Remedial sealant for homes and businesses in Port Glasgow
A movement joint stops working when its sealant splits or sets hard. 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 botched or over-sealed joints, mouldy bath & shower sealant and shrunken worktop sealant, and people most often call us about gaps opening along the back of the worktop and torn expansion joints.
Homes in a town like Port Glasgow range from flats in older buildings to family houses on newer estates. The jobs are much the same in all of them: mouldy beads, gaps where a bath has moved and grout that’s cracked or stained.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. In a Scottish town like Port Glasgow, parking is normally straightforward, though older centres can be tighter. For flats, mention the shared stair or door entry system.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Keep children and pets away from the work area

Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Remedial sealant in Port Glasgow: local notes
Port Glasgow is within about 1 mile of 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. Private landlords in Scotland must be registered and 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.
Homes close to Clune Park Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.

What if the leak is not the sealant?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
Is there any odour?

Common problems we fix in Port Glasgow
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
Most people get in touch when they notice something like this:
- Mould trapped under a layer of silicone
- Torn expansion joints
- Products that weren’t meant for the joint
- Repeat leaks from the same joint
Rented homes near Port Glasgow station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
What your quote should include
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
- How long the guarantee is
- How hidden problems are handled

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Run the fan after every shower
- Clean sealant with mild products only
- Report a tray that rocks or a worktop that lifts
- Do not point over movement joints
Give the new sealant its full cure time: follow the cure time we give you.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
