Hot water you can count on
Whether you're outfitting a new home or upgrading an old unit, we'll help you choose the right water heater for your household and install it with precision for maximum efficiency and longevity. We work with both tankless and traditional tank models, gas and electric.
If your water heater is malfunctioning, leaking or not providing enough hot water, our technicians diagnose the issue promptly and repair it effectively — so you don't have to go without.
Repair or replace?
Most tank water heaters last around 8–12 years. If yours is near that age, leaking from the tank, or needs frequent repairs, replacement is usually the smarter investment. We'll give you honest options and upfront pricing for both so you can decide.
Preventative maintenance
Regular maintenance is key to avoiding unexpected breakdowns. Our maintenance service includes tank flushing, leak detection and a thorough inspection of all components to keep your system running smoothly year-round.

“I recently contacted Bobby at Lighthouse Plumbing & Repairs. He happened to be working nearby and was able to see the repairs I needed same day…. Agreed to a 9am appt time days later (arrived early), installed a new 50 gallon gas water heater (attic) and addressed some minor issues ✔️ (Cream carpet everywhere….spotless)!! Very experienced and fair! Highly recommend”
“We highly recommend Lighthouse Plumbing and Repairs! Our hot water heater was leaking over the weekend and our home warranty company connected us with Bobby. He was able to get to us first thing Monday morning and replaced our tank by Tuesday afternoon! Fast, reliable and professional!”
“It was really cold today here in Charleston, SC around 18 degrees w/o wind chill. My outside tankless water heater froze up. Bobby came out and thawed the pipes within 15 mins, his service was great and genuinely a nice person as well. I would recommend him for work again if needed.”
“We have used Bobby with Lighthouse Plumbing and Repair two times within the last few months. This company is the absolute best. He is responsive and has taken care of our issues within 24 hours of me calling. He is very knowledgeable and shared with us how to avoid issues in the future. I highly recommend Bobby and Lighthouse Plumbing and Repair!”
“Needed a couple toilets replaced in our new home. Mr. Black was extremely easy to communicate with, knowledgeable, professional and showed up right when he said he would. Pricing is extremely fair (in fact, he beat out other quotes we received by hundreds of dollars). He has our business going forward for all our plumbing needs, highly recommend.”
“We had a busted copper pipe in our backyard. I called multiple places and none of them could come same day. I called Bobby and he was here within an hour. He was kind, funny, professional, and affordable. We will definitely call him again if needed. Top notch service!”
“Another plumber had done a horrible job “fixing” the toilet in our rental and it was still leaking after 2 visits. I called Bobby and he was able to quickly correct the problem. He completely exchanged the insides of the toilet in the same time it took the other plumber to talk about it. Bobby is the only plumber we will use.”
“Called numerous plumbers and no one could get here to fix a drain line under my house. I called Bobby one time, he showed up the next day on time, fixed the drain line, found the cause of the problem and told me what I could do to prevent it from happening again. Affordable, friendly, professional and punctual. 5 stars man, thank you.”
“I called Bobby about a leak in one of our drain lines. He came the very next morning, found the problem, explained it, and fixed it in no time. He was very courteous, knowledgeable, and fair in his pricing. I had a much better experience with Bobby than with some other companies who have come out in the past. Highly recommend.”
“If there was an Olympic sport for diagnosing and replacing a garbage disposal, Bobby would have won 1st place. The whole thing, from knock on door to sign off invoice, took less than 25 minutes.”
“Bobby you are amazing!!! Thanks so much for fixing my momma's pipes so quickly! I definitely recommend them, not only was he less $ than the other ppl I called but he was out here and done repairing the pipe within 21 minutes from the time I called!”
“Had an impossible clog in the kitchen sink. Bobby got it done in less than 30 min. Great service and affordable price. Thanks!”
“I highly recommend this company. Bobby was personable, courteous and on time. He explained what was going on and fixed the problem. I will call Lighthouse Plumbing for any plumbing needs in the future!”
“Great service. Fair price! Very courteous! I watch... he taught. I like when a tradesman does not mind educating me on what needs to be done and how it is being done and why!”

Questions? We've got answers.
How long does a water heater replacement take?
A standard tank replacement is usually completed in a few hours. Tankless conversions can take longer depending on venting and gas or electrical needs.
Should I switch to a tankless water heater?
Tankless units provide endless hot water and save space, but cost more upfront. We'll walk you through the pros and cons for your home and budget.
Why is my water heater making popping noises?
Popping or rumbling is usually sediment buildup in the tank. Flushing the tank can help — if it continues, the unit may be nearing the end of its life.
