Joints and finishes in Southfields homes
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
As a London address, Southfields can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For buildings such as St John the Divine, joints in its floors, skirtings and thresholds need resealing as they wear.

Floor joint sealing in Southfields
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant coloured to suit the grout. We work on tiled floors, concrete floor joints and thresholds, and people most often call us about gaps opening between the floor and skirting and grout cracking in a straight line across a floor.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover, in Southfields and beyond.
Our work is backed for twelve months, in Southfields and everywhere else we cover.

What we’re called out for in Southfields
Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack.
The most common problems we see are:
- Concrete floor joints that have broken down
- Gaps between floors and kitchen plinths
- Grout used at the floor edge instead of sealant
- Tiled floors with no room to move
For site and facilities teams at buildings such as Floreat Wandsworth Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
Questions to ask before booking
- Whether all the old sealant comes out first
- How the joint is cleaned and prepared
- What product goes in the joint
- How the colour is chosen

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Questions from Southfields
Is parking an issue for floor joint sealing in Southfields?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you work for landlords with property near Earlsfield station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Why does the gap under my skirting keep coming back?
Floors shrink and settle, especially in the first year or two and through the heating season pulls the skirting and floor apart. Rigid fillers split, so we use a flexible sealant.
Are you insured?
Yes, we are fully insured.
Can sealant along the skirting be painted?
For painted skirting, we use a flexible product that can be painted. Silicone is not made to be painted, so we use it where the joint stays unpainted.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
What affects the quote in Southfields
We quote each job individually. This is what makes a difference:
- How much there is to do
- How many rooms, windows or areas are involved
- Access and height
- Any mould that needs treating
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Helping us quote
To make quoting easier, please include:
- The address or postcode of the job
- Any previous sealing or DIY work
- The rough size of the job
- Photos by email, if that’s easy
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.
Landlords, agents and businesses in Southfields
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Different surfaces, different methods
Tiled floors
When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it where it suits the floor.
Skirting boards
Skirting gaps are one of the most common floor joints we seal. The old caulk is removed first so the bead sits on a clean surface.
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most rooms, longer for large commercial floors. In Southfields, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor.
- Finally, we check the work and talk you through aftercare.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
How to get a quote
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

How to look after the new joints
So the new joints stay in good condition:
- Mark off resealed joints in warehouses
- Have a cracking tiled floor checked before tiles break
- Use furniture pads near skirting
- Do not fill floor joints with caulk where they move or get wet
Follow the cure time before walking on or cleaning the joint. Light foot traffic is usually fine sooner than wet cleaning or wheels, and we will tell you both.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen and are harder to clean out.
