Commercial sealant for homes and businesses in Dulwich
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. Common call-outs are for shower leaks reaching the floor below and tired sealant in let properties, across hotel bathrooms, welfare facilities and student & care accommodation.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Dulwich, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
We stand behind the work with a 12-month guarantee.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a single washroom, longer for a whole building for a typical job. In Dulwich, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we visit and agree the scope, the sequence and the working hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Commercial sealant around Dulwich
There are hotels and other places to stay in and around Dulwich. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Schools such as St Anthony's Catholic Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open. For buildings such as Christ's Chapel of God's Gift, any kitchen and washrooms need the same sealant care as any other building.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Schedule work around occupancy
- Add sealant to your planned maintenance checks
- Keep strong chemicals and scourers off the joints
- Act on lifting sealant before it leaks
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant, with stronger products kept off the bead.
In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
Surface by surface
Hotel bathrooms
Guest bathrooms are resealed room by room or in batches, so most rooms stay available. Each room is handed back with its cure time for housekeeping.
Retail & leisure sites
Customer washrooms are part of the impression a business makes, and fresh sealant makes them look well kept.
When to call us in Dulwich
Staff kitchens and food areas see constant splashing and wiping, so sealant there wears and stains. Worktop and sink joints are often the first to go.
People generally contact us after spotting one of these:
- Worktop sealant that has shrunk and stained
- Mouldy washroom sealant that staff and guests notice
- Tired sealant ahead of a health and safety audit
- Failed floor-level joints in accessible wet rooms
Dulwich is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Dulwich: your questions answered
Do you work in hotels near Dulwich?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can you help a landlord with a rental near West Dulwich station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you work in Dulwich?
Yes. We cover Dulwich and the rest of Greater London. To book, phone 0345 464 0079 or send us an email.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
How long will you be here?
As a guide, most jobs take a few hours per room, so whole buildings are phased. Larger jobs naturally take longer, and we will say how long yours will take.
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 does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
