What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can drop us a line at info@mrmastic.co.uk with a few photos and we’ll give you a straight answer. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

New build mastic in Coig Peighinnean, done properly
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 skirting joints opening in the first winter and sealant applied over dusty or wet surfaces, we can help, whatever the surface.
For a place like Coig Peighinnean, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
All of our work is guaranteed for twelve months.

What affects the cost of new build mastic
There’s no set price list. What we look at:
- Any working-time requirements on site
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
What we need to know
When you call or email, it’s useful to know:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- The type of property
- How many joints, rooms or windows are involved
If you’re in Coig Peighinnean and need new build mastic, drop us a line at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Broken tiles or a split tray
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.

What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. 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. Tell us how to find the property and how to reach the work.
- 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.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Common questions in Coig Peighinnean
What guarantee comes with new build mastic in Coig Peighinnean?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Will you come out to Coig Peighinnean?
Yes. Coig Peighinnean is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Who should fix failed sealant in a new build?
Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they will not put it right, we’ll cut it out and reseal it.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
How long does new build mastic take?
A typical job takes a few hours in a single home. Your quote will say how long we expect yours to take.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
What we are called out for in Coig Peighinnean
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:
- Leaking shower tray seals in a new home
- Cracks appearing as a new home settles
- Second-fix sealing on new plots
- Messy sealant that spoils new finishes
Whether the job is in Coig Peighinnean itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- Who does the work, and how experienced they are
- How the colour is chosen
- What the cure time is
- Whether the sealant suits the joint
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Follow the cure time we give you
- Get a leaking seal dealt with straight away
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.

Coig Peighinnean 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. Coig Peighinnean is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
