West Valley Arborists - Redwood trimming: before/after. - Tree Services Near Me

They did a wonderful job with our trees. They did almost everything to spec the first time. When we reached out about a small discrepancy, they came back to fix it, no hesitations. Everyone was professional and friendly, from start to finish. We would gladly reach out to them again next time. read more

Fantastic experience with West Valley Arborist! They handled both the tree removal permit and the safe removal of a 60' redwood in a very tight space--all at a very reasonable price. I had a redwood tree in my backyard squeezed between two buildings, causing issues with the sewer line and foundation. The situation was tricky--not only did it require careful planning for removal in a confined space, but also navigating the city's permit process. Out of several quotes I received, Simon's proposal stood out. He recommended using a crane for safety, and his price was very fair. Heather was amazing in managing the permit application--she clearly knows the process well and stayed on top of every detail until it was approved. On removal day, the crew was outstanding. The foreman arrived on time and prepared everything carefully. The climbing arborist skillfully pruned and dismantled the tree piece by piece, while the crane operator safely lowered each section to the ground. The entire process was smooth, professional, and safe. When they were done, the site (and even the street) was spotless. West Valley Arborist is truly a 5-diamond star company! I feel very fortunate to have chosen them, and I wholeheartedly and without reservation recommend their services! read more

Very pleased with West Valley Arborist. Crew is great - respectful of property and does an excellent job with the trees.

Outstanding arborists! My beautiful Jacaranda is very healthy, so it gets bushy and overgrown very quickly. It's also in a rather small space, so it often needs trimming. I've watched others work on it, but this time I was able to see everything Rodrigo and Jaime were doing from my office window. They work quickly and confidently, and it's clear they know exactly what they are doing. The result is a very balanced and beautiful tree that will produce many more lovely purple flowers in the spring. Thank you, guys, you are wonderful and I'll be calling you again soon! read more

They have taken care of our insanely tall palm tree, removing dead fronds and trimming the trunk as needed. They did it soon after they gave us a quote and with minimal disruption of our tiny street. Overall, I really appreciate it. read more

We had a fantastic experience with West Valley Arborists Tree Service on September 12th, 2025. They trimmed ten trees and removed one dead tree from our property, and the entire process was smooth and professional. Simon, the owner, was incredibly helpful--he walked us through every step beforehand and made sure we understood exactly what would be done. The crew arrived on time, worked efficiently for about four hours, and left our yard spotless. What really impressed us was the combination of quality, communication, and value. The team was courteous, well-organized, and clearly knew what they were doing. The pricing was very reasonable for the amount of work completed, and we felt confident in their expertise from start to finish. We'd absolutely recommend West Valley Arborists to anyone looking for reliable, honest, and top-notch tree service. read more

Excellent service! Thorough consultation and great tree trimming. The workers were professional and friendly.

The whole process from getting a quote to the actual work being done was as simple as you'd want it to be. We scheduled the work after the quote was sent, the pricing was well within reason of what we were looking for. The crew showed up on time, were absolutely professional and courteous to my girlfriend who was at the house at the time. I was sent pictures of the finished work and was really pleased with their work, their level of responsibility and care to cover the driveway with plywood to keep any branches from potentially damaging the concrete as well as the clean up being spotless. I would highly recommend West Valley Arborists for any of your tree trimming needs, I will definitely be using them again for any tree related work I will need in the future. read more

The arborists from West Valley Arborists recently came out to my home in Sunnyvale and removed a problem tree that was in the backyard. They were very pleasant, hard working, and did a great job in removing the problem tree! I highly recommend this company! read more

Highly recommend West Valley Arborists. We had an 80-feet tall redwood that needed to be removed. It was located in a very inconvenient spot right between the two houses and occupied all of it. We were very concerned about the whole tree removal process because so many things could potentially go wrong. But everything went very smoothly with Simon and his crew. They were well-prepared for the job. They arrived on time, worked swiftly, had all the necessary equipment, and it was evident that they were experienced arborists who knew their craft inside out. When the job was done, they left our property spotless. Excellent work. read more

I am happy to give West Valley Arborists (Simon) a well deserved 5 STARS for the removal of (3) trees in my yard - a badly damaged pine tree (60'), a camphor tree (25'). and a palm tree (25'), The men that did the work, Daniel,Mario, Naze, and Omar worked seamlessly as a team and were skilled at what they did. They not only worked hard but they took pride in their job. When they were finished, I couldn't tell that they had been there, other than I had (3) missing trees. I highly recommend West Valley Arborists and would absolutely use them again. Sharon Coburn read more

West Valley Arborist did a beautiful job on pruning my fruit trees and Japanese maple trees. All of my trees now are beautifully shaped and ready for spring. Thank you for your expert staff and highly trained technicians. read more

i've been a wva customer for many years. this year i met with simon, the owner, before ordering the annual trim of my 40-year old olive tree and pleaded with him to do a drastic cut back of this now over-sized tree in my postage stamp size front yard. he cautioned that the result might not be esthetically pleasing but that he would personally direct his crew and do the best job possible. the result was fantastic. the tree hasn't looked this good in decades. i cannot recommend this local firm highly enough. read more

