About our new build mastic in Rosemount
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you’re dealing with plot mastic for developers ahead of handover and new-build shower sealant that has already split, we can help, on show homes, plot handovers and skirting & floors alike.
Older tenement flats generally have timber floors on joists, so skirting joints open and close through the year. For a flat in Rosemount, a flexible sealant copes with that movement where filler would crack.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
How to look after the new joints
After the cure time, these simple habits help:
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Do not wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.

New build mastic in Rosemount: local notes
Rosemount 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. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For new homes near Aberdeen station, it’s worth checking the sealant early, while snags are still fresh.

Rosemount: your questions answered
Is new build mastic in Rosemount guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Rosemount for new build mastic?
Yes. We work across all of Scotland, and Rosemount is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope and we’ll quote.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Rosemount and the rest of Aberdeen.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Why act early in Rosemount
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Wind-driven rain gets into any failed joint on the outside of a city building, and in Rosemount, damp can spread through stone and plaster before anyone sees it.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

When to call us in Rosemount
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Keep an eye out for these signs:
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
- Gaps opening as the house dries out and settles
- Untidy sealant flagged on a snagging list
Around Rosemount, as everywhere, new build mastic is only as good as the preparation behind it.

How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. For a tenement in Rosemount, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
