About our new build mastic in Penton Hook
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Typical jobs include shower seals failing in the first year or two and skirting joints opening in the first winter, on show homes, skirting & floors and plot handovers.
For a small place like Penton Hook, the journey and access are planned in advance, and the work itself is the same as on any site.
All of our work is guaranteed for twelve months, in Penton Hook and everywhere else we cover.

When to call us in Penton Hook
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
People normally contact us when they notice something like this:
- Smeared, uneven beads picked up at snagging
- Sealant applied over dusty or wet surfaces
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
Around Penton Hook, as everywhere, new build mastic is only as good as the preparation behind it.

Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Older cottages and farmhouses around Penton Hook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. In a small place like Penton Hook, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before work begins.
- 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.
Before we arrive
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

What else we do in Penton Hook
Penton Hook: your questions answered
Is Penton Hook 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.
Is Penton Hook in your area for new build mastic?
Yes. We work across London and the South East, and Penton Hook is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints.
Who should fix failed sealant in a new build?
Start with the builder if you are in the snagging or warranty period. Once that’s done, or if they will not put it right, we’ll cut it out and reseal it.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Looking after it afterwards
To keep the joints looking good and working properly:
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
