St Albans Floor Joint Sealing
Our applicators work in St Albans on sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old sealant removed completely, joints prepared properly.
- Gaps at thresholds between rooms
- Floor edges that trap water and grime
- Cracked grout where a tiled floor needs a movement joint
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep dirt out of the joints
- Don’t paint over silicone
- Don’t fill floor joints with caulk where they move or get wet
- Keep floor cleaning water to a minimum at the edges
Don’t paint over silicone. If you plan to paint, we’ll use a paintable product.
Once concrete joint edges start to break, wheels make it worse. Early resealing helps keep the joint intact and the floor safer.
How we handle floor joint sealing in St Albans
Thresholds are where two floors, or a floor and a door, meet. We seal them with a flexible sealant suited to the floor finishes either side in a colour to suit. We work on commercial floors, wet room & bathroom floors and skirting boards, and the jobs we see most are skirting caulk that keeps splitting and threshold joints that have opened or worn.
Commercial units around a large town like St Albans generally have concrete floors with joints that need filling and resealing as they wear. At home, it’s the same idea on a smaller scale: skirtings, thresholds and shower seals.
All our work comes with a one-year guarantee, wherever you are in Hertfordshire.

New homes and floors in St Albans
Across Hertfordshire, 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. That’s why the skirting and threshold joints need a flexible seal.
If you let a flat or house near St Albans station, gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as Loreto College are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Do you need floor joint sealing in St Albans?
When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, showing where a movement joint was needed.
The most common problems we see are:
- Threshold joints that have opened or worn
- Caulk that has cracked where the floor moves
- Gaps between floors and kitchen plinths
- Cracked grout where a tiled floor needs a movement joint
If you look after a church, hall or community building such as Church of St. Peter, joints in its floors, skirtings and thresholds need resealing as they wear.

Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for most rooms, longer for large commercial floors. For homes and businesses in busier parts of St Albans, parking needs a little planning. For flats, mention stairs, lifts and shared entrances as well.
- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor and smooth it.
- Finally, we check the work and talk you through aftercare.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
