Commercial & hotel sealant in Upper Common, Hampshire
Commercial sealant across Upper Common and nearby, with every bit of old sealant taken out first.
- Repeated reseals that do not last
- Shower leaks reaching the floor below
- Mouldy washroom sealant that staff and guests notice
Why deal with it now?
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. If something else is wrong, we’ll say so. Older cottages and farmhouses around Upper Common can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

How we handle commercial sealant in Upper Common
Guest bathrooms are cleaned every day and used by different people every night, so sealant wears out faster than it would at home. Rooms are resealed in batches, so only a few are out of use at once. We work on welfare facilities, retail & leisure sites and student & care accommodation, and common reasons people get in touch are sealant failing again soon after quick repairs and leaking joints in shower rooms and changing areas.
Somewhere as small as Upper Common, 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 with the work, just as it does everywhere we cover.

What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours per room, so whole buildings are phased. Somewhere like Upper Common needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep a record of which rooms were resealed and when
- Put a squeegee in each shower
- Check extract fans are actually running
- Schedule work around occupancy
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
