New build mastic in Walkerburn
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We are often asked to deal with shower seals failing in the first year or two and sealant work across a run of new homes, across plot handovers, bathrooms & en suites and show homes.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Why act early in Walkerburn
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. 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.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Walkerburn questions
Is new build mastic in Walkerburn guaranteed?
All our work, in Walkerburn and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Walkerburn in your area for new build mastic?
Yes, Walkerburn is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Can I send you my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Are you fully insured?
Yes. We’re fully insured.
DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we are called out for in Walkerburn
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- Sealant work across a run of new homes
- Untidy sealant flagged on a snagging list
- Kitchen sealant that has pulled off the wall
- Skirting joints opening in the first winter
For jobs in and around Walkerburn, choosing the right material for each joint is as important as a tidy finish.

Different surfaces, different methods
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.

What else we do in Walkerburn
What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- 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.
How to prepare
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
