What the job involves on each surface
Thresholds
Thresholds take daily traffic, so we choose a hard-wearing, flexible product.
Concrete floor joints
Old filler, dust and debris are cleaned out of the joint first. Backing goes in where the depth needs controlling.
When something else is needed
It helps to know what we cannot do too:
- Concrete repairs beyond the joint
- A tiled floor that needs relaying
- Large cracks that need a surveyor
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

FAQs for Nup End Green
Will you come out to Nup End Green?
Yes, Nup End Green is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Knebworth station. Can you help?

Are you fully insured?

Can I add another job to the visit?

What does floor joint sealing cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Look at floor joints each spring
- Don’t paint over silicone
- Keep floor cleaning water to a minimum at the edges
- Don’t fill floor joints with caulk where they move or get wet
Check the joints after the first winter. If anything has opened, it’s easy to reseal.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 fails, we can still redo it.
Landlords, agents and businesses in Nup End Green
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Advice
Do you need floor joint sealing in Nup End Green?
Wheels crossing an unfilled concrete joint chip its edges. Pallet trucks and trolleys knock the edges away.
The problems people normally mention when they call include:
- Gaps between floors and kitchen plinths
- Threshold joints that have opened or worn
- Dirt and water collecting in open floor joints
- Gaps opening between the floor and skirting
Community buildings like Church of St Mary and St Thomas are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
What your quote should include
- How hidden problems are handled
- How the joint is cleaned and prepared
- How the colour is chosen
- Is the old sealant removed completely?
