Why act early in Dalkeith
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. If you live in a flat in Dalkeith, failed sealant can send water to the neighbours below, which turns a small job into a bigger one.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

New build mastic for homes and businesses in Dalkeith
We work in new homes and on new-build sites across Dalkeith. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on kitchens, plot handovers and skirting & floors, and people most often call us about new-build shower sealant that has already split and plot mastic for developers ahead of handover.
Commercial units and shops in a town like Dalkeith have floors with joints that need resealing as they wear. Sealing them before the edges break up saves a bigger repair.
Each job carries a 12-month guarantee, whatever its size.

- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep photos and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
- Look at the sealant regularly in the first couple of years
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. Parking around Dalkeith is rarely difficult, though older streets in the centre can be tight. If you are in a flat with a shared stair or a door entry system, let us know when you book.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Clear the area around the work

Dalkeith questions
Do you work for landlords with property near Eskbank station?
Yes. We work for landlords and letting agents as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Can you do new build mastic in Dalkeith?
Yes. We work across all of Scotland, and Dalkeith is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
How long does the job take?
As a guide, most jobs take a few hours in a single home. Larger jobs naturally take longer.
Can I do 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.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What new build mastic looks like in Dalkeith
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

Common problems we fix in Dalkeith
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The problems people generally mention when they call are:
- Beads laid onto grit and dust from the build
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
- Leaking shower tray seals in a new home
For new homes near Eskbank station, it’s worth checking the sealant early, while snags are still fresh.
