How we handle new build mastic in Ruislip Gardens
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. If you are dealing with shower seals failing in the first year or two and beads laid onto grit and dust from the build, 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.
Our work is backed for twelve months, in Ruislip Gardens and everywhere else we cover.

Ruislip Gardens questions
Can you do new build mastic in Ruislip Gardens?
Yes, Ruislip Gardens is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Can parking be tricky for a visit in Ruislip Gardens?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
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.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
What information do you need?
A short description and the location. We’ll ask anything else we need to know.
Is there any odour?
Possibly a little. It fades as the sealant cures.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
New build mastic in Ruislip Gardens: local notes
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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Ruislip Gardens can be tricky for parking: let us know about parking bays, permits or a driveway.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, 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.

Why deal with it now?
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Experience in homes, commercial sites and hotels
- Anti-fungal sanitary silicone in wet areas
- Full insurance on every job
- Arbo and Everbuild products

When to call us in Ruislip Gardens
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The problems people usually mention when they call are:
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
- Smeared, uneven beads picked up at snagging
- Cracked sealant around new window and door frames
If you’ve bought a new home near South Ruislip station, the sealant around baths, showers and frames is worth checking in the first year or two.

How it works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes a few hours in a single home. In a London area like Ruislip Gardens, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
