New build mastic in Perry Vale
We work in new homes and on new-build sites across Perry Vale. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you are dealing with smeared, uneven beads picked up at snagging and cracked sealant around new window and door frames, we can help, whatever the surface.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Perry Vale as anywhere.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Perry Vale: your questions answered
Do you work for landlords with property near Forest Hill station?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover Perry Vale for new build mastic?
Yes, Perry Vale is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
What colour sealant will you use?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room and agree it with you.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before we start.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Different surfaces, different methods
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Quotes for new build mastic in Perry Vale
The price is agreed before any work begins. It’s based on:
- Whether old sealant or filler has to be cut out
- The size of the job
- Whether the work is at height
- Whether there’s mould to deal with
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed

- Leaking fittings rather than failed sealant
- Damaged fittings that need replacing
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
Where we work in Perry Vale
- Kitchens
- Plot handovers
- Windows & doors
- Show homes
- Bathrooms & en suites
- Skirting & floors
Why deal with it now?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- 12-month guarantee on every job
- Neat joints and a tidy finish
- More than 20 years in sealant work
- We agree the colour with you first
Joints and finishes in Perry Vale homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Keeping the joints in good condition
So the new joints stay in good condition:
- Keep water off fresh sealant until it has cured
- Keep pictures and emails about snagging items
- Check bath and shower seals every few months as the house settles
- Wipe joints with warm soapy water
Don’t stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
