How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. Somewhere like Botley 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.

How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.

Landlords, agents and businesses in Botley
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Botley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

- Rated 4.9 stars on Google
- Neat joints and a tidy finish
- Sealant colour chosen to suit
- A choice of colours where the product allows
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Do you need new build mastic in Botley?
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Any of these means the joints need attention:
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
Around Botley, as everywhere, new build mastic is only as good as the preparation behind it.

Your questions about new build mastic in Botley
Can you help a landlord with a rental near Amersham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Can you do new build mastic in Botley?
Yes, Botley is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
When is the sealant fully cured?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us and tell us what needs doing and where.
Do you have insurance?
Yes. Full insurance covers our work.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.
Aftercare tips
To keep the joints looking good and working properly:
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Keep photos and emails about snagging items
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
New homes and floors in Botley
Rainfall in the South East is lower than in much 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 Amersham station, it’s worth checking the sealant early, while snags are still fresh.
