How we quote for remedial sealant
You’ll get a clear quote before we start. It’s based on:
- How many areas need sealing
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Whether the work is at height
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Any access issues, like height or stairs
- Roughly how big the job is
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work.
About our remedial sealant in Haster
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. We work on leaking tray & enclosure joints, failed movement joints and expansion joints, and the jobs we see most are leaks that keep coming back after resealing and products that weren’t meant for the joint.
Bathrooms in smaller places like Haster 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When something else is needed
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)
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on

- Mouldy bath & shower sealant

- Shrunken worktop sealant
Bathrooms and kitchens in Haster
Haster is within about 3 miles 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. Failed sealant around a bath or shower is worth sorting between tenancies.
Letting a property close to Wick station? Then a joint that keeps failing is best fixed properly while the property is empty.

Near you in Haster
Haster’s nearest station is Wick station, about 2.1 miles east of the centre. A little further out are Wick Town and County Hospital (2.3 miles east) and Castle of Old Wick (3.1 miles south-east). Not far away are Loch Hempriggs.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
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.
Why deal with it now?
Another bead over the top will not fix a failed joint. It does not grip the old layer, so the leak carries on and there’s now more to remove. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

How the visit works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. Outdoor work around Haster depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints

Is Haster in your area for remedial sealant?
Yes, Haster is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.

What if the leak is not the sealant?
Then we explain what we have found. You may need a plumber or bathroom fitter.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can you remove old sealant without damaging the bath?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. Any existing damage is pointed out before work begins.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
How do I get a quote for remedial sealant in Haster?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you remove sealant that is been put over old sealant?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Surface by surface
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
When to call us in Haster
Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
Keep an eye out for these signs:
- A shower that leaks however often it’s resealed
- Worktop sealant that has shrunk and split
- Sealant applied over old sealant that has lifted
- Wide, uneven beads that look worse than the old ones
Managing a site like Wick High School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
