Your questions about new build mastic in St Lawrence Bay
Is St Lawrence Bay within the area you cover?
Yes, St Lawrence Bay is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Southminster station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before work begins.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
When something else is needed
A few problems are outside what sealant work can do:
- Cracking that points to a structural problem
- Deciding who is responsible under a builder’s warranty
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Why it’s worth doing now in St Lawrence Bay
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. In a small place like St Lawrence Bay, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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.

Different surfaces, different methods
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Show homes
We seal show-home bathrooms, kitchens and frames. Tell us when the home is open so we can plan around it.
What new build mastic looks like in St Lawrence Bay
St Lawrence Bay is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around St Lawrence Bay, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Southminster station, the sealant around baths, showers and frames is worth checking in the first year or two.

What else we do in St Lawrence Bay
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid scourers and strong chemicals on sealant
- Put sealant faults on your snagging list early
- Keep pictures and emails about snagging items
- Look at the sealant regularly in the first couple of years
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.
