Signs you need floor joint sealing in Dorchester
New floors settle once they’re in use. The edges pull away from the skirting and anything rigid cracks.
Any of these means the joints need attention:
- Threshold joints that have opened or worn
- Chipped and open joints in warehouse floors
- Caulk that has cracked where the floor moves
- Dirt and water collecting in open floor joints
If you look after a building such as Dorchester St Birinus Church of England School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Floor joint sealing for homes and businesses in Dorchester
Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we use a flexible sealant that moves with the floor. We work on commercial floors, skirting boards and wet room & bathroom floors, and common reasons people get in touch are grout used at the floor edge instead of sealant and concrete floor joints that have broken down.
Somewhere as small as Dorchester, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
There’s a 12-month guarantee on every job, whatever its size.

Floor joint sealing around Dorchester
Across Oxfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
Rented homes near Culham station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. Community buildings like Dorchester Abbey are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning or an afternoon for most homes. For a village or hamlet like Dorchester, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Getting ready for the visit
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Related advice
What happens if it’s left?
Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In a small place like Dorchester, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
Why book with us

What we can’t put right
We will always be straight with you, so here’s what new sealant won’t do:
- Cracked or broken concrete slabs
- A tiled floor that needs relaying
- Floors that are uneven or need levelling
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
Where we work in Dorchester
- Skirting boards
- Concrete floor joints
- Commercial floors
- Thresholds
- Wet room & bathroom floors
- Tiled floors
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Do not fill floor joints with caulk where they move or get wet
- Have a cracking tiled floor checked before tiles break
- Look at floor joints each spring
- Keep floor cleaning water to a minimum at the edges
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it while it cures.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.
