Remedial sealant for Keynor Estate homes and businesses

Common problems we fix in Keynor Estate

A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.

These are the problems we’re asked about most:

  • Floor or wall movement joints that have failed
  • Wide, uneven beads that look worse than the old ones
  • Repeat leaks from the same joint
  • Over-sealed joints coming away

Schools such as Sidlesham Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Our hiring checklist

Remedial sealant in Keynor Estate, done properly

If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. Typical jobs include leaks that keep coming back after resealing and worktop sealant that has shrunk and split, on failed movement joints, expansion joints and botched or over-sealed joints.

Somewhere as small as Keynor Estate, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Bathrooms and kitchens in Keynor Estate

Keynor Estate is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.

If you live in an older home near St Mary Our Lady Sidlesham, older homes can move a little, which is hard on rigid grout and tired sealant. For landlords with property near Chichester station, a joint that keeps failing is best fixed properly while the property is empty.

DIY sealant or a professional job?

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.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • A cracked shower tray or bath (that needs repair or replacing)
  • Failed tanking or loose tiles behind the sealant
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Where we work in Keynor Estate

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

How we quote for remedial sealant

The quote reflects the job in front of us. We take into account:

  • Whether the work is at height
  • Working hours on commercial sites
  • Whether there’s mould to deal with
  • Which sealant suits the joint

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

What we need to know

What to tell us when you ask for a quote:

  • What’s wrong with the joints now
  • The rough size of the job
  • Access, such as stairs, a lift or height
  • The address or postcode of the job

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work before giving you a price.

Keynor Estate questions

Is Keynor Estate within the area you cover?

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

Can you help a landlord with a rental near Chichester station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.

Someone resealed my shower and it’s leaking again. Can you help?

Yes. We will take all the sealant out, look for why it failed and reseal it properly.

How long before the joint can be used?

Different products cure at different speeds, so please follow the time we give you.

Does remedial work come with a guarantee?

Yes. Remedial work carries the same 12-month guarantee as all our work.

How long will it take to strip and reseal the joint?

A little longer than a standard reseal. For most joints, it’s a few hours.

Is there any odour?

It depends on the product. Some products have a noticeable smell, others very little.

Can you work on commercial sites?

Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Deal with small splits early
  • Always have old sealant cut out, not covered
  • Keep an eye on the ceiling below the bathroom
  • Never fill a movement joint with mortar or grout

Where we’ve pointed out another fault, have it put right, or the new joint may fail again.

If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.

Why it’s worth doing now in Keynor Estate

Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Older cottages and farmhouses around Keynor Estate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Why us?

  • Tidy, careful work
  • One-year guarantee on every job
  • Homes, businesses and hotels
  • Old sealant always removed completely

What happens on the day

Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Keynor Estate, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we find out how and where the joint has failed.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. The new joint is tooled neatly and we explain anything else we found.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Mention any parking rules near the property
  • Plan for the work area to be out of bounds to pets and children
