We are very impressed with Certech. Sean was very professional, knowledgeable and did a very thorough and clean job. While addressing our rat problems, he also pointed out our ant infestation and addressed the problem on the spot. As a bonus, Sean also came prepared with booties and wore them over his shoes while doing work inside our house. We will definitely use Certech again and will be recommending them to all our friends. read more

I highly recommend Certech. We had a huge rat problem and the owner Justin personally came over to my house on a weekend and took care of it in just a few visits. Great service, great prices, very professional. Thank you! read more

Very prompt. Very professional. Really competitive on prices. Got the job done well and fast. Will hire again.

We used Certech to remove a wasp nest in front of the house and they were simply great! Quick response, and Fermin came over speedily and resolved the issue efficiently. Highly recommended. Thank you guys. read more

Smart, capable, polite, efficient, and well versed in multiple modes of pest control. The "Long and Short of it" is that Certech effectively eliminated our Bed Bug problem. I have run camps for children where we needed to eradicate bed bugs. Utilizing sprays and powder applications did not eradicate the bugs. It wasn't until we utilized heat that the bedbugs were eliminated. Certech does heat eradication of bed bugs; however, the size and shape of our home did not lend itself easily to heating. So, I went in search of a company versed in the use of Vikane gas to treat bed bugs. Certech is one of the only Bay Area companies capable of doing the Vikane treatment (at a dose 3 times the treatment for termites) followed by topical application of material at critical sites in the home (for any potentially remaining bed bug eggs that may not have died from the gas). Needless to say, Justin Sinclair and his team at Certech efficiently tented our home, applied the Vikane, followed up with topical applications, and made our lives good....and bedbug free. Oh, and they guaranteed the treatment for 90 days (more than any other company I found). Bravo Certech! In fact, we signed up for their every 2 month maintenance service because of their capable approach. 5 stars EARNED! read more

What a joke, I reached out 4x asking for a quote once in email, which I was responded to by asking for my number so someone could call me back. Then i have called 3x and given all the same info and been told someone will call you right back...this started on June 22nd it's been over a month trying to just get ahold of someone. Don't waste your time trying to get in touch with someone for service no one takes the time to call back or follow up with new potential clients. read more

I purposely looked for local companies when I found out I needed termite treatment. Justin answered all my questions (options, toxicity concern, etc.) while I was comparing all the quotes I got. I chose Certech for their knowledge, competitive quote, warranty and availability. read more

Prompt, friendly and they get the job done! After renovations we had a pretty bad ant situation. Especially worrying with our little one. Shawn came out and did the job very quickly. It's been 11 months and we haven't seen an ant since. We maintain quarterly spraying outside the house with Certech as well. Very happy customers. Thanks, Shawn! read more

Sean is the man. He came out with less than 24 hrs notice and fearlessly took care of our wasp nest issue without any chemicals. He was extremely knowledgeable and patient with the many questions and concerns I had. Completed the job effectively and thoroughly with consideration for our familys needs. Cleaned up the area better than he found it. Very professional and exceptional service. Can't say enough about the guy. As long we get Sean, Certech is our go to provider for bug issues. read more

Okay so my worst nightmare happened.... an animal of some sort has taken over my garage and taken away my sanity! I was freaking out (k still might be but ignore that) and Certech was able to come out immediately and figure out what is taking up squatter rights in my garage. Sean has been doing the work on our house and filling all the holes and gaps that I didn't even realize a rat could get through! Sean came back out to check on the traps and tell us what to take out of the garage because now since all the holes are plugged up we have this thing cornered! Progress is progress and I'm so thankful for how professional and helpful this company is! Thank you Certech and Sean and when this thing is caught in a trap, yes I will be hiding until it is taken away lol read more

Justin was great! Was able to make it on site on the same day that I contacted him. Very friendly and professional with reasonable rates. I will be a future customer. read more

Sean was a really nice guy, super thorough, and willing to go the extra mile to get rid of the numerous ants swarming all over our house. Certech responded to our quote request almost immediately and arrived less than 24 hours later to help us out. We are so grateful! read more

Justin and his team did an awesome job, Can't complain about anything, Prompt, on time, ahead of schedule! Have and will continue to recommend to anyone in need of their work! Thanks for Making this experience as pain free as you did. From Heather and Rod Baker read more

Certech has taken care of our pest concerns for about 3 years. We've had rodent issues in the house and garage. We've had ant issues and spider infestations outside. They come every couple months to routinely wipe away spider webs, spray for insects, and handle any additional issues we've had, including rodents and ants. I can trust that if an issue arises, that they will take care of it, usually within a week if it's outside our regularly scheduled appointments. We have a play structure in our backyard that they wipe spiders off of and spray (we keep our kids off the structure for a few days after they spray). Our kids are able to fully enjoy their outdoor backyard space because they don't have to worry about spiders and spiderwebs. I really like the owner and every person that has been assigned to manage our pest problems. Sean has been helping us out for over a year. He is very friendly, informative, and works really hard--does a great job to mitigate pest issues. Certech delivers a reliably great service. I highly recommend. read more

