Boleside New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes in Boleside, with a one-year guarantee on every job. Ask us for a quote.
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Boleside, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- Fully insured
- A 12-month guarantee on all work
- Sealant colour chosen to suit
- Any old sealant cut out fully, not covered over

How we handle new build mastic in Boleside
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. If you’re dealing with joints pulling apart as timber shrinks and second-fix sealing on new plots, we can help.
For a place like Boleside, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
There’s a 12-month guarantee on every job, whatever its size.

Your questions about new build mastic in Boleside
Is Boleside in your area for new build mastic?
Yes. Our work covers the whole of Scotland, and Boleside is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Is Boleside within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer, and we will tell you how long to expect.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Where do you work from?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Keeping the joints in good condition
Looking after new joints is easy:
- Avoid running a DIY bead over the old one
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Watch for new gaps as the house dries out
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Different surfaces, different methods
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Joints and finishes in Boleside homes

The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. Outside jobs in Boleside need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Advice
Common problems we fix in Boleside
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
It’s worth asking for a quote if you see:
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
If you’ve bought a new home near Galashiels station, the sealant around baths, showers and frames is worth checking in the first year or two.

When it isn’t the sealant
