New-build mastic & snagging in New Winton, East Lothian
Plot mastic for developers and snagging failed sealant in new homes for homeowners, landlords and businesses in New Winton. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Joints pulling apart as timber shrinks
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
- Look at the sealant regularly in the first couple of years
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
How we handle new build mastic in New Winton
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you are dealing with kitchen sealant that has pulled off the wall and skirting joints opening in the first winter, we can help, on windows & doors, kitchens and skirting & floors alike.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Common problems we fix in New Winton
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
Common reasons people contact us are:
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
Around New Winton, as everywhere, new build mastic is only as good as the preparation behind it.

Surface by surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Landlord and commercial work in New Winton
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What affects the quote in New Winton
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
What to tell us when you ask for a quote:
- Photos by email, if that’s easy
- Where the job is, and your postcode
- Whether it has been sealed before
- How many joints, rooms or windows are involved
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job.
How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. 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 going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

New homes and floors in New Winton

If you’ve bought a new home near Prestonpans station, the sealant around baths, showers and frames is worth checking in the first year or two.

New Winton: your questions answered
Is New Winton in your area for new build mastic?
Yes. We work across all of Scotland, and New Winton is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
I let a flat near Prestonpans station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with pictures if you can. We will flag anything that needs another trade.
How long does the job take?
That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on the number of plots. We’ll give you a better idea when we quote.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost 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.
