New-build mastic & snagging in Oxton, Scottish Borders
Problem with your new-build sealant joints in Oxton? We remove the old material, prepare the joints and seal them properly.
- Joints pulling apart as timber shrinks
- Gaps behind new kitchen upstands
- Messy sealant that spoils new finishes
How we handle new build mastic in Oxton
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on bathrooms & en suites, skirting & floors and kitchens, and people most often call us about untidy sealant flagged on a snagging list and frame joints opening as the plaster dries.
For a place like Oxton, 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.
All our work is covered by a 12-month guarantee, wherever you are in the Scottish Borders.

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours in a single home, depending on the amount of work. Outside jobs in Oxton need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Clear the area around the work
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

What happens if it’s left?
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. In an older home around Oxton, damp from a failed joint can get into timber and plaster.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.

What else we do in Oxton
Do you need new build mastic in Oxton?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
People normally contact us when they notice one of these:
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
- Internal frame sealant that has split
- Sealant applied over dusty or wet surfaces
For jobs in and around Oxton, choosing the right material for each joint is as important as a tidy finish.

Do you take on second-fix sealing for builders?

Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
