This is the only honest company I've worked with in years. After another company told me I needed to pay thousands of dollars to remove and replace "heavily infested" insulation in my whole attic, I got a second opinion from Diamond Rodent Proofing and Andrew did a thorough inspection and told me the truth, that there was no sign of a rodent problem and that I was being scammed. He just saved me thousands in an unnecessary attic overhaul, thank you, Andrew! Highly, highly recommend this company, just for his honesty alone. read more

Andrew did a fabulous job for me excluding rats and mice from my attic and garage. Other companies I tried over the years caught some rodents but failed to truly exclude them. Andrew's crew inspected from the exterior tile roof as well as the interior spaces, found and sealed entry points. And Diamond guarantees their work. read more

I highly recommend Diamond. They completely solved our mouse problem on their first visit after having mice get into our house somehow for 3 months. Keep in mind the price includes free visits for 2 years of check ins, which is critical to ensure long term rodent proofing. read more

Great service. Highly experienced team Prompt, professional and friendly. Thanks Andrew....no more rats in my garage! read more

It was smelling like Jeffrey Dahmer's house downstairs, and we were pretty sure something large died underneath the house. The team at Diamond Rodent Proofing showed up the same day, removed the stinky dead rodent from under the house, and offered us a fair price to patch up the holes underneath and around the house to ensure it was rodent-proofed. They backed all their work with a guarantee, and thus far no more stinky rodents. Definitely worth calling them out to your house to do an estimate. read more

Good at their job IF they respond. So many communication issues and excuses. End up paying quite a bit of money for little to no service. Would not recommend. read more

***** Warning: Stay away from Diamond Rodent Proofing ***** I've rarely felt compelled to write a negative review about a business. But sadly, the level of unprofessionalism and lack of ethics we've experienced with Diamond Rodent Proofing warrants a public warning to anyone looking to hire them for rat or rodent issues. If you're looking for reliable and trustworthy rodent remediation services: Stay away from Diamond Rodent Proofing! See below for recommendations on who to hire instead. In summary: I recommend NEVER using Diamond Rodent Proofing for any pest control needs. They are unprofessional, unreliable, and unethical. Andrew and his team disappeared after taking our money and delivering 0 results. How unprofessional & unethical was Diamond Rodent Proofing? After agreeing to a fee of $2,800 to fully rodent-proof our house and eradicate the rat issue that was plaguing us, Diamond Rodent Proofing not only failed to deliver any results in terms of rodent eradication (= did not catch a single rat) but to add insult to injury, Andrew stopped responding to any communications and became unreachable. Andrew and Ashley decided to completely ghost my repeated attempts to communicate with them via email, phone and text messages asking him for a partial refund given the total absence of results on his part. How did we get here: Like many Oakland Hills residents, we've had to address rat issues sporadically. The process is usually the same: rodent-proof the perimeter of the house/crawlspace, and set traps to catch any rats stuck inside until they're all gone. Rodent remediation companies will typically offer a 2-3 year contract period during which they will come back, reset traps, and check for new entry points. When we started hearing rat activity in the house, we set out to get quotes from various contractors: 1. Honest Rodent Proofing: $13,700 quote. they suggested pouring a concrete slab in our crawlspace, arguing that we would always have rat issues without a concrete slab. 2. ASAP Rodent Proofing: $2,800. Rodent proofing + 3 months of guarantee 3. Diamond Rodent Proofing: $3,000 (2,800 if paid cash). Rodent proofing + 3 years of guarantee 4. Rat Patrol: $700. Rodent proofing + 2 years of guarantee We decided to hire Diamond Rodent proofing because (1) Andrew was very thorough and professional in his initial inspection (2) he was available to start immediately. We were expecting a baby in just a few months and absolutely needed the house to be clean and rat-free by then. After their initial visit and spending half a day rodent-proofing the perimeter of the house, we continued to hear rat noises. Over 4 weeks, Andrew returned to the house 3 times to further inspect the perimeter - never finding the entry point. Meanwhile, the situation was worsening, and the rats were starting to cause extensive damage to our HVAC system, chewing their way through our heating ducts. We eventually had to resort to hiring another contractor who was finally able to find the entry point that rats were using, seal it and eradicate the rats that had by then completely nested in our subfloor and HVAC system - contaminating half or our heating ducts with urine & rodent droppings to the point that we could smell them in the house. Given the complete lack of results from Diamond Rodent proofing, the fact that we ended up having to hire another company to solve the problem and the massive additional expenses we incurred having to replace our HVAC system - we requested a refund from Andrew & Diamond Rodent Proofing. That's where things became unprofessional and unethical - and why I'm writing this review today. read more

