Floor joint sealing for homes and businesses in Grange Mills
We seal floor joints in homes, offices and commercial buildings across Grange Mills. We start by checking the floor type and the joint, since that decides which sealant suits. We work on concrete floor joints, 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 failed joint filler in concrete floors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about floor joint sealing in Grange Mills
Can parking be tricky for a visit in Grange Mills?
Parking in Grange Mills, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near Balham station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours, depending on the length of joint. We’ll give you a better idea when we quote.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can I add another job to the visit?
Yes. Just list everything you need.
Can sealant along the skirting be painted?
For painted skirting, we use a flexible product that can be painted. Silicone won’t take paint, so we use it where the joint stays unpainted.
Can you seal where the floor meets the bath panel?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Keep dirt out of the joints
- Check skirting joints after the heating season
- Do not paint over silicone
- Act on grout cracks that run in a straight line
Do not paint over silicone. If you plan to paint, we will use a paintable product.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier.
What happens on the day
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for most rooms, longer for large commercial floors. In Grange Mills, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First we check the joint and the floor and agree which sealant suits it.
- We take out any old caulk, sealant or grout along the line.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- 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 tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

Advice
Landlords, agents and businesses in Grange Mills
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What the job involves on each surface
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. We talk through the traffic and choose a sealant suited to it.

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy

- Where the job is, and your postcode
- Whether it has been sealed before
We quote each job on its own. Just call 0345 464 0079 or drop us an email with the details and send photos if you have them.
Floor joint sealing around Grange Mills
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
If you look after a building such as Henry Cavendish Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Grange Mills is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Balham station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Why it’s worth doing now in Grange Mills
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a flat in Grange Mills, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
