Common questions in Addington
Can parking be tricky for a visit in Addington?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you do floor joint sealing in Addington?
Yes. We work across London and the South East, and Addington is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you reseal concrete floor joints in an industrial unit?
Yes, from warehouses and units to offices and shops. Work can be planned around your hours with out-of-hours work where needed.
Do you seal floor joints in bathrooms and kitchens?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone.
Can sealant along the skirting be painted?
On joints you want to paint, yes. Silicone does not take paint so mention it when you get a quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Floor joint sealing for homes and businesses in Addington
Concrete floors in warehouses and units have joints that take heavy wear. We reseal them with a product chosen for the movement and the traffic. We are often asked to deal with tiled floors with no room to move and open joints that fill with dirt, across skirting boards, wet room & bathroom floors and commercial floors.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
All of our work is guaranteed for twelve months.

Surface by surface
Commercial floors
Floor joint work in businesses can be planned around your hours. We can arrange out-of-hours work where it’s needed.
Tiled floors
Tiled floors need movement joints at edges and across large areas. Where needed, a line of grout is replaced with flexible sealant in a matching colour.
What happens if it’s left?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant stretches instead, so the joint stays closed. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Addington, the repair is bigger than a sealant job.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Keep dirt out of the joints
- Keep heavy wheels off new concrete joints until cured
- Do not slide heavy items over sealed joints
- Keep caulk for dry, still joints only
Silicone sealant is not made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen.

What we need to know
There’s no need for technical detail. It helps if you can tell us:

The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes a few hours for most rooms, longer for large commercial floors. In a London area like Addington, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- 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.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What floor joint sealing looks like in Addington
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. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
Managing a site like Applegarth Academy? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. As a London address, Addington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near West Wickham station, a tidy floor and skirting joint helps a rental look ready for the next tenant.
