New build mastic in Sgalpaigh, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. We work on plot handovers, skirting & floors and bathrooms & en suites, and people most often call us about gaps opening as the house dries out and settles and leaking shower tray seals in a new home.
Work in a place like Sgalpaigh is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Outside jobs in Sgalpaigh need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

What new build mastic looks like in Sgalpaigh
Sgalpaigh 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For jobs in and around Sgalpaigh, choosing the right material for each joint is as important as a tidy finish. Around Sgalpaigh, as everywhere, new build mastic is only as good as the preparation behind it.
Sgalpaigh (Gaelic: Scalpay) is in Na h-Eileanan Siar. For new build mastic in and around Sgalpaigh, it’s easy to get a quote: please drop us a line at info@mrmastic.co.uk. We cover Na h-Eileanan Siar from our Crawley base. Sgalpaigh is one of 87 places in Na h-Eileanan Siar where we work.
Our applicators cover all of HS4 for new build mastic and the streets around it. If you are just outside Sgalpaigh, we cover Plocrapool (3 miles south-west), Drinisiadar (3 miles west), Scadabhagh (3 miles south-west), Miabhaig (4 miles west) and Greosabhagh (4 miles south-west). Remote and island addresses need a little more planning, so tell us where you are when you ask for a quote.
Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated pictures
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Broken tiles or a split tray
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

FAQs for Sgalpaigh
Is Sgalpaigh in your area for new build mastic?
Yes. Our work covers the whole of Scotland, and Sgalpaigh is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will you come out to Sgalpaigh?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. Once that’s done, or if they will not put it right, we’ll cut it out and reseal it.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
