DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
About our floor joint sealing in Chichester
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant coloured to suit the grout. If you are dealing with skirting that has pulled away from the floor and open joints that fill with dirt, we can help, whatever the surface.
Small business units and shops in a town like Chichester have floors that take heavy wear. Threshold and floor joints are best resealed before their edges start breaking away.
All our work is covered by our one-year guarantee.

What else we do in Chichester
Joints and finishes in Chichester homes
Floors around West Sussex run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
For buildings such as Church of St Paul, floor and skirting joints in halls and kitchens wear like any others. Schools such as Lancastrian Infant School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

What affects the cost of floor joint sealing
The quote reflects the job in front of us. We take into account:
- Whether the work is at height
- How many areas need sealing
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- What’s wrong with the joints now
- How we’d reach the joints
- A few pictures by email, if you can

What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours, depending on the length of joint, including the tidy-up. Parking in a town like Chichester is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, the floor type, the gap and the traffic are checked.
- 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.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Clear items away from the joints we’re working on
- Mention any tricky access
- On commercial sites, let us know about site rules

Related advice
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. Replacing that line with flexible sealant gives it somewhere to go. In Chichester, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

Common questions in Chichester
Is floor joint sealing in Chichester guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
I let a flat near Chichester station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
How long does floor joint sealing take?
Typically it takes a morning or an afternoon for most homes. Larger jobs naturally take longer, and we’ll say how long yours will take.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can grout be replaced with sealant on a tiled floor?
In many cases, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant. Loose or cracked tiles need a tiler first.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
What causes gaps between the floor and skirting?
Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.
Signs you need floor joint sealing in Chichester
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits so the gap reappears.
Any of these means the joints need attention:
- Failed seals where bathroom floors meet baths and panels
- Tiled floors with no room to move
- Cracked caulk along skirting in bathrooms and kitchens
- Failed joint filler in concrete floors
Letting a property close to Chichester station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.
