My wife and I have been very happy with Certech's service. A rodent had made its way into the crawl space under the house, and subsequently died. The smell was getting to be too much. Certech's service technician, Jose, was extremely helpful and friendly, on time, and quickly solved our rodent problem, as well as shoring up the points of entry so it wouldn't happen again. We are very happy to do business with Certech and will continue to do so in the future. read more

Also see my earlier review 5 Star on work Certech for me with an Ant problem I was not able to solve myself. Unfortunately, I had another occasion recently to need pest control services in connection with a rat problem I was having. We had used a different service provider 9 months or so earlier and had the problem under control until it wasn't again! The earlier exclusion work that had been performed had been compromised. I had found the likely place they were getting in and had reset traps in the basement; but, because I had had such a good experience earlier with Fermin and Certech, I called them up to get their professional experience and assessment. As was the earlier case with the Ant issue, they were responsive to my call, came out within 24 hours, and just brought a huge dose of professionalism and reasonableness. I don't know what it is with the pest business; but, I just always feel like I am being fed a bunch of scare tactics, oversold, and then left in the end too often with an ineffective solution , a long-term contract and difficulty in following up once they have the contract. That just hasn't been the case with Certech and it stands out as different from their competitors and is also so refreshing. Fermin was as patient, friendly and knowledgeable as he had been when he came out to our house earlier for the ants, and he worked with me to acknowledge the work already done and then advise and recommend only what incrementally needed to be done. He even helped me clear the catches I had in the traps I had set and rebait them. He also confirmed my assessment on the place they were likely getting in and helped me reclose that; but, also took it upon himself to do a comprehensive search for other exclusion gaps including up on the roof when he noticed a place our oak tree was touching the house. At the end, once again differentiating themselves from their competition, there were no exorbitant charges for the visit and no hard sell for a continuing contract. He was so honest he even told me I should be fine now with how things were and just to keep monitoring the exclusion areas and check the traps now and then. And, to call them again if I ever need them. So refreshing and, once again, renewing my faith that friendly, quality, professional service is still available in our community. read more

Gareth did a great job covering open spaces where rodents could enter the house. He then set traps in places where there was evidence of rodent activity and these were checked periodically for trapped rodents which were still in the house. The pest control was completed after evidence of existing rodents were not found. We found Gareth friendly and an expert at controlling existing rodents and keeping out future rodents. We highly recommend Certech Environmental Services. read more

I have been a client of Certech for six years. They consistently deliver stellar service and at a great price. They are always on time and have great communication before and during every visit. For instance, we keep our backyard gate locked, so they call every quarter to schedule a convenient time for the service rep to come by. Although every rep we have worked with was friendly, professional and respectful of our property, our current rep Jonathan is amazing. He's been our rep for two years. Every time Jonathan visits, he takes great care in removing spider webs and thoroughly spraying the property. He does his job with joy, which is what I feel knowing the insects are under control! Jonathan always asks about my family and is such a genuine person. I never thought I would love a pest control company this much! read more

Certech Environmental Services was great. Justin came over to inspect a potential termite infestation that was flagged by a different contractor. He informed us it was an old infestation and was extremely helpful. Would definitely be in touch in the future if we have any ongoing issues. Thanks again! read more

I had a ground wasp problem and Gareth came out within a short notice window. (Need to let him know so he can bring his bee suit). He and his team were super communicative and fair with pricing from the first interaction to him coming on-site. My neighbors happened to call pest control the day before so the wasp issue was resolved but Gareth still did a proper inspection and even did a rodent inspection proactively. He made helpful recommendations, knows his stuff, was honest, and was friendly. Other pest control services made me feel like I had to purchase expensive services or I would be faced with major issues. If I need anyone for pest control, I will be calling Certech first. Thanks Gareth! read more

Exactly what I was looking for. They were super responsive, had great communication and Jose was very thorough and knowledgeable. Already feeling relieved after the first spider treatment! read more

They were fine. No issues, just didn't get the sense this was actually anymore sophisticated or environmentally friendly than any other approach. Seems like it might be a bit of greenwashing to justify price. read more

Great communication both before and during the actual service - not to mention affordable. Ants started disappearing within 24 hours, wow!

