Your questions about new build mastic in Kirknewton

I let a flat near Kirknewton station. Can you help?

Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.

Do you cover Kirknewton for new build mastic?

Yes. We work across all of Scotland, and Kirknewton is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.

When is the best time to reseal in a new build?

Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.

Can I send you my snagging list?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

Is it normal for sealant to crack in a new home?

Cracking in the first couple of years is common, because the house is drying and settling. Poor preparation at handover adds to it.

What colour sealant will you use?

We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.

Are you insured?

Yes, we are fully insured for every job we do.

New build mastic in Kirknewton, done properly

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. We are often asked to deal with cracked sealant around new window and door frames and messy sealant that spoils new finishes, on skirting & floors, show homes and bathrooms & en suites.

For a place like Kirknewton, the journey and access are planned in advance. 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 covered after we’ve gone.

New homes and floors in Kirknewton

Leave it or put it right?

It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. 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.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

For landlords and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.

What the job involves on each surface

Show homes

We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.

Plot handovers

Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.

Looking after it afterwards

Joint life depends on how it’s used and looked after. Here’s what we suggest:

Wait for the cure time before using a resealed shower
Watch for new gaps as the house dries out
Resist patching a failed seal with a tube from the DIY shop
Do not wait for the house to settle if water is getting through

Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.

Signs you need new build mastic in Kirknewton

Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.

The most common problems we see are:

Joints pulling apart as timber shrinks
Cracked sealant around new window and door frames
Skirting joints opening in the first winter
Shower seals failing in the first year or two

In and around Kirknewton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
