DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the 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.
New build mastic in Carlton Hill
Across Carlton Hill, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. If you’re dealing with leaking shower tray seals in a new home and second-fix sealing on new plots, we can help.
In and around Carlton Hill, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

New build mastic around Carlton Hill
Carlton Hill is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Brighton station, it’s worth checking the sealant early, while snags are still fresh. Around Carlton Hill, as everywhere, new build mastic is only as good as the preparation behind it.

Landlords, agents and businesses in Carlton Hill
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Use the extractor fan every time you shower
- Do not seal over failed sealant yourself
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What affects the quote in Carlton Hill
Jobs vary more than people expect. The main factors:
- The old material and how stubborn it is
- The size of the job
- How easy the joints are to reach
- Mould in or behind the old joints
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The type of property
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- Where the property is
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or drop us an email.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. For a job in Carlton Hill, 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 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.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Keep children and pets away from the work area

Kitchens
