New-build mastic & snagging in Macmerry, East Lothian
New build mastic across Macmerry and nearby, with old sealant always removed completely.
- Gaps between new skirting and floors
- Second-fix sealing on new plots
- Beads laid onto grit and dust from the build
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
New build mastic for homes and businesses in Macmerry
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. Common call-outs are for kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles, across show homes, plot handovers and skirting & floors.
For a place like Macmerry, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
You get a one-year guarantee, the same in Macmerry as everywhere else we work.

Joints and finishes in Macmerry homes
Macmerry is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
In and around Macmerry, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Longniddry station, it’s worth checking the sealant early, while snags are still fresh.

Leave it or put it right?
A hairline gap at a skirting can wait, but water getting through cannot. If you are unsure which you have, email us at info@mrmastic.co.uk with pictures. In a place like Macmerry, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
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 and we’ll give you an honest view and a quote.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Watch for new gaps as the house dries out
- Record problems with dated pictures
- Open a window or run the fan after bathing
- Raise failed sealant with the developer while you are covered
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Early snagging is easier snagging. Small faults turn into leaks if left.
Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.
We also work for property managers and facilities teams in Macmerry and across East Lothian. We can quote a run of properties together, and we are fully insured for the work.

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 anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Move anything stored near the joints
