Lachen is a place of cold air, deep valleys and big skies. Sitting at roughly 2,700 metres above sea level, it is the last major village before the road climbs to Thangu, Chopta Valley and Gurudongmar Lake. Travellers stop here to rest, and local families, lodge owners and project teams work hard to keep buildings comfortable in a demanding climate.
Building in a place like this is never routine. And when a concrete roof needs a new opening for stairs, a skylight, a chimney, a lift or a service duct, you want the work done carefully and only once. A professional roof cutting service in Lachen gives you exactly that.
Core Cutting India uses diamond machines to cut RCC roofs and slabs along lines you approve. The opening is straight, vibration is low and dust is controlled with water, so the surrounding structure stays strong.

Quick Answer: What Is Roof Cutting?
Roof cutting is a method of removing a marked part of an RCC roof or slab using diamond-tipped saws. It gives smooth edges, causes little vibration and keeps dust low. It is used for staircase openings, lift shafts, skylights, chimney and duct openings, hatches and pipe holes.
Why Lachen Needs Careful, Planned Concrete Cutting
Lachen lies in Mangan district of North Sikkim, along the road beyond Chungthang. Lachung, Thangu, Chopta Valley, Zema and Gurudongmar lie in the same mountain region. The village has a strong community tradition and a well-known system of local self-governance, and many families run lodges and homestays for visitors travelling to the high-altitude lakes.
These are the conditions that make cutting important here:
- Cold climate: Winters are long and snowy, so owners add skylights, insulated rooms and heating flues.
- Short working season: Good weather windows are limited, so work must be quick and efficient.
- Remote location: Heavy machinery is hard to bring in, while portable cutting equipment travels easily.
- Lodge and homestay upgrades: Guest comfort depends on better bathrooms, kitchens and stairs.
- Earthquake sensitivity: Sikkim is a high seismic zone, so slabs and beams should not be shaken or weakened.
- Limited supplies and storage: Clean cutting means less debris and fewer repairs, which saves transport effort.
- Community-friendly work: Quiet, tidy cutting respects neighbours and the peaceful setting.

Equipment and Technology We Use
- Slab saw: Fast, straight cuts on flat roofs and floors.
- Wall saw: Deep, accurate cuts for openings, vertical surfaces and overhead work.
- Wire saw: Ideal for thick concrete or spots where a blade cannot fit.
- Ring saw: Handy for corners and small spaces.
- Core drilling machine: Smooth round holes in many diameters.
All blades are diamond-segmented and used with water, which cools the blade, controls dust and keeps the cut smooth. For cold-weather work, we plan around freezing temperatures and manage water supply carefully, so that cutting stays safe and efficient.

Indicative pricing: Roof and slab cutting is commonly charged per running foot or per square foot. For regular RCC slabs, simple jobs start at an affordable rate and rise with thickness and difficulty. Core holes are charged per hole, depending on diameter and depth. Because Lachen is remote, we often combine jobs where possible to reduce costs for owners.
