What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. In a city area like The Grange, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

About our new build mastic in The Grange
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you have smeared, uneven beads picked up at snagging and sealant applied over dusty or wet surfaces, we can help, whatever the surface.
Scotland’s cities are still adding new flats and houses, and new-home owners often find sealant snags in the first year or two, in The Grange as anywhere.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why it’s worth doing now in The Grange
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Scottish rain finds any gap around a frame or wall joint, and in The Grange, damp can spread through stone and plaster before anyone sees it.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

What new build mastic looks like in The Grange
The Grange is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Edinburgh Waverley station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Different surfaces, different methods
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
When something else is needed
We will always be straight with you, so here’s what new sealant won’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Damaged fittings that need replacing
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.
Joints and surfaces we work on

Common problems we fix in The Grange
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Signs it’s time to call us include:
- Kitchen sealant that has pulled off the wall
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
Around The Grange, as everywhere, new build mastic is only as good as the preparation behind it.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Open a window or run the fan after bathing
- Don’t wait for the house to settle if water is getting through
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
