- Repeated reseals that do not last
Aftercare tips
So the new joints stay in good condition:
- Pass on the cure time to whoever cleans the rooms
- Encourage users to squeegee shower walls
- Act on lifting sealant before it leaks
- Book larger programmes for quieter times of year
Each room is handed back with its cure time, normally around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, and only replacement fixes it.
Commercial sealant for homes and businesses in Redbourn
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. Typical jobs include joints that need doing before an inspection or audit and water marks on ceilings under bathrooms, on office washrooms & kitchens, rental portfolios and student & care accommodation.
Commercial work around a smaller place like Redbourn generally means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Common questions in Redbourn
Do you cover smaller places like Redbourn?
Yes, Redbourn is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do commercial sealant in Redbourn?
Yes, Redbourn is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can you start early or work out of hours?
It can be arranged for many jobs. The hours are agreed before work starts.
What do you put in the joint?
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 will you be here?
As a guide, most jobs take a morning for a small washroom, and a planned programme for bigger sites. Larger jobs naturally take longer.
Do you hold any approvals?

Where do you work from?

Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Commercial buildings in Redbourn
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a church, hall or community building such as Mount Zion Evangelical Church, halls and community kitchens see heavy use, and their sealant shows it. Rented homes near Harpenden station change hands often, and several rental properties can be resealed on one programme.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Common problems we fix in Redbourn
A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.
Most people get in touch after spotting something like this:
- Large numbers of bathrooms needing the same work
- Split sealant where wet room floors meet walls
- Silicone laid over old silicone by a previous contractor
- Rental bathrooms that need resealing between tenants
Managing a site like Redbourn Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours.

- Whether they’re fully insured
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a single washroom, longer for a whole building. A visit to Redbourn is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start with a site walk to agree the rooms and the timing.
- Room by room, we protect the area and remove all the old sealant.
- Joints are cleaned, treated for mould and dried.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Each room is checked and handed back with its cure time.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Why act early in Redbourn
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, with less disruption and one clear quote. In an older home around Redbourn, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

DIY sealant or a professional job?
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. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
