How we handle floor joint sealing in St Luke's
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. We work on thresholds, tiled floors and wet room & bathroom floors, and people most often call us about skirting caulk that keeps splitting and threshold joints that have opened or worn.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in St Luke's and beyond.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Lift furniture rather than dragging it across joints
- Keep heavy wheels off new concrete joints until cured
- Have a cracking tiled floor checked before tiles break
- Keep dirt out of the joints
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. Ignored, they fill with dirt and open further and are harder to clean out.
St Luke's questions
Is parking an issue for floor joint sealing in St Luke's?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you cover St Luke's for floor joint sealing?
Yes. We work across London and the South East, and St Luke's is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Can you do several jobs on one visit?
Yes. Just list everything you need.
How do I get a quote for floor joint sealing in St Luke's?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you seal warehouse floor joints?
Yes. We reseal concrete floor joints in commercial and industrial units. The product is chosen for the traffic the floor takes.
Different surfaces, different methods
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. Where water is involved, silicone is the better choice.
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
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.
When to call us in St Luke's
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting and anything rigid cracks.
These are the problems we’re asked about most:
- Chipped and open joints in warehouse floors
- Caulk that has cracked where the floor moves
- Tiled floors with no room to move
- Floor edges that trap water and grime
Letting a property close to Old Street station? Then gaps at skirtings and thresholds are worth sealing between tenancies.
What your quote should include
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- Whether they seal over old material or remove it
How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a morning or an afternoon for most homes. In St Luke's, 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.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
Getting 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 email pictures if that’s easy.
Related advice
What floor joint sealing looks like in St Luke's
Many of London’s new homes are flats in bigger 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. The joint at the skirting or threshold has to allow for that.
If you look after a church, hall or community building such as Jewin Welsh Presbyterian Chapel, joints in its floors, skirtings and thresholds need resealing as they wear. For site and facilities teams at buildings such as St Luke's CofE Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What else we do in St Luke's
Leave it or put it right?
Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In a flat in St Luke's, 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.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
