Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

- Silicone laid over old silicone by a previous contractor
- Joints that need doing before an inspection or audit

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours per room, so whole buildings are phased for a typical job. For a job in Nash Mills, 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.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

What happens if it’s left?
Sealant is easy to forget until an audit or inspection is due. Planning the work ahead means rooms are finished and cured in time. In a smaller place like Nash Mills, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.
Why us?
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- An ARBOMaster approved applicator

Commercial sealant in Nash Mills: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Nash Mills is part of Hemel Hempstead, one of the post-war new towns. Like the other new towns, Hemel Hempstead was planned with its own areas for industry and business, so there are offices, units and workplaces not far from home. Each has washrooms, kitchens and fire-rated joints to keep in order.
If you look after a church, hall or community building such as Church of St Mary, its kitchen and washroom sealant needs looking after like anywhere else. Managing a site like Nash Mills Church of England Primary School? Then busy washrooms and kitchens can be resealed in phases so they stay open.
