Remedial sealant for homes and businesses in Upper Coll
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you are dealing with a shower that leaks however often it’s resealed and sealant that came away because the surface wasn’t prepared, we can help, whatever the surface.
In and around a place like Upper Coll, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Every job comes with a 12-month guarantee, wherever you are in Na h-Eileanan Siar.

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How the job changes by surface
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We will tell you what we find.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
What affects the cost of remedial sealant
We don’t publish a price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- Whether the work is at height
- Working hours on commercial sites
- Mould in or behind the old joints
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before work begins.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- How many joints, rooms or windows are involved
- The type of property
- Where the job is, and your postcode
- Whether it has been sealed before

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Use a soft cloth, not a scourer, on silicone
- Act on a lifting corner right away
- Have loose fittings fixed before resealing
- Keep movement joints clear of mortar and paint
Leave the new joint to cure fully before it gets wet or moves: normally around 24 hours, or as long as we advise.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
Bathrooms and kitchens in Upper Coll
Upper Coll is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
In and around Upper Coll, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

FAQs for Upper Coll
Is Upper Coll within the area you cover?
Yes. Upper Coll is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole 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.
What guarantee comes with remedial sealant in Upper Coll?
All our work, in Upper Coll and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
Getting a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Related advice
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
Do you need remedial sealant in Upper Coll?
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Signs it’s time to call us include:
- Sealant that came away because the surface wasn’t prepared
- Worktop sealant that has shrunk and split
- Over-sealed joints coming away
- Smears and lumps from a botched reseal
For jobs in and around Upper Coll, choosing the right material for each joint is as important as a tidy finish.
