North Woolwich Floor Joint Sealing
Problem with your floor joints in North Woolwich? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Failed joint filler in concrete floors
- Rigid edge joints in tiled floors
- Gaps at thresholds between rooms
How we handle floor joint sealing in North Woolwich
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. Typical jobs include open joints that fill with dirt and gaps opening between the floor and skirting, on concrete floor joints, thresholds and commercial floors.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Different surfaces, different methods
Commercial floors
Commercial washrooms and kitchens have floor joints that get wet constantly. We reseal them with a sealant suited to wet areas.
Skirting boards
If the skirting is painted, a paintable flexible sealant works well. In wet rooms and kitchens, silicone is usually better.
North Woolwich questions
Can parking be tricky for a visit in North Woolwich?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you do floor joint sealing in North Woolwich?
Yes, North Woolwich is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Can sealant along the skirting be painted?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone won’t take paint, so it’s kept for wet areas and unpainted joints.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you need floor joint sealing in North Woolwich?
New floors settle once they’re in use. Gaps at the edges appear in the first year or so.
If you can see any of these, it’s time to have the joints looked at:
- Rigid edge joints in tiled floors
- Open joints around bathroom floor edges
- Skirting that has pulled away from the floor
- Chipped and open joints in warehouse floors
North Woolwich is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before booking
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
- Whether you can choose the colour
- Are they insured?
Joints and finishes in North Woolwich homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. 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. That’s why the skirting and threshold joints need a flexible seal.
Community buildings like St John's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. If you look after a building such as Oasis Academy Silvertown, floor and threshold joints in busy corridors wear quickly and are best resealed early.

DIY versus a professional finish
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.
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.
Leave it or put it right?
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 North Woolwich, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Avoid caulk in bathrooms and kitchens
- Don’t slide heavy items over sealed joints
- Ask before painting over a sealed joint
- Look at floor joints each spring
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up before they spread.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen and are harder to clean out.
