How we handle remedial sealant in Walston
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. If you have movement joints that have split or pulled away and a second bead peeling off the first, we can help, on mouldy bath & shower sealant, failed movement joints and shrunken worktop sealant alike.
For a place like Walston, the job is the same as anywhere: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
Every job is covered by a 12-month guarantee, wherever you are in South Lanarkshire.

What the job involves on each surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal.
Why it’s worth doing now in Walston
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In an older home around Walston, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Walston questions
Do you cover Walston for remedial sealant?
Yes, Walston is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you cover smaller places like Walston?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can old silicone be taken off without scratching the tiles?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. We point out any damage that is already there.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.

How it works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit
- Clear the area around the work

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Remedial sealant in Walston: local notes
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. 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 includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies.
In the older streets around Walston Parish Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. In and around Walston, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Have loose fittings fixed before resealing
- Never fill a movement joint with mortar or grout
- Don’t wait for a small gap to become a leak
- Clean sealant with mild products only
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