I have to give these guys one star. I can't judge the quality of their work as they didn't show for either of the estimate appts that they made. read more

I'd give zero stars if I could. A year ago I got three quotes for a rat problem in my attic. Andrew was highest by $1000, but he offered a three year warranty where the others only offered six months. I thought the extended warrant worth the additional money. Big mistake. Since performing the initial work and one inspection a few weeks later, I have made four appointments to have a re-inspection done, and have been stiffed all four times. Bottom line-the warranty I paid an extra $1000 for is worthless, as this company takes the money and runs! My advice, if you're thinking of doing business with this grifter--DON'T! read more

Ashley and Andrew communicated very well and were prompt on their response. Work done by Andrew was great. He cleaned out some rodent droppings and debris from under a barbecue and sanitized it. Everything came out wonderful. Highly recommended.! read more

A very pleasant experience with Diamond Rodent Proofing. Initially, I set up the free inspection with Ashley. She was very professional and courteous. After promptly setting up the free inspection, Andrew arrived at my door on time with a great attitude and excellent work ethic. His knowledge in the industry was very evident with 20+ years experience in the industry. After performing a thorough inspection pinpointing every possible entry point he then explained in great detail how the whole process would work. shortly after the inspection, Andrew wrote up a very detailed, competitive estimate on what the job would entail. I highly recommend you reach out to diamond rodent proofing. You will not be disappointed. read more

New home to us and sitting outside we saw a big,fast critter climbing straight up the stucco wall! Called these people and they rat proofed our entire home. Rodent problems gone and very pleased with their service and follow ups. Call them and you'll be glad you did! read more

The work was great and their follow up has been awesome. We are very happy and glad that we found them! You won't be disappointed. They respond very quickly if you need anything. read more

I am so very impressed with not only the service, but the guarantee of Diamond Rodent Proofing. They were quick and responsive 6 months ago when they first came out to our home and did our initial 'rat trapping and extraction' and then again, 6 months later, totally backed up their guarantee and came back as the rats found a different way to get into our lower crawl space now. We would strongly recommend Diamond, especially Andrew. Hands down great. When you want it done properly and want business that backs it up. read more

These guys came back and finished the job and they did a great job in the end. The mice have not entered any structures in the areas they sealed up. They came back to reset traps and after their second visit to set traps I have not had any mice issues. It's unfortunate that I had such a bad experience the first around and it took so long to addresses because they do a good job. read more

Wow! The first call to the office line Ashley had me scheduled next day. The inspector Andrew also owner/operator came out to show me and my wife his way to seal our house from start to finish. 2 days later the work was performed with a discount for being in the military. 1 year later our house is still permanently sealed. I couldn't believe how much we saved from switching out our pest control guy to getting the property rodent proofed. Worth every penny. The amount we saved over not paying a monthly service but also getting permanent results. Thank you again Diamond we highly recommend your services. read more

Diamond Rodent Proofing - A tricky hole found that allowed rodents into our house. - Pest Control Near Me

We have been using Diamond Rodent Proofing since 2021 and they are excellent! They are extremely responsive, very professional and know what they are doing. The owner, Andrew, was the one who came to do our initial estimate and was at our house with his crew repeatedly until the issue was resolved. Few years later, we are still covered with the extended guarantee and they come frequently to check not only the inside but they check all around the house and they plug any potential entry points. If we observe any issues, one call to Ashley and they come right away and take care of it. Andrew and Ashley, thanks for a great service! read more

I waited a couple of months to write this review. I wanted to make sure we were 100% rat free!! Andrew and his team are amazing at what they do, getting rid of RATS. Everything from the initial phone conversation and setting up an inspection went smoothly. They even called the day before to confirm my appointment. The inspector was great! He was able to answer all of our questions so we signed with him right in the spot. We were able to make an appointment to have the work done a week later. The whole set up was extremely clean which we appreciated! The whole job was done in a day. They came back a few times to check traps to make sure the rats were gone and gave us a great guarantee. Happy to say we are finally rat Free Thank you Andrew. read more

