Was very responsive and made me an appointment quickly. Then when he arrived and realized the problem was an outlet reset button, barely charged us for the visit. Will be calling him if we need an electrician in the future. read more

OMG, I had the receptacles in my kitchen not working, and David (over the phone!) told me to check the GFCI, and sure enough that worked. Thanks David! read more

I called Tinpa based on my Yelp search for Alameda electrician, and I definitely lucked out on this one! 2 kindly folks showed up at my house that same evening to fix the 75-year old switch that had finally died... sweet and courteous family service, extremely good rates, and the chance to support local Alameda business! Highly recommended. read more

Tinpa Electric is Wei Guo (David) Zeng: He is the electrician you want working on a home you care for. David is thorough, efficient, knowledgeable, professional, accommodating and friendly. I have a nearly 100-year-old Craftsman in Alameda with a kitchen remodel just completed. I brought in David based on other Yelp reviews and a call to one of his references. David has easily met and exceeded my expectations. He moved and upgraded the service panel, added new electric receptacles, rewired old knob and tube wiring for light fixtures, brought in electricity and lighting to a stand-alone garage, wired the small basement for a washer / dryer and new wiring needed for the kitchen... all with no problems regarding permit requirements (He's licensed in the state of California). When I was faced with options, David patiently explained the choices. At the end of the job, David asked me to rate his performance on an A to F scale (What contractor does this?). He said he wanted to learn how he could do his job better. I said, "A+ squared. Excellent work. Sorry, I can't help you get any better than you already are." Hire David Zeng. In this review the accolades are deserved. His rates are VERY reasonable and he's great at what he does. read more

Second time customer...David is just fantastic! He did a wonderful job replacing the breaker box in my home and I would call him back without hesitation for any electrical work. Most highly recommended! read more

David is awesome! We had no electricity in the bedroom, the breaker tripped and couldn't be reset and we couldn't figure out why. I resolved myself to having to wait for several days for an electrician, if we could get one to show up at all. Everyone seems to be so busy these days, they turn away work. My husband left a voicemail for David in the morning and he called me later that same afternoon and came right over. He sorted out the problem quickly, showed me exactly what was going on, fixed it and charged a very reasonable rate. I'll always call David for any electrical work! read more

David is fantastic! He recently rewired our entire 1908 house, which still had the knob and tube wiring. He's incredibly detailed and thorough, and made sure to let us know if he had any concerns or if something we asked for might not be up to code (we passed with flying colors). He was also very patient with answering all of my questions, and scheduling his work around some other work we were doing at the house. I would definitely look to David if we have more electrical work come up. read more

Oh my god, yes, in agreement with all the other reviews. I picked these guys due to all the yelp raves. David and Helen (and family member helpers) rewired 2/3 of our entire house (1925 craftsmen with lathe and plaster walls and knob and tube wiring- definitely a complicated job) and installed new 200A service panel, for seriously 1/2 to 1/3 of 4-5 other quotes for the same job from many other reputable area electricians. I did my homework. To semi-quote them (I agree with other review of minor language/communication barriers, but which are easily worked through), they are pairing low hourly rates (like 60/hr!) with solid hard work, high quality, and friendly responsive service in order to build their business and establish a solid clientel (business only 2 years old here in states). Take advantage now before they realize how much more they are worth and raise their rates accordingly. Passed inspections no problem. David really does know his stuff. All throughout the process his knowledge of most current electrical code checked out (I have a family member who is a building inspector code-enforcement officer). And once again, these people are really nice! Everything you want in someone to contract to come work on your house. Couple other small things, they are not really pet people so a little afraid of our dogs but tolerated them well. And since David does such quality work and is a family run outfit, bigger and more complicated jobs may take a little longer so be patient with time-frame from start to finish. read more

We have used David for projects large and small, from fixing an electric outlet to installing hot tub wiring to recently upgrading our electric service to 200 amps with new box, etc. David is extremely responsive and very knowledgeable, creative, honest and professional. He is also very efficient and works extremely hard, and his pricing is quite reasonable for a top notch electrician. David has my strongest recommendation. I really appreciate his versatility and willingness to handle all sorts of electrical jobs...really makes the decision easy when it comes to decide who to call for an electrical issue! We look forward to working with David on future projects. read more

