Floor joint sealing in St Mary's, done properly
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. If you’re dealing with skirting caulk that keeps splitting and gaps opening between the floor and skirting, we can help, whatever the surface.
Homes around St Mary's range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
There’s a 12-month guarantee on every job, whatever its size.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on the length of joint. In a smaller place like St Mary's, 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.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- 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.
Before we arrive
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep dirt out of the joints
- Keep heavy wheels off new concrete joints until cured
- Look at floor joints each spring
- Use a well-wrung mop rather than flooding the floor
Check the joints after the first winter. Small gaps at the ends can be touched up early on.
Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact and the floor safer.

Common questions in St Mary's
Will you come out to St Mary's?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is St Mary's in your area for floor joint sealing?
Yes, St Mary's is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can sealant along the skirting be painted?
If you tell us beforehand, yes. We use a paintable flexible sealant on joints you plan to paint.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
Why not just use caulk?
Because caulk cracks where there’s movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
What happens if it’s left?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. Homes in smaller places like St Mary's can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
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. Your quote takes all of that into account.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What floor joint sealing looks like in St Mary's
Across Southampton, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
For site and facilities teams at buildings such as Hope Community School Southampton, floor and threshold joints in busy corridors wear quickly and are best resealed early. For buildings such as St Mary's Church, joints in its floors, skirtings and thresholds need resealing as they wear.