Sean came out to the house to address a cockroach problem and I couldn't have been more pleased with the service he provided. Very knowledgeable and thorough. He even took care of our spider problem, closed up a small hole to reduce the chance of rodents in the future, and removed a bee hive. Thanks Sean!! read more

We had a problem with mice and Sean did a great job to help us take care of it. He was responsive and thorough in inspecting the house for entry points, sealing off any possible entrances, and setting traps after the work was done. He also did a great job cleaning out the area in our house where the mice had been most frequently. Sean came back to the house to make sure everything is working properly and we are happy with the work he did. read more

Very professional and timely. With our potential mouse problem, he showed me areas where the critters may have been getting in. It was nice to have those holes closed up within a few days. Would call again if needed, but hope we don't need them again. :) read more

I was recommended to Certech by the agent who helped me purchase my home. The agent told me that Certech was reliable and could be trusted to give straight answers/opinions. I couldn't agree more based on my experience. I needed someone to take a look at some drywood termite damage. Justin, the owner, came out and took a look. Was very impressed with his knowledge and thoroughness. I decided to have Certech do a full pest inspection (as the prior inspection I had done had missed certain things). Justin came out and did a thorough inspection of the property, gave me the full scope of treatment and repair options, and gave me his professional opinion on how we should proceed. Prices were extremely reasonable. I am the type of person who always has a lot of questions -- especially where (as here) I have little knowledge. Justin was extremely responsive and patient with all of my questions. I will be using Certech for the treatment and repairs as well as having regular inspections done as a preventative. If you have pest problems (or are concerned you do), I highly recommend Certech. read more

Had a bed bug problem that was treated by Certech over a week ago. They are very responsive, and the owner Justin answers questions personally. It was easy to schedule with them, and Justin explained everything in detail and helped us with the preparation process. Once here, they were minimally disruptive. So far we appear to be pest fee, plus worst case scenario if the infestation returns there is a 90-day included warranty. Bottom line: Certech is responsive, available, gives results, works around your busy schedule, charges a reasonable price, and has a generous warranty of 90 days. I had some initial concerns given the smaller number of reviews on Yelp, but Justin has been in the business for a few decades, and he started this company only in 2016. I would strongly recommend giving them a call and I think the uniformly positive reviews here so far pretty much guarantees a good experience! read more

Wow! Their customer service was amazing. They came out on Monday to review the termite damage and determine what type of termite it was and recommend a treatment. Justine,the owner, came himself! He was early, very knowledgeable and courteous. He spent time educating me, showing me additional damage which I had not observed and provided me with a very reasonable quote. He was out on Wednesday and did an amazing job. I hired him to also fumigate our house. He spent almost 3 hours onsite. The chemicals did not smell at all, and he did not leave a mess. He even pointed out other areas of concerned, sprayed them as well, and refused to charge extra. I would use him again and I would happily recommend him! read more

Our house was infested with fleas from our cats, they came out and with just one treatment totally rid our house of fleas. They responded quickly and were very courteous. Larry Y read more

I highly recommend Colby from Certech. We have a newborn baby and a cat. We moved into a condo to have more room for the baby-and then found out that the place is great but had fleas from a previous tenant's pet. I comparison shopped, and Certech had a solid warranty and deal. We had a mixup and couldn't board our cat during the extermination appointment, and Colby kindly rescheduled after waiting for confirmation about the cat boarding. Then he came again the following week. During the second visit-our newborn woke up from a nap-screaming and crying from wanting to sleep longer and was hungry. Colby patiently waited for us to evacuate our home while we got baby and the place ready. He stood outside for a good half hour, and then told us that he understood that a baby changes things and not to worry about it. Then we forgot something I needed, and ran back in. Colby later texted me confirmation that the process was complete, and that we had a 90 day warranty. Justin and Colby both assured us that our precious baby and pet would be safe after the pesticides dried. It was very important that the chemicals not harm our delicate human and fur babies! Thank you, Colby for your patience, kindness, and understanding. read more

This company is awesome. We have had a rat problem for about 2 months. We tried every trick in the book, but didn't work...still had rats. Somehow the rats were getting into attic and this was incredibly annoying. We called and Justin was at our house in 2 hours. He explained the process of how rats do their thing, and then went to work. He was able to find a few spots where the rats clearly entered our attic space. He sealed them up and set traps in attic and crawlspace. He did all of this in approx. 1.5 hours. Needless to say, we no longer have a rat problem. Overall, incredibly prompt service, resolved the issue and excellent attitude. More than anything, more reasonable pricing then other firms we researched. read more

