Floor joint sealing for homes and businesses in Leamouth
We seal floor joints in homes, offices and commercial buildings across Leamouth. Each job starts with looking at the floor and the gap, because the right sealant depends on both. Common call-outs are for skirting caulk that keeps splitting and gaps opening between the floor and skirting, on tiled floors, commercial floors and wet room & bathroom floors.
Much of London’s new housing is flats 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.

Leamouth: your questions answered
Can you do floor joint sealing in Leamouth?
Yes. Our work covers London and the South East, and Leamouth is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Custom House station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you use a paintable sealant?
It depends on the sealant, so let us know first. Joints that will be painted get a paintable product and wet areas get silicone.
Do you work on commercial floors?
Yes, including warehouses, units, shops and offices. Work can be planned around your hours, and out-of-hours work can be arranged.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
My floor grout keeps cracking in a line. Can you help?
Often, yes. A crack along a grout line often means the floor needs room to move. We replace that grout with a flexible joint.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you offer different sealant colours?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before any work starts.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Structural movement or subsidence
- Water getting under the tiles from elsewhere
- A tiled floor that needs relaying
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Surfaces we seal
- Tiled floors
- Wet room & bathroom floors
- Thresholds
- Commercial floors
- Concrete floor joints
- Skirting boards
Common problems we fix in Leamouth
Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack, and the sealant or grout breaks.
Signs it’s time to call us include:
- Caulk that has cracked where the floor moves
- Gaps between floors and kitchen plinths
- Grout cracking in a straight line across a floor
- Worn sealant at door thresholds
Community buildings like Church of St Luke are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
Before booking anyone
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- How long the guarantee is
- Is VAT in the price?
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Vacuum floor joints regularly to stop grit building up
- Check skirting joints after the heating season
- Get cracks along tile grout lines looked at early
- Avoid sloshing water against skirting
Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal before they spread.
A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a morning or an afternoon for most homes. In a London area like Leamouth, 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.
- The joint is vacuumed clean and backing fitted where needed.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

How the job changes by surface
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. That line is converted to a flexible joint where it suits the floor.
Concrete floor joints
We clean concrete joints out thoroughly before sealing first. We fit backing where needed.
How we quote for floor joint sealing
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- How easy the joints are to reach
- The amount of work
- When we can work, for business premises
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
To make quoting easier, please include:
- Any access issues, like height or stairs
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
For a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before work begins.
Joints and finishes in Leamouth homes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. 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 is why the skirting and threshold joints need a flexible seal.
Leamouth is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as St Luke's Primary School, entrance and corridor floor joints take a lot of traffic.
