New Build Mastic in Sompting
Our applicators work in Sompting on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
- New-build shower sealant that has already split
How it works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work starts. The work normally takes a few hours in a single home. For a job in Sompting, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
How to get a quote

How we handle new build mastic in Sompting
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first. We work on windows & doors, show homes and plot handovers, and the jobs we see most are skirting joints opening in the first winter and beads laid onto grit and dust from the build.
In smaller places like Sompting, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Plumbing faults behind the sealant
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

New homes and floors in Sompting
Sompting is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Lancing station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Sompting, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
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.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Record problems with dated photos
- Wipe joints with warm soapy water
- Do not wait for the house to settle if water is getting through
- Put sealant faults on your snagging list early
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