I figured with such a spotless rating on Yelp I couldn't go wrong. I wasn't disappointed. David is friendly, punctual, affordable and does quality work. He installed two new outlets, troubleshot another and brought us up to code in a couple areas. He even straightened up our wiring around the panel. All for a very good price. Believe the reviews, he's that good. read more

OMG!!! Wow, what can't I say. This husband and wife Team David and Helen are awesome! I am so thankful for Yelp. I am currently remodeling my fathers house in Oakland which is very old and without any upgrades. I called and spoke with David and he accommodated me many of times considering I live is So. CA and fly up every other weekend for this huge project. David was efficient and timely each time we spoke or met. He sketched out my dads layout and what I was asking for. We came up with a price and two days later David and his team came in on white horses saved the day and did a fabulous job on my dad house. I would use and also refer them to anyone. As a matter of fact I will be contacting him this week regarding recessed lighting in the bathroom and possible sconces. Please hire he and his wife they are a great team. read more

David upgraded our office electrical when we were on vacation. He did great work, left the place spotless, was very reasonable on his prices. David is a gentleman, always leaves his shoes outside, is a thorough communicator, lets you know what you need to know about what he is doing. Couldn't recommend him more! Thanks David, laurie and Mike in Alameda read more

Okay, maybe just a tenth of a star reduction for some very minor lingual mishaps. But these guys are just as good as the reviews stated and I couldn't have been more pleased with their ability to work within our budgetary constraints and the idiosyncrasies of our home. We'd just gotten a secondhand hot tub spa situated in our back yard and wanted the electrical hookup installed before my birthday weekend without breaking the bank. Their schedule was full but if we could manage a minor task in advance of their arrival, they'd have us up and running by doing a couple of hours after dinner. God bless 'em! I spent my birthday in warm, jet-swirled waters. And I certainly won't have to spend an hour researching who my next electrical contractor will be when I need someone; David and Helen are our new go-to guys! read more

We can't recommend David and his wife enough for their professionalism and honesty. The do great work and follow up as well.

I am visiting my family in Alameda and helping to get some work done around the house. David and his helper, Kasey, did an excellent job for us. They removed our old ceiling fan, assembled the new one and relocated the electrical service box. David made sure the new fan was balanced and stable even at its highest speed and that the light worked from both the switch and the pull chain. All for a very good price and without a speck of sheet-rock left behind! David came when he said he would, did a great job and was remarkable responsible about minimizing the mess. We will call him first for anything electrical in the future! read more

David is unbelievable. He's very helpful. He's knowledgeable and can visualize fixes that you don't see right away. You want your wires to come into your house and be hidden. He can do it. If he has to put a hole in your wall, he can patch it. He's a wealth of knowledge and I'm glad that he's available to us in Alameda. I would definitely use him again. read more

Tldr: honest, great work and fair price. I had power out in half my house after flicking on switch in bathroom. Checked the breakers and they were fine, but smelled burned metal. Ok, I thought maybe bad switch, changed that and gfi next to it, still no go. They had power to outlet but nothing plugged in works. Time to call the pros. Called David and he came next day on time! He found one problem very quickly (melted wire in door bell transformer close to fuse box, thus the burned smell) they fixed power to one room. still no power in another part of house. He and his helper checked all the outlets and switches in affected areas. They eventually found the other issue, fixed that and other wiring hazards. I even learned a lot from David, he was friendly and genuinely believes in SAFE and quality work. He even pointed out problems in the basic work that I did, so I could do safer replacements myself. How cool is that? All in all, it was a pleasure to have David work and I will definitely use him again. read more

Nice, knowledgable & very reasonable. Also called Sunday morning was at our house that afternoon and fixed the problem in less than an hour. I will def. Use David again! read more

This post is long overdue: Picture it, Christmas Eve in the Bay, Dec 24, 2014. Christmas eve and the electricity went out in half the house. I am in the middle of cooking part of Christmas dinner and the blender stops, Donny Hathaway stop serenading me, stove, microwave, home alarm, etc all dead. David came over and fixed the problem at a reasonable price. Now, I'm not saying it didn't hurt--I don't like unplanned/necessary expenditures or spending money to fix problems, but Tinpa was less expensive than the other 2 businesses I called and he didn't charge me extra for coming out on Christmas Eve. David Explained the problem thoroughly, explained why he had to replace all breakers and the panel (oh I'm feeling the pain again - I really wanted to spend that money on a new bag). Sign... well problem was fixed, Christmas dinner was scrumptious and all is still well. Thanks David! read more

