Your questions about floor joint sealing in West Green
Is parking a problem for a job in West Green?
Parking in West Green, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Seven Sisters station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Why not just use caulk?
Because caulk cracks where there’s movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
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.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Why has a gap opened under my skirting?
Normally it’s movement: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible sealant stays closed as the floor moves.
How we handle floor joint sealing in West Green
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. We work on thresholds, skirting boards and tiled floors, and the jobs we see most are gaps at thresholds between rooms and failed seals where bathroom floors meet baths and panels.
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.
Each job carries a 12-month guarantee, large or small.

Why deal with it now?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, but the movement soon cracks it. A flexible sealant stretches instead, so the joint stays closed. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Common problems we fix in West Green
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. You’ll see a crack running along the grout, where a flexible joint should have been.
These are the problems we are asked about most:
- Failed seals where bathroom floors meet baths and panels
- Rigid edge joints in tiled floors
- Concrete floor joints that have broken down
- Floor edges that trap water and grime
Community buildings like St Philip the Apostle are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What to tell us for a quote
When you call or email, it’s useful to know:
- What’s wrong with the joints now
- Whether it’s a home or a business
- How we’d reach the joints
- Photos by email, if that is easy
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is usually better.

What floor joint sealing looks like in West Green
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 each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.
If you look after a building such as West Green Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. West Green is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What happens on the day
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most rooms, longer for large commercial floors. In a London area like West Green, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- 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.
- The joint is tooled neatly and the cure time explained.
Preparing for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
