About Roof Cutting
What is it? Roof cutting is cutting a portion of an RCC roof or slab with a diamond saw or core drill to create an opening.
Why do people choose it? Because it is accurate, quieter than breaking, and causes far less vibration.
What does it cost? In Dum Dum, standard RCC slab cutting typically starts around ₹80–₹150 per running foot. The final price depends on slab thickness, steel and access.
Why Dum Dum Properties Need Careful Roof Cutting
Dum Dum is a busy, closely built part of the Kolkata metropolitan region. Residential lanes in Motijheel, Nagerbazar and Dum Dum Park share walls and boundaries. Apartment blocks sit beside older single-storey and double-storey houses. Add traffic around the metro station and airport roads, and even moving machines to a site needs planning.
Here is what that means for roof work:
- Shared walls and tight spaces. Heavy vibration can travel into adjacent buildings.
- Housing societies and flat owners. Noise rules and neighbour complaints are common, so clean and quick work is valuable.
- Older buildings. Many structures have been standing for decades and may have been extended over time.
- Upper-floor jobs. Equipment must often be carried up narrow stairs.
- Monsoon seasons. Fresh openings need waterproofing plans.
A planned diamond cut keeps damage limited to the marked area, saves time and keeps relations with neighbours smooth.
What We Cut: Our Roof Cutting Services in Dum Dum
Staircase Openings
Whether you are adding a rooftop room or connecting two floors, we cut a precise opening so the stair fits cleanly.
Lift Shaft and Lift Pit Openings

Slab Removal and Roof Repair Cutting
Where a roof portion is damaged, leaking or being rebuilt, we cut only the affected section instead of breaking the whole slab.

For AC ducts, plumbing shafts, drain pipes and cables, we create exact holes using diamond core cutting tools.
Wall, Beam and Floor Sawing
Door and window openings, beam trimming and floor cutting are also available for renovations.
Technology: How the Machines Work
Concrete is hard and steel is tougher, so ordinary tools do not give neat results. Diamond tools do.
| Tool |
What It Does |

Our Process: From Enquiry to Clean Finish
Step 1 – Contact us. Call or WhatsApp 7009679903 and share your location, slab thickness and size of opening.

Step 3 – Quote. You get a clear rate and time estimate before we begin.
Step 4 – Marking. We mark cutting lines. If you have an engineer or architect, they can approve them.
Step 5 – Safety setup. We prop the slab, cover floors and keep the area below clear.
Step 6 – Cutting. Our operators cut in a planned order.

Small openings can be done in a few hours. A staircase or lift opening usually takes one to two days. Larger commercial jobs may take longer.
