How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a small place like West Grinstead, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

How we handle new build mastic in West Grinstead
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 isn’t put right, get in touch with us. If you are dealing with shower seals failing in the first year or two and cracked sealant around new window and door frames, we can help, on windows & doors, kitchens and bathrooms & en suites alike.
Somewhere as small as West Grinstead, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Every job is covered by a 12-month guarantee.

What else we do in West Grinstead
Different surfaces, different methods
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Your questions about new build mastic in West Grinstead
What guarantee comes with new build mastic in West Grinstead?
All our work, in West Grinstead and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is West Grinstead within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Landlord and commercial work in West Grinstead
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Signs you need new build mastic in West Grinstead
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
If you can see any of these, it’s time to have the joints looked at:
- Shower seals failing in the first year or two
- Gaps between new skirting and floors
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
Around West Grinstead, as everywhere, new build mastic is only as good as the preparation behind it.

Why act early in West Grinstead
A hairline gap at a skirting can wait, but a leaking seal cannot. If you are unsure which you have, ring 0345 464 0079 or send us an email with pictures. In a small place like West Grinstead, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Do not wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Avoid running a DIY bead over the old one
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
