New build mastic for homes and businesses in Willows Green
We work in new homes and on new-build sites across Willows Green. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. Common call-outs are for gaps behind new kitchen upstands and sealant that never bonded to the surface, on skirting & floors, bathrooms & en suites and windows & doors.
Around Willows Green, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Whatever the size of the job, it’s backed by our one-year guarantee in Willows Green and across Essex.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Willows Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area

Willows Green: your questions answered
Is Willows Green in your area for new build mastic?
Yes. We work across London and the South East, and Willows Green is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Braintree station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Should I wait before resealing?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Do you guarantee your work?
Yes. All our work carries our 12-month guarantee.
DIY versus a professional finish
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 the joint depth matters as much as the finish.
How we quote for new build mastic
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Whether the work is at height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Photos by email, if that’s easy
- The rough size of the job
- Where the job is, and your postcode
- Whether it’s a home or a business
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Landlords, agents and businesses in Willows Green
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed so the sealant lasts.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
Why act early in Willows Green
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few pictures and we’ll give you a straight answer. Where a wall is exposed, as many are in small places like Willows Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.
What you get with us
- A choice of colours where the product allows
- Every job guaranteed for a year
- Quality sealants from Arbo and Everbuild
- 20+ years of sealant experience
