Floor joint sealing for homes and businesses in Upper Upnor
Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. We are often asked to deal with grout used at the floor edge instead of sealant and open joints that fill with dirt, across concrete floor joints, skirting boards and tiled floors.
Around Upper Upnor, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, large or small.

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a morning or an afternoon for most homes in most cases. Somewhere as small as Upper Upnor, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and smooth it.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Advice
Looking after it afterwards
Aftercare is simple:
- Avoid sloshing water against skirting
- Mark off resealed joints in warehouses
- Check the sealant is paintable before decorating
- Check skirting joints after the heating season
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up before they spread.
Small gaps are quick to seal. Ignored, they fill with dirt and open further.
Upper Upnor: your questions answered
Will you come out to Upper Upnor?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Upper Upnor for floor joint sealing?
Yes, Upper Upnor is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work on commercial floors?
Yes. Concrete floor joints in warehouses and units are part of our work. The product is chosen for the traffic the floor takes.
Why does the gap under my skirting keep coming back?
Normally it’s movement: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible bead keeps up with the movement.
What does floor joint sealing cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Will I be able to paint over the new joint?
On joints you want to paint, yes. Silicone in bathrooms and kitchens cannot be painted.
What information do you need?
A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
What floor joint sealing looks like in Upper Upnor
Across Medway, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
If you let a flat or house near Strood station, a tidy floor and skirting joint helps a rental look ready for the next tenant. Community buildings like St Philip & St James are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What affects the cost of floor joint sealing
There’s no set price list, because jobs vary so much. The quote depends on:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Whether the work is at height
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.

Surface by surface
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. We rake out any grout there and reseal.
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.

When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before any work starts. It will not solve:
- Failed waterproofing under a wet room floor
- Large cracks that need a surveyor
- Subfloor problems that need a flooring contractor
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

Do you need floor joint sealing in Upper Upnor?
Caulk is the usual filler for skirting. In a joint that moves or gets wet, it splits so the gap reappears.
Signs it’s time to call us include:
- Tiled floors with no room to move
- Skirting that has pulled away from the floor
- Failed joint filler in concrete floors
- Dirt and water collecting in open floor joints
Schools such as Wainscott Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.

Why deal with it now?
Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Around Upper Upnor, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
