New homes and floors in Highmoor Cross
Across Oxfordshire, 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 is why the skirting and threshold joints need a flexible seal.
Rented homes near Henley-On-Thames station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Get cracks along tile grout lines looked at early
- Use furniture pads near skirting
- Keep heavy wheels off new concrete joints until cured
- Vacuum floor joints regularly to stop grit building up
Keep off the joint for the time we give you. Light foot traffic is normally fine sooner than wet cleaning or wheels.
Small gaps are quick to seal. Left alone, they collect dirt and widen.

Common problems we fix in Highmoor Cross
Caulk is the usual filler for skirting. It cracks where there’s movement or water.
Signs it’s time to call us include:
- Gaps at thresholds between rooms
- Cracked caulk along skirting in bathrooms and kitchens
- Skirting that has pulled away from the floor
- Perimeter joints in tiled floors filled with grout
Community buildings like Church of St Paul are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most rooms, longer for large commercial floors. Somewhere as small as Highmoor Cross, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the gap and the floor type and agree the right sealant.
- We take out any old caulk, sealant or grout along the line.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
How to prepare
- Mention if the joints have been sealed before
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Advice
Leave it or put it right?
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 Highmoor Cross, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Why choose Mr Mastic in Highmoor Cross
