GMON delivered a detailed and comprehensive survey and topography map of our lot in Altadena after we lost our property to the fires, the survey team was very professional and courteous. After calling around to several local surveyors who were price gouging and take advantage of wildfire victims surveying needs -- I truly appreciate GMON Surveying and their fair prices. Especially as a construction and design industry professional, I can vouch for their services, they made the process straightforward and stress-free. Thank you GMON Surveying. read more

I'd like to share a very positive experience with GMON Surveying. Booking an appointment with them was straightforward, honest, and fast. Even the price was fair compared to the other quotes we've received. The firm manager, Monica, was awesome, professional and helpful. The survey technicians were nice, courteous, and overall professional. Even the office assistant who answers the phone is well-mannered. They are so professional, they didn't even disturb anyone unlike the survey company that my neighbor hired who ended up removing OUR wall (a wall that's ours and on our property which is there to keep our pet safe) without notifying us first. GMON, a company whose team presents themselves with professionalism and honesty is rare. I would 100% recommend GMON to everyone. read more

GMON is the most professional agent I find among all five vendors answer my request on Yelp. The price is reasonable, the filed team is very nice and professional. I think his name is Bruce, a very good guy. It took more that 6 hours to get the entire process done....I have to follow up with the final report after I paid the second half.....in general, I am happy with their job. read more

Gmon surveyors were great. Very professional and courteous from the very beginning. I had a couple of quotes, and decided on GMON due to the ease of communication and their pricing. They were pretty much within the range that I expected, based on some research for Los Angeles. They scheduled me at 8:00, and they arrived at 8:00. They were here the entire day, measuring my irregular block and area. They were so very nice, and very diligent with their accuracy, marking the areas they were able to mark, along with verifying the existing, and very old, markers on the sidewalk. I even found out that my neighbor has about 1/2 a foot of my property in the back, and 13inches in the front. It is a great relief to know where my property lines truly are. GMON did a fantastic job. I would recommend them 100%!!! read more

I recently hired GMON for a boundary survey during a repaving and fence repair project. Although my family has owned the property for years, a neighbor recently questioned the property line for the first time. To resolve this amicably, we chose GMON based on their excellent ratings, fair fees, and responsiveness. The firm was highly accommodating of my tight timeline. The manager, Monica, was gracious in explaining the legal process, and the field crew was prompt, professional, courteous and knowledgeable. The results were thoroughly explained. I highly recommend GMON for any land surveying needs. read more

I lost my home in the Eaton Fire in 2025 and needed a boundary and topo survey for my rebuild. I found GMON here on Yelp and was completely satisfied with the work and deliverables. Monica, the firm manager, was very responsive with communications. The survey was scheduled and completed quickly. The price was also very reasonable. Highly recommended. read more

We did not use their services,but GMON Surveying was very prompt on responding to my questions,informative with their answers,& very professional.I would not hesitate to call them if we did need to use a surveyor. read more

The team helped me with survey of my new property. Very professional and responsive. Will use again

Great Veteran owned business, great service, great employees, and they did everything they said they would do from start to finish.

The price was fair and the team was professional and nice. The results were thoroughly explained.

Needed a property boundary survey on a large hillside residence. Reasonable prices with fast response time.

Quoted $2,487.30 for a boundary survey 5/7/25. Quote said expires after 30 days. Now that it's August I realized I needed to confirm quote to proceed. Was quoted $4,840 for the exact same scope of work see pictures. When I asked Monica how this could be, she originally said the County's recording fees increased. They increased by $20... the scope of work increased by $1,619 while the description of the scope of work remained copy/pasted the same. When I pointed this out to Monica, she stated the surveyor priced incorrectly the first time. I asked for management to review and explain. I see on the May quote for the partial survey the recording fee must be incorrect since it's only $18 so there's multiple issues/mistakes happening besides the price gouging. read more

See all

GMON is as great at informing me on my surveying needs to meet my city's site plan requirements. Monica was very helpful and was very proactive. The surveyors were very professional and made sure they met all my specific asks, and their prices were very affordable. Highly recommended! read more

We hired GMON Surveying and they completed a satisfactory survey, to our specifications.

