New-build mastic & snagging in Gilmerton, Edinburgh
Our applicators work in Gilmerton on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Worktop and upstand sealant coming away
- Untidy sealant flagged on a snagging list
- Cracks appearing as a new home settles
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Report sealant problems to your builder during the snagging period
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
How we handle new build mastic in Gilmerton
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on plot handovers, show homes and windows & doors, and the jobs we see most are beads laid onto grit and dust from the build and messy sealant that spoils new finishes.
Offices, shops and commercial units in Scotland’s cities have floors with movement joints and thresholds that take heavy wear. In Gilmerton, we cover those floor joints as well as plot mastic for developers.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk with a short description of the job.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
My new home is still under warranty. Should I contact you?
If you are still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Do you work in Gilmerton?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Gilmerton.
How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We’ll plan around viewing times.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
Landlord and commercial work in Gilmerton
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What happens on the day
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. For a tenement in Gilmerton, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare

- Mention any parking rules near the property
- On commercial sites, let us know about site rules
How to get a quote
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
