Floor joint sealing for Biggin Hill homes and businesses

The process

When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work starts. The work generally takes a few hours for most rooms, longer for large commercial floors. 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 look at the gap and the floor type and agree the right sealant.
  2. We take out any old caulk, sealant or grout along the line.
  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.

Getting ready for the visit

  • Tell us about any water getting in
  • Move anything stored near the joints
  • Keep pets and children clear of the area while we work

Advice

Floor joint sealing in Biggin Hill

The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk normally cracks where there’s movement, so we close it with a flexible sealant instead. We work on concrete floor joints, wet room & bathroom floors and tiled floors, and common reasons people get in touch are failed seals where bathroom floors meet baths and panels and perimeter joints in tiled floors filled with grout.

New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Surface by surface

Tiled floors

Tiled floors need movement joints at edges and across large areas. Where needed, a line of grout is replaced with flexible sealant.

Concrete floor joints

Hard wheels break down the edges of open joints. A sealed joint protects the edges and keeps dirt out.

Signs you need floor joint sealing in Biggin Hill

Water and dirt collect in open floor joints. In kitchens and bathrooms, mop water gets into the gap and can reach the subfloor.

If you can see any of these, it’s time to have the joints looked at:

  • Chipped and open joints in warehouse floors
  • Threshold joints that have opened or worn
  • Rigid edge joints in tiled floors
  • Open gaps along the bottom of skirting boards

Biggin Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

10 questions to ask before you book

What sealant work cannot fix

A few problems are outside what sealant work can do:

  • Bouncy or failing floorboards
  • Leaks from a failed tanking system
  • Damaged concrete that needs breaking out and repairing

If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Joints and surfaces we work on

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

Can I do it myself?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Floor joint sealing around Biggin Hill

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. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.

Rented homes near Woldingham station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a building such as Oaklands Primary Academy, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Don’t fill floor joints with caulk where they move or get wet
  • Use furniture pads near skirting
  • Check skirting joints after the heating season
  • Keep floor cleaning water to a minimum at the edges

Silicone sealant isn’t made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.

A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.

Biggin Hill: your questions answered

Can you do floor joint sealing in Biggin Hill?

Yes, Biggin Hill is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.

Is parking a problem for a job in Biggin Hill?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.

Can I do 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.

Is the work guaranteed?

Yes. Every job comes with our 12-month guarantee.

Why has a gap opened under my skirting?

Generally it’s movement: heating drying the timber, or a filler that is too rigid. A flexible sealant stays closed as the floor moves.

Will the old sealant be removed?

Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

Will there be a smell?

Possibly a little. It fades as the sealant cures.
