What the job involves on each surface

Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
New build mastic for homes and businesses in Ruislip
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. Common call-outs are for smeared, uneven beads picked up at snagging and joints pulling apart as timber shrinks, across show homes, skirting & floors and kitchens.
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.
There’s a 12-month guarantee on every job, whatever its size.

What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Structural cracks in walls or ceilings
- Your warranty claim itself, which is between you and the builder
- Broken tiles or a split tray
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

How it works
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours in a single home. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

New build mastic around Ruislip
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.
If you’ve bought a new home near West Ruislip station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Where do you work from?

Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
How long does new build mastic take?
Most jobs take anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
Do you need new build mastic in Ruislip?
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Look out for these signs:

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use the extractor fan every time you shower
- Keep water off fresh sealant until it has cured
- Watch for new gaps as the house dries out
- Act quickly if a seal starts to leak
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
