About our commercial sealant in Castlebay
In a hotel, office or washroom, failed sealant is more than an eyesore. Cleaners struggle with it, water gets through it and people notice it. We reseal bathrooms, washrooms, welfare areas and kitchens so they look cared for again. If you have black, stained silicone in guest bathrooms and mouldy bathrooms flagged at a tenancy check, we can help, whatever the surface.
For holiday lets, guest houses and community buildings in or near Castlebay, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All our work comes with our one-year guarantee.

Castlebay: your questions answered
Is there a guarantee on commercial sealant in Castlebay?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Castlebay in your area for commercial sealant?
Yes. We work across all of Scotland, and Castlebay is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Can you reseal hotel rooms while we stay open?
Yes. Rooms are done a few at a time, keeping most rooms available. Housekeeping are told when each room can be let again.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
What commercial sealant looks like in Castlebay
If you run a hotel, guest house or holiday let in a coastal place like Castlebay, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
If you look after a building such as Castlebay Community School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
Castlebay is in Na h-Eileanan Siar. Castlebay gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Castlebay is one of 87 towns and villages in Na h-Eileanan Siar we cover.
We work across HS9 for commercial sealant and the streets around it. Whether your property is on Pier Road and Rathad na Horgh or a nearby road, our applicators can take on the job. We also cover Leideag (1 mile south-east), Bàgh a'Chaisteil (1 mile west), Ceann Tangabhal (1 mile north-west), Brèibhig (1 mile east) and Cuidhir (3 miles north). Island and remote addresses take a little more planning, so tell us where you are when you ask for a quote.
Around Castlebay
Nearby you’ll also find St Brendan's Hospital (under half a mile south-west) and Museum Bharraigh Agus Bhatarsaidh (less than half a mile north-west). Open spaces near Castlebay include Ben Leribreck.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What we do, step by step
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes as long as the scope needs, from one welfare room to a full building for a typical job. Somewhere like Castlebay 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 walk the site with you and agree the rooms, the order and the hours.
- Room by room, we protect the area and remove all the old sealant.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work

Signs you need commercial sealant in Castlebay
Quick fixes come back quickly. New silicone over old, joints that weren’t dried, or an unsuitable product means the joint fails again soon.
If you can see any of these, it’s time to have the joints looked at:
- Whole floors of tired en suites
- Joints that need doing before an inspection or audit
- Washroom sealant that looks dirty however often it’s cleaned
- Split sealant around staff kitchen worktops and sinks
Community buildings like Church of our Lady are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

- What product goes in the joint
- What the quote includes, VAT included or not

How we quote for commercial sealant
There’s no set price list, because no two jobs are the same. What we look at:
- How much there is to do
- Whether there’s mould to deal with
- How easy the joints are to reach
- The number of rooms or windows
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Roughly how big the job is
- Any access issues, like height or stairs
- A few photos by email, if you can
- Where the property is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Landlord and commercial work in Castlebay
For anyone letting property in or around Castlebay, several properties can go on one quote. Send us the addresses and the work at each.
Landlords and agents in Castlebay can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Looking after it afterwards
After the cure time, these simple habits help:
- Check extract fans are actually running
- Encourage users to squeegee shower walls
- Get split or lifting joints looked at early
- Include the silicone on your room checklists
Each room is handed back with its cure time, which is generally around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant is not wetted or scrubbed too soon.
Mould in shared washrooms gets noticed and talked about. The longer it’s left, the deeper it grows into the silicone, so the fix is replacement.
Why deal with it now?
In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. Then two rooms are out of action, not one. A reseal now avoids that. In an older home around Castlebay, damp from a failed joint can get into timber and plaster.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
