New build mastic in Glencoe
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you have leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall, we can help.
Around smaller Scottish places like Glencoe, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
All our work is covered by our one-year guarantee.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
What new build mastic looks like in Glencoe
Glencoe is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For jobs in and around Glencoe, choosing the right material for each joint is as important as a tidy finish. Around Glencoe, as everywhere, new build mastic is only as good as the preparation behind it.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Settlement cracks that need a surveyor
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty

How we quote for new build mastic
Every job gets its own quote. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- The amount of work
- When we can work, for business premises
- The product the joint needs
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- The rough size of the job
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Clean sealant with mild detergent, not abrasives
- Record problems with dated pictures
- Do not wait for the house to settle if water is getting through
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Questions from Glencoe
Is new build mastic in Glencoe guaranteed?
All our work, in Glencoe and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Glencoe?
Yes, Glencoe is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What happens on the day
The work is kept neat and contained to the joints we are treating. Expect the work to take a few hours in a single home. Outdoor work around Glencoe 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.

Getting a quote
