"Stay far away from this company. Original project went fine although it was expensive. However the past few months have shown me their true colors as I have tried to get some of the original work fixed. Be aware that they only warranty work for 12 months. We had the only four tiles on the step into our shower crack over the first year and I tried for months to contact them through email. No response. I finally left my name as a new customer, and they immediately called me (funny :)). They then asked for pictures and said they could fix it. I then discovered it would cost $600 to replace the four tiles they obviously installed incorrectly the first time. Correctly installed tiles would not all crack on the outer edge."

"Chris Stumpf and his team were amazing! They remodeled all three of the bathrooms in our rental property. Since it is a rental, we needed the materials to be hardy and we were on a budget. Not only did Chris and his team do a beautiful job on our baths, they also completed a great deal of smaller projects that needed to be done. I would highly recommend using Chris Stumpf and his team for your next bath remodel!"

"Let’s just say communication was stellar from the get-go! We met with Tom to go over what work we wanted to do and there’s just something about making a personal connection with someone that makes you feel confident that the work they’re going to do for you is going to be great, and it was! Can’t say enough about Tom and his brother Jesse‘s professionalism, knowledge and skill!! Along with countertops, we were also installing some unfinished cabinets and we didn’t even know it was an option, but Tom offered without us asking to prime and paint them for us as well, AND he even went and matched the paint so the new cabinets matched the old ones we were keeping, which was great because we were under a time crunch to get this work done before family was coming to stay with us. Tom and Jesse worked with us to make sure everything was completed and that we were 100% satisfied in the short amount of time they had to get it done for us. Everything looks beautiful and we would definitely work with Tom and Jesse again in the future! Actually, hoping to have them come back and do some laminate flooring for us as well! Highly recommend these guys, they are great guys, great communication, 100% trustworthy and I guarantee they will do a great job for you!"

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.
For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.
Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.
Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.
A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
