Commercial sealant for homes and businesses in Knockholt
In a hotel, office or washroom, failed sealant is more than an eyesore. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. Common call-outs are for washrooms that need sorting before an inspection and rental bathrooms that need resealing between tenants, across retail & leisure sites, office washrooms & kitchens and welfare facilities.
For holiday lets, converted business premises or a community building near Knockholt, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Leave it or put it right?
A quick bead over the old sealant might get a room back in use today, but it will not bond, and it lifts again soon. Doing it properly once is less disruptive than doing it badly twice. Where a wall is exposed, as many are in small places like Knockholt, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why us?
- Arbo and Everbuild products
- You choose the colour before work begins
- ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet

Common problems we fix in Knockholt
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. A failed joint there can soon let water into the floor or walls.
Signs it’s time to call us include:
- Mouldy bathrooms flagged at a tenancy check
- Shower leaks reaching the floor below
- Washrooms that need sorting before an inspection
- Whole floors of tired en suites
Rented homes near Knockholt station change hands often, and we can quote for one property or a whole portfolio of rentals.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of rooms. For a village or hamlet like Knockholt, the journey is planned in advance: 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 by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

DIY versus a professional finish
If you are set on DIY, put the effort into 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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What affects the quote in Knockholt
We do not publish a price list, because no two jobs are the same. The quote depends on:
- When we can work, for business premises
- The size of the job
- The old material and how stubborn it is
- Which sealant suits the joint
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- The type of property
- The problem you’ve noticed
- Any access issues, like height or stairs
Every job is quoted individually. Simply phone 0345 464 0079 or send us an email and describe the job, and pictures are welcome.

What the job involves on each surface
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. We renew it in one tidy, continuous bead.
