New build mastic for homes and businesses in Armadale
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly. If you have gaps between new skirting and floors and gaps opening as the house dries out and settles, we can help, whatever the surface.
Work in a place like Armadale is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Big or small, you get the same one-year guarantee.

What else we do in Armadale
What new build mastic looks like in Armadale
Armadale is close to 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. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Mallaig station, the sealant around baths, showers and frames is worth checking in the first year or two.

What happens on the day
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work usually takes anything from a few hours to several days, depending on the number of plots. Outside jobs in Armadale need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Mention any parking rules near the property
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Advice
How the job changes by surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Signs you need new build mastic in Armadale
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Common reasons people contact us include:
- Messy sealant that spoils new finishes
- Cracked caulk along new skirting
- Plot mastic for developers ahead of handover
- Shower seals failing in the first year or two
Around Armadale, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Whether VAT is included
- What preparation is included
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
Landlord and commercial work in Armadale
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In an older home around Armadale, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why book with us
- 12-month guarantee on every job
- You choose the colour before work begins
- Trusted Arbo and Everbuild sealants
- Old sealant always removed completely

Your questions about new build mastic in Armadale
I let a flat near Mallaig station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Is Armadale in your area for new build mastic?
Yes, Armadale is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
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.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
