How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Never seal over old silicone
  • Don’t wait for a small gap to become a leak
  • Never fill a movement joint with mortar or grout
  • Report a tray that rocks or a worktop that lifts

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

A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.

Remedial sealant in Gosport

Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we will tell you rather than reseal something that will not fix it. We work on failed movement joints, shrunken worktop sealant and mouldy bath & shower sealant, and the jobs we see most are mould trapped under a layer of silicone and gaps opening along the back of the worktop.

Homes around Gosport are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.

All our work is covered by a one-year guarantee.

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.

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.

Common problems we fix in Gosport

All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.

People usually contact us after spotting one of these:

  • Torn expansion joints
  • Mould trapped under a layer of silicone
  • Over-sealed joints coming away
  • Gaps opening along the back of the worktop

For site and facilities teams at buildings such as Ampfield Church of England Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Before you book anyone

  • Is the old sealant removed completely?
  • Who turns up on the day
  • Whether you can choose the colour
  • Whether the sealant suits the joint

Our hiring checklist

How the job changes by surface

Leaking trays & enclosures

Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.

Movement & expansion joints

Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.

Common questions in Gosport

Is Gosport within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Chandlers Ford station?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Can I do it myself?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Are you ARBOMaster approved?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

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

Allow a few hours, depending on how many layers have to come out. We will give you a timescale when we quote.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Is there any odour?

There can be a smell while the sealant cures. Ventilation helps.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

What happens on the day

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Gosport, access is often the only tricky part. 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. 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.

Preparing for the visit

  • Keep children and pets away from the work area
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about stairs, lifts or work at height

What remedial sealant looks like in Gosport

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.

Homes close to Church of St Mark include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to Chandlers Ford station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Quotes for remedial sealant in Gosport

The quote reflects the job in front of us. We look at:

  • Working hours on commercial sites
  • The number and length of the joints
  • Which sealant suits the joint
  • Whether there’s mould to deal with

What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • What’s wrong with the joints now
  • The type of property
  • If someone has resealed it before
  • Roughly how big the job is

What happens if it’s left?

Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Gosport can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
