Floor joint sealing in Startop's End, done properly
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. Common call-outs are for threshold joints that have opened or worn and skirting caulk that keeps splitting, across commercial floors, concrete floor joints and wet room & bathroom floors.
Around Startop's End, 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.
Every job is covered by our 12-month guarantee.

How we quote for floor joint sealing
The quote reflects the job in front of us. We look at:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- How many areas need sealing
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What’s wrong with the joints now
- Where the property is
- Roughly how big the job is
- Photos by email, if that’s easy
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.
When something else is needed
A few problems are outside what sealant work can do:
- Large cracks that need a surveyor
- Loose, hollow or cracked tiles, which need a tiler
- Bouncy or failing floorboards
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Surfaces we seal
- Thresholds
- Tiled floors
- Wet room & bathroom floors
- Skirting boards
- Commercial floors
- Concrete floor joints
What the job involves on each surface
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. That line is converted to a flexible joint.
Your questions about floor joint sealing in Startop's End
I let a flat near Tring station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is Startop's End within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
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 you work on commercial floors?
Yes, from warehouses and units to offices and shops. We can plan around your opening times, and out-of-hours work can be arranged.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a morning or an afternoon for most homes. Somewhere like Startop's End needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Related advice
Leave it or put it right?
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. In a small place like Startop's End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What we’re called out for in Startop's End
When a tiled floor has no movement joints, the grout takes the strain. You’ll see a crack running along the grout, showing where a movement joint was needed.
If you can see any of these, it’s time to have the joints looked at:
- Dirt and water collecting in open floor joints
- Failed seals where bathroom floors meet baths and panels
- Caulk that has cracked where the floor moves
- Grout cracking in a straight line across a floor
Managing a site like Marsworth Church of England Infant School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

- How the colour is chosen
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
