This is probably the best pest service we've received since moving here in 2010. Very professional, on time, just all around perfectionists. [[HIGHLIGHT]]Very satisfied THANK YOU ROBERT G. You're awesome![[ENDHIGHLIGHT]] read more

Cornerstone is great. Haven't seen any pests. [[HIGHLIGHT]]And staff is very very kind.[[ENDHIGHLIGHT]] They come out every other month to spray my house. Price is reasonable. read more

We had spiders and critters around our house. With summer coming up we were concern for our grandchildren running around the pool bear footed [[HIGHLIGHT]]We contacted Cornerstone and spoke to a gentleman name Ken. We explained our situation and concerns with spiders and chemicals around the children and our plants. He was very knowledgeable and explaining his product.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]We schedule that was so easy and got quick feedback for scheduling.[[ENDHIGHLIGHT]] The tecks came out and were very professional. they were very detailed on knowing were those dam spiders hid under. they cleaned all the webs etc. I was very happy with them. Very nice guys. I'm retired so sometimes I like to talk to much and keep them from getting done. Sorry about that fellas. I'm a. chatter box. Good people. I highly recommend them. [[HIGHLIGHT]]My advice if you need information contact the Person that help us . His name is Ken[[ENDHIGHLIGHT]] read more

We have had cornerstone pest control for almost 15 years. We are so happy with their service. [[HIGHLIGHT]]They always call before they come out and when they leave I don't even know that they have left.[[ENDHIGHLIGHT]] We do not have any problems with pest since we've had them. I highly recommend them read more

Service was terrible. Would not recommend. No snail bait and areas they would not treat.

[[HIGHLIGHT]]Great service! Cornerstone has great customer service and overall product.[[ENDHIGHLIGHT]] Im sure they told me what they use but honestly idc as long as the bugs stay outside and away from my house keep using it. LOL [[HIGHLIGHT]]everything has been great even referred my father in law same great service there as well.[[ENDHIGHLIGHT]] read more

I have left a review before but wanted to add some things to it. To go along with the awesome service I've documented before I wanted to add that they don't charge by month like most pest services do, the charge by actual service trip. In the winter when service isn't nectary they will come every other month so instead of being charged 12 times a year I am charged 9 to 10 times a year, only when I'm serviced. Also ifI have some specific need ( I've had some ant issues) they will give extra attention to it no charge. These guys are awesome. read more

I was charged a fee for notifying them less than 2 hours before the scheduled appointment time, yet they have never informed me the time of service. They violated their own contract. They only call the day before they come out. They only leave message if you don't pick up. They do not give you opportunity to confirm. Their product may be good, but the way they schedule is really bad. They refused to refund my late fee. Filing complaint with the state and sending a demand letter. Will see what happen? I don't normally write review and but I have to take time to do it this time because I am so pissed read more

I've had Cornerstone Pest service for over 2 yrs now and continue to have excellent results. [[HIGHLIGHT]]They are very flexible in scheduling service and providing additional help with those pesky bugs when we need them![[ENDHIGHLIGHT]] They service once a month and do a thorough job. I highly recommend this company! read more

[[HIGHLIGHT]]I was really impressed because there was no holding. They answered the phone promptly.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]Got everything set up to start my service Wednesday.[[ENDHIGHLIGHT]] Looking forward to doing business with them for many years. read more

My recent experience was truly disappointing. Despite being a loyal customer for over seven years, this year, I faced severe pest issues both inside and outside my home, which was a first-time occurrence since I've lived here. While I had never required extra services in the past, I was initially unconcerned because re-service was an included benefit "supposedly" ;However, I soon discovered that is not part of the wonderful service they claim to offer. Before scheduling my service last month, I inquired about available options to address the problem because it was getting out of control. They suggested indoor service, but with five animals, this was a difficult choice as we would all need to vacate the premises for 4-5 hours. So, I decided to research if outdoor cleaning would be effective. It seemed promising, so I hired a company to power wash my house, spending $1500 in hopes of eliminating pests settled in areas I can't see. Unfortunately, I still had a few issues, but great news was it was particularly only in the backyard. Frustrated by the ongoing problems, I reached out to Diane at Cornerstone to schedule a service and get the situation under control before it worsened. To my surprise, she made me feel it was my fault because I didn't do indoor service but that was option not mandatory so if I needed a extra service I'm now charged an additional $54 charge(I've attached her email) I couldn't help but feel that this was misleading, especially given my months of complaints about spiders and ants and her response not to worry it is covered until it is under control. This experience left me deeply dissatisfied after years of loyalty. It is just sad how many companies don't care about loyalty from us in a time where the economy is so bad that we work hard for the luxury of even wanting pest free homes. JUST SAD! There is so many companies so now looking for one who will appreciate my loyalty. read more

