DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
About our new build mastic in Downfield
We work in new homes and on new-build sites across Downfield. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. Typical jobs include plot mastic for developers ahead of handover and sealant applied over dusty or wet surfaces, on bathrooms & en suites, plot handovers and kitchens.
Offices, shops and commercial units in Scotland’s cities have floors with movement joints and thresholds that take heavy wear. In Downfield, we cover those floor joints as well as plot mastic for developers.
You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. In a city area like Downfield, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish.
Can you quote for more than one area?

Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
What we can’t put right
We’ll always be straight with you, so here’s what sealant cannot fix:
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

Do you need new build mastic in Downfield?
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Keep an eye out for these signs:
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
In and around Downfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic around Downfield
Downfield 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.
