Remedial sealant in Black Crofts, done properly

Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you have caulk or the wrong sealant used in a wet area and worktop sealant that has shrunk and split, we can put it right.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Remedial sealant in Black Crofts: local notes

Black Crofts 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. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.

For landlords with property near Connel Ferry station, botched sealant from a previous quick fix is easier to strip out between tenants.

Black Crofts is about 40 miles north-west of Helensburgh, in Argyll and Bute. Wherever you are in the PA37 postcode area, we can carry out remedial sealant at your property. Our Argyll and Bute coverage runs to 118 places, and Black Crofts is one of them. For nearby work, see our Glasgow page.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Do you need remedial sealant in Black Crofts?

Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.

Signs it’s time to call us include:

  • Sealant applied over old sealant that has lifted
  • Thick, messy sealant smeared over tiles
  • Sealant peeling off a dusty or damp surface
  • Decorators’ caulk around a bath or shower

In the older streets around Ardchattan Parish Church, walls and floors in older homes can move, and sealant and grout show it first.

How to look after the new joints

Looking after new joints is easy:

  • Clean sealant with mild products only
  • Get the cause of a repeat leak found before resealing
  • Act on a lifting corner straight away
  • Never fill a movement joint with mortar or grout

Do not let anyone seal over it later. New silicone doesn’t bond to old, so the old bead should always come out first.

Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.

What the job involves on each surface

Mouldy bath & shower sealant

Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.

Windows & doors

Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.

How it works

There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours, depending on how many layers have to come out from start to finish. Around Black Crofts, distance and access matter more than parking. Tell us how to find the property and how to reach the work.

  1. First we find out how and where the joint has failed.
  2. All the old sealant comes out, including any layers underneath.
  3. Next, any mould is treated and the joint dried.
  4. Moving joints get backing and a flexible sealant to suit.
  5. The new joint is tooled neatly and we explain anything else we found.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can

Related advice

Should I try it myself first?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Common questions in Black Crofts

Is Black Crofts in your area for remedial sealant?

Yes. Our work covers the whole of Scotland, and Black Crofts is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.

Do you work for landlords with property near Connel Ferry station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.

Can you reseal a split movement joint?

Yes. Backing sets the depth and stops the sealant sticking to the back.

Yes. Every job comes with our 12-month guarantee.

Are you ARBOMaster approved?

Yes. We’re an ARBOMaster approved applicator.

What if resealing will not fix my leak?

Then we explain what we have found. You may need a plumber or bathroom fitter.

How long should I leave it?

Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.

Can I choose the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Why act early in Black Crofts

DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
