Do you fix expansion and movement joints?

About our remedial sealant in Colston
Remedial jobs in Colston normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. If you’re dealing with gaps opening along the back of the worktop and torn expansion joints, we can put it right, on shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant alike.
Scotland’s cities have a lot of flats, from sandstone or granite tenements to modern blocks, as well as houses in the suburbs. Scottish water is generally soft, so limescale is less of a problem than in hard-water areas, but mould still grows into sealant and grout in a steamy bathroom.
You get a one-year guarantee, the same in Colston as everywhere else we work.

What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Colston, damp can travel a long way before it shows.

How the job changes by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the 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.
When to call us in Colston
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that came away because the surface wasn’t prepared
- Products that weren’t meant for the joint
- Black mould underneath the bead
- Thick, messy sealant smeared over tiles
Managing a site like Bishopbriggs Academy? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Quotes for remedial sealant in Colston
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether the work is at height
- The old material and how stubborn it is
- The type of sealant required
- The size of the job
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
When you call or email, these details help:
- Where the job is, and your postcode
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
For a quote, email us at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
Looking after it afterwards
So the new joints stay in good condition:
- Get the cause of a repeat leak found before resealing
- Keep movement joints clear of mortar and paint
- Have loose fittings fixed before resealing
- Air the bathroom so the sealant can dry
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Remedial sealant around Colston
In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in. 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.
If you let a flat or house near Bishopbriggs station, a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as Colston Wellpark Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What’s near Colston
Locally, jobs take us to homes and businesses close to Springburn Park, among other places. For rail, the closest station is Bishopbriggs station, roughly 0.5 miles north-east of the centre. A little further out are Chinatown (2.3 miles south-west) and Bishop's Castle (2.5 miles south). Green spaces nearby include Lenzie Moss and Hogganfield Loch.
What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on how many layers have to come out for a typical job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Colston, it helps to know the floor, the door entry arrangements and the nearest parking.
- 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.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
