New-build mastic & snagging in Charleston, Dundee
Problem with your new-build sealant joints in Charleston? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Sealant that never bonded to the surface
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
New build mastic in Charleston
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. If you have sealant applied over dusty or wet surfaces and sealant work across a run of new homes, we can help.
New flats and houses are still being built in and around Scotland’s cities, and new-home owners often find sealant snags in the first year or two, in Charleston as anywhere.
Whatever the size of the job, you get the same 12-month guarantee in Charleston and across Dundee.

New build mastic around Charleston
Charleston is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, 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 Charleston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Charleston is about 2 miles west of Dundee, in Dundee. Charleston gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Our Dundee coverage runs to 50 places, and Charleston is one of them.

If you are just outside Charleston, we cover Menzieshill (1 mile south), Dryburgh (1 mile north-east), Ninewells (1 mile south), Gowrie Park (1 mile south-west) and Camperdown (1 mile north).

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

What we’re called out for in Charleston
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
People usually contact us after spotting something like this:
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
- Leaking shower tray seals in a new home
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Invergowrie station, the sealant around baths, showers and frames is worth checking in the first year or two.

Leave it or put it right?
The builder is normally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

FAQs for Charleston
Can you do new build mastic in Charleston?
Yes. Our work covers the whole of Scotland, and Charleston is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Do you work for landlords with property near Invergowrie station?
Yes, we work for letting agents and landlords. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with photos if you can. We will flag anything that needs another trade.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope and we’ll quote.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- The number and length of the joints
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

- The rough size of the job
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Any access issues, like height or stairs

What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. Parking in city streets around Charleston can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- 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.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Keep children and pets away from the work area
