When to call us in Fratton

Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.

These are the problems we’re asked about most:

  • Kitchen joints letting water behind the worktop
  • Thick, messy sealant smeared over tiles
  • A second bead peeling off the first
  • Sealant peeling off a dusty or damp surface

For site and facilities teams at buildings such as Penhale Infant School & Nursery, we reseal washrooms and kitchens in schools and businesses as well as homes.

About our remedial sealant in Fratton

A joint that keeps failing normally has a reason. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. Typical jobs include a shower that leaks however often it’s resealed and beads that never stuck properly, on failed movement joints, leaking tray & enclosure joints and botched or over-sealed joints.

Smaller places like Fratton still have plenty of bathrooms that work hard every day. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.

All our work comes with our one-year guarantee, wherever you are in Portsmouth.

FAQs for Fratton

Do you work for landlords with property near Fratton station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Do you work for hotels and guest houses in Fratton?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Is remedial work guaranteed?

Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.

Can old silicone be taken off without scratching the tiles?

Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. Any existing damage is pointed out before any work starts.

What does remedial sealant cost?

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.

Where is Mr Mastic based?

We’re based in Crawley, and we work across South East England, London and Scotland.

How long does the work take?

Allow a few hours for a typical bath or shower, longer where several layers have been applied. You’ll know the timing when we quote.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Landlord and commercial work in Fratton

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

We also work for property managers and facilities teams in Fratton and across Portsmouth. Several sites can go on one quote, and we’re fully insured.

How the visit works

There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on how many layers have to come out for a typical job. A visit to Fratton is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. Every layer of old sealant is cut and cleaned out.
  3. The joint is cleaned, treated for mould and left to dry.
  4. We use the right backing and sealant for any joint that moves.
  5. Finally we finish the joint and talk you through what we found.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Move anything stored near the joints
  • For business premises, tell us about site rules or sign-in

Advice

Why act early in Fratton

Another bead over the top won’t fix a failed joint. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. In a smaller place like Fratton, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How to look after the new joints

To keep the joints looking good and working properly:

  • Use a soft cloth, not a scourer, on silicone
  • Always have old sealant cut out, not covered
  • Report a tray that rocks or a worktop that lifts
  • Ask why a joint failed before redoing it

Give the new sealant its full cure time: follow the cure time we give you.

Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Older mastics that may need an asbestos check before removal
  • Water damage behind tiles that needs a tiler
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

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

What we seal

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

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

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.

Remedial sealant around Fratton

Fratton is within about 2 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Fratton 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.

In the older streets around St Mary's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Fratton station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.
