Expert Steam, Gas & Electric Boiler Repair in Milwaukee

We work on all types of boiler heating systems including hot water boilers (the most common type), steam boilers (less common) and combination (combi) boilers, which provide both heat and hot water.

Boilers are often called hydronic systems because they use water instead of air to distribute heat throughout your home. Some hydronic systems circulate hot water through pipes and radiators, while others use radiant floor heating (circulating hot water through tubing in your floors). Trust our experienced team for fast, reliable boiler repairs.

Common Boiler Repair FAQs

How much does it cost to fix a boiler?

We’ll need to inspect your boiler to provide an accurate price. With Prompt, you’ll get a clear, upfront quote before any work begins—no surprise charges.

Should I repair or replace my boiler?

Most boilers last 15–20 years with regular maintenance. If your unit is aging, inefficient or needs frequent repairs, a replacement may be more cost-effective. We’ll inspect it and help you decide what makes sense.

Why is my boiler leaking water?

Leaks can result from corrosion, worn seals, high pressure or stress fractures. Improper installation or pump failure may also be the cause. A technician will identify the issue and recommend a fix.