GMON Surveying surveyed my property a couple of weeks ago. The survey and whole interaction with the company was excellent: professional, accurate, courteous. They also gave the best bid of the various Surveying companies I approached. I highly recommend GMON Surveying. read more

I originally provided a 5 star review of GMON but after much thought and guilt about other's responding favorably to my review I've decided to share my true experience with this company. I hired GMON based on previous reviews but there were a few revealing ones that touched on a certain staff member who made their projects very unpleasant and difficult. I too ended up with a similar, if not more nasty and protracted, experience with one Monica Cabezas. From the beginning my communication with Monica was doomed when she misinformed me until the 12th hour that my presence at our jobsite (we were doing a fairly simple lot subdivision that required a survey, Slope Band Analysis and final survey report) wasn't required in spite of my concerns that access was limited due to a locked fence. After SEVERAL delays in scheduling due to her lack on communication I finally learned that my presence wasn't required and I was furious about the delay. I suggested we have a sit down with the surveyor (the owner) to discuss better communication moving forward. Her response: "If you don't like our services we can refund your money and you can go elsewhere". Very professional. Since I'm a detailed individual I started keeping a chronological history of my interactions with Monica. The most egregious one after much lip biting on my part to keep from receiving more of her ire (which came in the form of INTENTIONAL non-communication and shitty, terse responses) was a final map that apparently required a simple form from the city to finish the process. Our expeditor (that's a whole other story) and Monica never bothered to point this out. And when I queried Monica as to the turn-around time to complete the final map I was told "8 weeks". At 9 weeks (lest I "bother" or inflame her) I emailed to find out the status of our project to which she responded: " Oh, we haven't done anything because we were waiting for the form". I exploded in anger and subsequently printed out my chronological history of interactions with Monica and hand delivered them to their office to the attention of the Owner/surveyor. I received an email from the owner after the weekend apologizing and telling me my project would be handled quickly and that I would have a new project manager, Ally, handling our affairs. Fast forward to the ultimate survey being finally accepted by the city (it still required 2 revisions which, of course, slowed down the process) and a requirement of the surveyor (GMON) to place the monument settings. The surveyors came in a reasonable amount of time (I guess my presence was still not required) BUT they stopped short of completing their survey. When I asked Ally what the problem was she informed me that they (the surveyors) needed a clarification from the city as to how/where the setting were placed. Fair enough. But then I received an email that the scheduler had us rescheduled for the final survey in THREE WEEKS! I hit the roof, especially when I found out the scheduler was none other than MONICA CABEZAS! I insisted on a better date and was subsequently rescheduled for later that same week (go figure). Why, based on my experience and those of others who commented on Monica's lack of professionalism, she wasn't fired at this point is beyond comprehension. Anyway, the monument settings were finally completed and submitted to the city. Meanwhile, much to his credit, the owner/surveyor Jerry waived the 50% balance owed due to the aggravation and DELAYS (at least 3 months overall) Monica caused. And Jerry's work was excellent so I can't take anything away from him. BUT, if you want to experience the kind of aggravation and unprofessionalism I did ON TOP OF trying to deal with the city and other circumstances (don't EVER do business with the "expeditor", Pardo Land Management) then have at it. This is not an experience I would wish on ANYBODY! read more

They saved me thousands of dollars with a quick overview of my property, during a drop in visit. Surveyor pricing varies wildly. Shop around. It turned out we didn't need a survey, but would definitely come back here, if needed. read more

I cannot recommend GMON Surveying enough. This is an establishment that is professional and helpful from their representatives to their land surveyor field workers. I had the pleasure to have Fabian and Marcos survey my property and these two gentlemen were professional, informative and very respectful individuals from start to finish. They were punctual and finished their work in a timely manner and answered all my questions. GMON Surveying is also very competitive on price compared to others. I highly recommend considering this establishment for any surveying work. read more

