Westmarsh: your questions answered
Can you help a landlord with a rental near Minster station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Westmarsh?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Westmarsh and the rest of Kent.
How long does new build mastic take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. We will confirm how long when we quote.
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 flag anything that needs another trade.
Why deal with it now?
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. Older cottages and farmhouses around Westmarsh can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Settlement cracks that need a surveyor
- A tray or bath that isn’t properly supported, until it’s fixed
- Broken tiles or a split tray
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Raise failed sealant with the developer while you are covered
- Keep water off fresh sealant until it has cured
- Don’t wait for the house to settle if water is getting through
- Photograph failed sealant before it’s redone
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
