About our remedial sealant in Hamnavoe
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. We are often asked to deal with over-sealed joints coming away and beads that never stuck properly, across shrunken worktop sealant, leaking tray & enclosure joints and botched or over-sealed joints.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Where a building moves, cracked grout and split sealant are generally the first signs.

What affects the quote in Hamnavoe
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- The number and length of the joints
- How many areas need sealing
- Any working-time requirements on site
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
What we need to know
Photos help, but a description is a good start. Please mention:
- The address or postcode of the job
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Landlords, agents and businesses in Hamnavoe
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
For anyone letting property in or around Hamnavoe, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Around Hamnavoe, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Tiles that have come away from the wall
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Expansion joints
- Failed movement joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Remedial sealant around Hamnavoe
Hamnavoe is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Island jobs need planning around ferries and the weather, so the more notice, the better.
In and around Hamnavoe, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
Hamnavoe is in the Shetland Islands. If you need remedial sealant in Hamnavoe, it’s easy to get a quote: please send an email to info@mrmastic.co.uk. We are based in Crawley and cover the Shetland Islands, Hamnavoe included. Hamnavoe is one of 63 towns and villages in the Shetland Islands where we work for remedial sealant.
Here we cover the ZE2 postcode area for remedial sealant. Local streets include Glenburn Road, Atlaness and Gudda Taing, all of which we cover. Close by, we work in Toogs (1 mile south), Scalloway (3 miles north-east), Gulberwick (5 miles east), Cunningsburgh (5 miles south-east) and Bremirehoull (6 miles south-east). Further out, we also cover Lerwick (7 miles north-east), Sound (6 miles north-east) and Sandwick (8 miles south-east). As one of the bigger places in the Shetland Islands, Hamnavoe has homes, rented property and businesses of every kind. For island and remote addresses, a little more planning is needed, so mention it when you ask for a quote.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep the room well ventilated
- Clean sealant with mild products only
- Keep an eye on the ceiling below the bathroom
- Don’t add new sealant on top of old
Where we have pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Your questions about remedial sealant in Hamnavoe
Is Hamnavoe in your area for remedial sealant?
Yes, Hamnavoe is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Will you come out to Hamnavoe?
Yes, Hamnavoe is covered. We work across all of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you need remedial sealant in Hamnavoe?
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
It’s worth asking for a quote if you see:
- Over-sealed joints coming away
- Leaks that keep coming back after resealing
- Beads that never stuck properly
- Movement joints that have split or pulled away
For jobs in and around Hamnavoe, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- What product goes in the joint
- How long the guarantee is
