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.

    Review of CPI Plumbing & Heating

    I’m 72 and the cost of estimate seems way to high to me. The technician worked hard to get to the problem of heat pump and ductwork, and replace an outside faucet. They use flat rate pricing as opposed to actual time and parts.

    Replace leaking hose spigot as proposed. Shut water off to the home, drained the system down, cut drywall to locate hose spigot connection, removed existing hose spigot. Installed a new frost free hose spigot, restored water to the home, bled air from the system, inspected for leaks, and installed an access panel over the removed section of drywall. The new hose spigot is working as designed with no leaks present. Thank you for choosing CPI Plumbing & Heating!

    Includes waste re-pipe of wall hung laundry basin Performed work as proposed. Removed existing sink drain and piping. Cleaned area of installation. Performed installation of wall hung laundry basin and drain. The new laundry drain was 2 inch pipe as per code. The laundry box was secured with concrete anchors into the wall. After the new laundry drain and basin were installed I performed a drain test with the customer. I poured large quantities of water down the drain to test for leaks. There were no leaks when last checked and the drain and laundry basin performed as designed. I hooked up the wash machine with new braided stainless steel hoses and checked for leaks with the customer at the connections. There were no leaks when last checked. Customer was happy with her new wash machine basin and drain. Thank you for choosing CPI Plumbing and Heating.
