- Cracks appearing as a new home settles
- Worktop and upstand sealant coming away
- Sealant that never bonded to the surface
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few pictures and we will give you a straight answer. Where a wall is exposed, as many are in small places like North Heath, 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. Your quote takes all of that into account.
Why us?
- We agree the colour with you first
- Anti-fungal sanitary silicone in wet areas
- Over 20 years’ experience
- Full insurance on every job

New build mastic in North Heath, done properly
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We are often asked to deal with kitchen sealant that has pulled off the wall and second-fix sealing on new plots, on windows & doors, show homes and skirting & floors.
Somewhere as small as North Heath, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in North Heath
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes a few hours in a single home. For a village or hamlet like North Heath, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Tell us if parking is tricky

Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.
FAQs for North Heath
Do you work for landlords with property near Pulborough station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do you cover smaller places like North Heath?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.
Do you need new build mastic in North Heath?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
It’s worth asking for a quote if you see:
- Sealant that never bonded to the surface
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
- Gaps between new skirting and floors
For new homes near Pulborough station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Are they insured?
- Which colour the sealant will be
- What the cure time is
- How much experience the applicator has
How to look after the new joints
So the new joints stay in good condition:
- Wipe joints with warm soapy water
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- The amount of work
- Any mould that needs treating
- The old material and how stubborn it is
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
