Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Vacuum floor joints regularly to stop grit building up
  • Do not fill floor joints with caulk where they move or get wet
  • Keep floor cleaning water to a minimum at the edges
  • Use furniture pads near skirting

Keep off the joint for the time we give you. Light foot traffic is normally fine sooner than wet cleaning or wheels.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.

Floor joint sealing in Wilmington

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. If you’re dealing with gaps between floors and kitchen plinths and open gaps along the bottom of skirting boards, we can put it right.

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

Your job is guaranteed for a year, as with all our work.

Thresholds

A threshold is where floors and frames meet. A flexible sealant suits both floor finishes.

Common questions in Wilmington

I let a flat near Crayford station. Can you help?

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.

Do you cover Wilmington for floor joint sealing?

Yes. Our work covers London and the South East, and Wilmington is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.

Will you leave a mess?

Can you seal where the floor meets the bath panel?

Yes. Floor edges in bathrooms and kitchens get wet at every clean, so we seal them with silicone suited to wet areas.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

How long does floor joint sealing take?

Typically it takes a few hours, depending on the length of joint. Larger jobs naturally take longer, and we’ll say how long yours will take.

Do you have insurance?

Yes. We’re fully insured.

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

Joints and finishes in Wilmington homes

Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

For landlords with property near Crayford station, a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a building such as Wilmington Grammar School for Girls, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Can I do it myself?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

What we do, step by step

At the end, we look at the finished work together. The work normally takes a few hours for most rooms, longer for large commercial floors, depending on the amount of work. Somewhere like Wilmington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied.
  5. We check the joints and explain the aftercare.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we are working on

What sealant work can’t fix

To be straight with you, some problems need a different trade:

  • Water getting under the tiles from elsewhere
  • Tiles that have lifted or broken
  • Floors that are uneven or need levelling

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

What we seal

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

Common problems we fix in Wilmington

Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open, then close again in damper months.

These are the problems we’re asked about most:

  • Open joints around bathroom floor edges
  • Threshold joints that have opened or worn
  • Rigid edge joints in tiled floors
  • Concrete floor joints that have broken down

If you look after a church, hall or community building such as St Barnabas, floor and skirting joints in halls and kitchens wear like any others.

What your quote should include

  • Are they insured?
  • Is the old sealant removed completely?
  • Who does the work, and how experienced they are
  • Which colour the sealant will be
