Floor joint sealing in Hudnall
Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on commercial floors, concrete floor joints and thresholds, and people most often call us about dirt and water collecting in open floor joints and gaps opening between the floor and skirting.
Around Hudnall, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. Most jobs take a few hours for most rooms, longer for large commercial floors. For a village or hamlet like Hudnall, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied.
- We check the joints and explain the aftercare.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Looking after it afterwards
So the new joints stay in good condition:
- Walk round the room once a year and look at the edges
- Don’t fill floor joints with caulk where they move or get wet
- Mark off resealed joints in warehouses
- Ask before painting over a sealed joint
Lift furniture rather than sliding it over sealed joints. Sharp edges can cut the sealant especially in the first few days.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.
What affects the cost of floor joint sealing
The quote reflects the job in front of us. We take into account:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Access and height
- How much old sealant there is and how hard it is to remove
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Where the job is, and your postcode
- The problem you’ve noticed
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What else we do in Hudnall
What the job involves on each surface
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. We rake out any grout there and reseal.
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is generally better.
Why deal with it now?
Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Around Hudnall, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- Tidy, careful work
- More than 20 years in sealant work
- We never seal over old sealant
- Sanitary silicone with an anti-fungal additive in wet areas
