Questions from Shortlands
Is parking an issue for new build mastic in Shortlands?
Parking in Shortlands, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Shortlands station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we will ask.
How much does new build mastic cost in Shortlands?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. If that doesn’t work out, we’re happy to quote.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Do you come to Shortlands?
Yes, we do. Shortlands is part of the area we cover, and the service is the same as everywhere else.
About our new build mastic in Shortlands
Across Shortlands, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on show homes, skirting & floors and windows & doors, and people most often call us about sealant applied over dusty or wet surfaces and messy sealant that spoils new finishes.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Common problems we fix in Shortlands
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
These are the problems we are asked about most:
- Worktop and upstand sealant coming away
- Plot mastic for developers ahead of handover
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
Shortlands is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

New build mastic around Shortlands
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
For new homes near Shortlands station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.
Leave it or put it right?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Shortlands, the repair is bigger than a sealant job.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep water off fresh sealant until it has cured
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home from start to finish. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Shortlands. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
