Custom House is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as St Joachim's Catholic Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Commercial sealant in Custom House, done properly
Office kitchens, staff washrooms and welfare facilities need to be usable every working day. Early starts and out-of-hours work can be arranged to keep disruption down. Each area is handed back with its cure time. We’re often asked to deal with mouldy bathrooms flagged at a tenancy check and leaks from showers into rooms or ceilings below, across welfare facilities, rental portfolios and office washrooms & kitchens.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Custom House, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Big or small, you get the same 12-month guarantee.

Questions from Custom House
Do you work in hotels near Custom House?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you help a landlord with a rental near Custom House station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on the number of rooms. We will confirm how long when we quote.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How we quote for commercial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- How many areas need sealing
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before we start.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- Where the job is, and your postcode
There’s no standard price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.
How the job changes by surface
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.
Rental portfolios
Between tenancies is a good time to reseal, ready for the next tenant.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check the joints during routine room inspections
- Check extract fans are actually running
- Leave squeegees in busy showers
- Tell cleaning staff when each room can be used
Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix, and if anything looks wrong, just phone 0345 464 0079 or email us.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
What we are called out for in Custom House
A rushed reseal between guests rarely lasts. New silicone over old, joints that weren’t dried, or an unsuitable product means the joint fails again soon.
Most people get in touch when they notice one of these:
- Leaking joints in shower rooms and changing areas
- Water marks on ceilings under bathrooms
- Sealant failing again soon after quick repairs
- Too many rooms to reseal without closing the building
For buildings such as St Matthew's Church, any kitchen and washrooms need the same sealant care as any other building.
Before booking anyone
- When the joint can take water or movement
- The length of the guarantee
- Who does the work, and how experienced they are
- How hidden problems are handled
How it works
The work is kept neat and contained to the joints we are treating. The job normally takes a few hours for a single washroom, longer for a whole building, and we explain the cure time before we leave. 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 agree a programme with you: which rooms, in what order, at what times.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
