Remedial Sealant in Glenlochar
We cover Glenlochar for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Sealant that came away because the surface wasn’t prepared
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
Landlords, agents and businesses in Glenlochar
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Remedial sealant in Glenlochar
Movement and expansion joints fail when the sealant cannot stretch. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. We work on leaking tray & enclosure joints, failed movement joints and mouldy bath & shower sealant, and the jobs we see most are wide, uneven beads that look worse than the old ones and gaps opening along the back of the worktop.
Being further from a city doesn’t change the work: old material out, joints cleaned and dried, and a fresh, even finish. We just plan the journey and access beforehand.
You get a one-year guarantee, the same in Glenlochar as everywhere else we work.

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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Remedial sealant in Glenlochar: local notes
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. 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. Failed sealant around a bath or shower is worth sorting between tenancies.
Managing a site like Castle Douglas High 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.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask why a joint failed before redoing it
- Don’t point over movement joints
- Deal with small splits early
- Check trays and worktops don’t move
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
How the visit works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job usually takes a few hours, depending on how many layers have to come out. Outdoor work around Glenlochar depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

- Beads that never stuck properly
- Over-sealed joints coming away
- Thick, messy sealant smeared over tiles
- Gaps opening along the back of the worktop

Surface by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal with a low-modulus product.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
