"Excellent customer service. Excellent finished product. West Shore Home came to install a shower in one bathroom and bathtub/shower in another bathroom. Their customer service is top tier! They took extra caution to ensure they didn’t damage or disrupt my home or other furniture as they carried their equipment in and out of the house. They encouraged me to see the progress as they worked. (Nothing to hide is always a good thing.)

Our commitment is 100% guaranteed customer satisfaction on every project. Call us today, so that we can give you a free estimate and make your project come to life!

"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level. "

Water Heaters questions, answered by experts

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

According to the U.S. Department of Energy, tankless water heaters are anywhere from 8% to 34% more efficient than regular water heaters. Exactly how much energy you’ll save depends on your household’s water usage. When you purchase a tankless water heater, you’ll also likely upgrade to more efficient technology than your current water heater, which can add to energy savings.
