Chimney hole cutting is the process of making a clean, round opening in a kitchen wall so the exhaust duct of a chimney can carry smoke, oil vapour and cooking odour outside. In Jalandhar, the neatest way to do it is with a diamond core drilling machine, which cuts through brick, concrete or RCC with very little vibration, dust or damage to tiles and plaster. A well-placed hole means better suction, a quieter kitchen and a tidy finish.

The Kitchen That Smells of Yesterday's Tadka
Anyone who cooks in a Punjabi kitchen knows the routine. Tempering spices in hot oil, frying parathas, slow-cooking dal, roasting masalas: every one of these creates smoke, grease and strong aroma. Without a good exhaust path, the smell clings to curtains, the grease coats the cabinets, and the walls turn sticky and yellow within months.
A kitchen chimney is meant to solve this, but a chimney is only as good as its exit route. If the duct is long, bent in too many places, or ends at a badly cut hole, even an expensive unit will struggle.
That is why the humble hole in the wall deserves more attention than it usually gets. Getting chimney hole cutting in Jalandhar right is the difference between a kitchen that stays fresh and one that merely has a chimney hanging above the stove.
What Is Chimney Hole Cutting?
Your chimney captures smoke and fumes over the hob and pushes them through a duct pipe. At some point that pipe must pass through the outer wall. The opening created for it is the chimney hole.
Core cutting creates this opening with a hollow cylindrical bit studded with industrial diamonds. The machine spins the bit and grinds a circular hole of exactly the size you need, usually with a small supply of water to cool the bit and keep dust down.

Why Not Just Break the Wall by Hand?
Many kitchen contractors still reach for a hammer and chisel. Here is why that tends to go wrong.
- Cracked tiles. Kitchen walls are often tiled up to the ceiling. Impact can crack tiles several feet away from the actual hole.
- Uneven opening. A chiselled hole is rarely round, and the gap around the duct has to be filled with cement or sealant that looks patchy.
- Dust in the whole house. A single hour of breaking sends fine concrete dust into cabinets, utensils and open food areas.
- Risk to hidden pipes. Kitchen walls often carry water lines, electrical conduits or gas pipes. Hammering blindly is risky.
- Noise. Particularly troublesome in flats and apartment buildings.
Core drilling avoids almost all of this, since it cuts with controlled rotation instead of impact.
Chiselling vs Core Cutting for Chimney Holes
| Point | Core Cutting | Chiselling |
|---|---|---|
| Shape of hole | Clean and round | Irregular |
| Vibration on tiles | Very low | High |
| Dust | Water-controlled | Heavy |
| Duct fit | Snug and neat | Gaps to fill |
| Risk to hidden services | Lower with proper checks | Higher |
| Time on RCC walls | Short | Long |
| Finish quality | Ready for sleeve or sealing | Needs patch work |
Choosing the Right Hole Size
The duct diameter depends on your chimney model. Many domestic chimneys use a duct of around 6 inches (about 150 mm), while some models use 4 inches or 8 inches, and heavier commercial exhausts can be much larger.
Do not guess. Check:
- The chimney manual or specification sheet. It will name the exhaust outlet size.
- Your installer's advice. They know how the duct and any outer cowl or non-return flap will fit.
- Whether a sleeve is being used. A sleeve inside the hole can affect the final diameter required.
Share this number when you enquire, and the correct bit can be brought to the site on the first visit.
Position Is Everything: Planning the Perfect Spot
A chimney works best when its path is short and straight. These planning tips help:
Keep the duct run short. The shorter the distance from chimney to outside, the stronger the suction. Long ducts lose airflow.
Limit the number of bends. Each elbow reduces performance. Aim for a straight or gently angled run.
Choose the right height. The hole is usually placed high on the wall or near the ceiling, in line with the duct from the chimney top. Mark it with the chimney in place or with exact dimensions.
Give a small outward slope. A slight downward angle toward the outside helps grease and condensation drain away from the kitchen instead of back toward the chimney.
Keep away from beams and columns. Do not cut near structural elements without checking. Move the hole slightly rather than risk cutting through reinforcement.
Watch out for hidden services. Electrical conduits, water lines and gas pipes may be inside the wall. Ask for a scan or check wiring plans if you are unsure.
Think about the outside. A hole facing a neighbour's window, a shared passage or a busy balcony may cause complaints. Choose an outlet where fumes can disperse freely.
How the Work Is Done at Your Kitchen
Here is what a neat, professional visit typically looks like.
- Short consultation. The team confirms duct size, wall thickness and the intended position.
- Marking. The centre point is marked and approved by you or your chimney installer.
- Kitchen protection. Counters, stove and floors are covered. Cabinets are closed or wrapped.
- Machine setup. The core drill is fixed firmly so the hole stays straight and aligned.
- Cutting with water. The bit passes through tiles, plaster and masonry or concrete, with slurry controlled.
- Core removal. The cylinder of wall material is taken out in one piece.
- Cleanup. The slurry is wiped away and the area left tidy.
- Final check. You confirm size, height and slope before the team leaves.
Most chimney holes take only a short time to cut, though thick RCC or awkward access may take longer.
Special Situations Worth Knowing About
High-rise flats and apartments
Check society rules about drilling hours and façade changes before you start. Core drilling is far quieter than breaking, which helps in shared buildings.
Old brick houses
Older walls may be thick, and the plaster may be fragile. Core cutting protects delicate finishes better than impact tools.
RCC walls and shear walls
Reinforced concrete needs diamond cutting. If the wall is structural, consult an engineer before choosing the hole position.
Restaurants, dhabas and commercial kitchens
Commercial exhausts are larger and may need more than one opening. Planning the layout in advance avoids repeated cutting.
Open kitchens with islands
Where the chimney hangs over an island, the duct may need to go up through the ceiling or run along a wall. The cutting method and position change accordingly.
Why Proper Chimney Hole Cutting Improves Kitchen Performance
A neat, well-placed hole does more than look good.
- Better airflow. A straight, correctly sized opening lets the exhaust move freely.
- Less grease on walls. Strong suction means less oil settles on cabinets and tiles.
- Quieter operation. A snug duct without rattling gaps reduces noise.
- No leaks. A properly sealed, correctly sloped hole prevents rain and condensation from entering.
- Cleaner finish. A round hole with a neat sleeve looks professional from both inside and outside.
What Affects the Cost?
Prices vary because every kitchen is different. Common factors include:
- Hole diameter
- Wall thickness and material (brick, concrete, RCC)
- Reinforcement density
- Height and ease of access
- Number of holes needed
- Location within Jalandhar or nearby areas
- Special setup for tight spaces

