Kitchen faucet was leaking into the cabinet. OnGrade was on time and fixed the faucet quickly. Mentioned the thermostat wasn't working and they put a new one in for me for a few hundred dollars. Now I can control the heat and AC from my phone.

Came home and the toilet was broken and just running water for who knows how long. 28 minutes after my call, they were there, stopped the water, and fixed it way faster than I even hoped for. My first call will always be here!

I heard about this company from a friend who highly recommended them. I needed some work done on a tub drain, and it turned out to be the entire p-trap that needed replacement. The highly knowledgeable plumber, Colton, diagnosed and replaced everything quickly and efficiently. These guys are the best!

I had a fantastic experience using OnGrade Plumbing. From the moment their plumber arrived, he was on time, efficient, knowledgeable, friendly and overall very professional. He clearly takes pride in his work. He did a thorough review and provided us with several options for repairs. Will use again if the need arises.

Colton replaced my water softener and flushed my water heater. He was prompt, made helpful suggestions, and kept a clean work environment. His price was lower than I expected. I was very pleased and will use him and this company again.

FAQ

Frequently Asked Questions

Straight answers about scheduling, pricing, permits, and the work itself.

Yes. OnGrade is one local crew for both the dig and the pipe work, so you don't have to coordinate multiple contractors. We manage sewer and water service line replacements, underground gas lines, and site work end-to-end across Northern Colorado — including permits, locates, pressure testing, and clean backfill.

For active leaks, sewer backups, or no-hot-water situations, we aim to be on site the same day whenever possible. Call our office and we'll confirm a clear arrival window, give you steps to limit damage in the meantime, and bring the gear to diagnose and fix the issue on the first visit.

Yes. OnGrade is fully licensed and insured, and every job is completed to current Colorado plumbing and excavation code. We pull permits when required, coordinate inspections, and document the work so your home, build, or property stays compliant and protected long after we leave.

We install, repair, and replace all types of water heaters including traditional tank, tankless, heat pump, and high-efficiency models. We'll assess your household's hot water demand, energy preferences, and budget to recommend the best system for your home.
