About our new build mastic in Achnacroish
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. Common call-outs are for sealant that never bonded to the surface and skirting joints opening in the first winter, across kitchens, show homes and bathrooms & en suites.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
You get a one-year guarantee, the same in Achnacroish as everywhere else we work.

New homes and floors in Achnacroish
Achnacroish is within about 2 miles 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.
In and around Achnacroish, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. Whether the job is in Achnacroish itself or nearby, the right material for each joint matters as much as a neat finish.

How the job changes by surface
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
How we quote for new build mastic
You’ll get a clear quote before any work starts. It’s based on:
- Any working-time requirements on site
- The type of sealant required
- How much there is to do
- How many areas need sealing
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
What to tell us when you ask for a quote:
- Whether it’s a home or a business
- Where the job is, and your postcode
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.
Surfaces we seal

- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Advice
Aftercare tips
So the new joints stay in good condition:
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
- Check bath and shower seals every few months as the house settles
- Act quickly if a seal starts to leak
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
Leave it or put it right?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Achnacroish, water from a failed joint in an older stone home can soak into timber and plaster.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What you get with us
- Domestic, commercial and hotel work
- Quality sealants from Arbo and Everbuild
- We leave the area clean and tidy
- Sealant colour chosen to suit

Your questions about new build mastic in Achnacroish
Do you cover smaller places like Achnacroish?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Achnacroish in your area for new build mastic?
Yes, Achnacroish is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
Can I add another job to the visit?
Yes. Just list everything you need.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Where are you based?
We work from Crawley. Our applicators cover Achnacroish.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved for a clear quote.