Their pricing was reasonable and on par with the other bids we received. The survey we needed was simple - location and boundary. It took so much back and forth to get this completed. The crew had to come out twice and it took 3 drafts before we got what was needed for our permit supplement. Each step took about 7-10 days, so it took over a month to get everything done. I found every interaction with Monica to be incredibly rude and off putting. 2 stars because the survey was eventually completed, and they did not try to charge us extra. I would never use GMON again. read more

I was told someone would contact me after I contacted this company twice. Disappointing!

Attentive team answer questions & reasonable deal in surveying needs will definitely recommend!

Experience has been less than ideal. They do not deliver on their own deadlines, I've used them 4 times total and gave them the befit of the doubt each time for topography, slope analysis, plot plan and survey and though the work was completed it was always delayed 1-2 months. Example - "Hi Monica, we paid for slope analysis a month against, when will it be completed?" Response: "Hi, the surveyor said in 3 days" 2 weeks later: "Hi Monica, it's been 2 months since we paid for our slope analysis, when will it be sent to us?" Response: "Hi, the surveyor said you will have it by Friday" It's been 2 months, I'm still waiting for my slope analysis. Update: I got back my slope Analysis after 2 months. Did not require a site visit as they had all the calculations from a prior survey. read more

We did a lot of research and got three bids for a survey (first time) of our residential property lot. GMON was highly professional throughout the experience, and also happened to be the least expensive. As promised, they delivered a highly detailed survey within a few weeks (even over the holiday season). They were also very helpful in answering questions in person on our property after completing their survey work. (We have a pending development next door and wanted to know exactly where certain walls, fences, and trees are. They were helpful in pointing out exactly where the lot lines are.) read more

Immediate response when I requested an estimate for a survey of my property. They also followed up via email and phone to see if I had any questions. Very professional. read more

Very professional and organized. Got my residential land survey done with no issues and they did a great job of explaining my property boundaries, especially since I don't know anything about this stuff. Highly recommend! read more

The whole staff from this company really goes the extra mile to support your surveying needs. Ms. Monica, the manager of the firm, does her very best to coordinate the crews schedule with your schedule to accommodate everyone's needs. She's very thorough, the type of person that makes sure she crosses every "t" and dots every "i". Even her staff members compliment her work ethics and support she provides to them. If you're in need of surveying services, whether residential, commercial, or whatever your needs are, be sure to contact GMON first. read more

I can't speak highly enough about this Surveyor. Their professionalism, expertise and incredible customer service is above and beyond. They're also competitively priced and fair. We've had them come out on multiple job sites, and have always performed. Monica, the Firm Manager, is one best people I've worked with in this stressful industry. She's responsive and truly takes care of us -- has never dropped the ball. They're a very active firm, make sure to book them in advance and discuss timelines for your project. read more

Just made the final payment for the project. The whole thing couldn't have been easier. Our land is in a kind of historically old area and it was complicated to find the border lines and the guys had to come twice. They were different crews and both of them were very nice, on time, very polite and ready to explain to you everything step by step. I had bunch of questions since it's a complicated area and I wanted to make sure we are getting the right info and Monica was kind to explain everything to me. I never had any communication problems with them. Emails, phone calls, appointments, everything was great. Now to continue and start construction we have to do topographic map and slope survey and for sure I'll be using their services again. read more

Profesional and very reasonably pricing. Although I don't like that they want half the money up front but I am over all very happy with the project. Thank yiu read more

Company is very professional. They worked with me on a few change order. Monica is great. I will use their services again. Used them for two projects. Field crews are knowledgable. Drawings are sent in a timely manner. read more

Prompt in response. Was able to arrange appointment very quickly and they did a high quality job.

