Floor & skirting joints in Catherington, Hampshire
Professional floor joint sealing in and around Catherington, with old sealant always removed completely and a 12-month guarantee.
- Open gaps along the bottom of skirting boards
- Worn sealant at door thresholds
- Cracked caulk along skirting in bathrooms and kitchens
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Floor joint sealing for homes and businesses in Catherington
Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant. We work on concrete floor joints, thresholds and commercial floors, and the jobs we see most are grout used at the floor edge instead of sealant and failed joint filler in concrete floors.
Somewhere as small as Catherington, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
There’s a 12-month guarantee on every job.

FAQs for Catherington
Do you cover Catherington for floor joint sealing?
Yes. We work across London and the South East, and Catherington is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
I let a flat near Rowlands Castle station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
My floor grout keeps cracking in a line. Can you help?
In many cases, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant coloured to suit. Loose or cracked tiles need a tiler first.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Why has a gap opened under my skirting?
Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.
How soon can the floor be mopped?
That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over so there’s no guesswork.
Honest limits
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Tiles that have lifted or broken
- Damaged concrete that needs breaking out and repairing
- Leaks from a failed tanking system
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.
What we seal

What we’re called out for in Catherington
Caulk is the usual filler for skirting. It cracks where there’s movement or water so the gap reappears.
These are the problems we’re asked about most:
- Grout cracking in a straight line across a floor
- Cracked caulk along skirting in bathrooms and kitchens
- Dirt and water collecting in open floor joints
- Perimeter joints in tiled floors filled with grout
Letting a property close to Rowlands Castle station? Then gaps at skirtings and thresholds are worth sealing between tenancies.
What to look for in a quote

- What preparation is included
- What insurance they hold
- Whether VAT is included
Why deal with it now?
Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. Around Catherington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- 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.
Before we arrive

Advice
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask before painting over a sealed joint
- Sweep along the edges of the floor
- Do not slide heavy items over sealed joints
- Keep heavy wheels off new concrete joints until cured
Check the joints after the first winter. If anything has opened, it’s easy to reseal.
A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.
Joints and finishes in Catherington homes
Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
Schools such as Catherington Church of England Infant School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. If you look after a church, hall or community building such as Church of All Saints, joints in its floors, skirtings and thresholds need resealing as they wear.
