Remedial sealant & repairs in Hillswick, Shetland Islands
Remedial sealant across Hillswick and nearby, with old sealant always removed completely and a 12-month guarantee.
- Caulk or the wrong sealant used in a wet area
- Dark patches showing through the sealant
- Leaks that keep coming back after resealing
How we handle remedial sealant in Hillswick
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. If you have beads that never stuck properly and sealant applied over old sealant that has lifted, we can put it right, whatever the surface.
Bathrooms in smaller places like Hillswick work just as hard as those in the cities. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Surface by surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, and then we reseal it neatly.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Hillswick: your questions answered
Do you cover Hillswick for remedial sealant?
Yes. We work across all of Scotland, and Hillswick is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is there a guarantee on remedial sealant in Hillswick?
All our work, in Hillswick and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you remove sealant that is been put over old sealant?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What remedial sealant looks like in Hillswick
Hillswick is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
If you live in an older home near Northmavine Parish Church and Churchyard, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Hillswick is in the Shetland Islands. Wherever you are in the ZE2 postcode area, we can carry out remedial sealant at your property. Our the Shetland Islands coverage runs to 63 places, Hillswick among them.

What else we do in Hillswick
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours, depending on how many layers have to come out. Outside jobs in Hillswick need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions

Advice
Do you need remedial sealant in Hillswick?
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
Common reasons people contact us include:
- A shower that leaks however often it’s resealed
- Movement joints that have split or pulled away
- Thick, messy sealant smeared over tiles
- Dark patches showing through the sealant
Around Hillswick, as everywhere, remedial sealant is only as good as the preparation behind it.
