- Tired sealant in let properties
- Large numbers of bathrooms needing the same work

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Commercial sealant in Pottersheath
We fit the work around your building. Rooms can be done one at a time, floor by floor or in batches, and early starts or out-of-hours working can be arranged where it helps. If you are dealing with silicone laid over old silicone by a previous contractor and washrooms that need sorting before an inspection, we can put it right, on office washrooms & kitchens, retail & leisure sites and hotel bathrooms alike.
Somewhere as small as Pottersheath, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

What affects the cost of commercial sealant
We don’t publish a price list, because no two jobs are the same. What we look at:
- The size of the job
- The type of sealant required
- The old material and how stubborn it is
- How easy the joints are to reach
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Where the property is
- A few pictures by email, if you can
- Roughly how big the job is
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved and send you a clear quote.

Advice
Commercial buildings in Pottersheath
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a church, hall or community building such as Church of St Michael and All Angels, halls and community kitchens see heavy use, and their sealant shows it. Schools such as Oaklands Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. For landlords with property near Knebworth station, we can quote for one property or a whole portfolio of rentals.

What happens if it’s left?
A leaking shower in a hotel room or flat above can damage the ceiling below. Then two rooms are out of action, not one. A reseal now avoids that. Where a wall is exposed, as many are in small places like Pottersheath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