We have been using Certech for 5+ yrs and now at our new restaurant. They have done an amazing job at eliminating the roach issue at the new restaurant. I couldn't imagine a better service provider; from dealing directly with the owner to developing relationships with the technicians that provide the service. All around a great company and amazing custoimer service. Thank you so much read more

Started the service three weeks ago. After the spray inside the house, it killed tons of cockroaches. One week later, follow-up spray in the house, killed more due to hatching. Another week later, they spray outside and killed more with some big one. Now, it's pretty much done. Thank you so much for the pest control service. read more

Still a fabulous company! Called for an area - new neighbor allowed access to a side of our building. Justin came out gave a great price Jonathan was great with the plunge spray & drilling. Love this company! read more

We selected Certech to deal with an infestation of rats under our house. We hade several bids and Justin's was the most professional and well described. Justin and his crew came on time and carefull dug a trench around our house and installed wire mesh and concrete to prevent further entry of the rats. They then placed muliple traps in the crawl space. They will return in 2 weeks to inspect, clean and place new traps as needed. The did a great and job and cleaned up after. read more

Highly suggested! They get things done professionally. Amd on time. I got quotes from multiple vendors and they stand out from professional prospective and pricing. read more

Fermin from Certech Environmental Services came to inspect our home after we had issues with rats, and we couldn't have asked for a better experience. He was incredibly thorough and professional, checking every part of our property and explaining everything he found. Throughout the entire process, Fermin's friendly and helpful attitude made things feel much less stressful. Highly recommend Certech Environmental Services and Fermin if you need pest control help! read more

I contacted Certech because I thought I had bed bugs. Jonathan came out and did a very thorough inspection and found that I was wrong, then offered some suggestions about what else could be biting me and how Certech would solve them. Jonathan was very professional, friendly, and supportive. I couldn't be happier with his service. read more

Our tech, Jose Navarro, is everything you want in a service professional. Knowledgeable, professional, always on time, and gets the job done. Couldn't be happier. read more

Certech's crew did a 100% excellent job of rodent-proofing my aunt's house and cleaning up a previous attic infestation. They poured concrete around the bottom of the shallow foundation wall to stop pests from burrowing under it to enter the crawl space. They filled entrances and crevices to the attic. They cleaned up the droppings in the attic (I verified myself that they did a good job of it). Finally, they set traps in the attic and crawl space - no signs of rodents 1 month later. They even found and repaired an air duct leak while they were in the crawl space by my request. Justin, the general manager, is very professional and easy to work with, and unafraid to do the hard and dirty work himself as well. No pushy sales tactics to try to upsell me on things we didn't need like rat slabs, insulation replacement, etc -- just honest work. The 2 other associates were also very courteous and professional. The pricing was also very competitive for the amount of work done. I 100% will use or recommend Certech going forward. read more

I had a pest inspection performed and signed up for pest control. I am very pleased with their attentiveness and knowledge. Certech has been very helpful and I want to be sure people know that this company has very good work ethic & results. read more

Excellent company. Very professional, knowledgeable, and reputable. I had them do an inspection after Macys department store delivery guys insisted I had bedbugs because they found some yellow larvae on my old mattresses. No blood was found, which is what bedbugs leave behind. Found out it was from carpet beetles. Everyone has them in their homes. You just vacuum them up. read more

Several days elapsed before the automated responses turned into an appointment. Once here, the tech, who had to borrow a ladder from us, visually scanned the attic from the access point. In closure, he said "yes, we could do a whole treatment." I asked what kind of schedule we were looking at, the response was "next week, if you decide to go with us, but I know you have choices." And that was that. A few days later I sent a follow up email asking if they planned to send an estimate and received no response. read more

Excellent customer service! Tech Alex did a great job and called me several times after the inspection to check on me. Highly recommend!

I highly recommend Certech, they are professional, responsive and very respectful. Alex at Certech took care of us and treated us like family. read more

Certech Environmental Services - Pest Control Near Me - Walnut Creek, California

We moved into a new home recently and one night, whilst I was doing some work at around midnight in the basement, I heard a rustling noise. I looked over and let out a silent scream as I noticed a rat run past me. I very quickly went through the various stages of grief, first doubting that i had even seen it, before getting angry that our home already had a rat problem. After feeling sad about it, I accepted it and hit up Yelp to look for a good rodent exclusion provider. We got a few different quotes from different providers who educated us on the different ways to exclude rats. One vendor was extremely terse and turned up 6 hours early for a Sunday afternoon appointment - walked in, told us we had a rat problem, and then walked out. They later texted us with a one line quote... Working with Sean from Certech was almost the entirely opposite experience. He turned up, listened to our concerns, gave us some thoughtful advice and walked us through how he would exclude the various problematic areas in our basement. He suggested using bait boxes around our property to reduce the probability of rats getting in (although I've later read that these can harm owl wildlife since they consumed the poisoned rats - so something to be aware of), and proposed using concrete to permanently seal up any small holes where they might be coming in. He also pointed out several small gaps that we hadn't originally considered as being a problem and mentioned he would apply wire mesh to them. We went ahead and scheduled with Certech (on my birthday, funnily enough) on the basis of their professional approach and competitive pricing. Two weeks later, the traps that have been set are still "empty" and we haven't seen any evidence of rodent activity: no excrement and no paw prints in our subarea! We're happy customers and now I can go back to tinkering in our basement late at night in peace. read more

Justin gets the job done right and makes sure your home is left clean, clear and protected. I didn't want to deal with the dead rats we found left behind from the previous owner. I didn't know if there were any live ones left. Justin came right away and found a point of entry, assessed the ancient rat remnants and gave me a price to just make it go all away. He patched holes, filled in concrete, cleaned up the crawl space by vacuuming up the droppings and filling up 4 trash bags of debris including insulation the rats used as a former nest. Justin is professional and damn good as his job. read more

Have had them out twice, they are prompt and professional, I appreciate their attentiveness to our home's needs. RIP ants.

