Andrew and his team are definitely the experts. He, David, their crew and Ashley at the office did an excellent job for us. We had very persistent rats in our crawl space that were damaging our heating vents and spreading mites. Initially we made the mistake of hiring Clark Pest Control. Clark only offered a 6 month guarantee. We went through all 6 months of costly and unfortunately ineffective work by Clark who tried many different methods of rodent control. In the end we hired Andrew McKinsie and his team from Diamond Rodent. They were the ones who finally managed to stop the return of the rats. They were knowledgeable, professional and confident of their methods. They were able to tell us why other methods have not worked in our case. They were confident enough to give us a lengthy guarantee. I would highly recommend them. When we first started looking for a vendor, we interviewed 3 and settled on a large corporate outfit called Clark that was recommended to us. But Clark turned out to be the wrong choice. They were more adept at doing pest control for commercial installations and residences. But they were not very knowledgeable with rodent control. In addition to the rodent work which included putting large amounts of concrete around suspected entry areas, crawl space and setting up wildlife cameras, they also had us sign on to an ongoing contract for pest control. None of what they did was effective at stopping the rodents from returning. After 6 months without success, we hired Andrew and his crew who were able to eliminate the rodents for good. We have since recommended them many times on NextDoor. read more

I had high hopes and trust in the beginning for the small business, unfortunately my blind trust was misplaced for Andrew. Just before the day of appointment then I was contacted to pay a bill in full amount. Then I was shocked to see he didn't do any cleanup at all, and communicated misleading and subjective information without heeding the basic facts and established rules and practices. Very unprofessional with exceedingly poor judgement! read more

It's easy to see why they have all 5-star reviews. I have worked with a few other companies over the years, and all in all, have been fairly happy with them, but now that I've tried Diamond Rodent Proofing, I won't be going anywhere else. The customer service you receive is beyond outstanding from the initial phone call to the inspection to the technicians coming out to take care of things. Plus they come out every few months to check to see if there any other issues -- I've never had another company do that. If I could give them 10 stars, I would....they're that good! You won't be disappointed going with Diamond Rodent Proofing. read more

Andrew and his team have given me some much-needed peace of mind. After trying to deal with the rats on my own & checking out other companies, I was completely frustrated & at a standstill. I found Diamond Rodent Proofing & after meeting with Andrew, who is very experienced & super-knowledgeable about rats, I was confident he would take care of the problem. After checking out the property with me, they went to work in the crawlspace, attic, on the roof, inside, outside--everywhere! They were extremely efficient & found many access points I would never have noticed myself. After they had sealed everything & removed the damaged attic insulation, they set their traps in the attic, crawlspace & garage. That was last year & they have since returned every three months to check the traps & review their work. No rats! Peace of mind! Great people! Diamond Rodent Proofing! read more

I highly recommend Diamond rodent proofing! The service and customer service is outstanding . Ashley is amazing with booking/ setting up appointments and returning calls. Andrew was amazing when we had our first consult and Chris was flawless with the work they did on and in our house. He was very thorough of what he was doing. Everyone was so helpful with any questions/ concerns I had. They gave me so much information and tips I never would have known to do. I gained so much knowledge from diamond rodent proofing. Everyone was so so nice and helpful. Anyone with rodent issues, I give them a 10 star and would recommend to anyone of my friends and family. Thank you guys sooo much! I greatly appreciate your service! read more

Andrew came out to give me a quote, and answer my questions. He is very knowledgeable about this business. Ashley, is such a blessing too. She scheduled the work to be done ASAP. The crew that came out to do the work were super professional and explained everything to me. I am extremely happy with theses guys. I totally recommend them. read more

Diamond Rodent Proofing is committed to thorough, high quality work. Three weeks ago they did exclusion work to seal rats out of a cottage and attached garage. The quality of their work was so good that they immediately trapped the rats (within 3 days) and there has been no problem since. When they come out to check traps, they do a complete inspection of the whole building to check for any evidence of new activity. I have used other companies over the last 10 years and have never received the level of service Diamond offers. I feel confident that if there is a new problem, they will be on it quickly and thoroughly. I highly recommend them. Thank you, Andrew, David, Dennis, Chris and Ashley read more

