Great Holcombe Floor Joint Sealing

Floor joints in Great Holcombe need attention? We cut out the old, prepare the joints and apply the right sealant.

  • Grout used at the floor edge instead of sealant
  • Worn sealant at door thresholds
  • Skirting caulk that keeps splitting

Floor joint sealing for Great Holcombe homes and businesses

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

How we handle floor joint sealing in Great Holcombe

We seal floor joints in homes, offices and commercial buildings across Great Holcombe. Each job starts with looking at the floor and the gap, because the right sealant depends on both. We work on wet room & bathroom floors, concrete floor joints and skirting boards, and the jobs we see most are open joints around bathroom floor edges and tiled floors with no room to move.

Older homes in small places like Great Holcombe often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

Each job carries a 12-month guarantee, whatever its size.

The process

There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on the length of joint for a typical job. In a small place like Great Holcombe, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work
  • Tell us about any previous sealing or DIY attempts

When it isn’t the sealant

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

  • A tiled floor that needs relaying
  • Subfloor problems that need a flooring contractor
  • Water getting under the tiles from elsewhere

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Surfaces we seal

  • Skirting boards
  • Commercial floors
  • Thresholds
  • Tiled floors
  • Wet room & bathroom floors
  • Concrete floor joints

Landlords, agents and businesses in Great Holcombe

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for.

Different surfaces, different methods

Concrete floor joints

Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.

Thresholds

Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.

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 for most homes. In a small place like Great Holcombe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

If you look after a church, hall or community building such as Church of St Giles, joints in its floors, skirtings and thresholds need resealing as they wear. In and around Great Holcombe, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.
