About our new build mastic in Bonnyrigg
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. If you are dealing with messy sealant that spoils new finishes and worktop and upstand sealant coming away, we can put it right, whatever the surface.
Many newer Scottish homes have timber frames, which settle as they dry out, so skirting and floor joints can open up in the first year or two, in Bonnyrigg as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Photograph failed sealant before it’s redone
- Get a leaking seal dealt with straight away
- Put sealant faults on your snagging list early
- Wait for the cure time before using a resealed shower
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Movement caused by a poorly fitted tray or bath
- Cracked trays, tiles or worktops
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

There’s no set price list. What we look at:

Advice
Different surfaces, different methods
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
What we are called out for in Bonnyrigg
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Look out for any of the following:
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Frame joints opening as the plaster dries
Around Bonnyrigg, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Whether VAT is included
- Which colour the sealant will be
- What product goes in the joint
- Is the old sealant removed completely?