Cornerstone Pest Management - Email saying I would be charged extra when this is a covered service with bimonthly service. - Pest Control Near Me - Modesto, California

See all

[[HIGHLIGHT]]Can't believe how quick they responded to my request.[[ENDHIGHLIGHT]] Price was in line with my last company. Tech actually talked us out of the indoor service as he felt it wouldn't be beneficial. Could have easily taken my money and just did it. Only complaint I have is it's been 1 day since the spray and we have dead bugs EVERYWHERE. lol. Highly recommend. read more

[[HIGHLIGHT]]Very helpful with the process of getting service started.[[ENDHIGHLIGHT]] Patient, informative and transparent in the pricing. I am looking forward to working with this company. read more

I had the nightmare of finding red ants all over my kitchen and bed. With little kids and biting red ants, I could not wait days to get the house sprayed. [[HIGHLIGHT]]Cornerstone got me scheduled for the same day and took really great care of me.[[ENDHIGHLIGHT]] He sprayed inside and outside. He also gave me a few ant baits in case they came back but I haven't seen an ant inside since. Highly recommend! I signed up for regular service to avoid this happening in the future and it is money well spent. read more

I yelped several different pest control companies. [[HIGHLIGHT]]Cornerstone was quick to respond.[[ENDHIGHLIGHT]] After meeting with a few of the companies for estimates, I decided on Cornerstone. Are they the least expensive? No. But the knowledge & integrity sealed the deal. Ken & I walked my property. I told him my concerns & he told me his plan of action. [[HIGHLIGHT]]I called the office to set up the service & Christy (I think that was her name...I apologize if I'm wrong) was very nice & very professional.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]She made my appointment for the next day.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]The day of the appointment Ken called and asked if he could come earlier than expected.[[ENDHIGHLIGHT]] We took care of the service agreement & he got to work. He was very thorough & was happy to answer some questions I had. I know it's only 1 service, but I'm really happy I went with Cornerstone. read more

I have been a customer of Cornerstone Pest Control since 2018. I appreciate their professional conduct and the ways they go above and beyond as a company. They not only take care of the black widows (YUCK!!!) in my yard but they sweep the cobwebs away. I had never had a pest control service do that before. They are also very conscientious and call the day before the service to remind you. I am very happy with their company and will continue to share my good experience with others. read more

We have used Cornerstone Pest Management for many years. We had problems with ants in our yard, we were told by one of those other companies it's because there are orange trees in your yard. Well Stephen one day came around asked to give his company a chance, he could help! Since that day we have not had a problem his customer service is the best and we have referred all our friends. Thank you Stephen. R. Ricker read more

I don't recommend this company for pest control service. Cancelled after 1 year service agreement. [[HIGHLIGHT]]Poor customer service, difficult to schedule/reschedule, over priced, and dishonest.[[ENDHIGHLIGHT]] Will never use again. Strongly don't recommend. read more

We've been with cornerstone for a few years now and I never thought I'd see a pest company as "need" but these guys are awesome. Just recently I had a wasp issue in both our basketball hoop and under the hang of our house and they addressed it the next day (I called on a weekend) and they came by and within 10 minutes wasps were gone from them spraying. No charge for the wasps. They've even came to service when my dog was in the back, since we'd forgot they were coming, and he's a pain in the butt! Really great company and great pricing for what you get. read more

[[HIGHLIGHT]]From the prompt return call for service sign up, to the professional office staff and technicians, I am satisfied and will continue to patron Cornerstone Pest Management!!!!![[ENDHIGHLIGHT]] read more

Yeah I hate bugs or critters of any kind. I think everyone does. Thankfully Cornerstone has eliminated this issue for our family. We've used them for over a year now and have had zero issues with ants or water beetles like we used to. They know their stuff. The technicians are always friendly and thorough. You can tell they do an efficient job and we never feel as if the service is rushed. I'd recommend over any other pest companies! read more

