Common problems we fix in Govan
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
These are the problems we’re asked about most:
- Untidy sealant flagged on a snagging list
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
- Sealant applied over dusty or wet surfaces
In and around Govan, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Whether they’re fully insured
- What the quote includes, VAT included or not
- Whether you can choose the colour
- Is the old sealant removed completely?
New build mastic in Govan
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. If you are dealing with sealant work across a run of new homes and skirting joints opening in the first winter, we can put it right, whatever the surface.
Offices, shops and commercial units in Scotland’s cities have floors with movement joints and thresholds that take heavy wear. Those joints, and plot mastic for developers, are part of the work we cover in Govan.
Whatever the size of the job, you get the same one-year guarantee.

What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In a tenement flat in Govan, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

Govan: your questions answered
What guarantee comes with new build mastic in Govan?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you help a landlord with a rental near Partick station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
How long does the job take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll tell you how long to expect.
How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a tenement in Govan, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

What new build mastic looks like in Govan
The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Partick station, the sealant around baths, showers and frames is worth checking in the first year or two.

What affects the quote in Govan
You will get a clear quote before we start. It takes into account:
- Working hours on commercial sites
- The product the joint needs
- The old material and how stubborn it is
- Whether the work is at height
No two jobs are quite the same, 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.
Helping us quote
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
We quote each job on its own, so the first step is telling us about yours. Simply email us at info@mrmastic.co.uk and describe the job and send photos if you have them.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Movement caused by a poorly fitted tray or bath
- Broken tiles or a split tray
- Plumbing faults behind the sealant
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
