"Alex and Donavan were very thorough. Discovered more than what we called them for. We originally wanted information on sealing cracks to eliminate cricket infestation coming through cracks in stem wall. We were not interested in repairing foundation rebar which is typical in slab homes in AZ. They were knowledgeable and honest in their evaluation of our home."

"I had a serious mainline backup at my home in Sedona and reached out to City Plumbing and Rooter—and I’m really glad I did. They showed up exactly at the time we scheduled, which I appreciated right away. They quickly got to work, snaking the line to clear the blockage and then doing a camera inspection to make sure everything was fully cleared and flowing properly. That extra step gave me a lot of confidence that the problem was actually fixed and not just temporarily pushed through. They were professional, knowledgeable, and respectful of my home the entire time. Everything was explained clearly, and there were no surprises. You can tell they know what they’re doing and take pride in their work. If you’re dealing with a mainline backup or any plumbing issue in Sedona, I highly recommend City Plumbing and Rooter. Reliable, on time, and thorough—exactly what you want in a plumber."

"Brett arrived on time and replaced my water heater. He was mindful of my dogs in the area and cleaned up. The hot water heater works great. I would definitely hire him again to do my plumbing work. He is honest and upfront you won’t be disappointed!"

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.