I would like to thank everyone at Diamond for doing an outstanding job of ridding my garage and attic of rats. All of the people who come out for inspections have been professional and done a thorough job of checking traps and bait on a regular basis. A special thanks to the office for timely response to scheduling regular check ups. read more

I can't say enough awesome things about Andrew, Ashley and their team! After seeing some mice around our place, I had a terrible time even getting anyone to call me back. But Ashley called me right back & scheduled a very prompt inspection. Andrew showed up on time,was friendly and informative, inspected our place and clearly knew just how to handle our problem. His team expertly sealed up entry points to our house, laid traps, and came back regularly to inspect until they were sure the visitors were gone. The fees they charged are more than fair for all the work these guys did, not to mention giving me peace of mind! They really take pride in their work and care about their clients, and it shows. If you have a rodent issue, don't even bother calling anyone else. Call Diamond first. Highly enthusiastically recommended! Thank you Andrew, Ashley, Doug, Dennis and team!! read more

It seems this year is a time of heavy rodent activity here in Moraga. We found our home being overrun with brown rats and Norwegian rats. Based on his experience, a Lafayette friend suggested we call Diamond Rodent Proofing. We were very happy with the service they provided. The owner, Andrew came out promptly and gave us a free estimate. The price was reasonable and we scheduled the service which involves an initial visit to block all access points to the house and the laying of several traps followed by visits every few days to clear the traps and set new ones. Once the traps stay clear Diamond Rodent Proofing provides a one year guarantee. If we see any more rats they will come and deal with the situation for free. The office is very responsive and the personnel who visit the house are timely, clean and courteous. read more

Andrew was incredibly knowledgable and knows his business. I have had other companies come set traps and have been unsuccessful, Diamond came and completed the clean up, set traps and followed up as promised. I highly recommend them for rodent proofing your home. read more

Andrew is an amazing young man and business owner. He is also an expert at rodent control, and did a thorough and expert job at our house. Andrew returned my phone call within a couple of hours, showed up for the inspection on time, laid out a plan of action, and executed the plan as promised, on time, with great professionalism and a positive and friendly attitude. And he returned, exactly as promised, to check the traps, and then again to verify that our basement was rodent-free. Diamond Rodent Proofing is the gold-standard for anyone with rodent problems. Call Andrew today. Don't waste time and money with anyone else. read more

This guy is excellent I had a bad problem with rats in my rental omg I had a different company come out I believe Rat Trappers I thought it was handled And then the party in the walls the rats took over the house I called Diamond Rodent Proofing Andrew came out I explained I had already dealt with the first company and thought the house was sealed Hugh mistake Andrew from Diamond Rodent Proofing led me all over the property and explained what the first guy did was creating more opportunities for the rats to create more tunnels in the house instead of sealing the house I was in shock he showed me where and how what the first guy did made the problem worse Diamond rodent proofing came out Monday sealed the whole house told me to put my food away in jars are the fridge where they couldn't get it and literally starved so many rats that that other guy by not sealing the house allowed access for the rats to go in and out and bring their families and have parties in the walls real eye opener for me thank you Andrew at Diamond Rodent Proofing fantastic job read more

Diamond rodent proofing is the most reliable and effective solution we have tried for proofing our home in Berkeley. Andrew and his team helped us figure out a mother raccoon and her babies had decided to take cover inside our walls. They were making a noisy racket in the evenings and each time we thought we got them out (that is, we actually saw them run out), they would make their way back in. Andrew was tireless in coming back and making sure the problem was solved, plus he gave me a very fair rate when he assessed the situation initially. He confirmed he would not need to charge for sealing the entire house--the first two estimates we had were 4 times what he charged because they insisted they would have to do more work than just what was necessary. I can't recommend them enough, they are worth every penny and then some. read more

