We write the price down first

Dan Mercer started Brassline in 2009 after years of watching customers argue over invoices. The rule then is the rule now: you agree the price before any work starts.

Dan Mercer, master plumber and founder of Brassline

We are a team of eleven, based in central Denver, with six vans that cover fourteen neighborhoods across the metro area.

Every plumber is licensed in Colorado, background-checked and trained to work the same way: shoe covers on, a photo text before arrival, a flat price before any tool comes out, and a clean floor when they leave.

Most of our work comes from people who called us once and kept the number. We would like you to be one of them.

What people say

“The boiler died on a Sunday in January. Luis was here before lunch with the part already in his van, and the house was warm again by two.”
Greg W., Washington Park · boiler repair
“They quoted the bathroom line by line, kept to the date and cleaned up every evening. Three weeks, no surprises.”
Hannah L., Cherry Creek · bathroom refit
“I got a text with the plumber’s photo and arrival time, which mattered to me as I live alone. Polite, quick and fairly priced.”
Dorothy F., Lakewood · toilet repair
