About our floor joint sealing in Wymering

Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant. Typical jobs include grout used at the floor edge instead of sealant and grout cracking in a straight line across a floor, across tiled floors, commercial floors and skirting boards.

If you’ve bought a new home in or near Wymering, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.

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

Signs you need floor joint sealing in Wymering

Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting, then close again in damper months.

These are the problems we are asked about most:

  • Grout cracking in a straight line across a floor
  • Open joints that fill with dirt
  • Chipped and open joints in warehouse floors
  • Caulk that has cracked where the floor moves

If you let a flat or house near Cosham station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Choosing a sealant specialist

How the visit works

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours, depending on the length of joint, depending on the size of the job. A visit to Wymering is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We clear the edges of the floor so the joints are easy to reach.
  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 and smooth it.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • Mention any parking rules near the property
  • Mention any sign-in or site rules at work premises
  • Try not to wet indoor joints just before the visit

Advice

Joints and finishes in Wymering homes

Floors around Portsmouth run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.

If you look after a church, hall or community building such as Church of St Peter and St Paul, joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like Medina Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Aftercare tips

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Cone off fresh joints until they’re ready
  • Walk round the room once a year and look at the edges
  • Use a well-wrung mop rather than flooding the floor
  • Don’t paint over silicone

Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.

Small gaps are quick to seal. Ignored, they fill with dirt and open further and are harder to clean out.

Honest limits

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Cracked or broken concrete slabs
  • Failed waterproofing under a wet room floor
  • Loose, hollow or cracked tiles, which need a tiler

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

What we seal

  • Commercial floors

DIY versus a professional finish

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
