How we handle remedial sealant in Bower Heath

A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We’re often asked to deal with caulk or the wrong sealant used in a wet area and beads that never stuck properly, on shrunken worktop sealant, mouldy bath & shower sealant and botched or over-sealed joints.

Being in a small place like Bower Heath makes no difference to the job itself: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Why it’s worth doing now in Bower Heath

Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. Around Bower Heath, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. Somewhere like Bower Heath needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Old beads and residue are removed down to clean surfaces.
  3. Mould is treated and the joint dried.
  4. We reseal with a product suited to the joint, backed where needed.
  5. The joint is tooled and you’re told about anything else we found.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before
  • Try not to wet indoor joints just before the visit

Questions from Bower Heath

Will you come out to Bower Heath?

Yes. Bower Heath is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you cover Bower Heath for remedial sealant?

Yes. Our work covers London and the South East, and Bower Heath is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

What does remedial sealant cost?

It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.

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 sealant that is been put over old sealant?

Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.

Are you an approved applicator?

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

When to call us in Bower Heath

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 is too stiff or too thin.

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

  • Floor or wall movement joints that have failed
  • Dark patches showing through the sealant
  • Leaks that keep coming back after resealing
  • Kitchen joints letting water behind the worktop

Managing a site like Sauncey Wood Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Before booking anyone

  • How long the guarantee is
  • Who does the work, and how experienced they are
  • How long to leave it before use
  • How the surfaces are prepared before sealing

Choosing a sealant specialist

Bathrooms and kitchens in Bower Heath

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For landlords with property near Harpenden station, botched sealant from a previous quick fix is easier to strip out between tenants. In the older streets around All Saints, walls and floors in older homes can move, and sealant and grout show it first.

Bower Heath gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

Surface by surface

Worktops & kitchens

Kitchen joints hold grease and residue, so we spend extra time cleaning before resealing.

Movement & expansion joints

Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal.

What we can’t put right

Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:

  • Tiles that have come away from the wall
  • Cracks in the fitting rather than the joint
  • Plumbing leaks behind walls or under trays

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Joints and surfaces we work on

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

Landlords, agents and businesses in Bower Heath

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Landlords and agents in Bower Heath can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Looking after it afterwards

A little care helps the new joints last. Our advice:

  • Check trays and worktops do not move
  • Clean sealant with mild products only
  • Never seal over old silicone
  • Don’t point over movement joints

Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.

Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
