Trusted floor joint sealing in Lower Rainham

Floor joint sealing in Lower Rainham

Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints. Typical jobs include cracked grout where a tiled floor needs a movement joint and threshold joints that have opened or worn, on wet room & bathroom floors, tiled floors and thresholds.

Work in a small place like Lower Rainham just needs the journey and access planning, and once on site, the job is the same as anywhere.

You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

FAQs for Lower Rainham

Can you do floor joint sealing in Lower Rainham?

Yes, Lower Rainham is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.

Will you come out to Lower Rainham?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

My floor grout keeps cracking in a line. Can you help?

Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant, giving the floor room to move.

I rent my home. Can I book you?

Yes. Ask your landlord first, and we can send them the quote if that helps.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Signs you need floor joint sealing in Lower Rainham

Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and can reach the subfloor.

The problems people generally mention when they call are:

  • Gaps opening between the floor and skirting
  • Skirting caulk that keeps splitting
  • Failed joint filler in concrete floors
  • Grout cracking in a straight line across a floor

If you look after a building such as Thames View Primary School, entrance and corridor floor joints take a lot of traffic.

Community buildings like Church of St Margaret are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Letting a property close to Rainham (Kent) station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

The process

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on the length of joint. Somewhere like Lower Rainham needs a little journey planning: let us know about lanes, gates and parking. 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. We take out the cracked caulk, grout or old sealant.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor and tooled.
  5. We check the joints and explain the aftercare.

How to prepare

  • Move anything stored near the joints
  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints

Related advice

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

Looking after it afterwards

A little care helps the new joints last. Our advice:

  • Sweep along the edges of the floor
  • Walk round the room once a year and look at the edges
  • Use a well-wrung mop rather than flooding the floor
  • Use furniture pads near skirting

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed while it cures.

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

Different surfaces, different methods

Commercial floors

Commercial floors take more traffic than most homes. The sealant is chosen for the traffic the floor takes.

Tiled floors

Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines in a matching colour.
