How we handle floor joint sealing in Upper Norwood
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’re dealing with gaps opening between the floor and skirting and open joints around bathroom floor edges, we can help, whatever the surface.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
A one-year guarantee comes with the work, just as it does everywhere we cover.

The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a morning or an afternoon for most homes, and the area is left clean. In Upper Norwood, 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.
- 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.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Tell us about any water getting in

How to look after the new joints
Aftercare is simple:
- Walk round the room once a year and look at the edges
- Avoid sloshing water against skirting
- Sweep along the edges of the floor
- Check the sealant is paintable before decorating
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed while it cures.
Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges.
How the job changes by surface
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. Where water is involved, silicone is the better choice.
Thresholds
Two different floors meeting at a threshold move differently. A flexible sealant bridges them.
Upper Norwood: your questions answered
Is parking an issue for floor joint sealing in Upper Norwood?
Parking in Upper Norwood, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Gipsy Hill station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Why not just use caulk?
Caulk cannot cope with movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours, depending on the length of joint. We will give you a better idea when we quote.
Where do you work from?
We work from Crawley. We cover Upper Norwood and the rest of Greater London, along with the rest of our area.
How long before the joint can take traffic?
That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over.

Why it’s worth doing now in Upper Norwood
Leaving skirting gaps until the next decorating job lets dirt and draughts in. It’s a quick job to seal them now. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Upper Norwood, the repair is bigger than the sealant job would have been.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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.
