New build mastic for homes and businesses in Westwoodhill
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We work on kitchens, plot handovers and show homes, and people most often call us about cracked sealant around new window and door frames and gaps opening as the house dries out and settles.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Big or small, it’s backed by our one-year guarantee.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What the job involves on each surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours in a single home. Outside jobs in Westwoodhill need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions

Advice
How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- The type of sealant required
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
When you call or email, it’s useful to know:
- If someone has resealed it before
- Photos by email, if that’s easy
- The problem you’ve noticed
- The rough size of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, drop us a line at info@mrmastic.co.uk.
When to call us in Westwoodhill
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry first.
The most common problems we see are:
- Frame joints opening as the plaster dries
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Untidy sealant flagged on a snagging list
Around Westwoodhill, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- Who does the work, and how experienced they are
- How hidden problems are handled
- When the joint can take water or movement
- Which sealant they’ll use, and why
Westwoodhill questions

Will you come out to Westwoodhill?
Yes. Westwoodhill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. Once that is done, or if they will not put it right, we can reseal it properly.
Joints and finishes in Westwoodhill homes
Westwoodhill is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Hairmyres station, the sealant around baths, showers and frames is worth checking in the first year or two.
