New build mastic in Milton, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. We work on skirting & floors, kitchens and windows & doors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and cracks appearing as a new home settles.
For a place like Milton, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
All of our work is guaranteed for twelve months, in Milton and everywhere else we cover.

How we quote for new build mastic
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The old material and how stubborn it is
- Working hours on commercial sites
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
To help us quote quickly, let us know:
- What’s wrong with the joints now
- Roughly how big the job is
- Where the property is
- Whether it has been sealed before

Milton: your questions answered
Is Milton within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is Milton in your area for new build mastic?
Yes, Milton is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with pictures if you can, and we’ll quote. We will flag anything that needs another trade.
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.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, wherever you are.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Raise failed sealant with the developer while you’re covered
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
- Don’t seal over failed sealant yourself
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.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In an older home around Milton, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. For a place like Milton, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints

What the job involves on each surface
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.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out and baths are filled before sealing.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.
