Our applicators work in Balfour on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.

New build mastic for homes and businesses in Balfour
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We’re often asked to deal with cracked caulk along new skirting and worktop and upstand sealant coming away, on bathrooms & en suites, plot handovers and skirting & floors.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
All our work comes with our one-year guarantee.

Aftercare tips
A little care helps the new joints last. Our advice:
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
- Wipe joints with warm soapy water
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
What we do, step by step
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Outdoor work around Balfour depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Advice
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
New homes and floors in Balfour
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.

What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Combining jobs into one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Signs you need new build mastic in Balfour
Sealant applied onto damp surfaces doesn’t bond well. Site programmes do not always leave time for joints to dry.
Any of these means the joints need attention:
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
For jobs in and around Balfour, choosing the right material for each joint is as important as a tidy finish.

Balfour: your questions answered
Is there a guarantee on new build mastic in Balfour?
All our work, in Balfour and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you do new build mastic in Balfour?
Yes, Balfour is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Why does sealant fail so quickly in new builds?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. If it isn’t resolved, we’ll cut it out and reseal it.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
