Serving the Northwest Washington Area

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.

    Installed a new 50 gallon lowboy electric in customers crawlspace. Previous tank had been removed the day before. Started by digging and using the chipping hammer to make room for the new tank. Once we got about 6” deep we spread sand and packed it down to make a firm bed. Placed 6 pavers and poured more sand, packed it down to provide stability to the new tank. Got the new tank in place, level. Cut the old gate valve out and soldered in a new ball valve. Extending the copper water lines about 4 feet so they could reach he inlet and outlet of the tank. Added new supply hoses to both hot and cold. Ran the T&P relief drain line out of the crawl through an existing opening that already had a gas line going through it. Opening is 10”x6”. Strapped the tank with earthquake straps and began filling. Checked for leaks. Began connecting the wiring. Checked for leaks. Once the tank had filled, I relieved air from the line through the kitchen and bathroom faucets. Returned power to the tank