Diamond has done a great job in getting rid of rats in our house....not only our house, but also with several of our neighbors. They are very responsive and professional. I can't recommend them highly enough. read more

I called Diamond Rodent Proofing and coincidentally, after talking to our neighbors, they had used them and highly recommended them. We purchased a new home and we were having major skunk issues since we were from the East Coast we had no idea that there is a large rat population by our house and skunks hate rats! Andrew did everything he said he would do. Everything is sealed up all, the exterior entryways for the rats and skunks. Since he did that we have not had any more skunk odor and now we're just dealing with next steps which will be to remove the dirty insulation as soon as he is sure there are no more rats living in the crawlspace. We are hoping the clean up with fix the odor that is in our lower level. read more

Stop looking and just call Andrew. We had skunks and rats at multiple locations. I wouldn't trust anyone else.

The team at Diamond Rodent Proofing is very knowledgeable and reliable. I've had excellent experience with this company since the first time I called them on 01/2022. I had a rodent problem in my house Andrew came out and inspected the whole house carefully. His crew showed up the next day to seal all points of rodent entry (located in different parts of my house including behind the bushes, next to garage doors, roof, etc) They set tramps and checked on them once per week for a few weeks. Shortly after a month our house was free of rats. One year later I called them because I heard noises in my garage again. Andrew came immediately, he inspected the house and found one new potential point of entry and they sealed it, set new tramps and checked them several times. Once again my house is free of rats. I know I don't have to worry the next time that I hear a sound, hopefully never, because Diamond Rodent Proofing is the best at what they do. I highly recommend them! read more

These guys are unbelievable! Amazing!! If you have problems with rodents, CALL THESE GUYS!!!! Brian just came out and scanned every nook and cranny of possible access/entry into our home and sealed it. Brian crawled, hopped up on the roof, explained stuff to us and was good natured the whole visit as well. Andrew was also a big help and told us they would come out in 3 days and check again to secure the work making sure no animals revisited our house. The secretary, Ashley, was also a team contributor to the success of our appointment. LOOK NO FURTHER FOR RODENT PROOFING!!!!! We are customers for life! Emily and Filippo Danville read more

I absolutely love the honest transparency that Diamond Rodent Proofing provides. Andrew came out tonight to give us a free estimate on some nice we have been hearing in the attic. Andrew took a look at our home and informed us that our home already had been proofed by the looks of it (we recently bought our home). He let us know it may be a hole somewhere in the roof but something so minimal that we could probably do our selves but if we needed him he could always come back. Andrew made me feel so safe knowing I wasn't going to be robbed of some money I could use on my kids.. I know that when I have a problem I can safely call him back to take care of our home. I will be for sure calling him back need be! read more

Diamond Rodent Proofing exceed our expectations. Andrew was prompt, professional and efficient. We hired him on the spot after he inspected our home gave us a quote, and explained the process to rodent proof our home and their guarantee. Technicians were always on time for appointments and worked with a minimum of inconvenience to us. Ashley was very accommodating, matching appointments to our busy schedule. Our rodent problem was solved almost immediately. read more

After having issues Andrew came out personally to handle inspection. I'm definitely giving them another chance.

I spent thousands of dollars for these guys to solve my rodent problem at my home, but it was never solved. They supposedly sealed every 1/4 inch opening in my house to prevent mice/rats from entering, but the issue remained even through their "warranty" period. They would just come by to check on traps they left in the attic and would catch mice then say it's OK now and then I'd have to reach out to them again and again after I saw mice again and again. I don't think there was ever a period of time where I truly didn't have rodents in my house. I wish I never hired this company, they charged me so much money, but I didn't see the results that they promised. read more

Horrible contractor service bad. Reliability bad. Damage to air duct bad . Had to get another contractor to finish the job. They did pay me back the price of the insulation. They fix the electrical damage they did but not the air duct damage. Stay away Fly by night Contractor. read more