I just put one start because this system does not allows you to review without at least 1 start, but in reality they deserve ZERO STARTS!... Customer Service is horrible!!!... starting with this woman who answers the phones in the office I believe her name is HAILEY, She is very rude! I paid for 6 services, Their service didn't really help with the problem that I had at home (Spiders, Mosquitos, Fleas, ETC.) Also, they scheduled you whenever they want, not when is convenient for you! I had a service scheduled last week by them, but I have to call and ask them to cancel this one, because I have a small dog that stays in my backyard when we are not at home (Of course is an outdoor service), and no one could take care of my dog that day. I told her that I will call back to rescheduled sometime this week. last night I received a call from them, it was an automatic REMINDER that they will come to my property TODAY, I called back and left them a voicemail (Because they never answer the phone when you call) asking for the time that the service will be done, because of my dog, the woman at the office said that will be between 11am to 1 pm. I told her that this time would not work for me because is late and I have to work too, and since I always request my services very early in the morning and this one that they scheduled me was on their own convenience (Not mine who is the person paying for the service)! and it was without consulting me the time. I try to explained to this person that I have a dog and they just can't access to my property whenever they want, so her answer was: This is your last service contracted with us, and because I never call to reschedule, they did it for me. (Basically, they work this way... Whether I agree or not they will do it) and because is almost the end of the month... Oh excuse me! you still have few days left on June... WOW!!! Even do I a explained that neither my husband or me can be at home to take care of the dog, they just scheduled you without asking if the time or day works for you?!!!!! Cornerstone Pest Management, You guys are way to much!!! I'm extremely disappointed and unsatisfied with the service provided by them, and as I mention before starting with the people who works in the office HAILEY! I normally don't take the time or like to write any reviews for business unless the service or product is good. But, people needs to know also the bad stuff (Which in my experience with this company, I have nothing less than a horrible experience and on top of that I just waste my money) I will never use their services again! WASTE OF MONEY AND TIME!!!!!!. and NO, I don't recommend them. I also want to make clear one thing! My review has nothing to do with the technicians who did the services at my place, I have nothing bad to say about them since they where always very polite with us. read more

I have used this pest management service for nearly 10 years. They are very professional, thorough, and courteous. I particularly appreciate the care that they take in using the right amount of deterrent to manage pest issues without going overboard. In sum, they keep the bugs out our living space, but leave a healthy yard for plants and animals to enjoy. read more

We have been using Cornerstone Pest Management for many years. They have been very reliable, efficient and they provide excellent service.

We highly recommend them to anyone who needs pest management service. read more

I've had Cornerstone for a few years now, I've always been very satisfied with their service. The year we had a lot of 8 legged friends take up residency in our back yard they came out multiple times to evict them. They show up when they say they will, and are very knowledgeable about pest issues. read more

We have used Cornerstone for over 10 years and have been totally satisfied by their awesome service! The techs are very knowledgeable and always ask if anything is needing extra attention. We always know the day before when they are coming and it's easy to reschedule with their courteons office staff! Would highly recommend! read more

Cornerstone has been handling my homes pest control needs for 7-years. They notify me in advance of their visit and show up when promised. I recommend them very highly. read more

I have been with Cornerstone Pest Management since moving here in 2000. I have been very happy with their service. Alway, reliable, on time and listens to instructions about not spraying near my lizards on the back fence!! Alway easy to move and reschedule my appointment if necessary. Office workers are AWAYS helpful and friendly! Their pricing is reasonable and the owner in always there if you have a specific or detailed question.

Very happy with their service and would recommend to anyone looking for a new service or just looking to replace an old service that's not working well for them any long. IMO you won't regret moving your pest service to Cornerstone Pest! read more

I have had Cornerstone since the day he rode up my sidewalk on a segway to introduce his business. Couldn't be happier. No surprise billing increases, always pleasant, thorough, and professional. They are mindful of my needs and have come out even late at night to stop an influx of mice. I wouldn't consider any other pest control service. Louise M. read more

I can't say enough good things about this company. I've been with them for awhile and have never had an issue. The office ladies are the absolute sweetest! I HATE spiders, and every summer when we get them inside due to the heat, I call and ask if they could spray the inside and I always tell Diane and Chantelle how much I hate spiders, etc and those two just listen to me vent about bugs (my husband likes to remind me they're not a therapist for me haha) and are just so sweet and understanding about getting someone out to the house in a timely manner for me. The guys that come out and spray are always super cool and verify any insect issues we may have and make sure we have everything taken care of. Love this company! read more

New to service, but [[HIGHLIGHT]]did a great job listen to all my request very friendly and on time[[ENDHIGHLIGHT]] .

We have been customers for several years after trying to do our own pest management in our home. Cornerstone is always very responsive to questions and concerns and updates us frequently with any schedule changes. Pricing is competitive - I also appreciate the option for bi-monthly service - most other companies only offer monthly service. The technicians are always friendly and efficient and want to help solve problems with minimal disruption. Great company! read more

Called for no-monthly preventive pest control and they came out the next day. Our technician Ken was very friendly, informative and professional. He pointed out a few issues we didn't even know we had and talked with me about how he was going to address them. Also, love supporting a small local business. They were one of the more affordable options from the dozens of companies we called. Can't recommend enough! read more

Overall extremely satisfied and will continue to refer them to others looking for pest control services here in the area. read more

The office staff is always very accommodating and friendly in setting up or changing appointments.
