The nightmare of clogged drains, overflowing toilets, or grease-filled kitchen sinks is no longer unfamiliar to households in Hanoi. Amidst rampant “clickbait” ads promising 50k - 87k services, Green Environment offers a professional drain unclogging solution starting from just 100,000đ, incorporating all 5 of the most advanced technologies available today to definitively resolve even the toughest blockages.

1. Beware of the “50k Service” Trick — A Costly Lesson

When searching on Google or encountering unmarked flyers, you might easily be drawn to unbelievably cheap prices like 50k or 87k. In reality, these are psychological “misconceptions” that have caused many residents in newly merged wards like Phuong Lien - Trung Tu or Kham Thien - Trung Phung (Dong Da), as well as in Hai Ba Trung and Thanh Xuan districts, to pay dozens of times more.

”Diagnosing” Fake Problems for Exaggerated Quotes

Unreputable technicians often quote 50k to come to your home, but then give reasons like:

“Your pipes are fossilized; we need to use imported chemicals costing 1 million/liter.”
“A normal spring machine won’t work; we need a high-power machine, charged at 500k/meter of cable.”
Result: Quoted 50k, but the final bill reaches 3-5 million VND.

At Green Environment, the 100k price is real. This is the starting price for basic unclogging packages (toilets, sinks) using an air compressor or camera inspection, with a commitment to transparency and a fixed-price quote provided before work begins.

2. Top 5 Advanced Unclogging Technologies at Green Environment

To provide thorough solutions, we rely not just on manual effort but on the power of modern machinery. Depending on the type of waste and pipe structure, our technicians will select the most suitable technology:

2.1. Industrial Spring Machine v6.0 (GQ-150)

This is the “nemesis” for hard foreign objects like hair, rags, plastic bags, or tree roots that have entered the pipes.

Mechanism: A double-helix spring cable delves deep into every bend, breaking down blockages without scratching ceramic glaze or cracking plastic pipes.
Advantages: Can clear pipes up to 60 meters long.

2.2. High-Pressure Air Compressor (50 Bar)

Suitable for sudden blockages in toilets or kitchen sinks caused by soft materials or excessive toilet paper.

Mechanism: Uses an extremely powerful stream of compressed air to create pressure, pushing foreign objects directly into the septic tank.
Advantages: Extremely fast execution in just 5-10 minutes, absolutely clean.

2.3. Hydraulic Jetting Machine (High-Pressure Flushing)

This technology is often used for restaurants and eateries in the Old Quarter or Cau Giay area, where pipes are constantly coated with “fossilized” hardened grease.

Mechanism: Uses a 200 bar water jet to flush the entire pipe wall.
Advantages: Cleans up to 99.9%, much like replacing the pipe itself.

2.4. HD Endoscopic Camera Inspection

We don’t “guess” the problem; we “see” it.

Mechanism: An infrared camera head is inserted into the pipe to precisely locate the blockage and its cause.
Advantages: Avoids unnecessary demolition of the customer’s floor.

2.5. Microbial & Nano Silver Odor Removal Technology

After unclogging, Green Environment adds microbial agents to break down residual grease and uses Nano Silver to thoroughly disinfect and eliminate odors.

5. Frequently Asked Questions (FAQ)

1. Is 100k an all-inclusive price or just a travel fee?

Hello, the 100k price is the starting unit price for quick solutions using an air compressor for minor blockages. We commit to surveying and providing an all-inclusive quote before starting work. If you agree, we proceed; if not, we are happy to leave, and you will not incur any survey fees.

2. Will the spring machine damage Tien Phong plastic pipes?

Absolutely not. Our spring cable is a specialized v6.0 flexible steel type with extremely high elasticity. The machine merely rotates to break down foreign objects; it does not puncture or crack plastic pipes.

3. I run a restaurant, and my drains are constantly clogged with grease. What should I do?

For restaurants, we recommend using the high-pressure Jetting method once a year. This method will strip away all grease buildup on the pipe walls, making the pipes as clear as new, which is significantly more effective than merely unclogging with a regular spring machine.

4. How long is the warranty period?

Toilet and sink drain unclogging services typically come with a 3-6 month warranty. For periodic unclogging contracts for buildings or system flushing, we offer a warranty of up to 2-3 years.

5. Do you work at night or on holidays?

Green Environment is on duty 24/7, regardless of holidays or late nights. Notably, we do not increase prices during night hours to support customers facing urgent issues.

6. Can I unclog the drain myself using drain cleaner powder?

You can try if it’s only a minor blockage caused by organic waste. However, if the blockage is due to old grease buildup or hard foreign objects, drain cleaner powder can cause precipitation, worsening the blockage, and the high temperature from the chemical reaction might deform thin plastic pipes.

Conclusion: Be a Smart Customer

Drain unclogging is a service that requires trust and high technical skill. Don’t let a 50k price on a flyer blind you into paying unreasonable amounts later.

Let Green Environment take care of your home’s drainage system with dedication and the most modern technology.
