New build mastic in Bullsmoor: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
If you’ve bought a new home near Turkey Street station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic in Bullsmoor, done properly
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 have leaking shower tray seals in a new home and plot mastic for developers ahead of handover, we can put it right. Whether you’re looking for a mastic man, a sealant applicator or a sealant company in Bullsmoor, that’s what we do.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
You are covered for a year from the day we finish. If anything is not right with it, call 07833 053749 or drop us an email.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home, and the area is left clean. In Bullsmoor, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

Surface by surface
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
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep water off fresh sealant until it has cured
- Don’t wait for the house to settle if water is getting through
- Do not seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
How we quote for new build mastic
Every job gets its own quote. This is what makes a difference:
- Any working-time requirements on site
- The number and length of the joints
- Whether the work is at height
- The number of rooms or windows
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- Roughly how big the job is
- How we’d reach the joints
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

What else we do in Bullsmoor
Why deal with it now?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
