Floor joint sealing for Mill Hill homes and businesses

Floor joint sealing for homes and businesses in Mill Hill

Where skirting is painted, we can use a flexible sealant that takes paint. For bathrooms and kitchens, silicone is normally the better choice. If you are dealing with worn sealant at door thresholds and failed joint filler in concrete floors, we can put it right, on commercial floors, tiled floors and wet room & bathroom floors alike.

For a new home in or near Mill Hill, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.

We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Signs you need floor joint sealing in Mill Hill

A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands.

The problems people normally mention when they call include:

  • Concrete floor joints that have broken down
  • Perimeter joints in tiled floors filled with grout
  • Open joints that fill with dirt
  • Cracked caulk along skirting in bathrooms and kitchens

For landlords with property near Walmer station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Do I have to be there?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

It depends on the product and the conditions. We give you the times for walking, cleaning and traffic when we finish so you can plan.

How long does floor joint sealing take?

Do you seal kitchen plinths to the floor?

Yes. We cut out any old sealant or caulk and reseal with flexible silicone, colour-matched where it shows.

Are you ARBOMaster approved?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

How the job changes by surface

Tiled floors

The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.

Commercial floors

Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.

Landlords, agents and businesses in Mill Hill

Landlords and letting agents in Mill Hill can book us as well as householders. Resealing between tenancies keeps a property looking cared for.

For anyone letting property in or around Mill Hill, jobs at different addresses can go on one quote. Send us the addresses and the work at each.

How it works

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on the length of joint in most cases. For a job in Mill Hill, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor and tooled.
  5. We check the joints and explain the aftercare.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Clear the area around the work
  • On commercial sites, let us know about site rules

Why deal with it now?

Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. It’s a quick job to seal them now. In an older home around Mill Hill, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Why us?

  • White, clear, grey or coloured to suit, where the product allows
  • Full insurance on every job
  • More than 20 years in sealant work
  • Tidy, careful work

What floor joint sealing looks like in Mill Hill

Across Kent, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

If you look after a church, hall or community building such as St Richard, floor and skirting joints in halls and kitchens wear like any others. Managing a site like St Mary's Catholic Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

When it is not the sealant

Before you book, it’s worth knowing the limits:

  • Cracked or broken concrete slabs
  • Tiles that have lifted or broken
  • Bouncy or failing floorboards

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
