About our remedial sealant in Summerston

With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We work on mouldy bath & shower sealant, failed movement joints and botched or over-sealed joints, and common reasons people get in touch are a second bead peeling off the first and dark patches showing through the sealant.

In Scotland’s cities, including the area around Summerston, many older flats had their bathrooms added into small rooms later on. Space is tight and ventilation can be poor, and steam with nowhere to go is what turns sealant black and grout grey.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

FAQs for Summerston

Is Summerston in your area for remedial sealant?

Yes, Summerston is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.

Can a failed shower seal in a tenement flat in Summerston leak into the flat below?

Yes, and the first sign is often a mark on the ceiling below. Cutting out the old sealant and laying a fresh bead puts a stop to it.

Can you fix a reseal that hasn’t worked?

Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, so we find that first.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Can landlords and businesses book you?

Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.

Do you guarantee remedial jobs?

Yes, with our one-year guarantee. If we’ve pointed out another problem, getting it fixed helps the new joint last.

Do you fix expansion and movement joints?

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

What does remedial sealant cost?

It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.

Different surfaces, different methods

Worktops & kitchens

If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, and we’ll tell you if we find it.

Leaking trays & enclosures

If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We’ll tell you what we find.

How we quote for remedial sealant

Your quote is based on your job. We look at:

  • The number and length of the joints
  • Access and height
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Helping us quote

To help us quote quickly, let us know:

  • Whether it’s a home or a business
  • Where the job is, and your postcode

What we’re called out for in Summerston

Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.

People usually contact us after spotting one of these:

  • Movement joints that have split or pulled away
  • Beads that never stuck properly
  • Dark patches showing through the sealant
  • Products that weren’t meant for the joint

If you let a flat or house near Summerston station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Remedial sealant in Summerston: local notes

Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that does not dry out. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.

Schools such as John Paul Academy are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY sealant or a professional job?

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.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. Our tips:

  • Clean sealant with mild products only
  • Keep the room well ventilated
  • Do not wait for a small gap to become a leak
  • Get the cause of a repeat leak found before resealing

If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.

Signs to act on: 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 happens on the day

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours, depending on how many layers have to come out from start to finish. Parking in city streets around Summerston can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.

  1. The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. We reseal with a product suited to the joint, backed where needed.
  5. The joint is tooled and you are told about anything else we found.

How to prepare

  • On commercial sites, let us know about site rules
  • Mention if the joints have been sealed before
  • Keep children and pets away from the work area
