How we handle floor joint sealing in North Harrow
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. If you are dealing with gaps at thresholds between rooms and cracked grout where a tiled floor needs a movement joint, we can help, on skirting boards, thresholds and commercial floors alike.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement.
Big or small, you get the same one-year guarantee in North Harrow and across Greater London.

Your questions about floor joint sealing in North Harrow
I let a flat near Harrow-on-the-Hill station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Is parking a problem for a job in North Harrow?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you cover North Harrow?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
When can I walk on the floor?
We’ll tell you before we leave. It depends on the sealant, and walking on it generally comes before mopping or wheeled traffic.
Why has a gap opened under my skirting?
Usually it’s movement: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible bead keeps up with the movement.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What we’re called out for in North Harrow
Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting and they change again in summer.
Any of these means the joints need attention:
- Failed joint filler in concrete floors
- Grout cracking in a straight line across a floor
- Perimeter joints in tiled floors filled with grout
- Floor edges that trap water and grime
Community buildings like Church of St Alban are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.
What your quote should include
- What product goes in the joint
- How much experience the applicator has
- Whether VAT is included

When something else is needed
A few problems are outside what sealant work can do:
- Bouncy or failing floorboards
- Structural movement or subsidence
- Loose, hollow or cracked tiles, which need a tiler
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Skirting boards
- Concrete floor joints
- Thresholds
- Tiled floors
- Commercial floors
- Wet room & bathroom floors
Why deal with it now?
Putting new grout into a crack that keeps reappearing doesn’t last. The movement is still there, so the grout fails again. Replacing that line with flexible sealant gives it somewhere to go. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in North Harrow, the repair is bigger than the sealant job would have been.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Why book with us
- Quality sealants from Arbo and Everbuild
- One-year guarantee on every job
- Domestic, commercial and hotel work
- Anti-fungal sanitary silicone in wet areas

What happens on the day

The work normally takes a few hours for most rooms, longer for large commercial floors, depending on how much there is to do. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- We clean and dry the edges of the joint.
- We apply a flexible sealant suited to the floor and tooled.
- Finally, we check the work and talk you through aftercare.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can

Joints and finishes in North Harrow homes
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. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
Managing a site like Longfield Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. Letting a property close to Harrow-on-the-Hill station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant.

How the job changes by surface
Wet room and bathroom floors
Bathroom floors meet baths, trays, panels and skirting. They’re sealed with a flexible, anti-fungal silicone to keep water out of the edges.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and stops debris collecting.
