Floor joint sealing in Underling Green, done properly
Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone. We work on skirting boards, tiled floors and wet room & bathroom floors, and people most often call us about floor edges that trap water and grime and gaps between floors and kitchen plinths.
Somewhere as small as Underling Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Your job is guaranteed for a year, as with all our work.

What affects the cost of floor joint sealing
We don’t publish a price list, because jobs vary so much. What we look at:
- When we can work, for business premises
- The old material and how stubborn it is
- Mould in or behind the old joints
- The type of sealant required
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Helping us quote
There’s no need for technical detail. Just tell us:
- Pictures of the joints, sent by email
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job and send pictures if you have them.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Walk round the room once a year and look at the edges
- Use furniture pads near skirting
- Ask before painting over a sealed joint
- Sweep along the edges of the floor
Follow the cure time before walking on or cleaning the joint. Light foot traffic is normally fine sooner than wet cleaning or wheels so we’ll give you each time.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier and the edges sound.
Underling Green: your questions answered
Do you cover smaller places like Underling Green?
Yes. Underling Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Underling Green for floor joint sealing?
Yes. Our work covers London and the South East, and Underling Green is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you work on commercial floors?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Let us know about the traffic.
How long does the job take?
A typical job takes a few hours for most rooms, longer for large commercial floors, including the preparation. Your quote will say how long we expect yours to take.
Can you add a movement joint to a tiled floor?
Generally, 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 use a paintable sealant?
On joints you want to paint, yes. Silicone doesn’t take paint, so tell us your plans.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a morning or an afternoon for most homes. In a small place like Underling Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- The joint is tooled neatly and the cure time explained.
How to prepare
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Floor joint sealing in Underling Green: local notes
Across Kent, 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’s why the skirting and threshold joints need a flexible seal.
Around Underling Green, as everywhere, floor joint sealing is only as good as the preparation behind it.
Underling Green is about 5 miles south of Maidstone, in Kent. Jobs in Underling Green get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 922 towns and villages across Kent. We also work in Crawley, about 31 miles from Underling Green.

What happens if it’s left?
An open concrete floor joint gets wider every time something heavy crosses it. Resealing it early protects the edges and keeps the damage down. Around Underling Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Common problems we fix in Underling Green
Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting, then close again in damper months.
The most common problems we see are:
- Gaps opening between the floor and skirting
- Failed seals where bathroom floors meet baths and panels
- Floor edges that trap water and grime
- Skirting caulk that keeps splitting
For landlords with property near Marden station, a tidy floor and skirting joint helps a rental look ready for the next tenant.
