Kennington questions
Can you help a landlord with a rental near Radley station?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Kennington?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How long will you be here?
Typically it takes a few hours per area, with larger sites planned over several visits. Bigger jobs take longer.
What does commercial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you work around guests in a hotel?
Yes. We agree a batch of rooms for each visit.

Office washrooms & kitchens

Rental portfolios
An empty property is easy to reseal, ready for the next tenant.
What affects the quote in Kennington
The quote reflects the job in front of us. We take into account:
- The number and length of the joints
- Which sealant suits the joint
- Whether there’s mould to deal with
- How easy the joints are to reach
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- Whether it’s a home or a business
- Photos by email, if that is easy
- The rough size of the job
For a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before work begins.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Leaking pipework, valves or wastes (a plumber’s job)
- Cracked trays or baths rather than failed joints
- Extraction that isn’t working, which needs an electrician or ventilation contractor
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Welfare facilities
- Student & care accommodation
- Hotel bathrooms
- Office washrooms & kitchens
- Retail & leisure sites
- Rental portfolios
When to call us in Kennington
Wet rooms and accessible showers are designed for the whole floor to get wet, so the joints at floor level are under water often. A failed joint there can soon let water into the floor or walls.
Signs it’s time to call us include:
- Tired sealant in let properties
- Sealant failing again soon after quick repairs
- Mouldy washroom sealant that staff and guests notice
- Too many rooms to reseal without closing the building
For buildings such as St Swithun's Church, any kitchen and washrooms need the same sealant care as any other building.
Before you book anyone
- Which colour the sealant will be
- What preparation is included
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per room, so whole buildings are phased. In a smaller place like Kennington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

Workplaces and buildings in Kennington
Hard water is the norm across most of the South East, so limescale builds up 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.
Rented homes near Radley station change hands often, and several rental properties can be resealed on one programme. For site and facilities teams at buildings such as St Swithun's CofE Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
Kennington is about 3 miles south of Oxford, in Oxfordshire. Kennington gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Kennington is one of 443 towns and villages in Oxfordshire we cover for commercial sealant.

Near you in Kennington
In Kennington, that means homes and buildings near The Oxford Academy, Emmanuel Christian School and The Tandem pub. The closest station to Kennington is Radley station, about 1.8 miles south.

Why deal with it now?
Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Homes in smaller places like Kennington can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

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 does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
