Questions from Roundshaw
Can you do floor joint sealing in Roundshaw?
Yes. We work across London and the South East, and Roundshaw is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
I let a flat near Wallington station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
How long does floor joint sealing take?
It depends on the size of the job, but most jobs take a morning or an afternoon for most homes. We will tell you when we quote.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Floor joint sealing in Roundshaw, done properly
Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone, which is not made to be painted. If you’re dealing with threshold joints that have opened or worn and cracked grout where a tiled floor needs a movement joint, we can put it right, whatever the surface.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Big or small, it’s backed by our 12-month guarantee in Roundshaw and across Greater London.

Leave it or put it right?
Left open, concrete joints break down under traffic. A sealed joint supports the edges. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Roundshaw.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What else we do in Roundshaw
How the job changes by surface
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.
Thresholds
A threshold is where floors and frames meet. A flexible sealant suits both floor finishes.
Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- Subfloor problems that need a flooring contractor
- Water getting under the tiles from elsewhere
- Concrete repairs beyond the joint
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Where we work in Roundshaw
- Concrete floor joints
- Tiled floors
- Wet room & bathroom floors
- Thresholds
- Commercial floors
- Skirting boards
Looking after it afterwards
Aftercare is simple:
- Get cracks along tile grout lines looked at early
- Ask before painting over a sealed joint
- Lift furniture rather than dragging it across joints
- Avoid caulk in bathrooms and kitchens
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges.
When to call us in Roundshaw
Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting.
If you can see any of these, it’s time to have the joints looked at:
- Chipped and open joints in warehouse floors
- Skirting that has pulled away from the floor
- Worn sealant at door thresholds
- Floor edges that trap water and grime
If you let a flat or house near Wallington station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
Questions to ask before you book
- Whether all the old sealant comes out first
- What the cure time is
- What happens if the job turns out different
- Whether they’re fully insured
What floor joint sealing looks like in Roundshaw
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. 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.
For buildings such as St. Paul's, joints in its floors, skirtings and thresholds need resealing as they wear. If you look after a building such as Wallington Primary Academy, floor and threshold joints in busy corridors wear quickly and are best resealed early.

- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