Justin is so pleasant and so professional, and everything that he does is done with a smile. He is thorough, and he really knows and understands his field. He walked around the perimeter of the house and garage with me and explained exactly where the rats/mice could be getting in. His availability was great, which is very important when you want pests gone fast! He is easy-going, kind, and fair :) read more

Gareth just completed the project here in my home that required extensive surveilling over the course of the past month because of rats. He did an excellent, thorough job: wired up holes to block the rats reentry; bating and positioning traps and then coming by on a weekly basis to check the traps and dispose of any dead rats (2). The last visit, today, he helped educate how to prevent a reoccurrence. Highly recommended; and appreciate my neighbor's referral who also received excellent service from Gareth and Certech. read more

Not happy with Certech. Justin paid no attention to what I wanted and what we agreed on. I called Justin Sinclaire with my gopher problem on Wednesday. He said baiting is the most reasonable option. After probing for the trapping method, I found out that was just as reasonable. He came out put something in some holes, and it appeared he was training a new guy, my neighbor said. I came home to no traps. He said he'd return to trap, however, this is Sunday, and we not only have a new mound, we have a skunk digging up our yard for the gopher. This review should not be a surprise to you, Justin. I told you how disappointed I was when we talked. I only hope that the new guy doesn't learn to disregard his customers, too. You get one star for being here on Friday, the only thing done properly. read more

This company has done a fantastic job for me. They have been very quick when needed and complete a thorough job. I will defiantly call them again when I need pest services. read more

Great customer service on the initial outreach. Owner answered all of my questions on the bird nest removal and the elimination of the bird mites. Quote for the job was very reasonable. The work done on the day of the job (which happened in a couple of days but could have been the next day) was exceptional. Extreme care was taken to make sure everything was done (and nothing was moving/living) and that I was satisfied with the work, which I was. Great job, Certech!!! read more

Excellent and prompt service that addressed my squirrel problems. Way to go!

I contacted Certech for a Gopher problem in my newly completed back yard lawn and the service Justin gave was clear, honest, and quick. He told me the problem would return due to the area that I lived and gave me a 3 month guarantee. Service was expensive, but in line with other companies in the area. The difference was he quick to respond, educated me and was professional. read more

I discovered a bad rat infection the day before company was arriving from abroad. I called several exterminator services; Certech was the quickest to respond, and they came out that very afternoon. Their technician, Gareth, was like a detective, searching out ways the rats were getting in, then closing them up with netting or concrete! He came back every other day for several weeks, nearly a month, checking the traps he had set (no poison!) and looking for signs of more possible entrypoints to close up. I trust him completely and give Certech, and Gareth, my highest possible recommendation. Thank you, Gareth. You are such a professional young man, expert in what you do, personable in your communication style, and a genuine point for pride. This review is from Lee Ann, on hill behind the Claremont hotel in Berkeley read more

Recently my house was infested with ants and they just came out of nowhere. My friend told me about CerTech and I called talked to the Justin. He explained what he is going to do and told me he has the 90day guarantee. He came and set the traps throughout the house and in the garage and outside the house. That evening I saw trail of ants in front of the garage, in the garage and on one of the windows inside the house. I text Justin and he said just leave them alone to feed on the bait. Sure enough the next morning they almost disappeared completely......great job Justin! read more

Great service, responsive, thorough. Justin was friendly, helped out a great deal, took care of interior and exterior service promptly. They work with HOAs as well. read more

These folks our great, Garath, our tech was responsive and efficient. They're a locally owned company that is so much better than those big, national chains. If the need ever arises again we would use Certech in a flash. read more

Certech was terrific dealing with rats in the house (fortunately only in the garage and the basement, not the kitchen!), after all the winter rain. I called them on a Thu, and they were here on Fri. They blocked up all the possible entry holes, placed traps (no poison), and returned in a week to remove the traps. I'd recommend them to anyone. read more

Bed bugs! Yes I discovered bed bugs just as the sale of my Home was in escrow. While this was a very stressful situation Justin came out to assess the situation. He was knowledgeable, professional and immediately took control and resolved the situation in a timely manner. read more

I had a very serious problem with tiny red spider mites. I couldn't find anyone that could get rid of them. I finally contacted Justin, he spent the time researching these mites and was able to totally eradicate them. couldn't be happier with the service. read more

These guys are great. After our house was initially treated we noticed we still had some insects near the front door. I called Certech and they came out the next day which was Sunday! Great customer service. read more
