An unpleasant odor kept coming from the bathroom drain despite regular cleaning. The plumber found that debris was trapped deeper in the pipe where surface cleaners couldn’t reach. A thorough cleaning removed the buildup completely. The smell hasn’t returned since.

A visit yesterday from Flatirons Plumbing was a pleasure. Caesar arrived on time and immediately knew what our problem was. After checking his truck for the part that he needed (he had one), the repair was quick and our leaking drain was fixed - I had tried to repair it but knew I did not have the right part and was hesitant to attempt buying, let alone installing, what was needed. Caesar was a delight to work with, personable, knowledgeable, very focused on helping us resolve our problem, and should we have other plumbing problems in the future we shall always call Flatirons Plumbing. . . and ask for Caesar!

I was extremely pleased with Flatiron Plumbing. They were able to come out the same day that I called and Anthony the technician was very pleasant, knowledgeable and helpful. We have used them several times now and have always been very pleased.

The technician, Anthony, was great, professional, efficient, and did solid work after he had to go get parts. The price was quoted upfront and I agreed, not knowing the job would take under 30 minutes or be as simple as capping two water lines and one gas line with easy access. The $575 final bill later felt well above market. When I contacted the office, I did not ask for a specific price reduction. I intentionally left any adjustment to their judgment, in good faith, believing they would assess what was reasonable. Instead, I was told that because I accepted the quote, I needed to state what the job was “worth.” When I declined to name a number and asked them to determine a fair adjustment, the office manager became rude and refused any consideration. That response reflects poor customer service. A small goodwill adjustment would have kept me a satisfied, repeat customer. Unfortunately, the office response overshadowed an otherwise positive experience with the technician.

I had the best experience with Planet plumbing. They were open, honest, hardworking and had fair pricing after a thorough inspection was carried out to see what the problems we had were. Saul was our tech and he is a spectacle of professionalism. He was not satisfied unless he had it done the right way. He stayed late to make sure the job was done in a timely manner to allow for the use of the home while they tore up the concrete slab to fix the main drain in the older home. The old cast iron pipes were extremely scaled up with buildup over the past 60 or 70 years. They came quickly to evaluate and gave a fair quote didn’t change the price on us and scheduled right away to fix the problem. I would use them again in a heartbeat. If I have any plumbing problems in the future, I don’t even see a reason to call anyone else. I will even ask for Saul by name when I call.

We had our counters and sink installed today and thought we wouldn't have time to have a plumber come and install our garbage disposal and faucet but the installers finished by 11 AM. I started calling plumbers to see if somone could quote us today. We had a plumbing quote in the early afternoon that I thought was too much and we were luck to get in touch with Planet Plumbing who quoted us half the previous quote at 5:00 PM. They were professional and did the quote in an informative way. We agreed and they started the work immediatly and finised with by 7:00 PM which was amazing they were willijng to go above and beyond on the evening before the 4th of July. Jessie and Ben were professional and did a great job installing our faucet and garbage disposal. We are grateful for their service and could not recommend them more. Post Number 2. December 19, 2025. We had some molding installed 5 months ago. After getting some items for Christmas decorating out of the crawl space, I noticed that some of the items were wet. I looked up at the plumbing and found that water was coming down one of the pipes that seemed to increase when the upstairs shower was on. I called late at night and Planet Plumbing set up an appointment the next day. Chase and Collin came to the house, I told them that base on where the pipe went up, I thought it might be a nail from the molding. They looked around and said that it made sense but they wouldn't know until they opened the wall. They opended a small space in the dry wall above the pipe and sure enough a nail went through the molding to a pipe that was leaking. They cut and replaced the pierced pipe expediently and for a fair price and even found some other issues that they recommended we consider fixing. Thankful we have Planet Plumbing to call on them. We have used them 3 times this year and have been impressed with the professionalism and fair price each time.

