New build mastic for homes and businesses in Westhampnett
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. Typical jobs include internal frame sealant that has split and beads laid onto grit and dust from the build, across show homes, plot handovers and skirting & floors.
In a village or hamlet like Westhampnett, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
There’s a 12-month guarantee on every job, large or small.

Westhampnett questions
Is Westhampnett in your area for new build mastic?
Yes, Westhampnett is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Will you come out to Westhampnett?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule. Get in touch with the number of plots and the scope and we will quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with right away
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
How it works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a small place like Westhampnett, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- 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
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Clear the area around the work

Advice
When it is not the sealant
It helps to know what we can’t do:

- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber

Do you need new build mastic in Westhampnett?
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Keep an eye out for these signs:
- Gaps behind new kitchen upstands
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
- Messy sealant that spoils new finishes
If you’ve bought a new home near Chichester station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include

New homes and floors in Westhampnett
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
