Tweedbank New Build Mastic
Problem with your new-build sealant joints in Tweedbank? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Leaking shower tray seals in a new home
- Kitchen sealant that has pulled off the wall
- Joints pulling apart as timber shrinks
The process
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours in a single home. Outdoor work around Tweedbank depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- 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.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Clear the area around the work
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

New build mastic in Tweedbank, done properly
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. Typical jobs include frame joints opening as the plaster dries and second-fix sealing on new plots, on skirting & floors, show homes and windows & doors.
Work in a place like Tweedbank is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
You’re 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.

What affects the cost of new build mastic
Your quote is based on your job. We take into account:
- How much there is to do
- Whether the work is at height
- Working hours on commercial sites
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- How we’d reach the joints
- Any previous sealing or DIY work
- The rough size of the job
- A few photos by email, if you can
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, drop us a line at info@mrmastic.co.uk.
Tweedbank questions
I let a flat near Tweedbank station. Can you help?
Yes, we work for landlords and agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Can you do new build mastic in Tweedbank?
Yes. Our work covers the whole of Scotland, and Tweedbank is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What the job involves on each surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Landlords, agents and businesses in Tweedbank
If you manage several properties in or around Tweedbank, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Do you need new build mastic in Tweedbank?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
The most common problems we see are:
- Messy sealant that spoils new finishes
- Leaking shower tray seals in a new home
- Cracks appearing as a new home settles
- Internal frame sealant that has split
If you’ve bought a new home near Tweedbank station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- What insurance they hold
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
- Is VAT in the price?
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
