About our new build mastic in Shoreham
We work in new homes and on new-build sites across Shoreham. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you’re dealing with beads laid onto grit and dust from the build and sealant work across a run of new homes, we can help.
Somewhere as small as Shoreham, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours in a single home, including the tidy-up. For a village or hamlet like Shoreham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What we cannot put right
A few problems are outside what sealant work can do:
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
- Deciding who is responsible under a builder’s warranty
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

How the job changes by surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Shoreham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.

How we quote for new build mastic
Your quote is based on your job. We take into account:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- Which sealant suits the joint
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- Photos by email, if that is easy
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or send us an email.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep photos and emails about snagging items
- Get a leaking seal dealt with straight away
- Watch for new gaps as the house dries out
- Don’t seal over failed sealant yourself
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
