About our new build mastic in Sinclairston
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on bathrooms & en suites, plot handovers and show homes, and common reasons people get in touch are sealant applied over dusty or wet surfaces and gaps behind new kitchen upstands.
For a place like Sinclairston, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
You get a one-year guarantee, the same in Sinclairston as everywhere else we work.

Joints and finishes in Sinclairston homes
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles. Sinclairston is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
Whether the job is in Sinclairston itself or nearby, the right material for each joint matters as much as a neat finish.

What we do, step by step
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Your questions about new build mastic in Sinclairston
Is new build mastic in Sinclairston guaranteed?
All our work, in Sinclairston and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you do new build mastic in Sinclairston?
Yes. We work across all of Scotland, and Sinclairston is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
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.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Check bath and shower seals every few months as the house settles
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with straight away
- Wait for the cure time before using a resealed shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Common problems we fix in Sinclairston
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Common reasons people contact us include:
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Cracks appearing as a new home settles
In and around Sinclairston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
