About our remedial sealant in Dalserf
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We’re often asked to deal with products that weren’t meant for the joint and gaps opening along the back of the worktop, across mouldy bath & shower sealant, expansion joints and leaking tray & enclosure joints.
Bathrooms in smaller places like Dalserf work just as hard as those in the cities. 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.

When to call us in Dalserf
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Signs it’s time to call us include:
- Sealant peeling off a dusty or damp surface
- Mould trapped under a layer of silicone
- Worktop sealant that has shrunk and split
- Repeat leaks from the same joint
If you look after a building such as Larkhall Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before booking
- How much experience the applicator has
- Whether the sealant suits the joint
- How the colour is chosen
- How long the guarantee is
What remedial sealant looks like in Dalserf
Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies. 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.
Homes close to Dalserf Kirk include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near Larkhall station, botched sealant from a previous quick fix is easier to strip out between tenants.

What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours, depending on how many layers have to come out. Outdoor work around Dalserf depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- 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.
Before we arrive
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Questions from Dalserf
Do you cover smaller places like Dalserf?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do remedial sealant in Dalserf?
Yes, Dalserf is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Landlord and commercial work in Dalserf
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
How to look after the new joints
Looking after new joints is easy:
- Ask why a joint failed before redoing it
- Never seal over old silicone
- Have loose fittings fixed before resealing
- Never fill a movement joint with mortar or grout
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.

DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What affects the cost of remedial sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- Which sealant suits the joint
- Working hours on commercial sites
- The old material and how stubborn it is
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Roughly how big the job is
- Any previous sealing or DIY work
- How we’d reach the joints
- Where the job is, and your postcode
There’s no standard price list. Instead, we give you a clear price for your job. To get started, email us at info@mrmastic.co.uk.

Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
