What we cannot put right

In fairness, some problems need a different trade:

  • A tray or bath that is cracked
  • Older mastics that may need an asbestos check before removal
  • Water damage behind tiles that needs a tiler

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

Surfaces we seal

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

Remedial sealant in Haslar, done properly

Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. If you have mould trapped under a layer of silicone and smears and lumps from a botched reseal, we can put it right.

In a village or hamlet like Haslar, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

Our work is backed for twelve months.

Signs you need remedial sealant in Haslar

How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.

Keep an eye out for these signs:

  • Over-sealed joints coming away
  • Gaps opening along the back of the worktop
  • Thick, messy sealant smeared over tiles
  • Caulk or the wrong sealant used in a wet area

If you let a flat or house near Portsmouth Harbour station, a joint that keeps failing is best fixed properly while the property is empty.

Questions to ask before booking

  • What the quote includes, VAT included or not
  • Whether all the old sealant comes out first
  • When the joint can take water or movement
  • Who turns up on the day

Can I choose the sealant colour?

Yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.

Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.

Remedial sealant in Haslar: local notes

Haslar is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Haslar has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

For an older house near a landmark such as St Francis, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as Haselworth Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Why act early in Haslar

A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. Older cottages and farmhouses around Haslar can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Why book with us

  • A 12-month guarantee on all work
  • 4.9 on Google from 180+ five-star reviews
  • Sealant colour chosen to suit
  • Neat joints and a tidy finish

Different surfaces, different methods

Leaking trays & enclosures

When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.

Over-sealed & botched joints

Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.

The process

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. For a village or hamlet like Haslar, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We protect the surfaces around the joint.
  2. Every layer of failed sealant is stripped out.
  3. The joint is degreased and checked for movement and leaks.
  4. New sealant goes in once the joint is dry, and is tooled smooth.
  5. You get the cure time and our view on why the joint failed.

Before we arrive

  • Tell us about any water getting in
  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