This is a reveiw for Michael Longwell who performed plumbing services for a rental porperty owned in Boulder, CO. Our rental unit is located in a two-story condominium with an underground parking garage. In early January 2026 a leak was discerned in the garage. Numerous plumbers came to the property but were unable to figure out where the leak was coming from. The HOA of the property then called Planet Plumbing and Michael Longwell came out to inspect the problem. Within 30 minutes Michael figured out exactly where the leak was coming from and what unit in the property the leak emanating from. The leak was coming from the tub in the unit above our unit. Michael determined to locate the leak he would need to go into the bathroom wall of our unit, so we scheduled a time for Michael to go into our wall. Within 15 minutes Michael located the cause of the leak, which was an HOA pipe, and the leak was 100% fixed within an hour. All can say is Michael was a fantastic in every aspect of the work he performed as he was courteous professional and knowledgeable. If we have a need for another plumber in the future, we will be reaching out to Planet Plumber and specifically requesting that Michael be put on the job. Thanks for the great work, Michael. You were a pleasure to work with. Brad

Professional Drain Cleaning in Longmont, Colorado

Longmont’s unique blend of historic charm in Old Town and rapid new development near the St. Vrain River creates a diverse range of plumbing needs. Whether you are dealing with a stubborn kitchen clog in a modern home near Sandstone Ranch or a complex sewer backup in a vintage property near Thompson Park, finding a plumber who is actually available when you need them shouldn't be a chore.

Our specialized service takes the stress out of home maintenance by doing the heavy lifting for you. We don't just give you a list of names; we actively filter our network of certified Longmont technicians by your specific zip code. We then call them to verify they have the equipment and the schedule opening to solve your drain issue today, ensuring you don't waste time on providers who are booked out for weeks.

Common Drain Issues in Longmont, Colorado

Hard Water Mineral Build-up: Longmont, like much of the Front Range, often deals with mineral-rich water. Over time, calcium and magnesium deposits can create scale inside your pipes, catching debris and causing frequent, slow-moving clogs that standard DIY methods can't clear.

Root Intrusion in Historic Districts: In neighborhoods like Old Town, the beautiful mature trees that line the streets are a major draw, but their roots are a nightmare for clay sewer pipes. Roots seek out the moisture in older lines, leading to total blockages that require professional rooter service or hydro-jetting.

Shifting Soils and Pipe Bellies: The geography near the St. Vrain Creek can lead to soil shifts. This often causes 'bellies' or sags in underground sewer lines where water and waste pool, leading to recurring backups for Longmont homeowners.

Kitchen Grease and Disposal Misuse: With a thriving local food scene and a community that loves to cook with fresh ingredients from the Boulder County Farmers Markets, grease and fibrous vegetable scraps are common culprits for kitchen sink clogs that require professional attention.

Seasonal Drain Maintenance Tips for Longmont, Colorado

Spring Thaw Prep: As the snow melts off Longs Peak and local runoff increases, ensure your basement floor drains are clear. High ground moisture in Longmont can cause older drainage systems to back up during the spring thaw.

Fall Leaf Management: Before the first Colorado freeze, clear your outdoor area drains and gutters. Longmont’s dense tree canopy drops significant debris that can wash into your drainage system and freeze, causing pipe bursts.

Winter Pipe Protection: During extreme cold snaps common in Boulder County, keep your cabinet doors open to let warm air reach pipes, and ensure your main drain line is clear to prevent slow-moving water from freezing inside the pipe.

Summer Harvest Disposal Care: When enjoying summer produce, avoid putting corn husks or fruit pits down your disposal. These are a leading cause of mid-summer plumbing emergencies for Longmont residents.

Average Drain Cleaning Costs in Longmont, Colorado

$175-$450

Prices in Longmont typically range from $175 to $450 for standard drain cleaning. Factors affecting the final cost include the location of the clog (main line vs. secondary line), the time of day, and the specific equipment required, such as motorized snakes or high-pressure hydro-jetting.

Frequently Asked Questions about Drain Cleaning in Longmont, Colorado

Why is it so hard to find an available plumber in Longmont?

Longmont's rapid growth means local service pros are often overbooked. Our service solves this by calling plumbers in your specific zip code to confirm they are actually available to show up today before we connect you.

Does the hard water in Longmont affect my drain health?

Yes, hard water scale builds up inside Longmont pipes, narrowing the passage and making clogs more frequent. Professional descaling is often necessary for older homes in the 80501 area.

Do you service all parts of Longmont, including the newer developments?

Absolutely. We filter our network for all Longmont zip codes, including 80501, 80503, and 80504, covering everything from the historic center to the newer communities near County Line Road.

Are the plumbers in your network familiar with Longmont building codes?

Yes, we only work with certified technicians who understand the specific municipal codes and permit requirements for both the City of Longmont and Boulder County.

What is the most common cause of sewer backups in Longmont?

In older areas, root intrusion from mature trees is the top cause. In newer areas, it is often a combination of grease buildup and 'flushable' wipes that get caught on minor pipe imperfections.
