About our new build mastic in Putney Vale
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. If you are dealing with new-build shower sealant that has already split and untidy sealant flagged on a snagging list, we can help.
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 failed shower seals, open skirting joints and gaps at thresholds are typical.
All of our work is guaranteed for twelve months.

What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. In a London area like Putney Vale, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Honest limits
To be straight with you, some problems need a different trade:
- A tray or bath that is not properly supported, until it’s fixed
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

FAQs for Putney Vale
Do you work for landlords with property near Raynes Park station?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Is parking an issue for new build mastic in Putney Vale?
Parking in Putney Vale, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for property managers and facilities teams in Putney Vale and across Greater London. We can quote a run of properties together, and we are fully insured for the work.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
