FAQs for Ashgill
Is Ashgill in your area for remedial sealant?
Yes, Ashgill is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Ashgill?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you offer different sealant colours?
Normally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
Can I do 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.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
How long does remedial resealing take?
That depends on how many layers there are and how many joints. You’ll have a timescale before any work begins.
Remedial sealant for homes and businesses in Ashgill
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. We are often asked to deal with dark patches showing through the sealant and kitchen joints letting water behind the worktop, across botched or over-sealed joints, shrunken worktop sealant and failed movement joints.
In and around a place like Ashgill, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.

Work for landlords, hotels and businesses
If you manage several properties in or around Ashgill, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Letting agents and landlords in Ashgill can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Get the cause of a repeat leak found before resealing
- Don’t point over movement joints
- Report a tray that rocks or a worktop that lifts
- Run the fan after every shower
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start.
Don’t keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.

Different surfaces, different methods
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
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.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How it works
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on how many layers have to come out. Somewhere like Ashgill may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it 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 if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.

Remedial sealant in Ashgill: 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 doesn’t 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.
If you live in an older home near Dalserf Kirk, walls and floors in older homes can move, and sealant and grout show it first. If you look after a building such as Larkhall Academy, 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. For landlords with property near Larkhall station, a joint that keeps failing is best fixed properly while the property is empty.

What affects the quote in Ashgill
We do not publish a price list, because no two jobs are the same. What we look at:
- The old material and how stubborn it is
- The number of rooms or windows
- The size of the job
- The product the joint needs
Combining jobs into one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.
What we need to know
Photos help, but a description is a good start. Please mention:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work and give you a clear price.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- A leaking trap, valve or supply pipe
- A cracked shower tray or bath (that needs repair or replacing)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.