I've been looking for a good arborist for a while and finally found it with West Valley Arborist. They did a great job and listened to what I wanted done. Crew very respectful of my house and yard. Will definitely use them again in the future. read more

I am very pleased with the professional work of this fine company! We got off to a bumpy start with two weather related cancelations. Yesterday was the big day. A ultraclean red truck and matching chipper arrived exactly on time. A team of 5 gentleman stet up safety cones around the equipment at the curb. The foreman Daniel had me show him the site and get my final input on the project, which involved a neglected 70 foot tall ash tree, and a 30 foot rubber tree. I left for work, and upon my return, I was greeted by the symmetric beauty of those two professionally groomed trees. The surrounding yard was cleaner than when they arrived, with no clue as to the massive operation that had occurred there. I would like to thank the people of this business, from the wonderful lady on the phone, to the brave tree specialists. I can highly recommend West Valley Arborists. read more

Extremely disappointed at this consultation to assess a downed eucalyptus tree in los gatos. I had requested an arborist consultation to inspect the tree and determine the actual condition of the tree to help determine factors contributing to its falling. He told me the general factors that may have contributed to the tree falling and did not see to care much to actually inspect the tree itself in any detail. We had walked down to the tree and in literally less than 3 minutes we walked back to my house and he got into his vehicle and left. No additional observation of the tree in question and stated that a written consultation consultation can be anywhere from $600-$1000. Paid $250 for some small talk, general conversation about eucalyptus trees which is readily available and less than 5 minute on site evaluation of the tree itself. And I had to ask for a least something in writing to document the visit and tree in question. This , I thought, would be customary when a company comes to evaluate or assess something ( this is aside from a more detailed lengthy written summary). I called the office and they did state they would provide something in writing but this is not customary ( he said that also) and it seemed as is if I were demanding more than they felt they should provide. And unfortunately what was provided for $250 was less than the bare minimum and provided no additional information about the tree. And they called the day before for the payment BEFORE the visit. Very, very disappointing and sub par service from the owner and certainly not worth $250. read more

Simon and his team at West Valley Arborists deserve a great review. The office staff is efficient, reliable and friendly. The on-site team was easy to work with. They skillfully performed the work and did an excellent clean-up job afterward. read more

In response to Simon's comment on my review: Respectfully: you're dodging, Simon. (1) You say: "The trees were in fact excessively pruned / topped some years ago, and have been growth-managed to improve the hillside view for a long time. To be clear, this took place long before we were invited to service these trees." True. Which is why we were concerned about excessive pruning/topping. (2) You say: "Our client requested, the neighbors (who posted the review) agreed and we performed selective pruning of the new growth back to the previous heading cuts/predefined structure (performed by others in the past), to again, enhance the view but within acceptable practices.   Additionally, in further support of the trees' health, we removed some deadwood we encountered ~ only that of completely dead tissue." Untrue. We, the neighbors DID NOT AGREE to haloing the trees. In fact, my husband told you, Simon, that he agreed to have the work done ONLY IF YOU DO NOT HALO THE TREES. We can debate terminology (haloing, topping, whatever) but the fact is that at least four of the trees you cut no longer have any canopy. If you judged that the trees could not be 'growth managed' this time without haloing, you should have said so. You did not. Bottom line: you haloed the trees, removed the canopy, contrary to the agreement. (3) You say: 'It is worth noting that the posted picture only represents 2 of the 11 trees we serviced and is among a hillside full of untouched Coast Live Oaks presenting similarly.' Okey-doke, below is a wider-angle photo of the trees you 'growth-managed.' These were among the ones most grievously haloed. There are no other 'untouched Live Oaks' on the hillside presenting similarly to what you did. (4) You say: "Regardless, we pride ourselves on prioritizing the health of the trees we care for." I wish you had. read more

Called to have someone come out to do tree removal estimate...made appt for 2 weeks later. They said that was the earliest they could come out (had a few other companies come out the same week we called)...but ok. They called a few days or the day before (not exactly sure) to confirm the appt. said we didn't need to be home since the tree was on the street and already tagged by the city. We were home the day and time they were supposed to come out...no one showed or called...no estimate dropped off either. So not sure what happened. read more

This is the second time I have worked with this company. They are always very responsive and helpful. I had a tree come down in our yard about a month ago during a huge storm. Despite the storm, Simon came out the same day I called. Unbelievable! They returned later that same day to remove the tree. Also unbelievable! You can tell these folks really know their stuff. They are responsive, professional and honest. read more