Mistakes to Avoid
Cutting before the chimney is chosen. Different models need different duct sizes. Decide first, then drill.
Placing the hole too far from the chimney. A long duct reduces suction.
Ignoring the slope. A hole angled inward invites water and grease to run back.
Skipping the wall check. Cutting blindly near hidden pipes or wires can cause costly damage.
Using a ragged opening. A rough hole is hard to seal properly and can look unfinished.
Going for the lowest price only. A cheap job that cracks tiles or ruins plaster will cost more to repair.

Frequently Asked Questions (FAQs)
What is chimney hole cutting?
It is the process of making a round opening in a wall for the exhaust duct of a kitchen chimney, usually with a diamond core drilling machine.
What hole size is needed for a kitchen chimney?
Many domestic chimneys use a duct of about 6 inches, but sizes vary. Check your chimney's specifications or ask your installer before cutting.
Is core cutting better than breaking the wall by hand?
For most kitchens, yes. It produces a clean, round hole with very little vibration, so tiles, plaster and surrounding walls are better protected.
Will cutting the hole crack my kitchen tiles?
Core cutting greatly reduces the risk. Proper marking, a stable machine and controlled water flow help keep tiles intact.
Can you cut through RCC and concrete walls?
Yes. Diamond core bits cut through brick, concrete and RCC. If the wall is structural, avoid beams and columns and consult an engineer where needed.
How long does it take to cut a chimney hole?
A standard hole often takes a short time, depending on wall thickness and access. Thicker RCC may take a little longer.
Do I need to arrange water and electricity?
Usually yes. A power point and water access make the job smoother. Mention it if either is difficult at your site.
Can you do this in a flat or apartment?
Yes. Core cutting is quieter than chiselling, which makes it suitable for flats. Check your society's timing and permission rules in advance.
Can you also cut holes for exhaust fans or commercial kitchens?
Yes. Core cutting works for exhaust fans, ventilation lines and larger commercial duct openings. Share the diameter and location when you enquire.

Conclusion: Let Your Chimney Breathe Properly
A kitchen chimney is a long-term investment, and its performance depends heavily on the hole that lets the smoke out. A rough, oversized or badly placed opening can reduce suction, leave gaps and damage the walls around it. A clean core-cut hole gives your chimney the straight, snug exit it was designed for.
Whether you are renovating an old home in Model Town, fitting out a new flat near Nakodar Road, or setting up a restaurant kitchen close to BMC Chowk, a short conversation with a specialist before the first cut can save you dust, cracks and rework.
