The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. In a London area like Hooley, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Advice
New build mastic for homes and businesses in Hooley
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on skirting & floors, bathrooms & en suites and windows & doors, and common reasons people get in touch are untidy sealant flagged on a snagging list and cracked sealant around new window and door frames.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Whatever the size of the job, you get the same one-year guarantee.

What we’re called out for in Hooley
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracked sealant shows up.
Look out for any of the following:
- Untidy sealant flagged on a snagging list
- Internal frame sealant that has split
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
Hooley is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Common questions in Hooley
Can you do new build mastic in Hooley?
Yes. Our work covers London and the South East, and Hooley is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Is parking a problem for a job in Hooley?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.
How we quote for new build mastic
We don’t publish a price list, because jobs vary so much. What we look at:
- When we can work, for business premises
- The type of sealant required
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Asking for a quote
To make quoting easier, let us know:
- Whether it’s a home or a business
- A few pictures by email, if you can
- The address or postcode of the job
- If someone has resealed it before
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
New homes and floors in Hooley
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
If you’ve bought a new home near Chipstead station, the sealant around baths, showers and frames is worth checking in the first year or two.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