These guys are as good as it gets! I am a property manager throughout the bay area and i have dealt with other rodent companies and to say the least, these guys are the best thus far. They worked on my primary residence which has had issues for as long as i can remember. Other companies have come here and their work did not hold up at all....The attention to detail is what stood out to most with Diamond Rodent Proofing. Andrew the owner gave me a thorough inspection and Chris sealed up every potential entry point. They both even took the time to educate me....We have not had any activity since they did their work. They were honest, and in my opinion worth every penny. I will for sure use them again in the other properties i manage.... read more

Diamond Rodent Proofing is the best! We had a nasty and persistent problem with rats in our attic and they have solved the problem! It was not easy, and they were out several times. During each visit they throughly explained what they were doing and how they intended to solve the problem. Their team was determined to seal every possible hole and point of entry. Paul from Diamond Rodent was especially conscientious and patient and wanted to be sure that were were 100% satisfied. I highly recommend Diamond! They may not be the cheapest, but I am convinced that they are the best! read more

Wow! I cannot say enough good things about this company and the fellows who work for it. We live in a rural area and are surrounded by wildlife. These guys REALLY rodent proofed our two houses. They were back here to check the progress right on schedule. Answered questions, never hesitated to come out (we're off the beaten path, so to speak). Worth every penny and we highly recommend them. read more

I normally take care of any pest around the house, but knew I had to call in the pros when the mice stole food from my traps and I heard them running around the sub-floors. Three interviews later, we decided on Diamond Rodent Proofing based on our online search and references: great choice actually, and great experience. Ashley responded quickly, Andrew came and drew up a plan, went over each detail and presto, we have a contract at a very competitive cost. Their team worked very effectively and efficiently: within three weeks, all points of entry were sealed, traps set, critters caught, sub-floors cleaned. Everybody was cheery, on time, and diligent. I guess they take after Ashley and Andrew! So thanks to Ashley (and soon Annaliese), Andrew, Chris, David and Doug for your excellent, customer oriented service! Recommended without reservations. read more

Great service by Dennis and Eric on the day of the job. They executed as the owner Andrew had described the day of the quote. They were on time, efficient, and courteous. Most of all they seem to have identified a lot of potential openings that other companies missed during their inspections. So hopefully we'll have the rodents out soon. read more

Andrew got rid of the mice that were coming in to dine in our kitchen and pantry very quickly. If you have a rodent problem call Diamond Rodent Proofing. They give you a warranty so you are completely covered. read more

Very fast and friendly service! They showed us where the mice were sneaking in that no other exterminator thought to look. Highly recommend!

Deserves 5 ++ stars. Exceptional customer service. Ashley responded to my request promptly and had David come my house the next day. David is very kind, patient and professional. Andrew has a great team who takes pride in their work with a rat proof guarantee. I would recommend them for any of your rodent problems. read more

While having electrical work done at our house, the electrician saw evidence of rodent activity in the attic. After checking local ratings online, I called Diamond Rodent Proofing and several others. Most didn't respond or had long lead times, but Andrew came to our house the next business day. He did a very thorough inspection and confirmed activity, came up with a plan to get rid of the problem and prevent any future incursions. He gave us a thorough explanation in writing and in person of the plan to seal any entrances to the attic, secure entry points along the foundation (which required mixing and carefully applying over a hundred bags of cement!), along with cleaning and deodorizing. A large crew worked efficiently and expertly, doing a thorough and professional job, leaving the house and work area spotless inside and out. Multiple scheduled follow-up inspections to absolutely confirm success were carried out. The three-year full guarantee gives us great peace of mind. Everyone in the company has been great and you can tell they are all committed to customer service. Nick, who takes care of scheduled inspections, is always prompt and always answers any questions we might have. Ashley is also prompt at returning calls and getting you on the schedule. Diamond is definitely the right company to call if you have rodents in your home!! read more

Andrew personally answered my early morning phone call and assured me that I would get on his schedule promptly. Ashley scheduled our consultation for the very next day. She is very organized and always friendly over the phone. Dennis and Chris did a great job of checking, cleaning and rodent proofing the entire house/roof. Diamond Rodent Proofing is a very professional and timely company. I would highly recommend them. read more

