How we handle floor joint sealing in Isle of Dogs
Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. Common call-outs are for tiled floors with no room to move and skirting that has pulled away from the floor, on thresholds, commercial floors and concrete floor joints.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Isle of Dogs as anywhere.
All our work is covered by a 12-month guarantee.

Isle of Dogs: your questions answered
Do you cover Isle of Dogs for floor joint sealing?
Yes. We work across London and the South East, and Isle of Dogs is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Can you help a landlord with a rental near Greenwich station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
How long will you be here?
As a guide, most jobs take a few hours for most rooms, longer for large commercial floors. Bigger jobs take longer.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Can you add a movement joint to a tiled floor?
Often, yes. We replace the grout along a suitable line with flexible sealant coloured to suit. If tiles are loose, that needs fixing first.
Do you seal floor joints in bathrooms and kitchens?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone, colour-matched where it shows.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
If you manage several properties in or around Isle of Dogs, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
What happens on the day
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours, depending on the length of joint. In Isle of Dogs, 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 looking at the floor, the gap and the traffic, then choose the product.
- Old caulk, grout or sealant is removed from the joint.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Why act early in Isle of Dogs
Dirt builds up in open joints. Sealed joints are easier to keep clean and finishes the floor. 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.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Floor joint sealing in Isle of Dogs: local notes
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
If you look after a church, hall or community building such as Church of St Nicholas, joints in its floors, skirtings and thresholds need resealing as they wear. Schools such as Harbinger Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic.

Surface by surface
Wet room and bathroom floors
Mop water gets into any open joint at the edge of a bathroom floor. A neat silicone joint keeps it out.
Thresholds
Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product and tool it flush.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Look at floor joints each spring
- Avoid sloshing water against skirting
- Sweep along the edges of the floor
- Use furniture pads near skirting
Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the surface smoother.

Can I do it myself?
If you’re 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 fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
