Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"Plumbing 1 builders was the perfect team to come and help us with our needs. We got a full hardware replacement for our shower. They were quick and on time when it came to the quote process. They offered us the most competitive price in our area, while also being the most professional with the overall process. They didn’t try to upsell us on anything or spook us about our current set up, which did happen with other plumbers who came to give us a quote. They were quick and professional with the work as well. Everything exceeded my expectations in terms of execution. On top of that, they caught a weird error that was done by the builders and went out of their way to find a solution. We will most definitely reach out to them for any plumbing needs going forward!"

Gas Leak Repair questions, answered by experts

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.

No, homeowners should never attempt to fix a gas leak themselves. Gas leaks pose serious health and fire hazards. Exposure to leaking gas can make you sick, and accumulated gas can ignite and explode. So always take leaks seriously and seek the help of a pro right away. While you may be able to detect a gas leak, always call a licensed professional to handle repairs and replacements.

Some natural gas furnaces can be converted to propane with a conversion kit, but not all models are compatible. Consult a licensed HVAC pro to determine if conversion is possible and cost-effective for your system. The process involves changes to burner orifices and safety controls, and must be completed to code.

While the line can't be removed, a pro can place a cap on the end to stop leaks. Contact a pro for a service call and speak with them about the related costs of either capping or removing the line altogether. Capping a gas line will cost between $75 and $150 while removing it will start at $250.

The cost to convert a wood fireplace to gas ranges from $500 to $5,500 on average, with most people paying $3,000 for a conversion. Both wood and gas fireplaces have pros and cons—gas fireplaces are easier to clean and maintain, while fires in wood-burning fireplaces are especially warm and cozy.
