Floor joint sealing in Charlton
A threshold joint has to cope with feet, movement and sometimes water. We seal them with a flexible sealant suited to the floor finishes either side so the joint stays neat. We work on thresholds, tiled floors and commercial floors, and people most often call us about open joints around bathroom floor edges and worn sealant at door thresholds.
For a small place like Charlton, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job.

Do you need floor joint sealing in Charlton?
When a tiled floor has no movement joints, the grout takes the strain. You’ll see a crack running along the grout, where a flexible joint should have been.
The problems people generally mention when they call include:
- Tiled floors with no room to move
- Gaps opening between the floor and skirting
- Gaps at thresholds between rooms
- Skirting caulk that keeps splitting
For buildings such as Church of St Mary Magdalene, joints in its floors, skirtings and thresholds need resealing as they wear.

What floor joint sealing looks like in Charlton
Across Surrey, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
If you look after a building such as Littleton CofE Infant School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Letting a property close to Upper Halliford station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant.

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours, depending on the length of joint. For a village or hamlet like Charlton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- We take out any old caulk, sealant or grout along the line.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- The sealant goes in, chosen for the floor and coloured to suit it.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work

How we quote for floor joint sealing
Call for a quick quote. The main things that affect it are:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Mould in or behind the old joints
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Asking for a quote
To make quoting easier, let us know:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
Surface by surface
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is normally better.
Commercial floors
In commercial buildings, we can plan floor joint work around opening hours. Out-of-hours working can be arranged if the floor is busy.

Your questions about floor joint sealing in Charlton

What does floor joint sealing cost?
We don’t publish prices, because the cost 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.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
When can I walk on the floor?
It depends on the product and the conditions. Before we leave, we tell you when it can be walked on, mopped and driven over so you can plan.
How long will you be here?
Typically it takes a few hours, depending on the length of joint. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Will I be able to paint over the new joint?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone will not take paint, so it’s kept for wet areas and unpainted joints.
DIY versus a professional finish
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, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Looking after it afterwards
After the cure time, these simple habits help:
- Avoid caulk in bathrooms and kitchens
- Avoid sloshing water against skirting
- Don’t slide heavy items over sealed joints
- Act on grout cracks that run in a straight line
Keep off the joint for the time we give you. Light foot traffic is usually fine sooner than wet cleaning or wheels.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the floor safer.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
