How we handle floor joint sealing in Greenhithe
Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on tiled floors, wet room & bathroom floors and commercial floors, and the jobs we see most are tiled floors with no room to move and gaps opening between the floor and skirting.
For a new home in or near Greenhithe, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
We stand behind the work with a 12-month guarantee.

How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on the length of joint. For a job in Greenhithe, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the floor type, the gap and the traffic are checked.
- 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.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work

Advice
Greenhithe: your questions answered
Do you cover Greenhithe for floor joint sealing?
Yes, Greenhithe is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is Greenhithe within the area you cover?
Yes. Greenhithe is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
My floor grout keeps cracking in a line. Can you help?
Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant coloured to suit. If tiles are loose, that needs fixing first.
Is caulk good enough for skirting?
Caulk cannot cope with movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Do you work on commercial floors?
Yes, including warehouses, units, shops and offices. Work can be planned around your hours.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Why has a gap opened under my skirting?
Floors shrink and settle, especially in the first year or two and through the heating season. Rigid fillers split, so we use a flexible sealant.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why act early in Greenhithe
Not every floor joint takes the same sealant: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. Around Greenhithe, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas

What the job involves on each surface
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. We reseal them with a floor-joint product suited to the traffic.
Wet room and bathroom floors
Wet room floors rely on sound joints at the walls. We reseal it with a flexible silicone suited to wet areas and we will say if the problem looks like more than the joint.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Subfloor problems that need a flooring contractor
- Loose, hollow or cracked tiles, which need a tiler
- Large cracks that need a surveyor
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

Work for landlords, hotels and businesses
If you manage several properties in or around Greenhithe, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Floor joint sealing in Greenhithe: local notes
Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That’s why the skirting and threshold joints need a flexible seal.
Community buildings like Church of St Mary are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Schools such as Knockhall Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic.
