Hamnavoe: your questions answered
Is commercial sealant in Hamnavoe guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Hamnavoe in your area for commercial sealant?
Yes, Hamnavoe is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Where are you based?
We work from Crawley. We cover Hamnavoe and the rest of the Shetland Islands, along with the rest of our area.
How we handle commercial sealant in Hamnavoe
Guest bathrooms are cleaned every day and used by different people every night, so sealant wears out faster than it would at home. Rooms are resealed in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. If you have washrooms that need sorting before an inspection and worktop sealant that has shrunk and stained, we can help, whatever the surface.
In a smaller place like Hamnavoe, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. All of them have washrooms, kitchens and fire-rated joints that need looking after.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Do you need commercial sealant in Hamnavoe?
Commercial buildings settle and move with temperature, and stud walls move more than solid ones. Joints between different materials take the strain until it tears.
These are the problems we are asked about most:
- Leaking joints in shower rooms and changing areas
- Sealant failing again soon after quick repairs
- Joints that need doing before an inspection or audit
- Mouldy washroom sealant that staff and guests notice
Whether the job is in Hamnavoe itself or nearby, the right material for each joint matters as much as a neat finish.

How the visit works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours per room, so whole buildings are phased in most cases. Around Hamnavoe, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
How to prepare
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Advice
Keeping the joints in good condition
Looking after new joints is easy:
- Keep strong chemicals and scourers off the joints
- Check the joints during routine room inspections
- Give housekeeping the cure time for every room
- Log resealing so you know what’s due
We give a cure time for every area we finish, normally around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
A room that can’t be let or used is lost income. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.
