Common problems we fix in Chobham
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.
The problems people usually mention when they call include:
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
Around Chobham, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Chobham
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We work on skirting & floors, show homes and windows & doors, and the jobs we see most are gaps opening as the house dries out and settles and gaps between new skirting and floors.
If you’ve bought a new home in or near Chobham, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Big or small, you get the same 12-month guarantee.

New build mastic around Chobham
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.
For new homes near Longcross station, it’s worth checking the sealant early, while snags are still fresh.

Why it’s worth doing now in Chobham
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Homes in smaller places like Chobham can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why Chobham clients choose us
- A 12-month guarantee on all work

How we quote for new build mastic
For a quick quote, just ask. What matters most is:
- Whether there’s mould to deal with
- The size of the job
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.
Asking for a quote
When you call or email, it’s useful to know:
- A few pictures by email, if you can
- The rough size of the job
- Any access issues, like height or stairs
- Whether it’s a home or a business
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Act quickly if a seal starts to leak
- Record problems with dated photos
- Raise failed sealant with the developer while you are covered
- Follow the cure time we give you
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
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.
When it isn’t the sealant
To be straight with you, there are a few things sealant will not fix:
- Damaged fittings that need replacing
- Disputes or warranty claims with your builder
- A tray or bath that is not properly supported, until it’s fixed
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home and we leave things clean and tidy. For a job in Chobham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
