Remedial sealant in Alexandria, done properly

Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. If you’re dealing with kitchen joints letting water behind the worktop and black mould underneath the bead, we can help, on expansion joints, mouldy bath & shower sealant and failed movement joints alike.

Bathrooms in smaller places like Alexandria work just as hard as those in the cities. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.

There’s a 12-month guarantee on every job, whatever its size.

Remedial sealant around Alexandria

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. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.

Letting a property close to Alexandria station? Then botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as St Andrew's Parish Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

When to call us in Alexandria

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

Keep an eye out for any of the following:

  • Wide, uneven beads that look worse than the old ones
  • Torn expansion joints
  • Beads that never stuck properly
  • Worktop sealant that has shrunk and split

Managing a site like Vale of Leven Academy? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Our hiring checklist

Why deal with it now?

Remedial work takes longer than a straight reseal, but not by much: the work takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Why us?

  • Colour agreed with you before we start
  • Approved under the ARBOMaster scheme
  • More than 20 years in sealant work
  • Every job guaranteed for a year

What we do, step by step

You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. Around Alexandria, distance and access matter more than parking. Let us know how to find you and how to reach the joints.

  1. The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
  2. Old beads and residue are removed down to clean surfaces.
  3. We treat any mould and dry the joint thoroughly.
  4. The right product goes in, with backing where the joint moves.
  5. The joint is tooled and you are told about anything else we found.

Preparing for the visit

  • Let us know about parking restrictions
  • Try not to wet indoor joints just before the visit
  • Mention if the joints have been sealed before

Surface by surface

Movement & expansion joints

Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.

Over-sealed & botched joints

A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, then reseal neatly.

Should I try it myself first?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
