Prestongrange: your questions answered
Do you cover Prestongrange for remedial sealant?
Yes, Prestongrange is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Can you help a landlord with a rental near Prestonpans station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price 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.
Do you guarantee remedial jobs?
Yes. You get our 12-month guarantee, and we’re fully insured.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
How we handle remedial sealant in Prestongrange
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. Typical jobs include worktop sealant that has shrunk and split and products that weren’t meant for the joint, across failed movement joints, expansion joints and leaking tray & enclosure joints.
A bathroom in a place like Prestongrange 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Act on a lifting corner straight away
- Keep the room well ventilated
- Keep movement joints clear of mortar and paint
- Keep bleach and abrasives off the bead
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.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

Prestongrange homes and their sealant
Prestongrange 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. But mould still grows into sealant and grout in a room that does not dry out.
If you live in an older home near Prestongrange Parish Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as Preston Lodge High School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Letting a property close to Prestonpans station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- On commercial sites, let us know about site rules
- Mention any tricky access
- Let us know about parking restrictions

Helping us quote
Photos help, but a description is a good start. Please mention:
- The problem you’ve noticed
- The address or postcode of the job
- If someone has resealed it before
- Whether it’s a home or a business
We quote each job on its own, so the first step is telling us about yours. Simply email us at info@mrmastic.co.uk and describe the job.
What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- A bath, tray or worktop that moves until it’s properly fixed
- Cracks in the fitting rather than the joint
- Older mastics that may need an asbestos check before removal
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Mouldy bath & shower sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Expansion joints
- Botched or over-sealed joints
- Shrunken worktop sealant
How the job changes by surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before we reseal.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Landlord and commercial work in Prestongrange
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
