Floor joint sealing in Shortlands

DIY sealant or a professional job?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Floor joint sealing for homes and businesses in Shortlands

Across Shortlands, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, because the right sealant depends on both. We work on skirting boards, concrete floor joints and tiled floors, and the jobs we see most are skirting that has pulled away from the floor and dirt and water collecting in open floor joints.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.

A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Surface by surface

Concrete floor joints

Sawn joints in concrete floors control where it cracks. They’re resealed with a product chosen for what runs over them.

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.

Shortlands questions

Can you do floor joint sealing in Shortlands?

Yes, Shortlands is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Is parking an issue for floor joint sealing in Shortlands?

Parking in Shortlands, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.

Are you an approved applicator?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Do you remove the old sealant?

Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Is it OK to seal over old sealant?

No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

When can I walk on the floor?

Follow the cure time we give you. Light use comes first, cleaning and heavy traffic later.

Where are you based?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

The process

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the length of joint. For a job in Shortlands, parking and access are the things to plan: let us know about parking, the floor we will 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. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Do you need floor joint sealing in Shortlands?

Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.

The problems people generally mention when they call are:

  • Caulk that has cracked where the floor moves
  • Failed joint filler in concrete floors
  • Open joints around bathroom floor edges
  • Worn sealant at door thresholds

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

Why it’s worth doing now in Shortlands

The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. In a flat in Shortlands, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

It helps to know what we can’t do:

  • Floors that are uneven or need levelling
  • Concrete repairs beyond the joint
  • Leaks from a failed tanking system

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Joints and finishes in Shortlands homes

Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. 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 is why the skirting and threshold joints need a flexible seal.

Managing a site like Highfield Infants' School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. As a London address, Shortlands can be tricky for parking: let us know about parking bays, permits or a driveway.
