Signs you need new build mastic in Rout's Green
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Most people get in touch when they notice one of these:
- New-build shower sealant that has already split
- Kitchen sealant that has pulled off the wall
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Saunderton station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic for homes and businesses in Rout's Green
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. If you have cracked sealant around new window and door frames and leaking shower tray seals in a new home, we can help, on skirting & floors, bathrooms & en suites and windows & doors alike.
For a small place like Rout's Green, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition
Aftercare is simple:
- Record problems with dated pictures
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
- Avoid running a DIY bead over the old one
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day to cure enough for use.
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.
Rout's Green: your questions answered
Can you do new build mastic in Rout's Green?
Yes. Our work covers London and the South East, and Rout's Green is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Saunderton station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why has my new-build shower seal failed already?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long does the job take?
Most jobs take a few hours in a single home. Your quote will say how long we expect yours to take.

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. In a small place like Rout's Green, access is usually the main thing to plan.

- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- 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.
How to prepare
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
