Related advice
New build mastic in Port Mholair, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. We work on show homes, bathrooms & en suites and windows & doors, and common reasons people get in touch are internal frame sealant that has split and leaking shower tray seals in a new home.
For a place like Port Mholair, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Avoid running a DIY bead over the old one
- Raise failed sealant with the developer while you are covered
- Get a leaking seal dealt with straight away
- Watch for new gaps as the house dries out
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.

Joints and finishes in Port Mholair homes
Port Mholair is within about 1 mile of 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, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Port Mholair, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What the job involves on each surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Honest limits
It helps to know what we cannot do too:
- A tray or bath that is not properly supported, until it’s fixed
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.

Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.

Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
When to call us in Port Mholair
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
If you can see any of these, it’s time to have the joints looked at:
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
For jobs in and around Port Mholair, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- What preparation is included
- Which colour the sealant will be
- When the joint can take water or movement
- Who turns up on the day
