New build mastic in Cobham: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Cobham & Stoke Dabernon station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic for homes and businesses in Cobham
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. Typical jobs include second-fix sealing on new plots and beads laid onto grit and dust from the build, on bathrooms & en suites, skirting & floors and windows & doors.
In smaller places like Cobham, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We stand behind the work with a 12-month guarantee.

What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Plumbing faults behind the sealant
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

- Windows & doors

- Skirting & floors
- Show homes
- Plot handovers

Your questions about new build mastic in Cobham
Do you cover smaller places like Cobham?
Yes. Cobham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do new build mastic in Cobham?
Yes. Our work covers London and the South East, and Cobham is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Should I wait before resealing?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
How long should I leave it?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Landlord and commercial work in Cobham
Letting agents and landlords in Cobham can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Different surfaces, different methods
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Aftercare tips
To keep the joints looking good and working properly:
- Use the extractor fan every time you shower
- Act quickly if a seal starts to leak
- Photograph failed sealant before it’s redone
- Put sealant faults on your snagging list early
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, phone 0345 464 0079 or send us an email with pictures and we’ll tell you. Homes in smaller places like Cobham can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most snagging lists, longer for a run of plots. For a job in Cobham, 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
How to get a quote
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand.

What we’re called out for in Cobham
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
These are the problems we’re asked about most:
- Kitchen sealant that has pulled off the wall
- Plot mastic for developers ahead of handover
- Shower seals failing in the first year or two
- Gaps between new skirting and floors
Around Cobham, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Is the old sealant removed completely?
- Who turns up on the day
- Whether they’re fully insured
- Which sealant they’ll use, and why