Great service! I was able talk with Ashley yesterday-on a Sunday! Andrew came out right away today and provided me with immediate information. He is very knowledgeable and helpful. read more

After have a bad experience with a different company I was very stressed about the rode t situation in my attic. When I contacted Diamond Rodent Proofing Andrew and his team were very helpful. They are very responsive and I am soooo happy i contacted them. They are very professional and I highly recommend their services. They are professional, friendly and very experienced. read more

This group of guys, Andrew and his crew, get at the minimum a 5 star review. They have done everything as promised and then some. Actually helped with a couple of issues that were not even in the original contract and did so cheerfully and to 100 % resolved. Had used national company and these guys put them to shame. I usually do not recommend but I have no hesitation about Diamond Rodent Proofing. read more

This is a call no one wants to make, but if you have to this is the place to call. Andrew was able to come out quickly to confirm we did have an issue. He then returned two days later to seal up all the areas where the rats could possibly enter through. Andrew was a great guy to work with, he was even willing to play along when our two daughters thought we had "birds" in the attic. read more

We recently began hearing scratching sounds under our dish washer and refrigerator. We called Diamond Rodent Proofing and they were able to trap the little perpetrators and very effectively located and resolved all their various points of entry around our house. We were very impressed with both their timely response and their professional and effective service. Their crews were prompt, educational and personable. We will not hesitate to contact Diamond Rodent Proofing if we need their type of service in the future and will certainly recommend them to family and friends. read more

I called 5 places for rodent proofing and Andrew returned my call within 24hrs. He was professional on the phone and scheduled my inspection within 3 days. He walked me around perimeter of the house and showed points of entry for mice and rats. We have been dealing with mice for months, and I just wanted them gone! He was thorough, courteous and professional. He explained step by step his plan on how to rid us of our rodent problem. His prices were on point, after speaking to several friends who also rodent proofed their home. He guarantees his work and I am confident that we will finally be rid of our rodent problem. read more

Had a rodent issue that I thought was solved, but 5+ years later the issue returned. I decided to go with Diamond based on all the positive reviews. Andrew came out when he said he would and provided a detailed estimate. Diamond did what they said they would do with respect to their estimate. Their employees are professional and accommodating and they are good about following up once the structure has been proofed. Result, problem solved. I would highly recommend Diamond to banish any unwanted visitors. read more

First of all I will like to Thank Andrew for the amazing job and peace of mind he gave my husband and I. We recently bought a house a dream that turned into a nightmare, we found out, when we were in the process of moving your stuff into the house we were infested with mice and rats drooping everywhere. We had to get a storage and move our items into it because there was no way we could bring them into the house. We had contacted 3 rodent companies prior to Andrew they were all family business since we like to support family business, based in Antioch. They had all told us that we were infested but the only thing is that they were expensive and my concern was that they send other people to do the job that they assessed and evaluated. I looked on Yelp again and found Andrews company Diamond Rodent Proofing and I called him and he was really attentive and came out to evaluate our situation my husband got a good vibe from him and he told us not to worry everything will be okay. The good thing about this company is that Andrew comes and evaluates our problem and he also comes and do the work which he proofed our house, sanitize and vacuumed everything and like other companies that are rushing to get out the house he took his time and he even came back the next day to complete the job and explained everything to us and he took the time to talk to me on the phone to tell me that everything is okay and was patient with me and answer all my question and husband. Andrew I will like to Thank you for everything you did and for being patient with us and giving my husband and I peace of mind and finally happiness about purchasing our first house and knowing that we could move in already and not live out of luggages anymore. If you guys want a good rodent company and a good honest person Andrew is the way to go I promise. read more

