Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Your questions about commercial sealant in Brightwell Baldwin
What guarantee comes with commercial sealant in Brightwell Baldwin?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you do commercial sealant in Brightwell Baldwin?
Yes, Brightwell Baldwin is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
How long does commercial sealant take?
As a guide, most jobs take a few hours per room, so whole buildings are phased. Larger jobs naturally take longer, and we will tell you how long to expect.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before any work starts.
How long do rooms need to be out of use?
Most areas can be used after around 24 hours. Each room is handed back with the cure time for the product used.
How the job changes by surface
Hotel bathrooms
Early starts or out-of-hours work can be arranged around check-out and check-in.
Retail & leisure sites
Customer washrooms are part of the impression a business makes, and fresh sealant makes them look well kept.
Aftercare tips
So the new joints stay in good condition:
- Plan resealing around quiet periods
- Add sealant to your planned maintenance checks
- Log resealing so you know what’s due
- Report broken fans quickly
Each room is handed back with its cure time, which is generally around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.
Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
What commercial sealant looks like in Brightwell Baldwin
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Icknield Community College, busy washrooms and kitchens can be resealed in phases so they stay open.

When to call us in Brightwell Baldwin
Heavy use means more movement: different weights, constant use and daily cleaning all work at the joint. A tray that is not fully supported soon tears its seal.
Keep an eye out for these signs:
- Repeated reseals that do not last
- Water marks on ceilings under bathrooms
- Washroom sealant that looks dirty however often it’s cleaned
- Joints that need doing before an inspection or audit
If you look after a church, hall or community building such as Church of St Bartholomew, any kitchen and washrooms need the same sealant care as any other building.
What your quote should include
- Whether VAT is included
- Which sealant they’ll use, and why
- When the joint can take water or movement
- How long the guarantee is
How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single washroom, longer for a whole building. Somewhere like Brightwell Baldwin needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start with a site walk to agree the rooms and the timing.
- Each area is protected and the old sealant cut out completely.
- Joints are cleaned, treated for mould and dried.
- New sealant suited to each area is applied and tooled.
- Each room is checked and handed back with its cure time.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
