About our floor joint sealing in Pratt's Bottom

Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone because it handles water. We work on tiled floors, skirting boards and concrete floor joints, and common reasons people get in touch are tiled floors with no room to move and skirting that has pulled away from the floor.

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, in Pratt's Bottom as anywhere.

You get a one-year guarantee, the same in Pratt's Bottom as everywhere else we work.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Use a well-wrung mop rather than flooding the floor
  • Use furniture pads near skirting
  • Check skirting joints after the heating season
  • Ask before painting over a sealed joint

Do not paint over silicone. If you plan to paint, we will use a paintable product.

Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the floor safer.

Surface by surface

Skirting boards

Skirting gaps are one of the most common floor joints we seal. The old caulk is removed first.

Thresholds

Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.

Pratt's Bottom questions

Is Pratt's Bottom in your area for floor joint sealing?

Yes. Our work covers London and the South East, and Pratt's Bottom is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.

Can parking be tricky for a visit in Pratt's Bottom?

Parking in Pratt's Bottom, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first.

Are you fully insured?

Yes. We’re fully insured, and we can confirm the details when we quote.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little.

Can you reseal concrete floor joints in an industrial unit?

Yes. We clean out the joints and reseal them with a product suited to the floor. Tell us what runs over the floor when you ask for a quote.

Can you use decorators’ caulk instead?

Caulk works on still, dry joints, but it cracks where there’s movement or water. We use a flexible sealant for most skirting and floor joints.

How long does the job take?

As a guide, most jobs take a morning or an afternoon for most homes. Larger jobs naturally take longer, and we’ll say how long yours will take.

When to call us in Pratt's Bottom

Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away.

The problems people normally mention when they call include:

  • Rigid edge joints in tiled floors
  • Tiled floors with no room to move
  • Failed joint filler in concrete floors
  • Dirt and water collecting in open floor joints

As a London address, Pratt's Bottom can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What your quote should include

  • The length of the guarantee
  • Are they insured?
  • What happens if they find a problem under the old sealant
  • When the joint can take water or movement

10 questions to ask before booking

Floor joint sealing around Pratt's Bottom

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. The joint at the skirting or threshold has to allow for that.

Community buildings like All Souls' Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. For site and facilities teams at buildings such as Pratts Bottom Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Leave it or put it right?

Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How we quote for floor joint sealing

For a quick quote, just ask. What matters most is:

  • How much old sealant there is and how hard it is to remove
  • How many rooms, windows or areas are involved
  • Which sealant suits the joint
  • The size of the job

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What we need to know

To make quoting easier, let us know:

  • The address or postcode of the job
  • If someone has resealed it before
  • Photos by email, if that is easy
  • If it’s domestic, commercial or a hotel

For floor joint sealing in Pratt's Bottom, phone 0345 464 0079 or email us. Tell us what the problem is and where, and you will get a clear quote before we start.

How it works

All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a morning or an afternoon for most homes. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Clear items away from the joints we’re working on
  • Let us know about parking restrictions

When it is not the sealant

Some problems need a builder, plumber or other trade rather than us:

  • Floors that are uneven or need levelling
  • Movement too big for a sealant joint
  • Damaged concrete that needs breaking out and repairing
