Hydronic Heating with PEX in Longmont
PEX is also a leading choice for hydronic heating systems, including radiant floor heating. Its ability to withstand high temperatures and resist corrosion makes it well suited for circulating hot water. If you are considering radiant heat for a specific area of your home or business in Longmont, PEX is the pipe of choice.
Copper to PEX Conversions in Longmont
Copper lines can develop pinhole leaks from water chemistry, high velocity and sometimes soil contact under slabs. Mountain homes in Colorado frequently rely on private wells, which may need treatment for iron, manganese, or natural minerals. Once a home has had several pinhole leaks, more usually follow. Converting to PEX stops the cycle and reduces the risk of hidden water damage. We use approved transition fittings wherever new PEX connects to existing copper stubs or valves.
PEX Repipe Cost Comparison in Longmont, CO
PEX repipes usually cost less than copper repipes because the material is less expensive and installs faster. The total depends on the number of bathrooms, the home's size and how accessible the attic and walls are. Drywall patching and texture matching are often included or quoted separately. We give you a detailed estimate so you can compare PEX-A, PEX-B and copper options side by side.

Polybutylene Replacement With PEX in Longmont, CO
Gray polybutylene pipe was common in homes built from the late 1970s through the mid 1990s and is known for sudden failures. Chlorine in municipal water breaks down the plastic and its fittings over time. Many insurers now ask about polybutylene when writing a policy. Replacing it with PEX removes that risk and can make your home easier to sell and insure.

GFR Plumbing stands behind our PEX pipe installations with a full warranty on both labor and materials. Specific warranty details will be provided with your estimate, but you can be confident your new PEX system is installed correctly and will perform reliably for years to come in your Longmont home.
PEX can be used for outdoor applications like irrigation lines or outdoor spigots, but it needs to be protected from direct UV light, which can degrade the material over time. When used outdoors, PEX should always be buried or otherwise shielded.
PEX piping is designed to be highly durable and has an estimated lifespan of 50 years or more. Its resistance to corrosion, scaling and freeze damage adds to its long-term reliability, making it a smart investment for your Longmont home.
We make small, targeted openings to run new pipe and patch them when done. Most homeowners are surprised by how little drywall work is needed.
A full home PEX repipe for an average-sized home in Longmont usually takes 3 to 5 days. Smaller projects or single-line replacements can often be completed in a single day. We aim to limit disruption and communicate timelines clearly.
Properly installed PEX is expected to last many decades. Manufacturers often offer 25 year warranties when their pipe and fittings are used together.
PEX must be protected from sunlight because UV light breaks down it. Outdoors it needs to be buried, sleeved or fully covered.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
