About our new build mastic in Belhaven
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, windows & doors and plot handovers, and common reasons people get in touch are kitchen sealant that has pulled off the wall and sealant that never bonded to the surface.
For a place like Belhaven, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What new build mastic looks like in Belhaven
Belhaven 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 Dunbar station, the sealant around baths, showers and frames is worth checking in the first year or two.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

When you call or email, it’s useful to know:
- The problem you’ve noticed

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
Ask for a quote
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Don’t seal over failed sealant yourself
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
When to call us in Belhaven
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Look out for these signs:
- Frame joints opening as the plaster dries
- Kitchen sealant that has pulled off the wall
- New-build shower sealant that has already split
- Cracked caulk along new skirting
Around Belhaven, as everywhere, new build mastic is only as good as the preparation behind it.

How long does new build mastic take?
That depends on the amount of work, but most jobs take a few hours in a single home. We’ll give you a better idea when we quote.
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. In an older home around Belhaven, damp from a failed joint can get into timber and plaster.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
