New build mastic for homes and businesses in Scarwell
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on show homes, bathrooms & en suites and plot handovers, and people most often call us about plot mastic for developers ahead of handover and gaps opening as the house dries out and settles.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
Whatever the size of the job, you get the same one-year guarantee.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Raise failed sealant with the developer while you are covered
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
FAQs for Scarwell
What guarantee comes with new build mastic in Scarwell?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover Scarwell for new build mastic?
Yes. We work across all of Scotland, and Scarwell is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
My new home is still under warranty. Should I contact you?
Start with the builder if you’re in the snagging or warranty period. If it is not resolved, we can reseal it properly.
Do you have insurance?
Yes, we’re fully insured.
What we’re called out for in Scarwell
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
The most common problems we see are:
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
- Sealant that never bonded to the surface
In and around Scarwell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Who turns up on the day
- Whether they’re fully insured
- What the cure time is
- Is the old sealant removed completely?
What affects the cost of new build mastic
There’s no set price list. The quote depends on:
- Mould in or behind the old joints
- The size of the job
- Any working-time requirements on site
- How many rooms, windows or areas are involved
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- A few photos by email, if you can
- Whether it’s a home or a business
- Where the job is, and your postcode
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, drop us a line at info@mrmastic.co.uk.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- 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
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
How to get a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Advice
Different surfaces, different methods
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
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.

Why act early in Scarwell
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Scarwell, water from a failed joint in an older stone home can soak 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. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why us?
- A 12-month guarantee on all work
- Any old sealant cut out fully, not covered over

New homes and floors in Scarwell
Scarwell is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
