DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Commercial sealant in East Wickham, done properly
Mouldy or split sealant in a commercial building causes more than a bad impression. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. Common call-outs are for silicone laid over old silicone by a previous contractor and washrooms that need sorting before an inspection, on welfare facilities, hotel bathrooms and rental portfolios.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In East Wickham, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
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.

Why it’s worth doing now in East Wickham
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, keeping disruption down and costs clear. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in East Wickham, the repair is bigger than a sealant job.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Advice
East Wickham: your questions answered
Can parking be tricky for a visit in East Wickham?
Parking in East Wickham, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you cover East Wickham for commercial sealant?

When can guests or staff use the shower again?
Normally after around 24 hours. Each room is handed back with the cure time for the product used.
Does commercial work come with a guarantee?
Yes. We give a 12-month guarantee on every job and are fully insured.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Leave squeegees in busy showers
- Pass on the cure time to whoever cleans the rooms
- Book larger programmes for quieter times of year
- Act on lifting sealant before it leaks
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
A room that cannot be let or used is lost income. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.
What the job involves on each surface
Office washrooms & kitchens
Kitchen and tea point joints are degreased and resealed, using a food-safe sealant by sinks where it’s needed.
Hotel bathrooms
Guest bathrooms are resealed room by room or in batches, keeping most of the hotel open. Each room is handed back with its cure time for housekeeping.
Signs you need commercial sealant in East Wickham
A hotel shower or office washroom is used many times a day, and daily cleaning with strong chemicals wears sealant down. That’s why sealant fails sooner.
Most people get in touch after spotting one of these:
- Leaking joints in shower rooms and changing areas
- Whole floors of tired en suites
- Failed joints in office kitchens and tea points
- Tired sealant in let properties
For landlords with property near Welling station, several rental properties can be resealed on one programme.

Commercial buildings in East Wickham
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
As a London address, East Wickham can be tricky for parking: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as St Mary the Virgin, any kitchen and washrooms need the same sealant care as any other building.