This is an update for my recent review for this business. Shortly after posting the aforementioned review of Diamond Rodent Proofing, I was contacted by Ashley who apologized and said the lack of response to our household's calls were due to issues with their telephone service. Although I had already reached out to a different company for service, I decided to give Diamond Rodent Proofing a chance to remain our service provider based on apologies received, explanations given, and being assured by Ashley our service guarantee would be honored. An appointment for 09/13/2022 was scheduled. The tech who responded that day directly facilitated a rescheduling of service with Ashley to 09/16/2022. Without wanting to go into heavy detail, I will say the attempt to retain our household's business had failed due to no one showing up for the rescheduled appointment. read more

We worked with Andrew and his crew last year after moving into our home and they were very diligent about setting traps and making sure all openings were closed for any return visitors. They were responsive and responsible and guarantee their work so if you have any issues, I'd get on their schedule! They weren't about just getting the job done but getting the job done right so I feel like the money was well spent. read more

I can't say enough how amazing Andrew, Ashley, and the rest of the team have been! We were at our wits end and in 2020 hired them to help us with the rodent issue in our attic. The initial set up was very detailed and Andrew personally came to check and give guidance. Since then they have provided continued support and returned to check anytime we felt that an issue arose. Thank you for helping us- the rodent issue is intense right now in our area and we are so grateful. Don't think twice, this company is honest, reliable and recommended! Thank you Andrew and team! read more

I woke in the morning to a deceased cat and rabbit on our lawn. I wasn't sure what to do and called Diamond Rodent Proofing. I explained the situation to the lady on the phone and she offered to discard them for me. I gave her my address and she was here in 20 minutes. I really appreciate the way Diamond Rodent Proofing helped to solve my situation. read more

We had a terrible rodent problem in our garage which is now under control thanks to Diamond. These guys put in the time and came up with some thoughtful solutions to contain the issue. I really regret that they no longer service SF, but I understand it's a long way away. Maybe they'll figure out a way to get some local employees here to expand their reach between now & then, but I'm going to be so bummed when our service agreement runs out. read more

Diamond is an awesome company, I called them for rodent proofing my townhome, he gave me a quote and advised me to rodent proof the entire building, while giving the estimate he also fixed a vent. Would recommend. read more

Andrew and his team did a very thorough job identifying and closing likely access points. They provide regular follow up visits to ensure job is complete and include a multi year warranty. I have a unique shaped house and property borders open space so rodents are persistent and other pest companies were hesitant to offer a free warranty. Diamond was up for the challenge and did a fantastic job. Highly recommend. read more

DID NOT USE SERVICES.... .... but, I requested a quote for a very specific property and Andrew responded within minutes with a professional response trying to make it work. Thank you! read more

Initial inspection appointment was a few days ago. They called us after the appointment time to cancel and reschedule. The second appointment was Sunday 11 to 12 time frame. No Show, no call. I tried to reach them by calling, messaging, no luck. I wasted my Sunday waiting for them. read more

Best company in the bay area if you have any type of rodent problems. Everyone is super professional and will meet all expectations. They know their stuff, the owner has been in the industry a long time so they definitely have the needed experience to do the job right. Highly recommend!!! read more

We have a rodent problem in our house. A Contra Costa Vector Control representative verified our worst concerns after an inspection. We hired Diamond Rodent Proofing to fix our rodent problem. The owner, Andrew, inspected foundation vents and other entry points for rodents. He left us with a detailed proposal with estimated costs. The day that Andrew and his crew showed up made us realize that they would perform specific tasks and more in their work day. For example Andrew plugged two entry points in our kitchen and did not charge extra. One of the crew vacuumed part of the crawl space and brought out bags of insulation composed of rat urine. The crew also sealed several rodent entry ways on our roof. They sat traps and conducted three follow-up visits so far. We strongly recommend Diamond Rodent Proofing. read more

Diamond Rodent Proofing is the real deal! They really want to solve your problem and are committed to staying with it until they do. After years of using another company that only seemed interested in collecting a monthly maintenance fee from us, we got frustrated and turned to Andrew at Diamond. He assured us that our home could indeed be rodent proofed and they were able to find and seal a rodent entrance hole that no one else at the previous company had found. Everyone at the company has been a pleasure to work with. They have assembled a great team of hard workers who are extremely courteous, including Ashley who is always available to answer any questions and arrange appointments around my availability. Absolutely the best experience using this professional company and I highly recommend them. Thank you Diamond Rodent Proofing! read more
