Landlord and commercial work in Sandwick
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
How the job changes by surface
Student & care accommodation
In care settings, we agree the order and timings with staff, and staff are told when each bathroom can be used.
Office washrooms & kitchens
Staff toilets, washrooms and kitchens get constant use, so we can work early or out of hours where that can be arranged. Basins, urinals, worktops and sinks are all resealed.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning for a small washroom, and a planned programme for bigger sites. For a place like Sandwick, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
Before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
How to get a quote
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Related advice
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Common problems we fix in Sandwick
Staff kitchens and food areas see constant splashing and wiping, and grease and cleaning sprays break down sealant. The worktop and sink edges usually fail first.
Most people get in touch after spotting one of these:
- Silicone laid over old silicone by a previous contractor
- Black, stained silicone in guest bathrooms
- Joints that need doing before an inspection or audit
- Failed floor-level joints in accessible wet rooms
In and around Sandwick, as anywhere, good commercial sealant starts with a clean, dry, properly prepared joint.
What to look for in a quote
- When the joint can take water or movement
- Are they insured?
- What guarantee comes with the work
- Which colour the sealant will be
Why it’s worth doing now in Sandwick
Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, keeping disruption down and costs clear. Around Sandwick, water from a failed joint in an older stone home can soak into timber and plaster.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What you get with us
- More than 20 years in sealant work
- Experience in homes, commercial sites and hotels
- Colour agreed with you before work begins
- Any old sealant cut out fully, not covered over

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Include the silicone on your room checklists
- Book larger programmes for quieter times of year
- Act on lifting sealant before it leaks
- Keep strong chemicals and scourers off the joints
A squeegee in each shower is a simple help: less water sits on the joints between uses.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.

Questions from Sandwick
Is Sandwick within the area you cover?
Yes. Sandwick is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Is Sandwick in your area for commercial sealant?
Yes. We work across all of Scotland, and Sandwick is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Can you take on a whole building?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you reseal between tenancies?
Yes. We reseal bathrooms and kitchens in rented homes, and we can quote for several addresses at once.
Is commercial work guaranteed?
Yes. Our one-year guarantee covers commercial work too.
Can you reseal hotel rooms while we stay open?
Yes. We agree the room order and times with your managers, and you will know when each room can be used.
What commercial sealant looks like in Sandwick
If you run a hotel, guest house or holiday let in a coastal place like Sandwick, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Private landlords in Scotland must meet the Repairing Standard, so landlords with several properties often need sealant work across them all.
If you look after a church, hall or community building such as Stornoway High Church, any kitchen and washrooms need the same sealant care as any other building.
