How we handle new build mastic in Thornton
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We are often asked to deal with shower seals failing in the first year or two and cracked sealant around new window and door frames, on kitchens, plot handovers and windows & doors.
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.
Each job carries a 12-month guarantee, whatever its size.

Thornton questions
Do you cover smaller places like Thornton?
Yes, Thornton is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Thornton for new build mastic?
Yes, Thornton is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with photos if you can and we’ll give you a quote. We’ll tell you if anything on it is not a sealant job.
What affects the quote in Thornton
We quote each job individually. These are the things that affect it:
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Mould in or behind the old joints
- How easy the joints are to reach
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The address or postcode of the job
- A few photos by email, if you can
- Whether it’s a home or a business
- The problem you’ve noticed
For a quote, email us at info@mrmastic.co.uk with the location and a short description of the problem. We’ll give you a clear price before any work starts.
Keeping the joints in good condition
Aftercare is simple:
- Record problems with dated photos
- Wait for the cure time before using a resealed shower
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
New build mastic around Thornton
Thornton is within about 3 miles of 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, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Thornton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we can’t put right
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

What we’re called out for in Thornton
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Common reasons people contact us are:
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
- Plot mastic for developers ahead of handover
- Sealant applied over dusty or wet surfaces
For new homes near Glenrothes with Thornton station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Whether you can choose the colour
- Who does the work, and how experienced they are
- Whether they’re fully insured
- How the surfaces are prepared before sealing
