Remedial sealant in Dewartown, done properly
A joint that keeps letting you down needs more than another bead. It helps to have pictures when you drop us a line at info@mrmastic.co.uk, along with when it was last resealed. We work on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant, and common reasons people get in touch are sealant that came away because the surface wasn’t prepared and thick, messy sealant smeared over tiles.
In and around a place like Dewartown, 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 is covered by our 12-month guarantee, wherever you are in Midlothian.

What affects the cost of remedial sealant
Every job gets its own quote. This is what makes a difference:
- How much there is to do
- The product the joint needs
- Working hours on commercial sites
- Mould in or behind the old joints
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- The rough size of the job
- Any previous sealing or DIY work
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
Looking after it afterwards
Aftercare is simple:
- Use a soft cloth, not a scourer, on silicone
- Act on a lifting corner right away
- Ask why a joint failed before redoing it
- Keep an eye on the ceiling below the bathroom
Keep an eye on the joint at first, particularly where the original failure was caused by movement. If anything changes, just email us at info@mrmastic.co.uk.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Dewartown questions

Do you cover Dewartown for remedial sealant?
Yes. Our work covers the whole of Scotland, and Dewartown is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
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.

A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.
What else we do in Dewartown
Bathrooms and kitchens in Dewartown
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out. Private landlords in Scotland must be registered and 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.
For landlords with property near Gorebridge station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What happens if it’s left?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. Outside jobs in Dewartown need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else 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’re working on
- Mention if the joints have been sealed before
How to get a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

Signs you need remedial sealant in Dewartown
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
Common reasons people contact us include:
- Gaps opening along the back of the worktop
- Torn expansion joints
- Mould trapped under a layer of silicone
- Thick, messy sealant smeared over tiles
Managing a site like Newbattle Community High School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

How the job changes by surface
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