I couldn't agree more with all the other postings. Tinpa Electrical should get 6 stars! We had quotes from other electricians who all told us they would need to rip out part of the walls to install lights on the ceiling and wanted twice as much. Then, thanks to Yelp, we called Tinpa Electrical and he was able to do the work without any unnecessary cutting and patching. They work hard, get the job done fast and offer the best prices. I highly recommend Tinpa. read more

We had David install some new recessed and under cabinet lighting in our kitchen and we were so pleased with the work he did. He advised us on the right type lighting to buy and was incredibly patient with sourcing the under cabinet LEDs. Top notch, very professional work. read more

Needed a chandelier type light installed in a high ceiling living room where none existed before. David was able to install new wiring and my light fixture for a very reasonable price. His work is meticulous and clean. He delivered exactly what he promised, showed up on time, and completed the job quickly. I was so pleased with the work and his prices that I went ahead and had him install recessed lighting in my family room. But here's why he gets a 5 star rated from me: While turning off the power to do the living room from the control panel, David noticed an improperly installed breaker. He fixed it for no additional cost. I had failed to purchase the correct dimmer switch for the recessed lighting project. David's wife, without hesitation, went out and got the right one for me saving me the hassle. I will not hesitate to call Tinpa Electrical for all my future electical needs. read more

David & his wife Helen came by this morning to my house to resolve my electrical problem. As always he was very personable, professional,educational and patient. He was very busy with various clients, but he was able to me between his large projects. I have no problems in recommending him to others. However, please note he is a small business. Therefore, you have to some patience in waiting to be serviced. Thanks to a job well done! read more

David is fantastic... He did all my electrical work during the remodel of my house, which was built in 1894. He saved my life and a lot of money. More importantly I passed all inspections in Alameda without any issue. He knows all the building codes related to the his field and will always provide you with the best and cost effective solution. He is very meticulous, affordable, hard-worker, professional, always on-time and never came up with any change order. As a homeowner it has been a pleasure working with him and I wish his company success. I recommend 100% this company. Franck read more

If I could give 10 stars, I would! David is just amazing. He is hardworking, honest, and humble. He knows his stuff and he gets things done so well. I wanted to rewire and install tracklighting in my living room and family room. David came after long day of work and accomodated me into his schedule and he did it all. He also charges really reasonable amount, that I am just really impressed. And he works really hard! I am going to David for all my electrical issues from now on. read more

I called David from Tinpa after my power had been out for over 24 hours. PG&E was not being responsive. He came over within a couple of hours and immediately fixed my problem. He was the most affordable electrician (on an hourly basis) of the three that I had called that day, AND he ended up providing a discount because it was so easy for him to fix my problem! He took the time to explain what had happened, and what I need to do in the future in the event that I had another electrical outage (that was my doing and not necessarily a result of a larger power outage). I also happened to have two outlets that needed fixing, which he did within half an hour. I would definitely call David again if I need an electrician! read more

I can't recommend Tinpa Electrical enough! We called on a Monday, David and his wife Helen came out to give us a quote a day later and did the work the following Tuesday. They spent a whole day on our small projects and really took their time to make sure it was done right. They were very very nice and we felt that our house was in good hands. We will definitely use them again (which we know we will need to do)! Thank you David and Helen, you were awesome!!! :) read more

I haven't logged into yelp in a long time, but after the awesome service that David and his wife provided I wanted to make sure that they got the props they deserve! Had them come out on a few occasions and they've always been prompt, figured out the issue quickly and had very reasonable rates. Highly recommend the service! read more

David is very professional, prompt, efficient and good at his trade. He came to my loft to fix several issues. He was effective, fast and reasonably priced. I am so thankful to have my electrical issues resolved. I would definitely recommend David and I will be sure to call him should I have any future issues. read more

Responsive, helpful, capable, reasonable. Installed an outdoor outlet for me by connecting into an indoor outlet on the other side of the wall. Gave me options on the different types, including benefits of each. Made a decision, and they had it done in about one hour. Very pleasant, very polite! read more

