Floor joint sealing for homes and businesses in Highmoor
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant coloured to suit the grout. If you’re dealing with cracked caulk along skirting in bathrooms and kitchens and failed joint filler in concrete floors, we can help.
Around Highmoor, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, in Highmoor and everywhere else we cover.

What floor joint sealing looks like in Highmoor
Across Oxfordshire, 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.
Rented homes near Henley-On-Thames station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a church, hall or community building such as Church of St Paul, joints in its floors, skirtings and thresholds need resealing as they wear.

Highmoor: your questions answered
Do you work for landlords with property near Henley-On-Thames station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Will you come out to Highmoor?
Yes, Highmoor is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long does the job take?
Typically it takes a morning or an afternoon for most homes. Larger jobs naturally take longer.
Why has a gap opened under my skirting?
Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you use decorators’ caulk instead?
Caulk can’t cope with movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.

What else we do in Highmoor
What happens if it’s left?
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. Around Highmoor, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Surface by surface
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it where it suits the floor.
Wet room and bathroom floors
Bathroom floor edges get wet at every clean. A neat silicone joint keeps it out.
Common problems we fix in Highmoor
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits, which is why so many skirting joints look broken.
These are the problems we’re asked about most:
- Gaps between floors and kitchen plinths
- Concrete floor joints that have broken down
- Gaps at thresholds between rooms
- Caulk that has cracked where the floor moves
Managing a site like Stoke Row Church of England School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
