If you need a plumbing, heating, or air conditioning repair in Skagit County, the experienced and knowledgeable team at CPI Plumbing & Heating can help! However, you may have questions about your situation, and you might be searching for answers before you make the call. Here are a few of the most commonly-asked questions we receive about our business and the answers we can provide you.
Our founder, Steve Olsen, sold the company to three of his long-time employees, one of which was his son. This same leadership group has led the company since 1990.
We offer our services at regular rates: Monday to Friday from 8 a.m. to 6 p.m. However, we also offer after-hours emergency services at our emergency rates: Monday to Friday from 6p.m. to 8 a.m. and Saturday and Sunday all day, because sometimes problems don’t wait until business hours to spring up. Our business office is open from Monday through Friday from 8 a.m. to 5 p.m.
The price of a service call varies on a per-job basis, so you’ll need to call our office to get a specific answer. We do not charge on a per-hour basis, we charge per-job, so you won’t have to worry about surprise overtime fees or other costs that other companies might throw at you.
Yes. When our technician arrives on-site and conducts an inspection of the issue, they’ll give you a written price quote.
We offer a complete range of plumbing, heating, and air conditioning repairs, replacement, installation, and maintenance services for residential and commercial applications. We offer drain cleaning, leak detection and repair, water heater repairs and replacements, backflow certification, re-piping services, video pipe inspections, air conditioner and heater inspections and diagnoses, system replacement, heat pump repair, blower motor repair, and much more.
We’re so confident you’ll be completely satisfied with the services you receive that we back up all our repair work with a 90-day warranty and all our replacement and installation work with a full one-year warranty! If anything goes wrong with our solution during that time, we’ll come fix the issue again at no cost to you.
No, you don’t. As long as we can access the systems we need, we can perform all of the necessary work without you needing to be present! We are both licensed and fully-insured with a $1 million per claim liability policy, and we have an A rating with the Better Business Bureau in order to give you the confidence of knowing the job will be done right if you can’t be home while we’re there.

10/23/2020 Confirmed with customer that mainline was backed up when flushing toilet sinks were gurgling and kitchen sink drained slow. Drain line for toilet and kitchen sink are back graded, gave customer price to repipe drain lines in crawl space. Pulled toilet and used cable down drain line retrieving hair and feminine products. Drain line is still backed up so I added 50 more feet to the cable and drain line opened around 120 feet after retrieving more hair and feminine products. Set toilet back and tested multiple times verifying proper drainage with all fixtures in the house. Will give estimate to camera and locate drain line outside building. Thank you for choosing CPI Plumbing and Heating.

Customer called in with a possible leak on his main water line. The utility company had let him know that the usage was much higher than normal on his water bill. Inspected the outdoor piping and isolated between the home and the meter. The meter stopped spinning. The main shut off for the home is inside a meter box just outside the foundation. This indicates the leak is inside the footprint of the home. Entered the homes crawlspace and immediately found the source of the leak. The homes main water line is leaking from a hole in the pipe just inside the foundation of the home. Provided pricing to repair the leak. The customer accepted. Shut water off to the home and bled pressure from the system. Cut the existing main water line and installed a new coupling. Restored water to the home and inspected the repair. The repair is working as designed with no leaks present. Thank you for choosing CPI Plumbing & Heating!

I provided and installed a new pvc shower drain for the master bathroom shower. I relocated a 1/2 inch copper water line in basement bathroom ceiling. I added water and drain piping for an additional lav sink in the basement bathroom. I tested all installations and everything is in great working condition at this time.
