- Open joints around bathroom floor edges
- Open gaps along the bottom of skirting boards
- Gaps at thresholds between rooms
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Look at floor joints each spring
- Use furniture pads near skirting
- Keep floor cleaning water to a minimum at the edges
- Mark off resealed joints in warehouses
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact.
Floor joint sealing for homes and businesses in Barnes
We seal floor joints in homes, offices and commercial buildings across Barnes. Each job starts with looking at the floor and the gap, since that decides which sealant suits. We work on skirting boards, tiled floors and concrete floor joints, and people most often call us about tiled floors with no room to move and skirting that has pulled away from the floor.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover, in Barnes and beyond.
There’s a 12-month guarantee on every job.

What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- Subfloor problems that need a flooring contractor
- Tiles that have lifted or broken
- Leaks from a failed tanking system

What floor joint sealing looks like in Barnes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
As a London address, Barnes can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as St Osmund's Catholic Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a morning or an afternoon for most homes, depending on the size of the job. In Barnes, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- The sealant goes in, chosen for the floor and coloured to suit it.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
How to prepare
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Mention if the joints have been sealed before

What we are called out for in Barnes
Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack, and the sealant or grout breaks.
The problems people usually mention when they call are:
- Worn sealant at door thresholds
- Floor edges that trap water and grime
- Skirting caulk that keeps splitting
- Perimeter joints in tiled floors filled with grout
For landlords with property near Barnes Bridge station, gaps at skirtings and thresholds are worth sealing between tenancies.

What the job involves on each surface
Wet room and bathroom floors
Floor joints in bathrooms take water every day. They’re sealed with a flexible, anti-fungal silicone that keeps water out.
Thresholds
Two different floors meeting at a threshold move differently. We bridge them with a flexible bead.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Common questions in Barnes
Can you help a landlord with a rental near Barnes Bridge station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can you do floor joint sealing in Barnes?
Yes. We work across London and the South East, and Barnes is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear quote.
My floor grout keeps cracking in a line. Can you help?
Generally, yes. A crack along a grout line often means the floor needs room to move. We rake out that line and seal it with flexible sealant.
Can you use decorators’ caulk instead?
Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before any work starts.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
