About floor joint sealing in City of London
Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints using a product that suits the floor. We work on concrete floor joints, skirting boards and commercial floors, and people most often call us about gaps opening between the floor and skirting and gaps between floors and kitchen plinths.
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work generally takes a morning or an afternoon for most homes.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- We apply a flexible sealant suited to the floor.
- We check the joints and explain the aftercare.
What you’ll pay
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Any old sealant cut out fully, not covered over
- Trusted Arbo and Everbuild sealants
- Full insurance on every job

Floor joint sealing across City of London: local notes
Across City of London, from City of London outwards, new homes go up alongside older streets. Snagging in new homes and floor joints in older ones are both part of the work.
The South East is one of the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across City of London is planned around the weather.
City of London: For buildings such as St Olave Old Jewry, joints in its floors, skirtings and thresholds need resealing as they wear. For site and facilities teams at buildings such as Fashion Retail Academy, entrance and corridor floor joints take a lot of traffic.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Lift furniture rather than dragging it across joints
- Get cracks along tile grout lines looked at early
- Check skirting joints after the heating season
- Check the sealant is paintable before decorating
Lift furniture rather than sliding it over sealed joints. Sharp edges can cut the sealant especially in the first few days.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.
Why it fails
Caulk is the usual filler for skirting. It cracks where there’s movement or water so the gap reappears.
Signs it’s time to call us include:
- Perimeter joints in tiled floors filled with grout
- Open joints around bathroom floor edges
- Worn sealant at door thresholds
- Open gaps along the bottom of skirting boards
Landlords, agents and businesses in City of London
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Leave it or put it right?
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges and keeps the damage down.
What your quote should include
- Which colour the sealant will be
- How long to leave it before use
- The length of the guarantee
- What happens if the job turns out different
Questions from City of London
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Can you add a movement joint to a tiled floor?
Normally, yes. Straight cracks in grout often show where a movement joint was needed. We replace that grout with a flexible joint.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
