Southington Commercial Sealant
Professional commercial sealant in and around Southington, with old sealant always removed completely.
- Joints that need doing before an inspection or audit
- Rental bathrooms that need resealing between tenants
- Split sealant where wet room floors meet walls
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Put a squeegee in each shower
- Note the date each area was done
- Give housekeeping the cure time for every room
- Act on lifting sealant before it leaks
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, before they become leaks that take the room out of use.

How long do rooms need to be out of use?

Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Why deal with it now?
Room by room, the work is quick: it takes a few hours per room, so whole buildings are phased. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Older cottages and farmhouses around Southington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What you get with us
- You choose the colour before work begins
- White, clear, grey or another colour, product permitting

Different surfaces, different methods
Office washrooms & kitchens
Kitchen and tea point joints are degreased and resealed, with a food-safe product beside sinks where needed.
Hotel bathrooms
In a hotel, every bathroom is used and cleaned daily, so we use anti-fungal sanitary silicone and finish joints smooth for easy cleaning.
DIY versus a professional finish
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Do you need commercial sealant in Southington?
A hotel shower or office washroom is used many times a day, and daily cleaning with strong chemicals wears sealant down. So the silicone ages faster than it would at home.
It’s worth asking for a quote if you see:
- Mouldy bathrooms flagged at a tenancy check
- Washrooms that need sorting before an inspection
- Too many rooms to reseal without closing the building
- Split sealant around staff kitchen worktops and sinks
Community buildings like Church of St Mary are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.
