How we handle new build mastic in Dumbiedykes
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. If you have beads laid onto grit and dust from the build and gaps between new skirting and floors, we can put it right, on show homes, plot handovers and bathrooms & en suites alike.
Scotland’s cities are still adding new flats and houses, and new-home owners often find sealant snags in the first year or two.
Every job is covered by our one-year guarantee.

Questions from Dumbiedykes
Can you help a landlord with a rental near Edinburgh Waverley station?
Yes, we work for landlords and agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
What guarantee comes with new build mastic in Dumbiedykes?
All our work, in Dumbiedykes and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
How long before the joint can be used?
It depends on the product and the conditions. We tell you how long to leave it before we go.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Where are you based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours in a single home. We will give you a better idea when we quote.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.

Joints and finishes in Dumbiedykes homes
Dumbiedykes is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For new homes near Edinburgh Waverley station, it’s worth checking the sealant early, while snags are still fresh.
Dumbiedykes is about 1 mile east of Edinburgh, in Edinburgh. Anywhere in EH8, we can carry out new build mastic at your property. Across Edinburgh, we cover 175 places, Dumbiedykes among them.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Aftercare tips
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Raise failed sealant with the developer while you’re covered
- Wait for the cure time before using a resealed shower
- Clean sealant with mild detergent, not abrasives
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Dumbiedykes, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know about parking restrictions
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

Signs you need new build mastic in Dumbiedykes
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The problems people usually mention when they call are:
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
- Skirting joints opening in the first winter
In and around Dumbiedykes, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
