New-build mastic & snagging in Douglas, Dundee
Specialist new build mastic for Douglas: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Gaps between new skirting and floors
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Do not seal over failed sealant yourself
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
New build mastic for homes and businesses in Douglas
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have gaps between new skirting and floors and plot mastic for developers ahead of handover, we can put it right.
New flats and houses are still being built in and around Scotland’s cities, and in new homes, sealant and floor joints are often among the first snags.
Big or small, it’s backed by our one-year guarantee in Douglas and across Dundee.

New build mastic in Douglas: local notes
Douglas is within about 1 mile of 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 Broughty Ferry station, it’s worth checking the sealant early, while snags are still fresh.
Douglas is about 2 miles west of Broughty Ferry, in Dundee. Douglas gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. We cover 50 towns and villages across Dundee.

FAQs for Douglas
What guarantee comes with new build mastic in Douglas?
All our work, in Douglas and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do new build mastic in Douglas?
Yes. Our work covers the whole of Scotland, and Douglas is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
How long does new build mastic take?
That depends on how much there is to do, but as a guide it takes a few hours in a single home. We’ll give you a better idea when we quote.
Why does sealant fail so quickly in new builds?
It’s common, and there are usually two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Get in touch with the number of plots and the scope and we will quote.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
When to call us in Douglas
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
The problems people normally mention when they call include:
- Sealant applied over dusty or wet surfaces
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
- Messy sealant that spoils new finishes
In and around Douglas, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
- When the joint can take water or movement
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
Why it’s worth doing now in Douglas
A hairline gap at a skirting can wait, but water getting through cannot. If you’re unsure which you have, send an email to info@mrmastic.co.uk with pictures. Private landlords in Douglas must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
