Floor joint sealing for homes and businesses in Pentonville
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. Each is resealed with a floor-joint product suited to what runs over it. If you have caulk that has cracked where the floor moves and worn sealant at door thresholds, we can help.
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, in Pentonville and beyond.
Big or small, it’s backed by our 12-month guarantee in Pentonville and across Greater London.

How the job changes by surface
Thresholds
Thresholds take daily traffic, so we choose a hard-wearing, flexible product and neatly finished.
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. Where water is involved, silicone is the better choice.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on the length of joint and we leave things clean and tidy. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Pentonville. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
How to prepare
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

Related advice
Can I do it myself?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Signs you need floor joint sealing in Pentonville
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.
Keep an eye out for these signs:
- Open joints that fill with dirt
- Skirting that has pulled away from the floor
- Skirting caulk that keeps splitting
- Rigid edge joints in tiled floors
As a London address, Pentonville can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- Whether all the old sealant comes out first
- What guarantee comes with the work
- Are they insured?
- Is VAT in the price?
Why deal with it now?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant moves with the floor, so the joint stays closed. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Pentonville.
A few things move the cost up or down: 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.
What you get with us
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
- Neat joints and a tidy finish
- Full insurance on every job

Common questions in Pentonville
Can you help a landlord with a rental near Essex Road station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Do you cover Pentonville for floor joint sealing?
Yes. Our work covers London and the South East, and Pentonville is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Is caulk good enough for skirting?
Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you use a paintable sealant?
If you tell us beforehand, yes. We use a paintable flexible sealant on joints you plan to paint and wet areas get silicone.
Floor joint sealing around Pentonville
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not 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.
If you let a flat or house near Essex Road station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a church, hall or community building such as Church of Saint Peter, joints in its floors, skirtings and thresholds need resealing as they wear.
