Floor & skirting joints in Broad Colney, Hertfordshire

Floor joint sealing in Broad Colney, done properly
Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we close it with a flexible sealant instead. We work on concrete floor joints, skirting boards and thresholds, and the jobs we see most are concrete floor joints that have broken down and dirt and water collecting in open floor joints.
Somewhere as small as Broad Colney, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You get a one-year guarantee, the same in Broad Colney as everywhere else we work.

How the job changes by surface
Thresholds
A threshold is where floors and frames meet. A flexible sealant suits both floor finishes.
Skirting boards
Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking in a colour to suit.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How the visit works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job generally takes a morning or an afternoon for most homes, and we tell you how long to leave it before we go. For a village or hamlet like Broad Colney, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises

Advice
What happens if it’s left?
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job. Older cottages and farmhouses around Broad Colney can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Do you need floor joint sealing in Broad Colney?
Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open.
It’s worth asking for a quote if you see:
- Floor edges that trap water and grime
- Chipped and open joints in warehouse floors
- Gaps between floors and kitchen plinths
- Threshold joints that have opened or worn
If you look after a building such as Saint Bernadette Catholic Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
What your quote should include
- How much experience the applicator has
- Whether all the old sealant comes out first
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Damaged concrete that needs breaking out and repairing
- Water getting under the tiles from elsewhere
- A tiled floor that needs relaying
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Look at floor joints each spring
- Do not paint over silicone
- Mark off resealed joints in warehouses
- Keep dirt out of the joints
Silicone sealant isn’t made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. Resealing early keeps it out.

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.
For landlords with property near Park Street station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. Community buildings like Church of St Peter are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.
