New-build mastic & snagging in East Dean, West Sussex
Problem with your new-build sealant joints in East Dean? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
New build mastic for homes and businesses in East Dean
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. Common call-outs are for leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall, across plot handovers, skirting & floors and windows & doors.
Work in a small place like East Dean just needs the journey and access planning, and once on site, the job is the same as anywhere.
Each job carries a 12-month guarantee, whatever its size.

What affects the cost of new build mastic
Your quote is based on your job. We take into account:
- How many areas need sealing
- The old material and how stubborn it is
- Any working-time requirements on site
- The amount of work
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- Where the property is
- What’s wrong with the joints now
- How we’d reach the joints
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work and send you a clear quote.
What the job involves on each surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Landlord and commercial work in East Dean
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Use the extractor fan every time you shower
- Record problems with dated photos
- Clean sealant with mild detergent, not abrasives
- Raise failed sealant with the developer while you are covered
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
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 normally takes a few hours in a single home, depending on the amount of work. In a small place like East Dean, access is normally the main thing to plan. 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.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Mention any tricky access

Advice
Why it’s worth doing now in East Dean
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. If you are unsure which you have, call 0345 464 0079 or email us with photos and we’ll tell you. Around East Dean, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
