How we handle floor joint sealing in Newington
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. If you’re dealing with worn sealant at door thresholds and dirt and water collecting in open floor joints, we can put it right, on skirting boards, thresholds and commercial floors alike.
Older homes in small places like Newington often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job is covered by a one-year guarantee, wherever you are in Kent.

Common questions in Newington
Do you cover smaller places like Newington?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Folkestone West station. Can you help?
Yes, landlords and agents are among the people we work for. 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.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
My floor grout keeps cracking in a line. Can you help?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant so the floor can move.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you seal floor joints in bathrooms and kitchens?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so we seal them with silicone suited to wet areas.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours for most rooms, longer for large commercial floors. We’ll tell you when we quote.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most rooms, longer for large commercial floors. Somewhere like Newington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and tooled.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
What sealant work can’t fix
It helps to know what we cannot do too:
- Loose, hollow or cracked tiles, which need a tiler
- Floors that are uneven or need levelling
- Leaks from a failed tanking system
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Why it’s worth doing now in Newington
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. Where a wall is exposed, as many are in small places like Newington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

Joints and finishes in Newington 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’s why the skirting and threshold joints need a flexible seal.
Rented homes near Folkestone West station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. Community buildings like Church of St Nicholas are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

- Whether old sealant or filler has to be cut out
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Roughly how big the job is
- Any previous sealing or DIY work
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep dirt out of the joints
- Do not slide heavy items over sealed joints
- Ask before painting over a sealed joint
- Mark off resealed joints in warehouses
Silicone sealant is not made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
