Commercial sealant around Colston
In Scotland, private landlords have to meet the Repairing Standard, and keeping sealant sound across a portfolio is part of that.
Community buildings like Colston Wellpark Church are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. Schools such as Bishopbriggs Academy are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.

FAQs for Colston
Can you help a landlord with a rental near Bishopbriggs station?
Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you cover Colston for commercial sealant?
Yes. We work across all of Scotland, and Colston is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you provide RAMS?
Let us know your site’s requirements. We will confirm what we can provide alongside the quote.
Can you start early or work out of hours?
Often, yes. Let us know when the building is quietest, and we will plan the work around them.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
How to look after the new joints
So the new joints stay in good condition:
- Put a squeegee in each shower
- Check extract fans are actually running
- Tell cleaning staff when each room can be used
- Ask cleaners to go gently on the silicone
Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Landlords, agents and businesses in Colston
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours for a single washroom, longer for a whole building for a typical job. Parking in city streets around Colston can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Getting ready for the visit
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
Getting a quote
Every job is quoted individually, so the first step is telling us about yours. Just email us at info@mrmastic.co.uk with the details and send pictures if you have them.

Common problems we fix in Colston
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. Any split there can let water through quickly.
Keep an eye out for any of the following:
- Failed floor-level joints in accessible wet rooms
- Silicone laid over old silicone by a previous contractor
- Rental bathrooms that need resealing between tenants
- Washrooms that need sorting before an inspection

What else we do in Colston
Different surfaces, different methods
Hotel bathrooms
In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
Student & care accommodation
Many accommodation blocks have rows of similar en suites. A room-by-room programme keeps the job efficient.
When something else is needed
To be straight with you, some problems need a different trade:

- A shower tray, bath or basin that is cracked or broken
- Leaking pipework, valves or wastes (a plumber’s job)
