We quote each job individually. These are the things that affect it:

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear quote before any work starts.

  • The rough size of the job

Floor joint sealing for homes and businesses in Hither Green

In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. If you’re dealing with gaps opening between the floor and skirting and perimeter joints in tiled floors filled with grout, we can put it right.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

There’s a 12-month guarantee on every job, whatever its size.

What happens on the day

We keep the work tidy and contained to the joints we’re treating. The job generally takes a few hours, depending on the length of joint. In a London area like Hither Green, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area
  • Mention any parking rules near the property

Why it’s worth doing now in Hither Green

Left open, concrete joints break down under traffic. Resealing it early protects the edges. In a flat in Hither Green, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Why us?

  • Sealant colour chosen to suit
  • ARBOMaster approved applicator
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Any old sealant cut out fully, not covered over

Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.

Can you quote for more than one area?

Yes. More than one area can go on one quote.

Do you seal floor joints in bathrooms and kitchens?

Yes. These joints get wet every time the floor is cleaned, so we seal them with silicone suited to wet areas.

Can new sealant go over the old?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Is the work guaranteed?

Yes. There’s a 12-month guarantee on every job, large or small.

My floor grout keeps cracking in a line. Can you help?

In many cases, yes. We replace the grout along a suitable line with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.

Skirting boards

Skirting-to-floor joints are a regular job for us. The old caulk is removed first so the bead sits on a clean surface.

What floor joint sealing looks like in Hither Green

Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

If you look after a church, hall or community building such as Church of St Swithun, joints in its floors, skirtings and thresholds need resealing as they wear. As a London address, Hither Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Common problems we fix in Hither Green

When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, showing where a movement joint was needed.

Look out for these signs:

  • Concrete floor joints that have broken down
  • Open joints that fill with dirt
  • Gaps opening between the floor and skirting
  • Threshold joints that have opened or worn

For site and facilities teams at buildings such as Brindishe Manor School, entrance and corridor floor joints take a lot of traffic.

Before booking anyone

  • What insurance they hold
  • How long to leave it before use
  • The length of the guarantee
  • Is the old sealant removed completely?
