New build mastic in New England, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Common call-outs are for new-build shower sealant that has already split and frame joints opening as the plaster dries, on skirting & floors, bathrooms & en suites and windows & doors.
Older homes in small places like New England often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, whatever its size.

Joints and finishes in New England homes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For jobs in and around New England, choosing the right material for each joint is as important as a tidy finish.
New England is in Essex. We provide new build mastic to homes and businesses in New England and nearby, as part of our work across Essex. 644 places in Essex are on our list, from the larger towns to small villages. There’s also a page for Chelmsford, roughly 22 miles from New England.

For landlords and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
How the job changes by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Do you need new build mastic in New England?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
The problems people usually mention when they call include:
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
In and around New England, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

FAQs for New England
Is New England in your area for new build mastic?
Yes, New England is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Is there a guarantee on new build mastic in New England?
All our work, in New England and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We agree the sealant items with you before work begins.
Will you just run a new bead over the existing one?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
What does new build mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Are you insured?
Yes. We’re fully insured.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- Mould in or behind the old joints
- The old material and how stubborn it is
- Any working-time requirements on site
- The type of sealant required
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- Photos by email, if that’s easy
- The type of property
To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as New England, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- 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.
Preparing for the visit
- Tell us about any water getting in
- Clear the area around the work
- Keep children and pets away from the work area
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

What sealant work cannot fix
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Don’t wait for the house to settle if water is getting through
- Put sealant faults on your snagging list early
- Follow the cure time we give you
- Open a window or run the fan after bathing
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
