New build mastic for homes and businesses in Dolphinton
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. Typical jobs include new-build shower sealant that has already split and beads laid onto grit and dust from the build, on plot handovers, skirting & floors and kitchens.
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.
There’s a 12-month guarantee on every job.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Check bath and shower seals every few months as the house settles
- Record problems with dated photos
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
New build mastic in Dolphinton: local notes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
Whether the job is in Dolphinton itself or nearby, the right material for each joint matters as much as a neat finish.

Common questions in Dolphinton
What guarantee comes with new build mastic in Dolphinton?
All our work, in Dolphinton and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like Dolphinton?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
For landlords and businesses
For anyone letting property in or around Dolphinton, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Why deal with it now?
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can send an email to info@mrmastic.co.uk with a few photos. In a place like Dolphinton, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Surface by surface
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
What we do, step by step
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 in a single home. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
How to get a quote
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we will come back to you with a quote.
Related advice
Do you need new build mastic in Dolphinton?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Any of these means the joints need attention:
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
- Sealant applied over dusty or wet surfaces
Around Dolphinton, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
- What the quote includes, VAT included or not
- Who turns up on the day
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
