Washroom sealing across Colston
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Colston is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- We clean and dry every surface so the new sealant can grip.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Rooms reopen after the product’s cure time, and we move to the next.
Preparing the site
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed

Washroom sealing for commercial buildings in Colston
When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. Site teams most often ask us about washrooms that look worn because of the sealant and split or peeling sealant at shower trays, across vanity units and basins, urinals and WCs and showers, trays and wet room floors. A specialist sealant contractor works differently from a general builder: in Colston, that means joint design, primers and backing rod as standard.

Why act early in Colston
Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Around smaller places like Colston, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Why us?
- A range of standard colours, depending on the product
- Specification-led, product-correct work

How the quote is worked out

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Sending details for a quote
Whether it’s one area or a whole building, these details speed things up:
- Access details, including height
- Photos of the joints, close up and from further back
- Whether the building will be occupied during the work
- Any dates the work must fit around
To get a fixed quote, speak to us on 01277 525 020 or email us. You can also send details through our quote form.
When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- A room that stays damp because ventilation isn’t working
- Hollow tiles or loose panels behind the joint
Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly before you book.
Surfaces we seal
- Vanity units and basins
- Urinals and WCs
- Kitchens and tea points
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Showers, trays and wet room floors
Wet areas in Colston’s workplaces
Colston is on Scotland’s wetter western side. In a damp climate, washrooms that aren’t well ventilated stay wet for longer, and sealant in a room that never dries out moulds faster.
Toilets at places like St Rollox Business and Retail Park, 1.7 miles south of Colston, are cleaned constantly, so silicone needs to be sound and smooth. For a site such as Stobhill Hospital, which lies south-east of Colston, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. At a university such as Glasgow Caledonian University, which lies south of Colston, summer is the usual window for resealing residence bathrooms.

Your questions answered

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work around term dates at a campus such as Glasgow Caledonian University?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you do washroom sealing in healthcare settings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.
When can showers be used after new sealant?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so there are always rooms open.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is there a guarantee on the work?
Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
