How we handle floor joint sealing in Finsbury
Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. We work on tiled floors, skirting boards and concrete floor joints, and common reasons people get in touch are skirting caulk that keeps splitting and open gaps along the bottom of skirting boards.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
All of our work is guaranteed for twelve months, in Finsbury and everywhere else we cover.

Keeping the joints in good condition
So the new joints stay in good condition:
- Avoid sloshing water against skirting
- Mark off resealed joints in warehouses
- Get cracks along tile grout lines looked at early
- Sweep along the edges of the floor
Check the joints after the first winter. If anything has opened, it’s easy to reseal.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
Floor joint sealing in Finsbury: local notes
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
For site and facilities teams at buildings such as Prior Weston Primary School and Children's Centre, floor and threshold joints in busy corridors wear quickly and are best resealed early. If you look after a church, hall or community building such as Jewin Welsh Presbyterian Chapel, floor and skirting joints in halls and kitchens wear like any others.

What affects the quote in Finsbury
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- The size of the job
- Whether the work is at height
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
When you contact us, it’s useful to know:
- The address or postcode of the job

- Photos by email, if that is easy
- The type of property

Finsbury questions
Is Finsbury in your area for floor joint sealing?
Yes, Finsbury is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Old Street station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
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 rake out that line and seal it with flexible sealant.
Do you use a paintable sealant?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone will not take paint, so we use it where the joint stays unpainted.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours, depending on the length of joint. We will tell you when we quote.
How long before the joint can take traffic?
It depends on the product and the conditions. We give you the times for walking, cleaning and traffic when we finish.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.

What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on the length of joint. In a London area like Finsbury, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor.
- Finally, we check the work and talk you through aftercare.
Before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Do you need floor joint sealing in Finsbury?
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. You’ll see a crack running along the grout, where a flexible joint should have been.
Signs it’s time to call us include:
- Grout used at the floor edge instead of sealant
- Gaps at thresholds between rooms
- Chipped and open joints in warehouse floors
- Tiled floors with no room to move
As a London address, Finsbury can be tricky for parking: let us know about parking bays, permits or a driveway.
What to look for in a quote
- Whether all the old sealant comes out first
- How the colour is chosen
- How much experience the applicator has
- When the joint can take water or movement
What happens if it’s left?
Left open, concrete joints break down under traffic. A sealed joint supports the edges and keeps the damage down. 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 Finsbury, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why Finsbury customers choose us
- We never seal over old sealant
