Alexandria questions
Is Alexandria within the area you cover?
Yes, Alexandria is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Alexandria station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long does the job take?
Typically it takes as long as the scope needs, from one welfare room to a full building. Bigger jobs take longer, and we’ll say how long yours will take.
Can you start early or work out of hours?
It can be arranged for many jobs. The hours are agreed before work starts.
Can I choose the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Commercial sealant for homes and businesses in Alexandria
In a hotel, office or washroom, failed sealant is more than an eyesore. It’s a cleaning problem, a leak risk and something guests and staff notice. We reseal bathrooms, washrooms, welfare areas and kitchens so they look cared for again. If you have black, stained silicone in guest bathrooms and split sealant around staff kitchen worktops and sinks, we can help.
For holiday lets, guest houses and community buildings in or near Alexandria, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
Whatever the size of the job, it’s backed by our one-year guarantee.

Why deal with it now?
Before an inspection, audit or busy season, sealant is easy to overlook. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

- Over 20 years’ experience
- Arbo and Everbuild products

Commercial sealant in Alexandria: local notes
Private landlords in Scotland must meet the Repairing Standard, so landlords with several properties often need sealant work across them all.
Community buildings like St Andrew's Parish Church are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. For site and facilities teams at buildings such as Vale of Leven Academy, washroom and kitchen sealant can be programmed around term times or opening hours.

How to look after the new joints
Looking after new joints is easy:
- Leave squeegees in busy showers
- Act on lifting sealant before it leaks
- Keep strong chemicals and scourers off the joints
- Give housekeeping the cure time for every room
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
Black sealant in a staff washroom or guest bathroom draws complaints. The longer it’s left, the deeper it grows into the silicone, so the fix is replacement.
How it works
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a morning for a small washroom, and a planned programme for bigger sites, depending on the size of the job. For a place like Alexandria, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we visit and agree the scope, the sequence and the working hours.
- Every area is sheeted and the old silicone stripped out.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- We check every room and give its cure time for housekeeping.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- Clear the area around the work

When to call us in Alexandria
Wet rooms and accessible showers are designed for the whole floor to get wet, so the joints at floor level are under water often. Any split there can let water through quickly.
It’s worth asking for a quote if you see:
- Mouldy bathrooms flagged at a tenancy check
- Shower leaks reaching the floor below
- Split sealant where wet room floors meet walls
- Sealant failing again soon after quick repairs

- Which colour the sealant will be

Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. It won’t solve:
- Poor ventilation that keeps bringing mould back
- Tiles coming off the wall
- Certifying fire stopping or building compliance
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
