"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

The Merrimac, WI homeowners’ guide to plumbing services
From average costs to expert advice, get all the answers you need to get your job done.

Making updates to your home? You may need to move your gas line to fuel new appliances or meet code regulations. We’ll cover the cost of moving a gas line, plus project tips.

If you need to pump sewage waste uphill to reach a septic tank or street sewer, you may need a dedicated grinder pump. Follow our guide to determine how much a sewer grinder pump costs and any prices that may creep up during the install.

Wondering how much it costs to reroute plumbing? We have the information you need to learn about plumbing vent pipes and cost considerations when installing them.

It’s a big issue when no cold water is coming out of the faucet. Whether it’s a pipe problem or something else, take these steps to identify the cause and get cold water flowing again.

If you need trenchless sewer repairs, you’ve no doubt asked yourself, “What is pipe bursting?” This guide answers that question and so much more.

Having the right size PEX pipe is a must for your plumbing project. Learn about PEX pipe sizes and dimensions so you can choose the right one for your project.
