How we handle new build mastic in Dornock
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. If you are dealing with gaps behind new kitchen upstands and plot mastic for developers ahead of handover, we can help, whatever the surface.
For a place like Dornock, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why it’s worth doing now in Dornock
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. In a place like Dornock, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What affects the quote in Dornock
Your quote is based on your job. We take into account:
- The old material and how stubborn it is
- The number and length of the joints
- The number of rooms or windows
- Access and height
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that is easy
- Where the property is
- The problem you’ve noticed
- Roughly how big the job is
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, email us at info@mrmastic.co.uk.
Work for landlords, hotels and businesses
Letting agents and landlords in Dornock can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Different surfaces, different methods
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.

Can you help a landlord with a rental near Annan station?

What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
What colour sealant will you use?

Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Dornock, along with the rest of our area.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can and we’ll give you a quote. We’ll flag anything that needs another trade.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Is it worth resealing while the house is still settling?
Any seal that is leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Outdoor work around Dornock depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked for movement before any work starts.
- 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.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
- Mention any parking rules near the property
Getting a quote
Getting a quote is simple: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will come back to you with a quote.

Common problems we fix in Dornock
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
It’s worth asking for a quote if you see:
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
- Frame joints opening as the plaster dries
- Skirting joints opening in the first winter
For new homes near Annan station, it’s worth checking the sealant early, while snags are still fresh.

Joints and finishes in Dornock homes
Dornock is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Around Dornock, as everywhere, new build mastic is only as good as the preparation behind it.
