Floor joint sealing for homes and businesses in South Wonston

Across South Wonston, we seal floor and skirting joints in homes and businesses. Each job starts with looking at the floor and the gap, because the right sealant depends on both. We work on wet room & bathroom floors, skirting boards and thresholds, and the jobs we see most are skirting that has pulled away from the floor and threshold joints that have opened or worn.

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

Whatever the size of the job, it’s backed by our 12-month guarantee.

Honest limits

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Floors that are uneven or need levelling
  • Cracked or broken concrete slabs
  • Failed waterproofing under a wet room floor

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

  • Tiled floors

Signs you need floor joint sealing in South Wonston

When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, where a flexible joint should have been.

Any of these means the joints need attention:

  • Rigid edge joints in tiled floors
  • Cracked grout where a tiled floor needs a movement joint
  • Gaps opening between the floor and skirting
  • Open joints around bathroom floor edges

Community buildings like St Margaret's are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

How to choose a mastic man

Why act early in South Wonston

Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job in most rooms. In a small place like South Wonston, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What floor joint sealing looks like in South Wonston

Floors around Hampshire 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 Winchester station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. Schools such as South Wonston Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic.

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Cone off fresh joints until they’re ready
  • Keep dirt out of the joints
  • Keep caulk for dry, still joints only
  • Avoid sloshing water against skirting

Don’t paint over silicone. If the joint will be painted, tell us beforehand so we use a paintable sealant.

Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.

Wet room and bathroom floors

Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone that keeps water out.

Concrete floor joints

Hard wheels break down the edges of open joints. A sealed joint protects the edges and stops debris collecting.
