Remedial sealant for homes and businesses in St Andrews
A joint that keeps failing normally has a reason. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. We work on mouldy bath & shower sealant, failed movement joints and botched or over-sealed joints, and common reasons people get in touch are decorators’ caulk around a bath or shower and movement joints that have split or pulled away.
In and around a place like St Andrews, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Your questions about remedial sealant in St Andrews
I let a flat near Leuchars station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Do you work for hotels and guest houses in St Andrews?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours, and we confirm the time with your quote.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Leave it or put it right?
Mould under a bead cannot be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. In a place like St Andrews, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Homes and businesses are quoted the same way: 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 will explain what it covers.

Different surfaces, different methods
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. We will reseal and tell you if extraction looks to be the issue.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, letting the sealant flex between the two faces.
What affects the quote in St Andrews
Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- The size of the job
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- A few pictures by email, if you can
- The problem you’ve noticed
- The address or postcode of the job
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
What we do, step by step
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Around St Andrews, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us if parking is tricky
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

DIY versus a professional finish
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, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
St Andrews homes and their sealant
St Andrews is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. There are hotels and other places to stay in and around St Andrews. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Rented homes near Leuchars station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as St Andrews, older homes can move a little, which is hard on rigid grout and tired sealant. Schools such as Madras College are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Air the bathroom so the sealant can dry
- Use a soft cloth, not a scourer, on silicone
- Do not point over movement joints
- Find out why the sealant failed first
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just drop us a line at info@mrmastic.co.uk.
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.
