Customer Reviews in Mercer Island, Washington

I’ll start with this: Yes, I would totally recommend Mr Rooter. Broken sewer pipes are never good news, and unexpected & sudden discovery is not likable. It started with an overflowing mess in our basement and ended up with a large, new section of pipe, deep in our front yard. To the rescue was Mr Rooter. After an emergency clearing of our drain pipes (fast response!), they found a “blockage” using camera probe). Turned out the pipe was broken, buried 7 feet deep. They dug down, found another break and another. Four in total. Huge tree roots had crushed the pipe. This was not an easy nor inexpensive venture. On the upside, Vinnie – our Mr Rooter project manager – was awesome. This kind of problem causes quite a disruption in our life, with the water/drainage unusable as the fix was happening, but the communication and clear explanation from a very experienced and understanding Vinnie, things went as well as could be hoped for. He and his crew were efficient, hard-working, friendly, and respectful of our needs and property – and wallet. Vinnie was refreshingly honest and candid about our options as the ordeal unfolded. Everything was handled professionally and the site was secured and blocked off, with all permits in place (and no complaints from the neighbors), and a tidy jobsite. While costs for this kind of work is not inexpensive, I think we got a fair value. Big thanks to Vinnie – and crew! We’ll use them for maintenance in the future.

-
When you’re having problems with your water heater, contact a trusted service provider who regularly works on the type of water heater you own. Enjoy peace of mind that you’ll receive high-quality water heater repairs when you hire licensed and insured water heater repair professionals. Do your research before hiring someone to fix your water heater — read reviews and testimonials or ask friends, family members, and other people you know for recommendations. During your research for water heater repairs, ask water heater repair experts whether they offer parts and workmanship guarantees before you make your hiring decision.
-
You may be able to repair a water heater that isn’t producing hot water by inspecting the heating elements and thermostat and confirming a power supply to the unit. A leaking water heater can require the expertise and experience of trusted water heater repair specialists who will diagnose problems like corrosion and failing pressure relief valves. If you hear strange noises coming from your water heater, flush the tank as sediment buildup in the bottom of it could be to blame. If you don’t feel comfortable diagnosing or repairing your own water heater problems, contact a water heater repair business in your area for help.
-
Check the manufacturer’s label on your water heater since it’s not always worth repairing a water heater if it’s older than 8-12 years old. Calculate the cost of repair versus replacement before deciding whether to repair a water heater — replacement may be worthwhile if your repair bill in the last year is half the cost of a new unit. If you’ve had to bring in service professionals to repair your water heater multiple times, consider a replacement rather than more repairs. Whether or not it’s cost-effective to repair a water heater can sometimes depend on its performance and efficiency to date.
-
If your water heater is leaking due to corrosion, your local water heater specialist will usually recommend replacement rather than repairs. When your water heater starts leaking from fittings or pipes, check the inlet and outlet pipes, as tightening them with a pipe wrench may solve the issue. Faulty temperature and pressure relief valves are safety features that can fail and cause water leakage, seeing the need for plumbing service providers to replace them. If you have water leaking from underneath your water heater, take a look at your drain valve — if it’s open or loose, it may be the cause of the leak – contact a trusted water heater repair expert for help.
-
While the national average for water heater repair is around $600, expect to pay more to repair an older water heater than a newer one, especially if it’s not in great condition and has multiple issues that require repairs. Electric, gas, tank, and tankless water heaters can all have different associated repair costs, so keep this in mind when hiring a plumbing service provider. How much you can expect to pay for your malfunctioning or broken water heater can depend on the issue, like sediment buildup, a leak, or a broken thermostat or element. Labor costs can make it challenging to know how much it costs to repair a water heater since they vary across cities and regions.
-
How much it costs to buy and install a new water heater depends on the model you purchase, with gas, electric, tank, and tankless units often costing different amounts. If you want to buy a water heater with a large tank or a high flow rate, expect to pay more than if you chose a small tank model or a tankless water heater with a lower flow rate. A number of factors can play a part in your water heater replacement costs, such as the company you choose to install it, the need for a permit, and how easy or complicated it is to install in your preferred location. For the most accurate estimate of water heater replacement costs, reach out to a local, trusted water heater replacement service for an accurate job estimate.
-
You should consider replacing a water heater if it’s over 10 years old and no longer efficient or economical to run in your home or business. Water heater replacement makes sense when you’ve spent around 50% of the cost of a new one on repairs within the past year. Keep an eye out for any rust on your water heater tank, which can quickly lead to a leak, indicating the possible end of its service life. When your current water heater isn’t large enough, doesn’t have the features you want, or isn’t as efficient as you’d like it to be, these are good reasons to upgrade.
-
The water heater you want to install contributes to the timeframe for replacement in your home or business. Installing a new water heater usually takes at least three hours and up to five hours, but you can contact your local, trusted water heater service provider for a more detailed estimate. Your existing plumbing connections and whether or not they need to be repaired, replaced, or installed for the first time can contribute to the timeline for water heater installation. It may take longer than the average three to five hours to replace a water heater if instalation of a gas line is required or if modifications are needed to accommodate the new unit.
-
The typical lifespan of most water heaters can determine how often you need to replace a water heater. If you have a high-efficiency water heater, you may enjoy up to 15 years of faithful service, while standard commercial and residential water heaters typically function at their best for eight to 12 years. Homeowners with tankless water heaters that have been professionally installed and well-maintained may enjoy around 15 to 20 years of consistently excellent service. Many factors contribute to the eight to 12 year expected lifespan of a water heater, like the water quality in your area, necessary repairs and maintenance, and its overall performance.
-
Some house buyers may be willing to spend a little more for a house if it has been modernized with a new installed water heater and other plumbing upgrades. Installation of a new water heater or one that is well-maintained, can be a sign to buyers that you care about your property and have taken necessary steps to ensure it’s well-maintained, potentially making it worth more. Things like a kitchen and bathroom remodel, and appliance upgrades like a new garbage disposal or water heater replacement can help increase your home’s resale value. Water heater replacement is one of many factors that can influence a property’s value, but broader market conditions often play a larger role in pricing decisions by soon-to-be homeowners.