I was trying to find a good honest survey company for the issues I am currently experiencing with a neighbor. After SEVERAL Google searches and SEVERAL survey quotes I came across GMON. First impression...WOW! Monica and Alyssa (forgive me if spelling isn't correct) are very professional, courteous, and knowledgeable. I explained my situation to Monica, and she was able to provide me with a great deal of information. Their quote was VERY fair and very reasonable compared to other outrageous quotes that I have received from other survey companies. Monica mentioned that this company receives great reviews even if they are not used based on the initial contact with Monica and other staff members. I can understand why because I'm now one of them, and we will be using them. I'll let you know how it works out! read more

I love sharing 5 star reviews for businesses or services that deserve it (would vote higher if possible). GMON Surveying is one of those companies, and is very highly recommended for any and all professionally licensed surveying needs. In my case, I needed a Topographical/Boundary/Slope Analysis for my new construction residential building project, and they exceeded all my expectations. Save yourself much of your valuable time and call them first. After I had gathered estimates from 5-6 surveyors throughout So Cal., GMON was far & away the best price, the others wouldn't/couldn't come close. Jerry, Monica & the rest of the team will take care of you guaranteed. Tip: They are busy and in demand (with good reason), so be patient. Keep up the great work you guys do. Thank you Jerry! read more

Call me crazy for giving a 5 star review for a company i did not use, Gmon came very highly recommended from several different sources. I had an emergency situation needing someone out the next day , understandably they were booked a few weeks out . Regardless Monica called me back immediately, each time . She looked a bit into the property and tried to do what she could to help me sort this out . I certain could see this company Priority is helping people and being kind first and for most ... that is worth a 5 stat rating in my book ! read more

And I'm back. Used this company for the 3rd time now. Multiple locations. Excellent customer service! All and all, a simple process to get on calendar. It's Monica who sets the tone. Her professionalism and patience had me on day one. I wanted a specific area and retaining wall included and she was sure that was defined in the quote/instructions. Rates are fair. Highly recommend this company. ***Can't forget to mention the crew Dave and Alexis, for the warm hello when they arrived and their professionalism. read more

I needed a survey for a pool build and GMON had the best prices out of all the people I called. Their crew was very professional and they were at my house and neighborhood 4 hours to do the survey. It will take a few weeks to get your hard copy of the survey report after the survey has been done. read more

GMON Surveying has been a pleasure to work with. We needed a boundary survey done and they were so helpful. Monica is so responsive and knowledgeable , she was willing to answer any and all questions we had. The surveyors were super professional and just as helpful with any questions. They were punctual, attentive, and very friendly. Their pricing is also very reasonable compared to competitor companies around the area. Would highly recommend their services! read more

I needed a survey for a construction project on my large residential lot in Eagle Rock. After reaching out to quite a few firms, I went with GMON because of the good reviews, favorable fees, and their local presence. The surveying crew finished in just a few hours and my final product is a detailed topographic map and survey which was exactly what my contractor needed for their work. I would have given 5 stars but I was told the final survey report would be ready in two weeks but it turned out to be four weeks. It wouldn't have been a problem, but I had to follow up myself to check in on the status. Would've been nice if the communication was a bit stronger. Wish i could give 4.5 stars instead of 4! But at the end of the day the final product was very good. I would recommend using GMON for your survey needs. read more

These guys are tops. Lowest bid compared to other Yelp Friendly and on-time crew Easy to communicate over E-Mail and pay on-line Easy to schedule; ~2 weeks for survey then ~2 weeks for map read more

Really good dude, Jerry. Best price I could find for a survey and did a great job. Exactly what we need in a guy who used to work for a "big" firm and then went out on his own. Some of these other places wanted an arm and a leg. Like, three-four times (thousands of dollars) the amount as Jerry. I couldn't believe it. For a f*cking boundary survey. I'm like, yeah, no. You should say "yeah, no" too and go to GMON. read more
