DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What happens if it’s left?
Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. A flexible movement joint is the fix. Older cottages and farmhouses around Chandler's Cross can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Surface by surface
Wet room and bathroom floors
In a wet room, the floor-to-wall joint is a key line of defence. We reseal it with a flexible silicone suited to wet areas and we’ll say if the problem looks like more than the joint.
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.
Your questions about floor joint sealing in Chandler's Cross
Can you do floor joint sealing in Chandler's Cross?
Yes, Chandler's Cross is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Chandler's Cross?
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.
How long will you be here?
A typical job takes a few hours, depending on the length of joint, including the preparation. Your quote will say how long we expect yours to take.
What causes gaps between the floor and skirting?
Movement from drying timber and settling floors opens the gap. Rigid fillers split, so we use a flexible sealant.
Do you use a paintable sealant?
On joints you want to paint, yes. Silicone doesn’t take paint.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Use a well-wrung mop rather than flooding the floor
- Check the sealant is paintable before decorating
- Don’t fill floor joints with caulk where they move or get wet
- Lift furniture rather than dragging it across joints
Lift furniture rather than sliding it over sealed joints. Sharp edges can cut the sealant before it has fully cured.
Small gaps are quick to seal. Left alone, they collect dirt and widen.
The process
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. The work usually takes a morning or an afternoon for most homes. Somewhere as small as Chandler's Cross, 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.

Advice
Floor joint sealing around Chandler's Cross
Across Hertfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
If you let a flat or house near Kings Langley station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. Managing a site like York House School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.
