Your questions about remedial sealant in Nisbet
Do you cover smaller places like Nisbet?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with remedial sealant in Nisbet?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Remedial sealant in Nisbet, done properly
Remedial jobs in Nisbet normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. Common call-outs are for a second bead peeling off the first and repeat leaks from the same joint, across expansion joints, botched or over-sealed joints and leaking tray & enclosure joints.
In and around a place like Nisbet, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What the job involves on each surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal.
Looking after it afterwards
Looking after new joints is easy:
- Check trays and worktops do not move
- Never seal over old silicone
- Keep bleach and abrasives off the bead
- Keep movement joints clear of mortar and paint
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, drop us a line at info@mrmastic.co.uk.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
What affects the cost of remedial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- Whether there’s mould to deal with
- How many areas need sealing
- Which sealant suits the joint
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Pictures of the joints, sent by email
- The problem you’ve noticed
- The type of property
- Any access issues, like height or stairs

How the visit works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job usually takes a few hours, depending on how many layers have to come out. Outdoor work around Nisbet depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Move anything stored near the joints

Why it’s worth doing now in Nisbet
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Around Nisbet, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Nisbet homes and their sealant
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. 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.
In the older streets around Crailing Parish Church, walls and floors in older homes can move, and sealant and grout show it first.
