About our floor joint sealing in Leatherhead
Concrete floors in warehouses and units have joints that take heavy wear. We reseal them with a product chosen for the movement and the traffic. We work on tiled floors, concrete floor joints and commercial floors, and common reasons people get in touch are gaps between floors and kitchen plinths and failed joint filler in concrete floors.
Homes around Leatherhead move a little with the seasons, and skirting and floor joints show it first. A flexible sealant, rather than rigid filler, keeps those joints closed.
Each job carries a 12-month guarantee, whatever its size.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Have a cracking tiled floor checked before tiles break
- Do not slide heavy items over sealed joints
- Check the sealant is paintable before decorating
- Walk round the room once a year and look at the edges
Follow the cure time before walking on or cleaning the joint. Light foot traffic is generally fine sooner than wet cleaning or wheels so we will give you each time.
Small gaps are quick to seal. Left alone, they collect dirt and widen.
Should I try it myself 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, then guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for most rooms, longer for large commercial floors in most cases. In Leatherhead, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- 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.
- A flexible sealant suited to the floor is applied and smooth it.
- Finally, we check the work and talk you through aftercare.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Are you fully insured?
Yes. Mr Mastic is fully insured.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Why act early in Leatherhead
Floor joints left open collect dirt that is hard to clean out. A neat sealed joint is easier to clean and look tidier. In Leatherhead, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Signs you need floor joint sealing in Leatherhead
New floors settle once they’re in use. The edges pull away from the skirting and anything rigid cracks.
Keep an eye out for any of the following:
- Grout used at the floor edge instead of sealant
- Open gaps along the bottom of skirting boards
- Chipped and open joints in warehouse floors
- Cracked grout where a tiled floor needs a movement joint
If you let a flat or house near Leatherhead station, gaps at skirtings and thresholds are worth sealing between tenancies.

Floor joint sealing around Leatherhead
Floors around Surrey run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal.
For site and facilities teams at buildings such as Leatherhead Trinity School and Children's Centre, entrance and corridor floor joints take a lot of traffic. If you look after a church, hall or community building such as Church of Our Lady and St Peter, joints in its floors, skirtings and thresholds need resealing as they wear.
