About our new build mastic in South Weald
Across South Weald, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. We are often asked to deal with sealant that never bonded to the surface and second-fix sealing on new plots, on kitchens, show homes and bathrooms & en suites.
In a village or hamlet like South Weald, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Whatever the size of the job, you get the same 12-month guarantee.

Questions from South Weald
Can you do new build mastic in South Weald?
Yes, South Weald is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Brentwood station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
How much does new build mastic cost in South Weald?
Size, access and the old material all affect the cost. Ask us for a quote.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours in a single home, depending on the amount of work. In a small place like South Weald, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely 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.
- Each bead is tooled and the cure times explained.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive

Advice
Aftercare tips
So the new joints stay in good condition:
- Do not seal over failed sealant yourself
- Get a leaking seal dealt with straight away
- Ventilate bathrooms well, especially in the first year
- Photograph failed sealant before it’s redone
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
What new build mastic looks like in South Weald
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Around South Weald, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
