The 5 Best Sewer Installation Services in Singapore Homeowners Rely On
Most people don’t think about their sewer lines until something starts to smell, or worse, back up.
In a city like Singapore, where sewage standards are strict (requiring finding the best plumbers) and the space is tight, a well-installed sewer system acts as protection for your home and health.
If you’ve noticed slow drains, foul odours, or soggy patches in your garden, it might be time to call in the experts. Here are some of the best sewer installation services in Singapore that can keep everything flowing smoothly underground.

When the sewer line in my parents’ house started backing up during a rainy weekend, Mr Plumber came through fast for us. Their team arrived within an hour and quickly diagnosed a collapsed pipe that needed replacement.
They handled the PUB permits, excavation, and new pipe installation efficiently, finishing everything in less than two days (even before Mum threw a hissy fit). The crew kept the site tidy and updated us at every stage, so things were relatively stress-free.
Their warranty covered both materials and workmanship, giving us peace of mind that we wouldn’t be left with future repair costs. We also appreciated the 24/7 emergency response and transparent, itemised quotes before work started.
For homeowners or landlords, they’re a reliable one-stop solution for drainage and sewer line issues. Their plumbers are licensed and well-versed in PUB regulations, so no worries about shortcuts or red tape problems later on.
However, prices are on the higher side (S$140 for exposed pipe leaks, with major piping replacement upwards of S$500 for HDB units) compared to smaller contractors.

Found Mr Plumber online and no regrets
Copper pipes were leaking literally for weeks, and we had no choice but to seek help. Found Mr Plumber online and no regrets. Excellent communication. Great price. Professional plumbers Thana and Khin Maung settled the issues. Finally, no waterfall feature in my home.

Before my sister moved to her Tiong Bahru condo, she had Straits Union Engineering handle all the messy underground work. They rerouted her sewer lines smoothly while keeping her kitchen renovation on schedule.
Their engineers managed every PUB submission and internal drainage drawing required by the condo’s management. It saved her the headache of dealing with multiple approvals and unclear paperwork.
She raved about how neatly the crew worked, sealing up trenches each day and keeping noise to a minimum (a big plus in a tight estate).
Their work is backed by a one-year workmanship warranty, which covers both the rerouted and original connections.
It was a pricey job (rerouting started at around S$2,000), but she did get a detailed breakdown of materials and labour before the job began. The company’s emergency plumbing division also offers quick response for future repairs and maintenance.
That said, their service rates are slightly higher than average for small-scale works.

When a cafe owner I know on the East Coast decided to expand and add new restrooms (hey, caffeine is a natural diuretic!), he engaged Nile Plumbing to handle the new sewer connection. The result was fantastic, so I asked him about the process.
They took the time to map out the layout so kitchen waste and sewage lines stayed completely separate, which is crucial for NEA and PUB compliance. Their team managed all drawings and submissions for the public utility permit.
They coordinated with the cafe’s renovation to avoid delays, as well. As for the workmanship warranty, they offered 90 days, along with clear terms covering their installation labour.
My cafe owner-pal was impressed by how they used the pipe relining method, which is a trenchless technique using a resin-capped liner, and kept the site clean throughout the project. 24/7 emergency calls are available for peace of mind, too.
But because they’re very responsive and clear about quality, their hourly labour rates are a bit higher than ultra-budget plumbers. Also, they schedule by availability for large-scale jobs, so immediate starts might need extra lead time.
Customer Review
Friendly, professional and transparent about the costs
Vincent did an exceptional job at unclogging the drains. We called him at 2:15 am, and he arrived less than an hour later. He explained in great detail what caused the choke and even gave us tips on how to prevent it. When we spoke to him on the phone, he was friendly, professional and transparent about the costs. Will use Nile Plumbing for all future plumbing needs. Thanks again!

My childhood friend’s home in Bukit Timah had sewage backing up their garden after heavy rain, which was unpleasant to say the least. His family immediately called Everyworks Singapore to replace the collapsed main sewer line that connects to the public system.
They arrived with their crew, handled the excavation, and managed the necessary PUB approvals with minimal fuss. They laid the new line, restored the driveway and garden area, and even cleaned up the site once the job was done.
They also offered a 3-month workmanship warranty and explained in detail what was covered.
The team used a pipe-bursting method, which broke the old pipe while pulling in a new one along the same path to ensure the new connection met current standards and reduce the risk of future collapse.
My pal said he appreciated the transparent estimate before work even began, and the prompt customer service that scheduled the job within the day via WhatsApp.
However, the warranty period is shorter than some competitors, and the excavation-level work means the pricing came in higher than simpler pipe repair services.

For the longest time, my grandparents’ old Toa Payoh flat kept having sewage chokes, so I finally called Teck Hien Engineering to check the vertical stack. They quickly found that the corroded cast iron pipes were the cause and suggested a full replacement with durable PVC ones.
Their team handled the entire process, including PUB permits, pipe removal, and branch clean lining. They managed to finish within three days, keeping noise levels low so the elderly neighbours won’t be disturbed.
I was there to observe, so I saw how the crew used pipe-jacking and confined-space tools designed for older HDB blocks, so the replacement was efficient and safe. We were glad for the one-year workmanship warranty covering leaks and joint failures, too.
The supervisor explained every step to us to ensure my grandparents understood the process, and went into detail about the itemised invoice. They even disposed of the old pipes responsibly according to NEA standards.
Do note that our experience was a rare one, as Teck Hien’s services lean more toward infrastructure jobs, so smaller home projects may wait longer for scheduling. We were lucky to have found an available slot for my grandparents.

Joe and Andy are both professionals with a great sense of responsibility. They solved all the plumbing issues for the house I rent. Would recommend people who are reading this review to appoint them as your trusted plumber.
