What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours per room, so whole buildings are phased. In a London area like Lower Holloway, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We walk the site with you and agree the rooms, the order and the hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Advice
Common questions in Lower Holloway
Do you work in hotels near Lower Holloway?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
I let a flat near Caledonian Road & Barnsbury station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How soon can a room be used after resealing?
Follow the cure time we give you, which is usually around 24 hours. Planning the order of rooms keeps that downtime manageable.
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.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.

The location, the problem and the rough size of the job. Photos by email help too.
What we’re called out for in Lower Holloway
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. Worktop and sink joints are often the first to go.
It’s worth asking for a quote if you see:
- Repeated reseals that don’t last
- Tired sealant in let properties
- Too many rooms to reseal without closing the building
- Shower leaks reaching the floor below
For buildings such as St David, its kitchen and washroom sealant needs looking after like anywhere else.
What to look for in a quote
- Who turns up on the day
- How hidden problems are handled
- Which colour the sealant will be
- Is VAT in the price?
Aftercare tips
So the new joints stay in good condition:
- Don’t leave a failed joint until the next refurbishment
- Schedule work around occupancy
- Pass on the cure time to whoever cleans the rooms
- Ask cleaners to go gently on the silicone
Add sealant checks to your planned maintenance. A quick look at each bathroom when rooms are checked spots problems early.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Honest limits
A few problems are outside what sealant work can do:
- Poor ventilation that keeps bringing mould back
- Damaged sanitaryware that needs replacing
- Failed tanking or loose tiles behind the sealant
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
Surfaces we seal

What the job involves on each surface
Welfare facilities
Busy staff showers wear sealant out quickly. We reseal with anti-fungal sanitary silicone, accessible showers included.
Rental portfolios
An empty property is easy to reseal, so the next tenant moves in to clean, sound joints.
