Why it’s worth doing now in East Challow

If you’re unsure which you have, call 0345 464 0079 or send us an email with pictures and we will give you a straight answer. Older cottages and farmhouses around East Challow can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

About our new build mastic in East Challow
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. We work on bathrooms & en suites, plot handovers and skirting & floors, and people most often call us about untidy sealant flagged on a snagging list and sealant applied over dusty or wet surfaces.
Somewhere as small as East Challow, 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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

East Challow questions
Is there a guarantee on new build mastic in East Challow?
All our work, in East Challow and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will you come out to East Challow?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early. Rushed application on dusty surfaces makes it worse.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
How long before the joint can be used?
Cure times vary by product. Before we leave, we will tell you the cure time.
How long does the job take?
That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on the number of plots. We’ll tell you when we quote.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
New build mastic around East Challow
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

When it is not the sealant
In fairness, there are a few things sealant won’t fix:
- Disputes or warranty claims with your builder
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

What the job involves on each surface
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
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 in a single home, and the area is left clean. Somewhere like East Challow needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- 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.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

Related advice
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
- Use the extractor fan every time you shower
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
