Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Act on lifting sealant before it leaks
- Plan resealing around quiet periods
- Add sealant to your planned maintenance checks
- Leave squeegees in busy showers
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, and only replacement fixes it.
What happens if it’s left?
Sealant work is quick by the room: it takes a few hours per area, with larger sites planned over several visits. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a small place like The City, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.
What you get with us

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a single washroom, longer for a whole building, depending on the size of the job. In a small place like The City, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We clean the joints, treat any mould and let them dry.
- New sealant suited to each area is applied and tooled.
- We check every room and give its cure time for housekeeping.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Advice
Commercial buildings in The City
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Schools such as Radnage Church of England Primary School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours. For buildings such as Church of St Paul, any kitchen and washrooms need the same sealant care as any other building.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How the job changes by surface
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. Anti-fungal sanitary silicone is used throughout, including accessible wet rooms.
Office washrooms & kitchens
Staff toilets, washrooms and kitchens get constant use, so we can work early or out of hours where that can be arranged. Basins, urinals, worktops and sinks are all resealed.
Do you need commercial sealant in The City?
A rushed reseal between guests rarely lasts. New silicone over old, joints that weren’t dried, or an unsuitable product means the joint fails again soon.
Keep an eye out for these signs:
- Large numbers of bathrooms needing the same work
- Silicone laid over old silicone by a previous contractor
- Mouldy bathrooms flagged at a tenancy check
- Water marks on ceilings under bathrooms
For landlords with property near Saunderton station, several rental properties can be resealed on one programme.
