DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Floor joint sealing in Earlsfield
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out so water and dirt cannot get in. We work on wet room & bathroom floors, skirting boards and concrete floor joints, and the jobs we see most are open joints that fill with dirt and gaps between floors and kitchen plinths.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Earlsfield and beyond.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most rooms, longer for large commercial floors from start to finish. In Earlsfield, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, the floor type, the gap and the traffic are checked.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Surface by surface
Concrete floor joints
Old filler, dust and debris are cleaned out of the joint. We fit backing where needed.
Skirting boards
Skirting-to-floor joints are a regular job for us. We take out any cracked caulk before sealing so the new sealant bonds.
What we’re called out for in Earlsfield
Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and can reach the subfloor.
Look out for any of the following:
- Open gaps along the bottom of skirting boards
- Threshold joints that have opened or worn
- Failed joint filler in concrete floors
- Gaps between floors and kitchen plinths
For buildings such as St John the Divine, floor and skirting joints in halls and kitchens wear like any others.
Before you book anyone
- What product goes in the joint
- How much experience the applicator has
- How the colour is chosen
- Whether VAT is included
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Use furniture pads near skirting
- Look at floor joints each spring
- Mark off resealed joints in warehouses
- Ask before painting over a sealed joint
Silicone sealant is not made to take paint. If you plan to paint, we will use a paintable product.
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.
What happens if it’s left?
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Common questions in Earlsfield
Is Earlsfield in your area for floor joint sealing?
Yes, Earlsfield is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Can parking be tricky for a visit in Earlsfield?
Parking in Earlsfield, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
What do you need from me for a quote?
Tell us what needs doing and where, plus pictures if you have them. If we need more, we will ask.
Is caulk good enough for skirting?
Caulk is fine for dry joints that don’t move, but it splits where the joint moves or gets wet. For most floor joints, we use a flexible sealant.
Do you work on commercial floors?
Yes, including warehouses, units, shops and offices. We can plan around your opening times with out-of-hours work where needed.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Where do you work from?
Mr Mastic is based in Crawley. We cover Earlsfield and the rest of Greater London.
How long does floor joint sealing take?
A typical job takes a few hours, depending on the length of joint. We’ll confirm how long when we quote.
