My family and I would like to thank DNA Clean Sweep Chimney, especially Adam! They were extremely professional and did an amazing job from start to finish. The work was very thorough, never felt rushed, and they truly went above and beyond. Adam was a man of his word -- showed up on time, communicated clearly, and delivered excellent work. He also made sure we knew we could always call with any questions or follow-ups, which we really appreciated. We normally don't leave reviews, but this experience was absolutely worth it. We've had bad experiences with other chimney companies in the past where workers rushed through the job and the quality of work reflected that. This experience was completely different. The quality of work was outstanding, and everything was handled with care and professionalism. We will definitely be recommending them to family and friends with chimneys! Highly recommend! -The Henry Family read more

Five stars for the following reasons: Punctual, professional, efficient, pleasant, and fairly priced. They gave me a window from 10 AM to 1 PM and their office communicated with me the day of via text to let me know my technician would arrive in 20 minutes. He arrived right on time! Communicated expertly. When I called for a quote, Janice was extremely knowledgeable and pleasant, never pushy. The price was fair and reasonable, Amador, the technician was very efficient and took lots of pictures for my summary. Checked all the boxes so I will use them again. read more

Highly recommended! I found DNA on Yelp. I gave them a call and scheduled the first inspection. Provided plenty of photos to show the wear and tear that ultimately became the report and the recommended repairs. Scheduled a follow up visit for the flue repairs. They arrived on time and as scheduled! It was a hot day and he still got up on the roof. They very forthright about the pricing and gave me many options which I appreciated. Very communicative and Great service! I will call them again! Do yourself a favor and get the repairs before the cold/wet weather arrives! read more

What I know about chimneys could fit in a thimble. I was seeking other information and was informed that the Crown on the chimney was deteriorating and they showed me pictures. What was helpful here, after the owner answered 1000 questions, was getting the work done promptly after determining if it even needed to be done.. as I said that was not why I was calling around to begin with. The owner was courteous and patient explaining what my alternatives would be to correct the problem and what could foreseeably be an issue with water leakage inside the house if left without repair. It took hours to repair and seal the chimney. They showed up on time. There was no mess. The prices were fair. read more

I booked an appointment one week ago and their technician (Amador, a great guy :) )showed up exactly when promised. The home office called me 20 minutes prior to make sure I knew he was on the way. We couldn't get to my roof since our house is tall, but Amador tried all options first. He explored my attic, and we even tried to call my neighbors. However since he couldn't safely get to the roof he did the inspection and cleaning from inside. He left 0 dust or mess behind, and gave me great pictures of the chimney interior to validate that it was cleaned. 5/5 would book again. Price was exactly as quoted on the phone, with payment handled through an online invoice read more

This company sent out a professional to fix my fireplace today. He was very thoughtful with his job. Troubleshoot everything to fix the problem. Also very friendly... now my fireplace is working better than before. Thank you for your services read more

DNA cleaned our fireplace and chimney chute at a residential house in Livermore, and everything looks so much cleaner now. Amador was the tech that worked our job, and he was excellent. Thank you for making our fireplace area look so much nicer. read more

I called to request an inspection of a chimney that I wasn't sure of its condition. Janice picked up the phone and was the loveliest person to speak to. She listened to what I was looking for, immediately helped me schedule an appointment, and told me what to expect: they would come out for an inspection first before determining if a cleaning was even necessary. This would ensure that I don't get overcharged for something that is unnecessary. I was originally expecting the following week, but they were able to come immediately the same day. Adam, the owner, came to inspect my chimney. He was extremely personable, knowledgeable, and patient in explaining his findings and recommendations to me. Really appreciate his work and time spent with me. I would highly recommend their service. I will certainly be using them again. Pricing was absolutely reasonable and customer service was top-notch. read more

DNA is a solid and reliable company. Folks are courteous and extremely professional. I've used them over the years and will continue to do so in the future! A+ read more

As a repeat customer DNA provides knowledgeable, friendly, fast service! I'd recommend them over & over! Thank you Adam & crew.

