Commercial & hotel sealant in Newington, Kent
Our applicators work in Newington on sealant work for offices, hotels, washrooms and commercial buildings. Old material cut out, joints cleaned and sealed neatly.
- Shower leaks reaching the floor below
- Silicone laid over old silicone by a previous contractor
- Worktop sealant that has shrunk and stained
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Give housekeeping the cure time for every room
- Act on lifting sealant before it leaks
- Include the silicone on your room checklists
- Put a squeegee in each shower
Extract fans need to work. Where a room has no window, the fan is what dries it out, and mould comes back faster without it.
Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
Commercial sealant in Newington, done properly
Guest bathrooms are cleaned every day and used by different people every night, so sealant there has a hard life. Rooms are resealed in batches, keeping most rooms available, with a cure time for each room so housekeeping know when to release it. We work on rental portfolios, welfare facilities and office washrooms & kitchens, and the jobs we see most are whole floors of tired en suites and rental bathrooms that need resealing between tenants.
If you have holiday lets, a converted barn used for business or a community building near Newington, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens on the day
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for a single washroom, longer for a whole building, depending on the amount of work. In a small place like Newington, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we visit and agree the scope, the sequence and the working hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Keep children and pets away from the work area

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
When it isn’t the sealant
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Failed tanking or loose tiles behind the sealant
- A shower tray, bath or basin that’s cracked or broken
- A broken extractor fan behind the mould problem
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Commercial sealant in Newington: local notes
For seaside hotels, guest houses and holiday lets around Newington, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For buildings such as Church of St Nicholas, any kitchen and washrooms need the same sealant care as any other building.

Do you need commercial sealant in Newington?
Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.
The problems people normally mention when they call are:
- Failed joints in office kitchens and tea points
- Whole floors of tired en suites
- Rental bathrooms that need resealing between tenants
- Repeated reseals that do not last

Leave it or put it right?
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 will say so. In a small place like Newington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
