About our remedial sealant in Shirley

Remedial jobs in Shirley normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints, and the jobs we see most are sealant that came away because the surface wasn’t prepared and sealant applied over old sealant that has lifted.

Smaller places like Shirley still have plenty of bathrooms that work hard every day. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.

Big or small, it’s backed by our 12-month guarantee.

Remedial sealant in Shirley: local notes

Shirley is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Shirley has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.

If you live in an older home near Shirley Parish Church, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Millbrook (Hants) station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

How the visit works

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours, depending on how many layers have to come out, depending on how much there is to do. In a smaller place like Shirley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  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. Moving joints get backing and a flexible sealant to suit.
  5. We tool the joint and tell you about anything else that needs attention.

Before we arrive

  • Mention any parking rules near the property
  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts

Related advice

Should I try it myself first?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

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.

What we’re called out for in Shirley

How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing sets the depth and stops that.

Signs it’s time to call us include:

  • Torn expansion joints
  • Dark patches showing through the sealant
  • Decorators’ caulk around a bath or shower
  • Smears and lumps from a botched reseal

Managing a site like Wordsworth Primary School? Then 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.

Questions to ask before you book

  • Whether all the old sealant comes out first
  • What product goes in the joint
  • How long to leave it before use
  • Whether you can choose the colour

Choosing a sealant specialist

Surface by surface

Over-sealed & botched joints

Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, then reseal neatly.

Movement & expansion joints

A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.

Why deal with it now?

It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Around Shirley, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

Why us?

  • Colour agreed with you before any work starts
  • Full insurance on every job
  • An ARBOMaster approved applicator
  • Homes, businesses and hotels

See our cost guide and customer reviews.

Honest limits

We’ll always be straight with you, so here’s what sealant can’t fix:

  • Older mastics that may need an asbestos check before removal
  • Cracks in the fitting rather than the joint
  • Failed tanking or loose tiles behind the sealant

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

What we seal

  • Botched or over-sealed joints
  • Leaking tray & enclosure joints

What affects the quote in Shirley

Some jobs are bigger than they look, and some smaller. The main factors:

  • When we can work, for business premises
  • The number of rooms or windows
  • Whether there’s mould to deal with
  • The old material and how stubborn it is

Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.

Helping us quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • The problem you’ve noticed
  • Where the property is
  • Whether it has been sealed before
  • If it’s domestic, commercial or a hotel

Questions from Shirley

Do you work in hotels near Shirley?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Do you work for landlords with property near Millbrook (Hants) station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.

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

Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours.

Does someone need to be in?

It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Will there be a smell?

It depends on the product. Some products have a noticeable smell, others very little.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

Are you insured?

Yes. Mr Mastic is fully insured.
