Block paving cleaning in Castlereagh: the local picture
Castlereagh is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Wet winters in Northern Ireland make falls, edge restraints and full joints especially important.

What you get with our cleaning service
Block paving cleaning removes moss, algae, weeds and ground-in dirt from the surface and the joints, usually with a rotary surface cleaner on a pressure washer, which cleans evenly without the stripes a hand lance leaves. A biocide treatment can be applied to slow regrowth.
- Rotary surface clean at a pressure that will not blow out the joints
- Pre-treatment where needed
- Weeds and moss removed from the joints
- Rinse down of edges, steps and walls
- Optional biocide and sealer
How we find the cause
- Moss, algae, weeds and oil staining
- Walls, doors and planting to protect
- Type of block and its age
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Shade and drainage, which affect regrowth

Cleaning in Castlereagh: questions
Do you cover Belfast, Newtownabbey and Lisburn?
Yes. We cover Castlereagh and the places around it, including Belfast, Newtownabbey and Lisburn, and the rest of County Antrim.
Can you seal my drive straight after cleaning?
Only once it is completely dry and re-sanded. Sealing damp paving traps moisture and can leave a white bloom.
How often should block paving in Castlereagh be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
Will cleaning damage my block paving?
Not when it is done with a rotary cleaner at medium pressure and the joints are re-sanded afterwards. High-pressure lances held close are what cause damage.
