How we handle floor joint sealing in Niton
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. If you’re dealing with grout cracking in a straight line across a floor and open gaps along the bottom of skirting boards, we can help, on wet room & bathroom floors, skirting boards and thresholds alike.
Around Niton, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, you get the same one-year guarantee in Niton and across the Isle of Wight.

Floor joint sealing around Niton
Across the Isle of Wight, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. That’s why the skirting and threshold joints need a flexible seal.
For buildings such as Church of St. John the Baptist, floor and skirting joints in halls and kitchens wear like any others. For site and facilities teams at buildings such as Niton Primary School, entrance and corridor floor joints take a lot of traffic.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most rooms, longer for large commercial floors. Somewhere like Niton needs a little journey planning: 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.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- The sealant goes in, chosen for the floor and coloured to suit it.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Clear items away from the joints we’re working on
Ask for a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Advice
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Check skirting joints after the heating season
- Avoid caulk in bathrooms and kitchens
- Keep heavy wheels off new concrete joints until cured
- Do not paint over silicone
Keep off the joint for the time we give you. Feet are normally fine before mopping or wheeled traffic.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
Quotes for floor joint sealing in Niton
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites

- How many rooms, windows or areas are involved
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
What we need to know
To help us quote quickly, let us know:
- The rough size of the job
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- The type of property
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
What happens if it’s left?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant stretches instead, so the joint stays closed. In a small place like Niton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Do you cover smaller places like Niton?
Yes, Niton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are you insured?
Yes. We’re fully insured.
Will it make a mess?

Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will I be able to paint over the new joint?
If you tell us beforehand, yes. Joints that will be painted get a paintable product.
What does floor joint sealing cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How the job changes by surface
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.
Wet room and bathroom floors
Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone.
When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Structural movement or subsidence
- Cracked or broken concrete slabs
- Failed waterproofing under a wet room floor
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Skirting boards

What else we do in Niton
Can I do it myself?
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. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