My tech was great, very clean. I got my fireplace cleaned after buying a new apartment. It cost exactly what was quoted on the phone with no extra fees. I will definitely be using them again in the future read more

It was refreshing to finally find someone honest, helpful and a great listener. They were very helpful, supportive and just all around great. Adam was the one helping me he took the time with me and told me not to worry and set my mind at ease. If you need help with your chimney they are definitely the one's to call. read more

We needed a chimney sweep to clean out our chimney since we recently bought our home and the listing agent said the former owners never used the fireplace in the 20 years they lived here. DNA is here in San Leandro and I liked what I was reading in their reviews, so I decided to give them a call. Had to leave a message but they were super responsive and called me right back. They gave their prices upfront for what it would cost for a cleaning and inspection, and came out as soon as they could given that it's fireplace season and they're majorly impacted. The tech came out on time and called before arriving, and got right to work cleaning out the chimney and inspecting it. He found that it's currently unsafe to use due to broken tiles in the chimney that won't effectively keep ash and embers from potentially starting a fire, and quoted us for repair work. We haven't yet had the work done, but I was really pleased with DNA. From start to finish they were professional, responsive, friendly, and transparent, and explained clearly in their report what we need to have fixed to get the fireplace back in working order. They also included photos of our chimney, the damage, and a diagram demonstrating what they'd do to fix the damage. We will likely be going with DNA for the repairs. I'll update this once we do, but the chimney sweep went smoothly and quickly. Very good experience overall. read more

Had our chimney inspected (1920's home) then followed the recommendation to have the mortar replaced and a new flu system built. Found the work very expensive and chimney doesn't work as well as it used to. Also had damage to roof tile. read more

Awesome company! I had a hard time getting a hold of a service provider to check, clean and repair any possible issues with my fireplace. DNA called me back right away and had someone out just a few days later. Rick Fisher was super friendly, knowledgeable and speedy when he arrived at my house. I enjoyed the whole experience from the quick reply by phone to the actual inspection. I also appreciate that Rick went the extra mile to explain to me how to use the fireplace because I have never had one before. It sounds simple but the tips he provided on how to make the best fire and even where to get wood were things I appreciate hearing from a professional when there is so much mixed information online. read more

I had DNA come out to do work on my chimney. My experience with them was very positive. Very clean work compared to others I have used. If you need work done, I highly recommend them. They were very professional and polite. read more

TIS the season to get warm and cozy over a fire! I scheduled these guys for a fireplace inspection and potential cleaning and had a great experience! The people I spoke with over the phone with questions and all scheduling needs were very friendly and helpful. First off, I have never used my fireplace and I've lived in my place for 5 years! I always thought it looked decorative, and I was intimidated because it's a wood-burning fireplace - which I've never had before. I live in a condo building. Two guys came by and in total they were in and out in 1 hour! They spent that time doing a thorough inspection. They said I didn't need a cleaning - which I really appreciated, as this was proof they're not trying to upsell things that people don't need! The techs wore masks and social distanced, and I kept the balcony door open. Overall it felt pretty safe. Finally, they just mentioned that all I needed was to get a fireproof hearth mat and I would be good to go to start having fires in my fireplace! I ordered one online immediately. I asked a few other questions about wood-burning fireplaces as well and they didn't mind at all. Overall, great service! Loved all the crew I interacted with! I had my appointment last month, on 11/26, and I believe I called two weeks prior to try to get an appointment. These guys book up, especially during the cold weather weeks! If you're due for an inspection next year, get it done early (Summer or Fall?) to avoid a wait for an appointment (before it gets cold)! Finally, payment was taken over the phone after the appointment, so that was easy and contactless. read more

DNA Chimney was able to clean my chimney and quickly add a damper within a week! I was having the hardest time finding a company to make sure the fireplace would be safe to use for the winter. Also good to note they did work in early spring and wasn't able to use the chimney for about 8-10 weeks to let the repairs settle (makes sense) but good to be aware of if you want to use your fireplace for an event. They were prompt, reasonably priced, and very friendly! Thank you DNA! read more

These guys did a great job cleaning up the chimney did inform me of all the problems my chimney had since it's an older house Adam was great took pictures and emailed afterwards of the problem areas in the . I recommend these guys are very professional I chosen because I live in San Lorenzo and there were also a local recommended company. They were really good about cleaning out the creosote which in my case had built up for years. read more

Adam from DNA was extremely helpful & responding to trouble shooting by phone today! I used DNA's clean sweep chimney service for an inspection clean & start-up & they were undeniably the absolute best service company out there! read more

I realized that I had not written a review of my awful experience with Adam and DNA. So here it is. I calledand requested that they clean & inspect my chimney. Adam called We talked. He sent the quote and I accepted. I had not used it in over 10 years. And before that, used the wax logs. I wanted to convert it to gas. He sent a worker over. He cleaned it out and inspected it. It needed to be repaired. They repaired it. So far so good. I had them install the new gas log set. It worked fine. That is when things went BAD. And I Mean VERY VERY Bad. There was SOOT all over the house. A BLACK LAYER of soot everywhere. I had to get the house, rugs, floors and curtains cleaned. And cleaned. And cleaned. What a BIG MESS. (Did they ever offer to pay for any of this? NO!) I Called Adam. Told him what happened. He sent his worker out. Guess what. He cleaned the chimney AGAIN. This entire sequence happened a total of 4 times. Not One. Not 2 Not 3 But 4 Times. I have attached some pics of the soot after cleaning. In total Disgust, I called JEFF @ PENINSULA CHIMNEY. He came over and verified everything was done correctly. He made the suggestion to add TEMPERED glass on the doors to the fireplace which would keep to the soot, THANK YOU JEFF. Summary: If you want a big mess in your house, call DNA. They do not know how to clean a chimney properly. read more

