New build mastic in Copshaw Holm, done properly
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have worktop and upstand sealant coming away and leaking shower tray seals in a new home, we can help, on windows & doors, show homes and plot handovers alike.
For a place like Copshaw Holm, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
Big or small, you get the same one-year guarantee in Copshaw Holm and across the Scottish Borders.

Aftercare tips
So the new joints stay in good condition:
- Record problems with dated photos
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
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.

What we do, step by step
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. In smaller Scottish places, parking is normally 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.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Advice
How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Why act early in Copshaw Holm
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Questions from Copshaw Holm
Do you cover smaller places like Copshaw Holm?
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.
What guarantee comes with new build mastic in Copshaw Holm?
All our work, in Copshaw Holm and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then drop us a line at info@mrmastic.co.uk.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. If it isn’t resolved, we can reseal it properly.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
New homes and floors in Copshaw Holm

When to call us in Copshaw Holm
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Look out for any of the following:
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
Whether the job is in Copshaw Holm itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- Who turns up on the day
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
