About our remedial sealant in Hamister

Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you have gaps opening along the back of the worktop and sealant that came away because the surface wasn’t prepared, we can help.

A bathroom in a place like Hamister gets the same daily wear as one in a city flat. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.

Each job carries a 12-month guarantee, large or small.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Clean sealant with mild products only
  • Don’t wait for a small gap to become a leak
  • Never seal over old silicone
  • Ask why a joint failed before redoing it

Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.

Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

We also work for property managers and facilities teams. Several sites can go on one quote.

How we quote for remedial sealant

Jobs vary more than people expect. The main factors:

  • Any mould that needs treating
  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • When we can work, for business premises

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Helping us quote

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

  • Whether it has been sealed before
  • What’s wrong with the joints now
  • A few photos by email, if you can
  • Where the property is

We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.

Honest limits

We won’t take on work that will not last, so here’s what sealant cannot put right:

  • A tray or worktop that needs refixing first
  • A tray or bath that’s cracked
  • Older mastics that may need an asbestos check before removal

If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Surfaces we seal

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

Signs you need remedial sealant in Hamister

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, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.

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

  • A second bead peeling off the first
  • Wide, uneven beads that look worse than the old ones
  • Movement joints that have split or pulled away
  • Decorators’ caulk around a bath or shower

Whether the job is in Hamister itself or nearby, the right material for each joint matters as much as a neat finish.

What your quote should include

  • How long to leave it before use
  • Are they insured?
  • Whether they seal over old material or remove it
  • Is VAT in the price?

10 questions to ask before booking

Your questions about remedial sealant in Hamister

Is there a guarantee on remedial sealant in Hamister?

All our work, in Hamister and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Is Hamister within the area you cover?

Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.

Do the sealants smell?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Do you do commercial work?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

Can you strip sealant from an acrylic tray safely?

Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that is already there.

How long before the joint can be used?

It depends on the product and the temperature. We tell you how long to leave it before we go.

Can landlords and businesses book you?

Yes. Domestic, commercial and hotel work are all part of what we do.

Can tenants book the work?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

What happens on the day

On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. The work normally takes a few hours for most joints, depending on how much old sealant has to come out. For a place like Hamister, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.

  1. Surrounding tiles, trays and frames are protected first.
  2. The botched or failed sealant is cut away completely.
  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. We give you the cure time and explain what caused the failure.

How to prepare

  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height
  • Try not to wet indoor joints just before the visit

Leave it or put it right?

Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

What you get with us

  • Trusted Arbo and Everbuild sealants
  • We’re fully insured
  • Colour agreed with you before we start
  • Sanitary silicone with an anti-fungal additive in wet areas

What remedial sealant looks like in Hamister

Hamister is close to 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. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out.

Around Hamister, as everywhere, remedial sealant is only as good as the preparation behind it.
