Remedial sealant for homes and businesses in Whiteley

Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. We’re often asked to deal with caulk or the wrong sealant used in a wet area and movement joints that have split or pulled away, on failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints.

Around Whiteley, you’ll mostly find houses and bungalows, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.

Our work is backed for twelve months, in Whiteley and everywhere else we cover.

Can I do it myself?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

The process

There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. For a job in Whiteley, 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 look at how the sealant has failed and check for movement or a leak path.
  2. Every layer of old sealant is cut and cleaned out.
  3. We clean the joint, treat any mould and let it dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. The new joint is tooled neatly and we explain anything else we found.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Tell us if parking is tricky
  • Keep children and pets away from the work area

Landlord and commercial work in Whiteley

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

How we quote for remedial sealant

We do not publish a price list, because jobs vary so much. What we look at:

  • Whether old sealant or filler has to be cut out
  • How many areas need sealing
  • The amount of work
  • Any mould that needs treating

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What we need to know

When you call or email, these details help:

  • What’s wrong with the joints now
  • Where the job is, and your postcode
  • If someone has resealed it before
  • How we’d reach the joints

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, call 0345 464 0079 or email us.

Remedial sealant in Whiteley: local notes

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.

Managing a site like Whiteley Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For an older house near a landmark such as St Margaret Mary, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Swanwick station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How the job changes by surface

Windows & doors

Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.

Over-sealed & botched joints

Every layer has to come out, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • Do not add new sealant on top of old
  • Keep an eye on the ceiling below the bathroom
  • Keep the room well ventilated
  • Do not wait for a small gap to become a leak

Keep the room ventilated: use the extractor or open a window after showering.

Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.

What sealant work cannot fix

We will not take on work that will not last, so these are the limits:

  • A leaking trap, valve or supply pipe
  • A bath, tray or worktop that moves until it’s properly fixed
  • Tiles that have come away from the wall

If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Surfaces we seal

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

Common questions in Whiteley

Is Whiteley within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do remedial sealant in Whiteley?

Yes. We work across London and the South East, and Whiteley is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned.

How long should I leave it?

Cure times vary by product and the conditions. We tell you how long to leave it before we go.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Someone sealed over the old bead. Can you fix it?

Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s what makes the new bead last.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme.

Will you leave a mess?

Tidy work is part of the job. We protect what’s around the joints.
