Gladsmuir New Build Mastic
New-build sealant joints in Gladsmuir need attention? We remove the old material, prepare the joints and seal them properly.
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
- Gaps between new skirting and floors
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
New build mastic in Gladsmuir
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. If you have beads laid onto grit and dust from the build and untidy sealant flagged on a snagging list, we can put it right.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
Big or small, you get the same one-year guarantee.

Common questions in Gladsmuir
Will you come out to Gladsmuir?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is Gladsmuir in your area for new build mastic?
Yes, Gladsmuir is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Gladsmuir and the rest of East Lothian, along with the rest of our area.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. If that does not work out, we are happy to quote with our one-year guarantee.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Raise failed sealant with the developer while you’re covered
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
- Do not wait for the house to settle if water is getting through
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours in a single home for a typical job. Outside jobs in Gladsmuir 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. Indoor work goes ahead whatever the weather.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on

Advice
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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.
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. Not sure whether yours can wait? You can email us at info@mrmastic.co.uk with a few photos and we will tell you. Around Gladsmuir, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

What new build mastic looks like in Gladsmuir
Gladsmuir is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Around Gladsmuir, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Longniddry station, the sealant around baths, showers and frames is worth checking in the first year or two.
