Floor joint sealing in Letchworth Garden City
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant coloured to suit the grout. Typical jobs include tiled floors with no room to move and gaps opening between the floor and skirting, across concrete floor joints, tiled floors and skirting boards.
Towns like Letchworth Garden City have older streets and newer estates side by side. In a newer home, sealant and floor joints are generally among the first things to need attention.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Your questions about floor joint sealing in Letchworth Garden City
What guarantee comes with floor joint sealing in Letchworth Garden City?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you work for landlords with property near Letchworth Garden City station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
How long does the job take?
A typical job takes a few hours, depending on the length of joint, including the preparation. We will confirm how long when we quote.
Why does the gap under my skirting keep coming back?
Normally it’s movement: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible bead keeps up with the movement.
Can sealant along the skirting be painted?
If you tell us beforehand, yes. Joints that will be painted get a paintable product.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

What else we do in Letchworth Garden City
Why deal with it now?
Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. A flexible movement joint is the fix. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Letchworth Garden City they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
What you pay reflects the work, not guesswork. That is why we ask about the job first.

Advice
Landlords, agents and businesses in Letchworth Garden City
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What affects the cost of floor joint sealing
The price is agreed before any work begins. It’s based on:
- The product the joint needs
- Any working-time requirements on site
- Whether there’s mould to deal with
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
To help us quote quickly, please include:
- The rough size of the job
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- What’s wrong with the joints now
To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Large cracks that need a surveyor
- Failed waterproofing under a wet room floor
- Cracked or broken concrete slabs
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Floor joint sealing in Letchworth Garden City: local notes
Letchworth Garden City is one of England’s garden cities, planned in the early twentieth century. Homes range from the original garden city houses to newer developments, so floor and skirting joints, and sealant in new homes, are all part of the work there. Across Hertfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
If you let a flat or house near Letchworth Garden City station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a church, hall or community building such as St Michael, joints in its floors, skirtings and thresholds need resealing as they wear.

When to call us in Letchworth Garden City
Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water, which is why so many skirting joints look broken.
Keep an eye out for these signs:
- Dirt and water collecting in open floor joints
- Gaps opening between the floor and skirting
- Open joints around bathroom floor edges
- Grout cracking in a straight line across a floor
If you look after a building such as Pixmore Junior School, entrance and corridor floor joints take a lot of traffic.
