New build mastic for homes and businesses in Hellingly
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. If you’re dealing with cracks appearing as a new home settles and gaps between new skirting and floors, we can put it right.
Where new homes go up in smaller places like Hellingly, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.

Why deal with it now?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a smaller place like Hellingly, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Common problems we fix in Hellingly
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
If you can see any of these, it’s time to have the joints looked at:
- Cracks appearing as a new home settles
- Internal frame sealant that has split
- Sealant that never bonded to the surface
- Sealant work across a run of new homes
For new homes near Polegate station, it’s worth checking the sealant early, while snags are still fresh.

FAQs for Hellingly
Is Hellingly in your area for new build mastic?
Yes. Our work covers London and the South East, and Hellingly is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is Hellingly within the area you cover?
Yes. Hellingly is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
Do you take on second-fix sealing for builders?
Yes. We work through plots to your schedule ready for handover. Get in touch with the number of plots and the scope for a clear quote.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Why has my new-build shower seal failed already?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
What affects the quote in Hellingly
Your quote is based on your job. We take into account:
- The type of sealant required
- How many rooms, windows or areas are involved
- Any mould that needs treating
- When we can work, for business premises
Instead of a standard rate, 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.
Helping us quote
When you call or email, these details help:
- Photos by email, if that is easy
- Any access issues, like height or stairs
- Whether it’s a home or a business
- Where the property is
If you’re in Hellingly and need new build mastic, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before we start.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
When something else is needed
Before you book, it’s worth knowing the limits:
- Broken tiles or a split tray
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal

The process
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job normally takes anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. A visit to Hellingly is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- 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
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
