How we handle new build mastic in Ruxley
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. If you have untidy sealant flagged on a snagging list and worktop and upstand sealant coming away, we can put it right, on show homes, skirting & floors and kitchens alike.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
Our work is backed for twelve months, in Ruxley and everywhere else we cover.

Ruxley: your questions answered
Is Ruxley in your area for new build mastic?
Yes. Our work covers London and the South East, and Ruxley is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Albany Park station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
How long should I leave it?
It depends on the product. Before we leave, we’ll tell you the cure time.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, wherever you are.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Can you work from my snagging list?
Yes. Send the list and a few photos of the sealant items. We’ll flag anything that needs another trade.
What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
The process
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a job in Ruxley, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
Advice
When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Leaks from pipes, valves or wastes, which need a plumber
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Resist patching a failed seal with a tube from the DIY shop
- Ventilate bathrooms well, especially in the first year
- Record problems with dated photos
- Wipe joints with warm soapy water
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
New build mastic around Ruxley
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. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Ruxley can be tricky for parking: let us know about parking bays, permits or a driveway. For new homes near Albany Park station, it’s worth checking the sealant early, while snags are still fresh.
