Mosman 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!
Mosman 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 Mosman 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.

Still have questions about our blocked sewer services in Mosman? Review these frequently asked questions or contact our team directly for personalised advice. We're here to help you understand the causes, signs, and solutions for sewer blockages.
Blocked sewers in Mosman commonly result from tree root intrusion, which seeks out moisture through small cracks in ageing pipes. Many properties in the area have established gardens with mature trees whose roots naturally grow towards sewer lines. Other frequent causes include flushing inappropriate items like wet wipes, sanitary products, and cotton buds, grease and fat accumulation from kitchen waste, foreign objects accidentally entering the system, pipe scale buildup over time, collapsed or damaged pipes due to ground movement, and occasionally construction debris. Regular maintenance and being mindful of what enters your drainage system can help prevent these issues from developing into serious blockages.
Key indicators of a blocked sewer include multiple drains backing up simultaneously throughout your home, gurgling sounds emanating from toilets or drains when other fixtures are used, water backing up in unexpected places such as shower water rising in your toilet bowl, persistent foul odours around drains or in your yard, slow-draining fixtures throughout the house rather than in isolated areas, and sewage overflowing from outdoor gully traps. If you notice any of these warning signs in your Mosman property, it's important to contact a professional plumber immediately to prevent potential health hazards and property damage.
If sewage is backing up in your home, first stop using all water fixtures immediately to prevent additional wastewater from entering the system. Turn off the water supply to the affected areas if possible. Place towels around the base of affected fixtures to contain any spillage, and avoid attempting to flush toilets again as this will worsen the situation. Keep children and pets away from the affected areas due to health risks. Contact our emergency plumbing team immediately, as sewage backup indicates a serious sewer blockage requiring professional attention. Attempting to resolve major blockages yourself can lead to further damage and health hazards.
Absolutely. We provide transparent pricing with no hidden costs whatsoever. After conducting a thorough assessment of your blocked sewer issue using our CCTV inspection equipment, we'll explain exactly what's causing the blockage and provide a detailed quote before commencing any work. This approach ensures you know exactly what you're paying for and allows you to make an informed decision about how to proceed. We believe in honest communication and fair pricing for all our Mosman customers.
To prevent future blockages, avoid flushing anything other than toilet paper down toilets, use sink strainers to catch food particles and debris, regularly clean drain stoppers in bathrooms, never pour cooking oils, fats, or grease down drains, periodically flush drains with hot water to help dissolve minor buildup, consider scheduling preventative maintenance like annual hydro jetting for properties with a history of blockages, be mindful of tree planting locations near sewer lines, and educate household members about proper disposal practices. Regular professional maintenance can identify potential issues before they develop into major blockages, particularly beneficial for older homes in Mosman.
Tree roots are one of the most common causes of sewer blockages and pipe damage throughout Mosman. Roots naturally seek out moisture and nutrients, and even small cracks in sewer pipes release vapour that attracts roots. Once roots penetrate the pipe, they continue growing inside, creating blockages and potentially causing significant structural damage. Species commonly found in Mosman gardens, particularly established trees, can have extensive root systems that infiltrate sewer lines. Regular CCTV inspections can detect root intrusion early, and we offer both root cutting services and pipe relining solutions to address this issue without removing valuable trees from your property.

As a locally owned company, call us for blocked drains, pipe relining, sewer clearing or any drainage service you need.
