Remedial sealant in Galashiels, done properly
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you have a second bead peeling off the first and torn expansion joints, we can put it right, whatever the surface.
Scottish towns like Galashiels tend to mix older stone-built streets, harled houses and newer estates. Whatever the age of the house, sealant and grout wear out in the end.
All our work comes with our 12-month guarantee.

What affects the cost of remedial sealant
Call for a quick quote. The main things that affect it are:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The old material and how stubborn it is
- Working hours on commercial sites
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
Helping us quote
To make quoting easier, let us know:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Roughly how big the job is
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.
What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. In Galashiels, wind and rain soon get through failed outside joints. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What you get with us
- A sealant colour to suit the surroundings
- You choose the colour before work begins
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When something else is needed
We won’t take on work that will not last, so here’s what sealant can’t put right:
- A bath, tray or worktop that moves until it’s properly fixed
- Sealant in an older building that needs testing for asbestos first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Galashiels, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
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
- Clear the area around the work

What remedial sealant looks like in Galashiels
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. But mould still grows into sealant and grout in a room that doesn’t dry out.

Do you need remedial sealant in Galashiels?
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing sets the depth and stops that.
These are the problems we’re asked about most:
- A shower that leaks however often it’s resealed
- Mould trapped under a layer of silicone
- Gaps opening along the back of the worktop
- A second bead peeling off the first
For site and facilities teams at buildings such as Galashiels Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.
