Floor joint sealing for homes and businesses in Streatham Hill
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed with a sealant suited to the movement and traffic. If you have dirt and water collecting in open floor joints and failed joint filler in concrete floors, we can help, whatever the surface.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
Every job comes with a 12-month guarantee.

What happens if it’s left?
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Floor joint sealing around Streatham Hill
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
As a London address, Streatham Hill can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Streatham Hill station, gaps at skirtings and thresholds are worth sealing between tenancies.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

When to call us in Streatham Hill
Caulk is the usual filler for skirting. In a joint that moves or gets wet, it splits, which is why so many skirting joints look broken.
The most common problems we see are:
- Gaps at thresholds between rooms
- Grout cracking in a straight line across a floor
- Failed seals where bathroom floors meet baths and panels
- Caulk that has cracked where the floor moves
Community buildings like Church of St Margaret are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
Questions to ask before you book
- How the colour is chosen
- Whether VAT is included
- What product goes in the joint
- When the joint can take water or movement
What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaks from a failed tanking system
- Movement too big for a sealant joint
- A tiled floor that needs relaying
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal
- Wet room & bathroom floors

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours, depending on the length of joint, including the tidy-up. In a London area like Streatham Hill, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work

Streatham Hill: your questions answered
Can you help a landlord with a rental near Streatham Hill station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can parking be tricky for a visit in Streatham Hill?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Streatham Hill?
Yes. We work in Streatham Hill and the rest of Greater London, as part of our work across South East England, London and Scotland. To book, ring 0345 464 0079 or send us an email.
Can you use decorators’ caulk instead?
Caulk cannot cope with movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.
What does floor joint sealing cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Do you seal warehouse floor joints?
Yes. Concrete floor joints in warehouses and units are part of our work. We’ll talk through the traffic and choose a sealant suited to it.
Why has a gap opened under my skirting?
Generally it’s movement: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible sealant stays closed as the floor moves.
