Remedial sealant & repairs in Sandwick, Na h-Eileanan Siar
Removing failed, mouldy or leaking sealant and putting it right in Sandwick, with a one-year guarantee on every job. Ask us for a quote.
- Caulk or the wrong sealant used in a wet area
- Beads that never stuck properly
- Movement joints that have split or pulled away
When to call us in Sandwick
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing sets the depth and stops that.
People normally contact us after spotting one of these:
- Thick, messy sealant smeared over tiles
- Sealant that came away because the surface wasn’t prepared
- Products that weren’t meant for the joint
- Leaks that keep coming back after resealing
Around Sandwick, as everywhere, remedial sealant is only as good as the preparation behind it.

How we handle remedial sealant in Sandwick
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We work on failed movement joints, expansion joints and shrunken worktop sealant, and people most often call us about a shower that leaks however often it’s resealed and caulk or the wrong sealant used in a wet area.
A bathroom in a place like Sandwick gets the same daily wear as one in a city flat. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Landlord and commercial work in Sandwick
If you manage several properties in or around Sandwick, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Around Sandwick, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

Advice
Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
How we quote for remedial sealant
Jobs vary more than people expect. The main factors:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- The size of the job
- Working hours on commercial sites
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- Whether it has been sealed before
- Any access issues, like height or stairs
- The type of property
- The address or postcode of the job
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, drop us a line at info@mrmastic.co.uk.
Bathrooms and kitchens in Sandwick
Sandwick is within about 1 mile of 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. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
Homes close to Stornoway High Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Older mastics that may need an asbestos check before removal
- Failed tanking or loose tiles behind the sealant
- A leaking trap, valve or supply pipe
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.
Where we work in Sandwick
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Failed movement joints
- Expansion joints
How to look after the new joints
To keep the joints looking good and working properly:
- Keep bleach and abrasives off the bead
- Deal with small splits early
- Keep an eye on the ceiling below the bathroom
- Air the bathroom so the sealant can dry
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just email us at info@mrmastic.co.uk.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
