About our floor joint sealing in Radlett
Where skirting is painted, we can use a flexible sealant that takes paint. For bathrooms and kitchens, silicone is normally the better choice because it handles water. Typical jobs include floor edges that trap water and grime and open gaps along the bottom of skirting boards, on concrete floor joints, skirting boards and wet room & bathroom floors.
For a new home in or near Radlett, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Every job comes with our one-year guarantee.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What happens if it’s left?
Floor joints left open collect dirt that’s hard to clean out, and they look untidy. Sealed joints are easier to keep clean and finishes the floor. Around Radlett, 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.
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Do not paint over silicone
- Mark off resealed joints in warehouses
- Vacuum floor joints regularly to stop grit building up
- Walk round the room once a year and look at the edges
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier and stops it getting worse.
How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on the length of joint. In a smaller place like Radlett, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at the gap and the floor type and agree the right sealant.
- Old caulk, grout or sealant is removed from the joint.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Before we arrive
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Advice
Floor joint sealing around Radlett
Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
For buildings such as St John, joints in its floors, skirtings and thresholds need resealing as they wear. If you let a flat or house near Radlett station, gaps at skirtings and thresholds are worth sealing between tenancies.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

When to call us in Radlett
Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away.
The most common problems we see are:
- Floor edges that trap water and grime
- Failed seals where bathroom floors meet baths and panels
- Concrete floor joints that have broken down
- Gaps opening between the floor and skirting
If you look after a building such as St John's Church of England Infant and Nursery School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Common questions in Radlett
Can you help a landlord with a rental near Radlett station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Radlett?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How soon can the floor be mopped?
Follow the cure time we give you. Feet are generally fine first, then mopping, then heavy wheels.
Will I be able to paint over the new joint?
For painted skirting, we use a flexible product that can be painted. Silicone will not take paint, so we use it where the joint stays unpainted.
Can you add a movement joint to a tiled floor?
Often, yes. We replace the grout along a suitable line with flexible sealant. If tiles are loose, that needs fixing first.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
