Floor joint sealing for homes and businesses in Hexton
Thresholds are where two floors, or a floor and a door, meet. We seal them with a flexible sealant suited to the floor finishes either side in a colour to suit. We work on wet room & bathroom floors, skirting boards and tiled floors, and the jobs we see most are floor edges that trap water and grime and cracked caulk along skirting in bathrooms and kitchens.
Older homes in small places like Hexton often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, whatever its size.

Hexton: your questions answered
Do you work for landlords with property near Harlington station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Hexton?
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 use a paintable sealant?
If you tell us beforehand, yes. We use a paintable flexible sealant on joints you plan to paint.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
When can I walk on the floor?
We will tell you before we leave. That depends on the product, and walking on it generally comes before mopping or wheeled traffic.
Where are you based?
We work from Crawley. Our applicators cover Hexton.
Do you seal floor joints in bathrooms and kitchens?
Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone.
What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a morning or an afternoon for most homes. Somewhere as small as Hexton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- 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
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

Do you need floor joint sealing in Hexton?
Caulk is the usual filler for skirting. It cracks where there’s movement or water so the gap reappears.
Most people get in touch after spotting something like this:
- Concrete floor joints that have broken down
- Open gaps along the bottom of skirting boards
- Open joints that fill with dirt
- Gaps at thresholds between rooms
If you look after a church, hall or community building such as Church of St Faith (Church of England), floor and skirting joints in halls and kitchens wear like any others.

Why act early in Hexton
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. Around Hexton, 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 depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Joints and finishes in Hexton homes
Floors around Hertfordshire 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.
Rented homes near Harlington station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. For site and facilities teams at buildings such as Hexton Junior Mixed and Infant School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
