How we handle remedial sealant in Heriot
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and botched or over-sealed joints, and the jobs we see most are repeat leaks from the same joint and floor or wall movement joints that have failed.
For a place like Heriot, the job is the same as anywhere: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
Every job is covered by our 12-month guarantee.

What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. In an older home around Heriot, damp from a failed joint can get into timber and plaster.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Remedial sealant around Heriot
In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out.
For jobs in and around Heriot, choosing the right material for each joint is as important as a tidy finish. Around Heriot, as everywhere, remedial sealant is only as good as the preparation behind it.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Your questions about remedial sealant in Heriot
Is there a guarantee on remedial sealant in Heriot?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Heriot?
Yes, Heriot is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, normally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many layers have to come out. 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.
- 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.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Tell us about any water getting in

Advice
What affects the quote in Heriot
For a quick quote, just ask. The main things that affect it are:
- How easy the joints are to reach
- When we can work, for business premises
- How many areas need sealing
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Photos by email, if that’s easy
Getting a quote is simple: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.
Surface by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Deal with small splits early
- Look for stains below bathrooms now and then
- Run the fan after every shower
- Never fill a movement joint with mortar or grout
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
