Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
What happens if it’s left?
Before an inspection, audit or busy season, sealant is easy to overlook. Planning the work ahead means rooms are finished and cured in time. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in St James's.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

The process
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes as long as the scope needs, from one welfare room to a full building from start to finish. For a job in St James's, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
How to prepare
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

Questions from St James's
Is parking a problem for a job in St James's?
Parking in St James's, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near London Charing Cross station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Can you take on a whole building?
Yes. We work through big sites room by room or floor by floor, so only part of the building is affected at once.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Do you guarantee commercial jobs?
Yes, with our one-year guarantee. Regular gentle cleaning and working extraction help the sealant last.
Can you work around guests in a hotel?
Yes, in most cases. Each visit covers an agreed batch of rooms, working around check-out and check-in where possible.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.
When to call us in St James's
Larger buildings move, and stud walls move more than solid ones. The sealant between walls, trays and fittings absorbs that strain.
Keep an eye out for any of the following:
- Too many rooms to reseal without closing the building
- Rental bathrooms that need resealing between tenants
- Leaking joints in shower rooms and changing areas
- Washroom sealant that looks dirty however often it’s cleaned
Managing a site like Soho Parish CofE Primary School? Then busy washrooms and kitchens can be resealed in phases so they stay open.

What affects the quote in St James's
Jobs vary more than people expect. The main factors:
- When we can work, for business premises
- Whether the work is at height
- The size of the job
- Whether there’s mould to deal with
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- If someone has resealed it before
- Whether it’s a home or a business
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or send us an email.
How the job changes by surface
Hotel bathrooms
We can plan around check-out and check-in times, with the order agreed with your team.
Student & care accommodation
Many accommodation blocks have rows of similar en suites. We agree a programme and work through them steadily.
Should I try it myself first?
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.
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.

As a London address, St James's can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Community buildings like St James’s Church are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.
