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."

"My partner and I have had the pleasure of working with Dan, David and the hardworking crew at LB Construction & Remodeling for our what is now an extensive home restoration and renovation project. I cannot express how thrilled I am with the results thus far. From start to finish, their team demonstrated an unparalleled level of knowledge, speed, and attentiveness that truly exceeded my expectations. Truthfully, I didn’t know where to begin with my project, so I was very happy when Angi.com recommended LB. Dan responded quickly and was able to meet me at the house and walk the entire site with me. I had recently purchased my house and it needed extensive repair from years of water damage, including repair and replacement of the wood framing, installation of proper drainage, and foundation work. What truly set Dan and team at LB Construction & Remodeling apart was their willingness to help me hash out the details and various plans for our projects. Dan and David patiently worked with me to explore different options, providing valuable insights and recommendations based on their extensive experience, such as navigating permitting, advising on order of operation. This collaborative approach made me the decision-making process easier and less stressful as I had never done anything like this before. The speed at which LB Construction & Remodeling worked on my projects was truly impressive. They efficiently managed their time without compromising on the quality of their work. Every step of the way, it was evident that they were dedicated to completing the project promptly, ensuring minimal disruption to my daily life. Not to mention their attention to detail and commitment to quality craftsmanship were evident in every aspect of the projects, particularly with the reframing and painting. One of the standout qualities of LB Construction & Remodeling is their exceptional attentiveness. Dan consistently paid close attention to my needs and concerns, making me feel valued as a client. An example of this was when I communicated how I wanted the trim around the windows to look, both inside and out. I sent Dan pictures to illustrate what I was expecting, and he listened to me, verified specifics of my ideas, and walked me through how they would be able to achieve the look easily. Their work was seamless and they captured my vision perfectly. Right from the get-go we felt a sense of trust with Dan and team and that really helped make this entire process enjoyable. I wholeheartedly recommend LB Construction and Remodeling to anyone seeking a trustworthy and skilled team for their home improvement needs. I am eager to continue our other home projects with LB Construction & Remodeling in 2024."

"Though I am happy with the final result, I feel that TJ did a bit of a bait and switch. The person who showed up, Felipe, was from a different company. "TJ" quoted me $900 for the job and $300 to move washer and dryer to access the main valves. That's $1,200. In the end, washer and dryer were not moved. But I did ask them to replace a faucet cartridge in my bathtub, which they did. But before that, Felipe had managed to turn off the water to my unit without moving washer and dryer. He then had to cut into drywall to locate the outbound pipes, but made a mistake. The next cut he made found the water pipes but these were the wrong pipes. An emergency water shutoff to the building was required. In the end, the bill was for $1,800. They did not take credit card. No receipt was given to itemize work done. These guys, from Moor Plumbing Solutions, did work hard and got the job done but there was a serious lack of transparency from the very beginning, not to mention a near disaster."

Boiler Repair questions, answered by experts

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
