How we handle floor joint sealing in Northaw Valley
Across Northaw Valley, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, because the right sealant depends on both. If you have skirting that has pulled away from the floor and threshold joints that have opened or worn, we can put it right.
Somewhere as small as Northaw Valley, 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.
Big or small, it’s backed by our one-year guarantee.

What happens if it’s left?
Left open, concrete joints break down under traffic. A sealed joint supports the edges. Where a wall is exposed, as many are in small places like Northaw Valley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Looking after it afterwards
Looking after new joints is easy:
- Lift furniture rather than dragging it across joints
- Don’t fill floor joints with caulk where they move or get wet
- Avoid sloshing water against skirting
- Ask before painting over a sealed joint
Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant.
Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further.
How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours, depending on the length of joint. Somewhere as small as Northaw Valley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- 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.

Wheels crossing an unfilled concrete joint chip its edges. Pallet trucks and trolleys knock the edges away until the joint widens.
If you can see any of these, it’s time to have the joints looked at:
- Caulk that has cracked where the floor moves
- Grout cracking in a straight line across a floor
- Open gaps along the bottom of skirting boards
- Gaps at thresholds between rooms
Letting a property close to Crews Hill station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

What floor joint sealing looks like in Northaw Valley
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. The joint at the skirting or threshold has to allow for that.
If you look after a building such as St. John's Senior School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. For buildings such as Parish Church of St Thomas A Becket, floor and skirting joints in halls and kitchens wear like any others.