David redid electrical wiring in my 1974 house and upgraded the circuit board to modern standards. He fixed problem with weekly short circuits and installed outlet for quickly charging our electric car. He did not recommend more work than we needed and charged a fair price. I highly recommend! read more

My wife and I recently purchased a home in Alameda. We had a fan and light fixture that wasn't working and could not find anyone to look at it for us. We got on Yelp and saw Tinpa Electrical. We spoke to David and he stopped by and diagnosed the problem on the day we called. The next morning he brought over the parts and got everything working perfectly. He was very neat and professional and did a good job of explaining how to use the new controller he installed. The work was done promptly and the price was fair. I would give Tinpa the highest recommendation and will use them for any future electrical work. Sal read more

David is great, super responsive and on top of things! Also, super fast turnaround and honest pricing. Thank you!

David was a phenomenal contractor, the best I have ever used, did a fantastic job with the panel and kitchen outlets to bring them up to code. Inspector commented on how clean his installation was and that he always sees great work whenever he checks David's work. read more

David is a kind and honest person. He is a very skilled electrician. He explained what the issue was and showed me what the problem was before beginning work. He also cleaned up after he was done and left the place in original condition. I recommend his work to potential customers. read more

Excellent service! Responsive professional. Courteous and knowledgable! Provided top level service, at a reasonable price, and was able ot squeeze me in despite a very busy schedule! Thanks so much!!! read more

What can I say about David from Tinpa Electrical that is not positive? David is fabulous! We moved into our townhouse in 2013, and David has installed 1 chandelier, and 3 ceiling fixtures for us. Also, he has come out on short notice several times to fix burned out sockets, and other electrical issues we've had. Most recently, our kitchen lighting was flickering and went out completely. I contacted David, and we scheduled an appt for 2 days later (he's busy). However, he contacted my the next day and stated that he could come that day. He diagnosed the situation and fixed it. Not only is David a competent electrician, he is also a humble, kind, and respectful person. I would highly recommend David, and I will recommend him to all of my friends. read more

Tinpa Electric is simply the best. I hired David to do the complete electrical for a ground up new residence and his work product is beautiful. He did the rough in electrical, the finish electrical, telephone, cable, CAT5 internet wiring, and audio/video wiring for the whole house. He is very efficient, and on time, working this big project into his schedule without causing any delays for other subcontractors. That's extremely valuable when building a house. The thing that strikes me the most is that he really takes the time to think things through BEFORE starting the project. He thinks out of the box and visualizes functionality. While we started the rough in work, he would comment about changing the location of various outlets and switches so that the locations would make sense when actually using the switches or plugs. He and his wonderful wife, Helen, recommended dimmers, LED lighting, and placement which resulted in a very beautiful and functional layout. Most of the time, contractors will follow your plans exactly and then charge you for change orders afterwards because the problems arise after the work is done. David really thinks through the changes for you BEFORE you realize you will need them later on. I interviewed at least 3-4 contractors for every area of the house, plumbing, electrical, heating, roofing, painters, etc and Tinpa Electric is the one company that stands out. My general contractor liked him so much that he started to recommend him as well. David has also done commercial work as well as residential work for me and the inspections pass with no problem. If you want a family run, honest, reliable, efficient and to top it off a really smart guy, call Tinpa Electric. read more

A+++ We had an unexpected electrical issue come up in our 1923 home. I called Tinpa Electrical and they helped me right away! He was very professional, kind, and quick! He knew what he was doing, and we felt we were in very good hands. He was even sweet with our daughter and cats! What we were expecting to be a huge bill ended up being super cost effective, and the problem is 100% solved. We will absolutely call Tinpa if we ever need electrical help again! read more

David has done electrical work for us many times in Alameda. He responds quickly when we contact him and gives us advice on what materials (canned lights, etc.) we will need. He will buy them & bring them with him or let us buy them on our own & have them ready. He is always courteous and professional. David does great electrical work and advises us on the different options we have available. He prices are reasonable & he always explains what he is charging us for. I can't say enough good things about him, but perhaps the thing I love the most is he cleans up any mess that is created from drilling, etc. and is very respectful to not scratch floors, etc. Highly recommended. read more
