New build mastic for homes and businesses in Queensferry
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. Typical jobs include internal frame sealant that has split and gaps behind new kitchen upstands, across skirting & floors, plot handovers and windows & doors.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere like Queensferry may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- 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.
- We check every joint and leave you with the cure times.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Your questions about new build mastic in Queensferry
Is Queensferry within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Queensferry in your area for new build mastic?
Yes, Queensferry is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear quote.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before any work starts.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
When something else is needed
It helps to know what we cannot do:
- Damaged fittings that need replacing
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Do not wait for the house to settle if water is getting through
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
What we’re called out for in Queensferry
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
The most common problems we see are:
- Gaps opening as the house dries out and settles
- Cracked sealant around new window and door frames
- Sealant work across a run of new homes
- Kitchen sealant that has pulled off the wall
For new homes near Dalmeny station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- Which sealant they’ll use, and why
- How long to leave it before use
- How the surfaces are prepared before sealing
- Whether you can choose the colour

How we quote for new build mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- The size of the job
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What we need to know
When you contact us, it’s useful to know:
- The address or postcode of the job
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, email us at info@mrmastic.co.uk.
What new build mastic looks like in Queensferry
Queensferry is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
Around Queensferry, as everywhere, new build mastic is only as good as the preparation behind it.

Different surfaces, different methods
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
