Signs you need new build mastic in Na Gearrannan
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
People generally contact us when they notice one of these:
- Cracks appearing as a new home settles
- Gaps between new skirting and floors
- Sealant that never bonded to the surface
- Internal frame sealant that has split
For jobs in and around Na Gearrannan, choosing the right material for each joint is as important as a tidy finish.

How we handle new build mastic in Na Gearrannan
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant usually lacks. We work on plot handovers, windows & doors and show homes, and people most often call us about sealant that never bonded to the surface and second-fix sealing on new plots.
For a place like Na Gearrannan, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
There’s a 12-month guarantee on every job, whatever its size.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Use the extractor fan every time you shower
- Don’t wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
- Put sealant faults on your snagging list early
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Around Na Gearrannan, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- How many areas need sealing

- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
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, and add photos by email if you can.

Your questions about new build mastic in Na Gearrannan
What guarantee comes with new build mastic in Na Gearrannan?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Na Gearrannan?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Is it worth resealing while the house is still settling?
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.
What do you need from me for a quote?
Let us know what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with photos if you can. We’ll flag anything that needs another trade.
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant can’t fix:
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Kitchens
- Skirting & floors
- Bathrooms & en suites
- Show homes
- Windows & doors
- Plot handovers
What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. 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.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
