What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. In Soho, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- 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.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
Getting a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Advice
New build mastic in Soho, done properly
Across Soho, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you are dealing with joints pulling apart as timber shrinks and gaps between new skirting and floors, we can help.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Landlord and commercial work in Soho
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
New homes and floors in Soho
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. 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.
Soho is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Soho is about 1 mile east of City of Westminster, in Greater London. Homes, rented property, offices and hotels in Soho can book us for new build mastic, old or new, large or small. The work is guaranteed for a year. Soho is one of 764 towns and villages in Greater London where we work.

What’s near Soho

You will also find LITE Regal International School (0.6 miles west) and London Library (0.5 miles south-west). Soho has its own railway station: Tottenham Court Road station.

Why it’s worth doing now in Soho
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, phone 0345 464 0079 or email us with photos and we’ll give you a straight answer. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why Soho customers choose us
- Anti-fungal sanitary silicone in wet areas
- Any old sealant cut out fully, not covered over
- You choose the colour before work begins
- Trusted Arbo and Everbuild sealants

When to call us in Soho
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Common reasons people contact us are:
- Smeared, uneven beads picked up at snagging
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
If you’ve bought a new home near Tottenham Court Road station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Who turns up on the day
- What guarantee comes with the work
- What the cure time is
- Whether the sealant suits the joint
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
FAQs for Soho
Is parking an issue for new build mastic in Soho?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Tottenham Court Road station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope for a clear quote.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Are you insured?
Yes, we’re fully insured.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. Sealant will not put right:
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
