Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
About our commercial sealant in Mark Hall South
In a hotel, office or washroom, failed sealant is more than an eyesore. It’s a cleaning problem, a leak risk and something guests and staff notice. We reseal bathrooms, washrooms, welfare areas and kitchens so they look cared for again. If you are dealing with mouldy washroom sealant that staff and guests notice and sealant failing again soon after quick repairs, we can put it right, whatever the surface.
Around a place like Mark Hall South, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.
All our work is covered by our one-year guarantee.

Commercial sealant in Mark Hall South: local notes
Harlow, which Mark Hall South is part of, is one of England’s post-war new towns. Like the other new towns, Harlow was planned with its own areas for industry and business, so there are offices, units and workplaces not far from home. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. 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.
Schools such as Cooks Spinney Primary Academy and Nursery are buildings too, and 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 St Andrew's Methodist Church, any kitchen and washrooms need the same sealant care as any other building. For landlords with property near Harlow Town station, several rental properties can be resealed on one programme.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Leave squeegees in busy showers
- Check extract fans are actually running
- Plan resealing around quiet periods
- Get split or lifting joints looked at early
Strong chemicals and scourers wear silicone out faster. Ask cleaners to use mild products and soft cloths on the sealant, with stronger products kept off the bead.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.
What happens on the day
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a single washroom, longer for a whole building. For a job in Mark Hall South, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
