Remodel Your Bathroom

If you're looking at the current fixtures in your bathroom, and you know that you want something new, but aren't sure how to get from here to there, call John C. Flood. We'll help you:

  • Identify fixtures that conserve water, saving you money and limiting your environmental impact
  • Choose fixtures that are the right size for the space you have
  • Complete installation quickly and correctly so that you can move on to enjoying your new purchases.

Polybutylene Pipe Replacement

Depending on when your home's water system was last upgraded, you may have heard of polybutylene pipes. What you may not have heard is that this material was the subject of a class action lawsuit, and may rapidly degrade under normal use. If you have poly pipes in your home, John C. Flood, is uniquely positioned to help you upgrade to a more durable material before you suffer loss and damage to your home due to broken pipes. We served as an expert lawsuit in the class action lawsuit.

Whatever your plumbing needs may be, trust John C. Flood, as the plumbing company in Gaithersburg that can meet them. From Crown Farm to Science City, we'll help you get the water running into and out of your home as smoothly as possible. We understand that disruptions to your plumbing are frustrating and difficult, and we'll help you through them as quickly as we can. Contact us today to schedule a repair, whether it's as small as a toilet that doesn't quite flush, or as big as a brand new water heater.
