New Build Mastic in Niddrie
Problem with your new-build sealant joints in Niddrie? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.

About our new build mastic in Niddrie
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on kitchens, skirting & floors and windows & doors, and common reasons people get in touch are joints pulling apart as timber shrinks and cracked sealant around new window and door frames.
Scotland’s cities are still adding new flats and houses, and in new homes, sealant and floor joints are often among the first snags.
Our work is backed for twelve months.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. Inside a flat in Niddrie, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
- Tell us if parking is tricky

How to look after the new joints
Aftercare is simple:
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Record problems with dated photos
- Act quickly if a seal starts to leak
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
New homes and floors in Niddrie
Niddrie is close to 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For new homes near Brunstane station, it’s worth checking the sealant early, while snags are still fresh.

Common problems we fix in Niddrie
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Most people get in touch when they notice one of these:
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
- Cracked sealant around new window and door frames
In and around Niddrie, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- When the joint can take water or movement
- What guarantee comes with the work
- What product goes in the joint
- Whether they seal over old material or remove it
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
When it is not the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Structural cracks in walls or ceilings
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.

Questions from Niddrie
Can you do new build mastic in Niddrie?

Can I send you my snagging list?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
How long does new build mastic take?
That depends on the amount of work, but most jobs take a few hours in a single home. We’ll give you a better idea when we quote.

What do you need from me for a quote?
