0345 464 0079 or email us, along with when it was last resealed. Typical jobs include black mould underneath the bead and worktop sealant that has shrunk and split, across shrunken worktop sealant, botched or over-sealed joints and failed movement joints.

Homes around Kennington range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.

All our work is covered by a 12-month guarantee.

Questions from Kennington

Do you work for landlords with property near Ashford International station?

Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Do you cover smaller places like Kennington?

Yes, Kennington is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Will there be a smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Are you ARBOMaster approved?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can I choose the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

How long should I leave it?

It depends on the product and the conditions. We tell you how long to leave it before we go.

Can you remove old sealant without damaging the bath?

Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. We point out any damage that is already there.

Should I try DIY first?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Common problems we fix in Kennington

Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.

The problems people normally mention when they call are:

  • Worktop sealant that has shrunk and split
  • Caulk or the wrong sealant used in a wet area
  • Repeat leaks from the same joint
  • Wide, uneven beads that look worse than the old ones

Letting a property close to Ashford International station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why it’s worth doing now in Kennington

Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Homes in smaller places like Kennington can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • We never seal over old sealant

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. For a job in Kennington, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. All the old sealant comes out, including any layers underneath.
  3. Next, any mould is treated and the joint dried.
  4. We use the right backing and sealant for any joint that moves.
  5. The new joint is tooled neatly and we explain anything else we found.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we’re working on
  • Keep pets and children clear of the area while we work

Advice

Different surfaces, different methods

Over-sealed & botched joints

A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.

Worktops & kitchens

If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, and we will tell you if we find it.

Kennington homes and their sealant

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. Kennington has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

For site and facilities teams at buildings such as Kennington Church of England Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of St Mary include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

When something else is needed

New sealant can’t fix everything, and we will tell you before work begins. Sealant won’t put right:

  • Water damage behind tiles that needs a tiler
  • Plumbing leaks behind walls or under trays
  • A tray or bath that is cracked

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Where we work in Kennington

  • Mouldy bath & shower sealant
  • Leaking tray & enclosure joints
  • Shrunken worktop sealant
  • Failed movement joints
  • Expansion joints
  • Botched or over-sealed joints

What affects the quote in Kennington

There’s no set price list. What we look at:

  • Working hours on commercial sites
  • The product the joint needs
  • How many areas need sealing
  • Access and height

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What we need to know

Photos help, but a description is a good start. Please mention:

  • How we’d reach the joints
  • Pictures of the joints, sent by email
  • The address or postcode of the job
  • The type of property

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.

Can I do it myself?

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.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
