- Smeared, uneven beads picked up at snagging
New build mastic in Snow Hill, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on show homes, bathrooms & en suites and skirting & floors, and common reasons people get in touch are internal frame sealant that has split and second-fix sealing on new plots.
Around Snow Hill, 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.
Big or small, you get the same one-year guarantee in Snow Hill and across West Sussex.

Do you need new build mastic in Snow Hill?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
For new homes near East Grinstead station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- How much experience the applicator has
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- How the surfaces are prepared before sealing
How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours in a single home, including the tidy-up. Somewhere like Snow Hill needs a little journey planning: let us know about lanes, gates and parking. 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.
- 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.
Before we arrive
- Clear items away from the joints we’re working on
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- The number of rooms or windows
- The old material and how stubborn it is
- The amount of work
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before any work starts.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- A few pictures by email, if you can
- Roughly how big the job is
- Access, such as stairs, a lift or height
- The type of property
To get a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before any work starts.
For landlords and businesses
We also work for property managers and facilities teams in Snow Hill and across West Sussex. We can quote a run of properties together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

New homes and floors in Snow Hill
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Snow Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

How to look after the new joints
Aftercare is simple:
- Avoid scourers and strong chemicals on sealant
- Avoid running a DIY bead over the old one
- Get a leaking seal dealt with right away
- Raise failed sealant with the developer while you are covered
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