Absolutely no one wants to deal with pests, but in the unfortunate case that it has, I highly recommend Ada and Fermin ("Ferminator") at Certech! Ada is on top of her game replying to emails and coordinating with their techs who are on site. I learned more than I want about pests and treatments from them but feel like a much more empowered consumer in this area thanks to both of them. Really, really glad to have found Certech and that they were able to take care of the situation! read more

After researching, gathering multiple quotes, and dealing with numerous companies, I could not recommend Certech enough! Justin came in and dealt with all of the issues we needed eradicated with complete professionalism, efficiency, and speed. Certech has the most reasonable and fair prices than all of the other pest control companies nearby. The customer service is amazing bar none. Justin was always prompt with his responses, open with communication, and you could tell was not just trying to make a profit but actually help you with what you need. 10/10 will always be using Certech in the future for any of my pest control needs. read more

I scheduled Certech to deal with a serious ant problem (much bigger than your typical ant situation after heavy rains or extreme heat). Their Technician Gareth was communicative, professional, and punctual. Like I said, this was a bigger problem than normal, and Certech stood by their guarantee. Gareth came back a couple times to get rid of the ants, trying something a little stronger each time, and solved the problem. Thank you, guys, I won't hesitate to call you again. read more

Gareth has been great to work with. We had him come out for two different instances, the first was to secure the outside of the house and look for any exposed holes. A year and a half later after some construction we noticed some rats in our garage, Gareth was able to help sort that out for us as well. Overall my experience has been great, Gareth is always professional, calm, and on time. Will be happy to continue using their services. read more

I'm super scared of spiders, so after years of owning a house and trying to deal with them myself, I finally gave up and called a pest control company. Best choice ever! Sean came and looked at everything, filled in a bunch of cracks, removed two wasp nests, sprayed the house against spiders inside and outside, removed all the cobwebs (even from my super-cobwebby retaining walls and covered deck!), and laid down sticky traps to see what else we catch in the next couple of weeks. He even patched up the house where the wasp nest used to be! And he was super knowledgeable about pests and let me know which of the dead spiders could bite but had no venom, and which were completely harmless. Now, I and my 3yo can finally use the house without fear, and I can start all those home improvement projects I've been wanting to do since the shelter in place started :D Thanks Sean and Certech! read more

I highly recommend Certech. I had an infestation in the roof AND the basement. Justin initially came and assessed the situation. Justin was onetime, approachable and professional. It took one month of appointments to abate the situation. During this month of appointments I worked with Garreth. Gareth was also professional and punctual. His communication was on point as well particularly when he was stalled due to traffic and/or a previous job. Thank you again Justin and Gareth. read more

Justin was great! Timely, helpful, and got the job done quickly. Highly recommend this business.

Called multiple times, got a schedule and cancelled the next morning. The boss his name is Justin called back but I missed his call. Then, I called back multiple times and left a voice mail. Next morning, I called customer service to ask for another appointment and the lady said she gonna talk to the boss Justin and get back to me but still no one ever get back to me. It has been 3 days for me. Just to be fair one star for your customer service. Maybe the company doing so good that u guys can ignore any customer already. read more

Super knowledgeable and responsive. Signed up for regular pest services after a quick and easy consult and survey of my yard. Everyone I've met at Certech is great and so nice. Big thanks to Justin and Sean for making the process easy and taking extra care of our yard and home! read more

Certech Environmental Services took care of our termite problems and Justin readily came back to look at my concerns even though two years had passed. read more

While we ended up taking care of the problem ourselves, Justin was super helpful and responsive. We may be calling him in the future if our remedy does not hold. Justin was the fastest response and took time to call us himself. read more

I am thankful to this company and Justin was able to attending to my rental property's ant issue on the 911 call for help. I have contacted 2 other companies and they told me they don't have enough workers and they won't be able to help until next week. Justin would drop everything to come out and he was little late but he really trying hard to make it there to finish the job. My tenants is very thankful that Justin fixed his ants problem the next morning after my call to his company. He was there more than one hour doing a good job! I don't mind delay getting the invoice sorry I was stressed about wanting to get my invoice sooner. read more

Great company! Sean came out and did a very thorough "crawl thru" of my house. He found entry rodent/vermin entry points others could not. We discussed several possible solutions. Very knowledgable guy with plenty of experience. Highly recommended. read more

Just came in and quickly and efficiently did the job I wanted done. No upselling. Great communication.
