Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep extractor fans working and serviced
- Encourage users to squeegee shower walls
- Keep strong chemicals and scourers off the joints
- Keep a record of which rooms were resealed and when
Strong chemicals and scourers wear silicone out faster. Ask cleaners to use mild products and soft cloths on the sealant.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.

What commercial sealant looks like in Park Street
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For landlords with property near Park Street station, we can quote for one property or a whole portfolio of rentals. Managing a site like Park Street Church of England Voluntary Aided Primary School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. If you look after a church, hall or community building such as Church of the Holy Trinity, any kitchen and washrooms need the same sealant care as any other building.

Common questions in Park Street
Can you do commercial sealant in Park Street?
Yes. Our work covers London and the South East, and Park Street is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
I let a flat near Park Street station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you take on large, multi-room jobs?
Yes. We work through big sites room by room or floor by floor, so only part of the building is affected at once.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we will ask.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Is commercial work guaranteed?
Yes. Every job, domestic or commercial, carries our one-year guarantee.
How long does commercial sealant take?
As a guide, most jobs take a few hours per area, with larger sites planned over several visits. Bigger jobs take longer, and we’ll say how long yours will take.
Is out-of-hours working possible?
In many cases. Let us know when the building is quietest, and we will see what can be arranged.
Leave it or put it right?
A quick bead over the old sealant might get a room back in use today, but it will not bond, and it lifts again soon. Doing it properly once is less disruptive than doing it badly twice. In a small place like Park Street, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

- We walk the site with you and agree the rooms, the order and the hours.
- Room by room, we protect the area and remove all the old sealant.
- We clean the joints, treat any mould and let them dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
How to prepare

Related advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
