New build mastic in Grantshouse, done properly
We work in new homes and on new-build sites across Grantshouse. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on skirting & floors, windows & doors and plot handovers, and common reasons people get in touch are leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall.
For a place like Grantshouse, 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 are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Signs you need new build mastic in Grantshouse
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Look out for these signs:
- Cracked caulk along new skirting
- Second-fix sealing on new plots
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
If you’ve bought a new home near Reston station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic around Grantshouse

When it isn’t the sealant

- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber

Other services in Grantshouse
Different surfaces, different methods
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. 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.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
How to get a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
Related advice
Why it’s worth doing now in Grantshouse
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why Grantshouse customers choose us

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day to cure enough for use.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
Your questions about new build mastic in Grantshouse
Can you help a landlord with a rental near Reston station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Do you cover smaller places like Grantshouse?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish and agree it with you.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
How long does the job take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
