How it 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 morning or an afternoon for most homes. In a small place like South Darenth, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- We take out any old caulk, sealant or grout along the line.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- The sealant goes in, chosen for the floor and coloured to suit it.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
How to prepare
- On commercial sites, let us know about site rules
- Mention any tricky access
- Clear items away from the joints we’re working on

About our floor joint sealing in South Darenth
The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk normally cracks where there’s movement, so we use a flexible sealant that moves with the floor. We work on skirting boards, tiled floors and commercial floors, and the jobs we see most are skirting caulk that keeps splitting and concrete floor joints that have broken down.
Work in a small place like South Darenth just needs the journey and access planning, and the work itself is the same as on any site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the quote in South Darenth
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Access and height
- Any mould that needs treating
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- The problem you’ve noticed
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Use a well-wrung mop rather than flooding the floor
- Do not fill floor joints with caulk where they move or get wet
- Keep dirt out of the joints
- Mark off resealed joints in warehouses
Do not paint over silicone. 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 over time.
Common questions in South Darenth
Do you cover South Darenth for floor joint sealing?
Yes. We work across London and the South East, and South Darenth is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
I let a flat near Farningham Road station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Why not just use caulk?
Caulk can’t cope with movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Can you seal where the floor meets the bath panel?
Yes. The old joint comes out and a flexible silicone replaces it.
Do you have insurance?
Yes. We are fully insured for every job we do.
What do you need from me for a quote?
Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
My floor grout keeps cracking in a line. Can you help?
In many cases, yes. We replace the grout along a suitable line with flexible sealant. If tiles are loose, that needs fixing first.
How long does the job take?
Typically it takes a few hours, depending on the length of joint. Bigger jobs take longer, and we’ll say how long yours will take.
Joints and finishes in South Darenth homes
Across Kent, 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.

Schools such as Horton Kirby Church of England Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

What we are called out for in South Darenth
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, where a flexible joint should have been.
Common reasons people contact us include:
- Rigid edge joints in tiled floors
- Open joints around bathroom floor edges
- Cracked grout where a tiled floor needs a movement joint
- Worn sealant at door thresholds
Community buildings like The Parish Church of Saint Mary are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Leave it or put it right?
Dirt builds up in open joints and makes the floor look worn. Sealed joints are easier to keep clean. Where a wall is exposed, as many are in small places like South Darenth, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

How the job changes by surface
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it where it suits the floor.
Concrete floor joints
We clean concrete joints out thoroughly before sealing first. We fit backing where needed.
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
