About our remedial sealant in Hersham

Remedial jobs in Hersham 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. We are often asked to deal with products that weren’t meant for the joint and leaks that keep coming back after resealing, across expansion joints, botched or over-sealed joints and failed movement joints.

Around Hersham, you’ll mostly find houses and bungalows, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.

There’s a 12-month guarantee on every job.

Leave it or put it right?

Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around Hersham, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Why book with us

  • We agree the colour with you first
  • Neat joints and a tidy finish
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Arbo and Everbuild products

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. In a smaller place like Hersham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. We look at how the sealant has failed and check for movement or a leak path.
  2. We strip the joint completely, removing any layers below.
  3. Next, any mould is treated and the joint dried.
  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.

How to prepare

  • Let us know about parking restrictions
  • Mention any sign-in or site rules at work premises
  • Let us know if you’ve seen damp or leaks

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

What sealant work cannot fix

It helps to know what we can’t do too:

  • Plumbing leaks behind walls or under trays
  • Sealant in an older building that needs testing for asbestos first
  • Water damage behind tiles that needs a tiler

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.

What we seal

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

Hersham questions

Can you help a landlord with a rental near Walton-On-Thames station?

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

Do you cover smaller places like Hersham?

Yes, Hersham is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can failed expansion joints be resealed?

Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.

How long should I leave it?

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

Can I choose the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few photos.

Is there any odour?

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

Do you have insurance?

Yes. Full insurance covers our work.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Have loose fittings fixed before resealing
  • Keep an eye on the ceiling below the bathroom
  • Find out why the sealant failed first
  • Don’t wait for a small gap to become a leak

Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.

Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.

What affects the quote in Hersham

Every job gets its own quote. This is what makes a difference:

  • Any mould that needs treating
  • Whether old sealant or filler has to be cut out
  • The size of the job
  • Any working-time requirements on site

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • What’s wrong with the joints now
  • How many joints, rooms or windows are involved
  • Photos by email, if that is easy
  • Where the property is

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

Remedial sealant in Hersham: local notes

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

For an older house near a landmark such as Church of St Peter, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Walton-On-Thames station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

When to call us in Hersham

One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.

If you can see any of these, it’s time to have the joints looked at:

  • Caulk or the wrong sealant used in a wet area
  • Gaps opening along the back of the worktop
  • Thick, messy sealant smeared over tiles
  • Dark patches showing through the sealant

Schools such as Bell Farm 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.
