DIY versus a professional finish

Commercial sealant for homes and businesses in Kennington
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. We work on office washrooms & kitchens, retail & leisure sites and rental portfolios, and the jobs we see most are water marks on ceilings under bathrooms and split sealant around staff kitchen worktops and sinks.
In a smaller place like Kennington, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
There’s a 12-month guarantee on every job, large or small.

What commercial sealant looks like in Kennington
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Kennington has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Community buildings like Church of St Mary are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. Managing a site like Kennington Church of England Academy? Then washroom and kitchen sealant can be programmed around term times or opening hours.

Why deal with it now?
Guests and staff judge a building by its bathrooms. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing will not fix it. New sealant does. Around Kennington, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

How we quote for commercial sealant
Every job gets its own quote. These are the things that affect it:
- When we can work, for business premises
- The product the joint needs
- Access and height
- How many rooms, windows or areas are involved
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the property is
- The rough size of the job
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.
How to look after the new joints
To keep the joints looking good and working properly:
- Check the joints during routine room inspections
- Pass on the cure time to whoever cleans the rooms
- Keep a record of which rooms were resealed and when
- Book larger programmes for quieter times of year
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant.
In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- Fire risk assessments or certification
- Failed tanking or loose tiles behind the sealant
- Water coming from plumbing rather than sealant
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of rooms. Parking around Kennington is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before we start.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