DNA's Clean Sweep did a fantastic job with my chimney cleaning, sealing and new cap damper. They were prompt, professional, and thorough. As a family business serving the Bay Area for over 20 years, they clearly know what they're doing! Fair prices and excellent service!

I got my chimney cleaned by a screen/chimney combo company (not DNA) when I moved into my house. Little did I know, they also did a "full inspection" which resulted in an $8k quote. It didn't smell right to me and so I called DNA for a second opinion. I spoke with Adam for 10 min and he patiently reviewed the other company's quote and report w me. He agreed that it didn't sound like an honest quote and offered to send someone out for free to take a second look. DNA came out on time and did their own inspection. The tech, Rick, was very nice and very honest. The end result- my chimney needed No Repairs!!!! The tech recommended some maintenance that I could do on my own. This company could have quoted me $3k worth of work and been my hero after the last company, but they have something called integrity! Thank you DNA!!!! read more

Friendly, knowledgeable, cleaned and inspected our chimney: we were able to use it for the holidays!

We've used DNA's cleaning and chimney repair services for the last 10 years and they always do a fantastic job. We recently had an issue with some smoke in our attic that we thought was caused by the fact that it needing resealing. After the resealing was done, the issue wasn't fixed. We called them back to ask what we should do and they came back out right away free of charge. They looked everywhere until they found the cause (a small issue under the chimney cap) and fixed it right then. I absolutely recommend them for any fireplace concerns you have. read more

The service and staff was excellent. Our chimney had not been cleaned in a very long time and clearly needed it. They informed us that they first do an inspection and then cleaning once they confirm that chimney is in good health and in fact needs the cleaning. Two separate services and were reasonably priced. The service agent, Rick, was professional, very informative, and a pleasure to talk with. He kept us informed as to the process and status every step of the way. He even provided some tips and suggestions to help us in the future. Despite the potential mess, the entire space around the fireplace and paths through the house were completely clean. The entire service took roughly an hour. I highly recommend the company and will use them again in the future for any fireplace needs. read more

After an extensive search and calling several people for estimates on Friday, we decided to go with DNA. Rick came by yesterday and was really great to work with. He was honest, cleaned our chimney without making a mess, and gave an extensive report on his inspection (pdf with pictures emailed). He made sure everything was safe and said for some things he could charge x if we wanted him to do it, or spend only x if my fiancé did it himself. We will definitely have Rick come back to maintain our fireplace annually. We trust him, his expertise, and recommendations. read more

Beyond my expectations!!! Someone who actually answers the phone and books your appointment when you call. Received quote when I made the appointment and was provided information on what would be performed the day if the appointment. Very happy to get an appointment within two weeks as I understand it's a busy time of year. They give a one hour window for arrival which is super helpful. Technician called 30 minutes prior to arrival. They performed their inspection and cleaning and it took approximately one hour. Technician was super friendly, left not one speck of dust or dirt and showed respect for our home. Our chimney was long overdue - like 20 years for a cleaning. Was charged exactly what I was quoted and I can't tell you the improvement in the air quality now in our house as we are having our first fire if the season. Highly recommend for quality service for a very fair price. read more

These folks installed a metal chimney liner and a rotating top on our chimney. When there was a small problem with the installation, the owner came out within a couple days and fixed it.

Had arranged Inspection and Cleaning a week prior. On the day of appointment, Bryce called and gave me an ETA. He arrived early. He gave a run down on what they were going to do. A two man team. They set up and did a cleaning. After he provided pictures of the inside of the chimney and suggested some work that would probably need to be done for safety issues. A few days later I received a report of the work done and an estimate for future repairs. Overall, I was pleased with service. Very punctual, friendly, and clear communication of the work they were doing. read more

There was a wait to have my dryer vent cleaned out but well worth it. The tech did the job efficiently and hooked the dryer back up so that it was ready for use. Their price was very affordable. Other estimates I got were outrageous. Totally happy with their work and orice. read more

Got a decent referral, they actually did the Level II inspection before I moved in. Once I began looking into repairs, for whatever reason I cannot get a call back. Not sure if the company is closed or what not but no call back after ten calls, five messages over the course of two weeks. pretty disappointed. going to move onto the next company. read more