I would give more stars if I could. I called Andrew because I thought we had a dead rat under our house. I called at least 8 companies and he is the only one that answered! When they came out and looked under the house there wasn't a dead rat.It was a broken water pipe. They were so nice to to take video and pictures so I could show the company who had just been out a few weeks before to unclog my sink. The plumbing company had broke the pipe while snaking it.I was so impressed with Andrew's employees that we hired them to rodent proof our house. What a detailed job they did.Oh and I forgot to mention how careful they were to not make a mess in my house while working! This is a outstanding company. read more

Andrew and his crew were incredibly professional and courteous. I was impressed with their integrity and punctuality. They did not start the 1 year warranty until our rodent problem was fixed. If you have a problem with rodents, Diamond Rodent Proofing is the only company you need to call, you will not be sorry. read more

Diamond Rodent Proofing came through and took care of the mice in my home. They sealed up the possible entry points, strategically set traps, and continued to check the traps until there is no activity. They are courteous of your time and home, and guarantee their work. Thanks! read more

We had rats invade our garage for dog food. They chewed through a rodent proof hard plastic container and had a party! They were making themselves at home in our crawl space. Yikes! We called three places and were so impressed with Diamond Rodent Proofing. Andrew came out and suggested a plan. They would seal off the house and then go under the house to vacuum and sanitize the space and then set traps. They did that and while they were down there, dressed in their alien-like suits, they discovered two tunnels that had been dug from the front to gain entry to the crawl space. They cemented the tunnels and also other entry points. They set traps and came back two times before planting free food to see if there were any rats still present. After ten days the food remained untouched. No more rats! We have a years guarantee. Diamond Rodent Proofing guys were totally professional and priced reasonably. They were on time. The one time they were a little bit late, they called to let me know ahead that they were on their way. Very nice guys, reliable, and efficient. I highly recommend them! Kit King Danvile read more

My wife and I live in Danville, CA and own a townhouse in a HOA. Our townhome is attached to two others, one on each side. Our foundations are elevated, and the three share the same "under the house space". So if one of us has a rodent problem, the other two do as well, as the rodents have access to each of our homes through the "crawl space". We have had some rodent problems in the past, but not major. Recently one of the attached townhomes had serious rodent problems, including skunk and rats and as a result, all three of us. Our neighbor contacted Diamond Rodent Proofing for a proposal. I meet Andrew the owner, and after speaking with him, and having him outline how he approaches the "proofing" we contracted with him, as did my two neighbors. His crew was professional and very "sensitive" to our respective living spaces. They covered the floors with plastic and removed debris from our crawl space and set traps. They returned 3 days latter and removed two rodents and set new traps. Returned 5 days later, removed one rodent and set traps again. Returned one week later, no rodents, but left traps and "free food". Returned one week later, no rodents and "free food" not eaten. They will return in one month to check again. If no rodents, return in 3, then 6 months. Andrew and his staff are great to work with, and even though the return visits may sound like overkill, the reassurance from those visits make the modest inconvenience worth the time. Andrew and his staff are very polite and very careful when working in your home. I highly recommend them! Frank P. read more

First off the day I called Andrew he was able to come do an inspection that day which was amazing! We then scheduled the appointment for him to do the work!! We had Andrew come out to seal all entry points into our house and set some traps earlier this week. The day after he left we caught 2 more mice and since then there has been no more activity!! Andrew came out today and checked all the traps in the attic and garage and nothing! He will also be back next week to check again!! I'm very optimistic that our problem is solved! Not to mention the incredible price he gave us for everything!!!! I hope I don't have to use this service again but if I do I will definitely use this company! read more

These men are wonderful. My landlady had some other company come to my house a year and a half ago and they NEVER got rid of the rats. I called Andrew and within 5 minutes of him walking in the door he knew exactly where they were coming in from. The next day another gentlemen came and covered all the holes and set the traps. They have gotten rid of them. i would recommend Diamond Rodent Proofing to everyone. They are great. Thank you thank you read more

Andrew and his team at Diamond Rodent Proofing are efficient, professional and patient. After calling a bunch of services in SF that were too busy, Andrew responded immediately and agreed to come right away. Overall, great work and I would hire them again. I have already recommended them to other neighbors in SF. read more
