New build mastic in Chiltington
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. If you’re dealing with cracks appearing as a new home settles and new-build shower sealant that has already split, we can help, whatever the surface.
Work in a small place like Chiltington just needs the journey and access planning, and once on site, the job is the same as anywhere.
All our work is covered by a 12-month guarantee, wherever you are in East Sussex.

Chiltington questions
Is Chiltington in your area for new build mastic?
Yes. We work across London and the South East, and Chiltington is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
I let a flat near Cooksbridge station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
How long does the job take?
A typical job takes a few hours in a single home, including preparation and clearing up. Your quote will say how long we expect yours to take.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you take on second-fix sealing for builders?
Yes. We work through plots to your schedule ready for handover. Tell us the plots and the joints involved and we’ll quote.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
- Watch for new gaps as the house dries out
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.

What affects the quote in Chiltington
We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- The type of property
- Pictures of the joints, sent by email
- The address or postcode of the job
- Any access issues, like height or stairs
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or drop us an email.
Why act early in Chiltington
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Chiltington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- Every job guaranteed for a year
- Quality sealants from Arbo and Everbuild
- Over 20 years’ experience
- Sanitary silicone with an anti-fungal additive in wet areas

What we’re called out for in Chiltington

Signs it’s time to call us include:
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
- Joints pulling apart as timber shrinks
In and around Chiltington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Somewhere as small as Chiltington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Advice
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
