About our floor joint sealing in Underriver
Concrete floors in warehouses and units have joints that take heavy wear. We reseal them with a product chosen for the movement and the traffic. Common call-outs are for skirting that has pulled away from the floor and rigid edge joints in tiled floors, across thresholds, wet room & bathroom floors and tiled floors.
In a village or hamlet like Underriver, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
There’s a 12-month guarantee on every job.

How the visit works
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours, depending on the length of joint, and we tell you how long to leave it before we go. Somewhere as small as Underriver, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- The joint is tooled neatly and the cure time explained.
Preparing for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Keep children and pets away from the work area

What affects the cost of floor joint sealing
Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Mould in or behind the old joints
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why deal with it now?
Putting new grout into a crack that keeps reappearing doesn’t last. The movement is still there, so the grout fails again. Replacing that line with flexible sealant gives it somewhere to go. Around Underriver, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, 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.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Use a well-wrung mop rather than flooding the floor
- Cone off fresh joints until they’re ready
- Check the sealant is paintable before decorating
- Do not fill floor joints with caulk where they move or get wet
Check the joints after the first winter. Small gaps at the ends can be touched up before they spread.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and stops it getting worse.

Floor joint sealing around Underriver
Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s 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 Margaret, joints in its floors, skirtings and thresholds need resealing as they wear. Schools such as Sevenoaks Preparatory School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Signs you need floor joint sealing in Underriver
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, where a flexible joint should have been.
It’s worth asking for a quote if you see:
- Cracked grout where a tiled floor needs a movement joint
- Open joints that fill with dirt
- Cracked caulk along skirting in bathrooms and kitchens
- Gaps opening between the floor and skirting
