Thornleigh Blocked Drains was the BEST and AMAZING. I called today after 9am to install the ceiling fan and check the switch board, 2hrs later Chris and Luca arrived. They advised what they can do. As soon as I agreed to the price they started the work. They were both professional, efficient, friendly and did a fantastic job. They tested everything to make sure everything is working fine and they took all the rubbish, no mess at all. I will 100% recommend them to everyone I know.
We recently had the pleasure of having an amazing team come to our home to install four ceiling fans and downlights in our bedrooms, and we couldn't be more impressed with their work. David and his colleague (unfortunately, we didn’t catch his name) were both incredibly professional, friendly, and efficient. They arrived on time, worked quickly, and paid close attention to every detail, ensuring everything was installed perfectly.
Very happy with the customer service and quality of their work. They turned up on time and fully quoted in advance. It was a pleasure to do business with Chris & Luka.
Clean, friendly and respectable. Great with pets and reliably on time. They obviously take pride in there work and I appreciate the honesty and work they have performed. 1 new ceiling fan + 3 replaced and a fan light in the bathroom replaced. Replaced the circuit board on the house and brought it into the modern era with safety switches I thought we had but didn't. I will definitely use these guys again and recommend highly to any one looking for a good sparky!
Thornleigh Blocked Drains have just finished up after a meter-box replacement and some rewiring to replace some old-style cloth wrapped cabling. They've done a great job, were really friendly and helpful, and left everything clean and tidy. They didn't even mind our dogs "helping".
David & Chris were extremely professional and quick, given they came down immediately on a 40 degree day to sort out our power issues. They not only corrected the issue extremely quickly, but explained their steps and pricing (which was the fairest of 4 local quotes). In addition, they physically showed what the problem is and tested it in front of us. Brilliant service provided by the guys. I would highly recommend.
I am happy with the work completed and the total price was very reasonable. I gave them a huge list of jobs that I needed done and they smashed it out in one day. The guys were friendly and respectful, and they left the house clean when they were done. The admin side was very prompt and organised, I'll be using them again.
Timely booking process and good communication. The electrician arrived on time and did a great quality ot work and explained everything well.
We had a bathroom exhaust fan replaced. Chris was very professional and sourced and replaced the fan within a short period of time at a good price. Will be using these guys again if needed.
The job was completed well and the guys who did it were friendly helpful and skilled. Only problem was that it cost a lot more than expected.
On time, great knowledge and expertise and found ways to make the work done as affordable as possible. Also took the time to quickly check out non-related electricals to make sure everything was safe!
Chris and Luka were absolutely fantastic, and we couldn't recommend them enough. They were very professional, efficient and diligent, while showing care to explain things in detail. Thanks again Chris and Luka!
A+ service from Chris and Luca of the Thornleigh Blocked Drains team, from coming out to do free quote, to giving us breathing space to explore our options to completing job; nothing but first class professionals. The boys did an amazing job of explaining our options from interest free finance, to explaining throughout the day what was being done. They were on-time, polite and did a solid clean before leaving.
The electrician were punctual, kept us informed about what they are doing, cleaned up after, took the old rangehood, explained the new one and guaranty, were friendly and kind.

Answers to Common Questions
FAQs About Blocked Sewers
Still have questions about our blocked sewer services in Thornleigh? Check out these frequently asked questions or reach out to our team for expert guidance. We’re here to help you understand the causes and solutions for sewer blockages.
In Thornleigh, the most common causes of blocked sewers include tree root intrusions (especially from established eucalyptus and fig trees), accumulated grease and fat, flushed wet wipes and sanitary products, foreign objects, broken or collapsed pipes, and built-up sediment. The area’s older clay pipe systems are particularly vulnerable to root infiltration and joint displacement. Regular maintenance can help prevent these issues from developing into serious blockages.
Signs of a blocked sewer include multiple slow-draining fixtures, gurgling sounds from drains or toilets, water backing up in unexpected places (like shower water appearing in toilet bowls), foul odours coming from drains, and sewage overflow from gully traps outside your home. If you notice several plumbing fixtures experiencing problems simultaneously, it typically indicates a main sewer line blockage rather than a localised issue.
First, stop flushing immediately to prevent further overflow. Try to contain any spilled water, and avoid using any other plumbing fixtures in your home as they may worsen the situation. Call Thornleigh Blocked Drains for emergency assistance, as toilet overflows often indicate a serious sewer blockage that requires professional attention. In the meantime, close the water supply valve to the toilet if water continues to rise.
We offer same-day service for blocked sewer emergencies throughout Thornleigh and surrounding areas. Our team prioritises urgent cases like sewage backups and overflows, with an average response time under two hours for genuine emergencies. We maintain fully equipped service vehicles ready to deploy at all times, ensuring we have the necessary tools to resolve your blockage promptly upon arrival.
Yes, we offer comprehensive preventative maintenance services for sewer systems, including scheduled cleaning, CCTV inspections, and preventative tree root treatments. For properties with a history of blockages or older pipe systems, regular maintenance can significantly reduce the risk of emergency blockages and extend the lifespan of your sewer infrastructure. Our maintenance programmes can be tailored to your property’s specific needs and risk factors.
