New build mastic in Moniaive, done properly
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. Common call-outs are for sealant applied over dusty or wet surfaces and smeared, uneven beads picked up at snagging, on plot handovers, kitchens and show homes.
Work in a place like Moniaive is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Why it’s worth doing now in Moniaive
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. 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.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

What new build mastic looks like in Moniaive
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

- Worktop and upstand sealant coming away

Your questions about new build mastic in Moniaive
Is there a guarantee on new build mastic in Moniaive?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Moniaive within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we will quote. We’ll flag anything that needs another trade.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
How long will you be here?
A typical job takes a few hours for most snagging lists, longer for a run of plots. Your quote will say how long we expect yours to take.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Poor preparation at handover adds to it.
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
