Different surfaces, different methods
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. We rake out any grout there and reseal.
Concrete floor joints
We clean concrete joints out thoroughly before sealing first. Backing goes in where the depth needs controlling.
Floor joint sealing for homes and businesses in Chiswick
Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. We’re often asked to deal with open joints around bathroom floor edges and floor edges that trap water and grime, on concrete floor joints, wet room & bathroom floors and commercial floors.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Chiswick and beyond.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What else we do in Chiswick
What happens if it’s left?
Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. In a flat in Chiswick, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

Common questions in Chiswick
I let a flat near Chiswick station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Can you do floor joint sealing in Chiswick?
Yes. We work across London and the South East, and Chiswick is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
How soon can the floor be mopped?
You will get the times before we go. It depends on the sealant, and walking on it normally comes before mopping or wheeled traffic.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Why not just use caulk?
Caulk works on still, dry joints, but it splits where the joint moves or gets wet. For most floor joints, we use a flexible sealant.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
When to call us in Chiswick
Water and dirt collect in open floor joints. In kitchens and bathrooms, mop water gets into the gap and behind skirting and plinths.
Most people get in touch when they notice one of these:
- Grout cracking in a straight line across a floor
- Failed seals where bathroom floors meet baths and panels
- Chipped and open joints in warehouse floors
- Rigid edge joints in tiled floors
For site and facilities teams at buildings such as The William Hogarth Primary School, entrance and corridor floor joints take a lot of traffic.

How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most rooms, longer for large commercial floors. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Chiswick. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we check the joint and the floor and agree which sealant suits it.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
How to prepare
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Mention any parking rules near the property
How to get a quote
Every job is quoted individually. Just ring 0345 464 0079 or send us an email with the details and send pictures if you have them.

What affects the cost of floor joint sealing
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms or windows
- The product the joint needs
- Any mould that needs treating
- Any working-time requirements on site
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Asking for a quote
When you call or email, these details help:
- Where the property is
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Floor joint sealing around Chiswick
Much of London’s new housing is flats in larger 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 they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.
For landlords with property near Chiswick station, gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a church, hall or community building such as St. Nicholas Church, joints in its floors, skirtings and thresholds need resealing as they wear.