West Valley Arborists already has a lot of good reviews, deservedly so because as arborists they do a fantastic job. I'm writing this review because their customer service is outstanding when things don't go as planned. And that is much harder to come by. Long story short, there was some miscommunication around removing a neighbor's tree and part of our garden bore the brunt of it. West Valley Arborists could very reasonably have left it to be our problem. But they didn't. The entire ordeal wasn't much of an ordeal. Heather was fantastically patient and eminently collaborative. She took every opportunity to hear our concerns and was empathetic to our situation. It always felt like we were working together to solve our problem and never that we were at odds. In a 2020 that has been headache after headache, I am deeply grateful that Heather was the person we got to work with. I would hire West Valley Arborists again in a heartbeat. As should you. read more

I recently used WVA services for pruning an overgrown Ash tree in my backyard. Because of the location of my property they had to do the job from the neighbor apartment complex at the back. Heather from WVA was very helpful in working with their management team, providing them all the necessary documentation to obtain the permissions. The working crew arrived at the scheduled time and date. They did a great job and they cleaned up afterwards. Overall it was a great experience. I chose WVA because their cost was very competitive and the professional demeanor of everyone I interacted with. I would definitely used their services again. read more

This is the second time we have used West Valley Arborists. Simon and his crew are very professional, respectful of our property, and do a great job in keeping our trees and fruit trees in good shape. We have recommended them to our neighbors, who have als o had great service from Simon. read more

After interviewing several professional arborists, we selected West Valley based upon the extensive knowledge and detailed proposal presented by owner Simon Tunnicliffe. He went out of his way to explain all of the problems noted in connection with the two sixty-year-old trees (one top-heavy; ladled with dead wood Siberian Elm and one bark beetle infested 100 foot tall year old Pine) standing on our residential property in Portola Valley. The crew of 6 arrived on time with all of their extensive equipment and trucks. Three men worked the hillside Pine, thinning it out and removing dead branches and branches hanging dangerously close to the residence. read more

West Valley Arborist did wonderful job on our oak tree. It looks amazing and we get complements eryday. They were very professional and took their time to do best work. We would definitely use them again in future. They did all the trimming of the huge tree, clean up and deep roots watering. Super happy read more

Specializes in Deceit I asked the owner to write a Arborist's Report on a tree because it had been dropping limbs and I wanted the city to remove the tree. The owner came out to look at the tree and I described the problem. I then hired him to write the report. After charging over three hundred dollars the owner wrote a report saying the tree was fine. Of course, I expected the owner to report is honest professional view. The deceit is that he clearly knew his general conclusion after seeing the tree but refrained from telling me until after I contracted for the report. read more

What a great team Simon and his crew are. I've used their services twice now, once to remove a very wide diameter and old dying tree in my front yard and replant a new one. A big team (all of whom coculd be on with lots of heavy equipment arrived, protected the grass and shrubs, worked safely (even from the cherry picker) and did a fabulous clean up job. Most recently Simon came to give me a quote on what I thought was a dying tree in my backyard that had a HUGE canopy providing shade over the patio. What a wonderful surprise to find out his crew could thin it out, top it, and it would last for a few more years. I highly recommend West Valley Arborists for their professionalism and courteous friendly workers and beginning to end customer service. read more

Simon came out to provide a quote to trim a large tree that the city planted, but as I've come to understand, is my responsibility... Simon provided the most comprehensive information of any arborist (I shopped two others). His knowledge - and as important - honesty, were VERY appreciated. While WVA is a tad on the higher side (compared to other tree trimmers), the old saying, you get what you pay for, definitely applies here. And I'll take WVA's licensed and competent arborists -doing a job right, the first time - any day over cheaper service providers. That's why I'll be calling Simon and WVA back in the spring to do the work he quoted. read more

WVA did an excellent job on my large Chinese elm, Liquid amber and medium size Pittosporum today. Simon and his crew's thinning and shaping all three trees was absolutely superb. The crew also arrived on time and did a thorough job of debris removal. A five star performance! read more

I had a magnolia that had been severely trimmed by the previous owner of the house. So severely it looked as if it was dying. Rather than continue to hope that it would recover, I decided to find an arborist. I had never used an arborist before and I was really nervous about finding a good one. After reading the reviews here on yelp I decided on WVA. Simon came out and evaluated the tree and confirmed my suspicions. The tree was dying and I had two options. Wait 10-15 years to see if it recovered or replace it. Simon was quite professional and didn't try to push me one way or the other. I really appreciated that. Within 24 hours I had a quote from WVA. I called one other company for a second opinion. Needless to say the experience with them was lackluster, but they told me the same thing, but their quote was a couple hundred higher for the same job and the person that contacted me was far less professional. Making WVA the obvious choice. Fast forward to tree removal/replacement day... Simon and his crew removed the dying tree and replaced it with a beautiful new native oak. I was pleasantly surprised how little, if any, damage there was to the surrounding sod. They also planted a smaller citrus tree in the backyard. Not only did they put it exactly where I requested it, they replaced the weed cloth and mulch around it. They arrived promptly when they said they would and I came home to beautiful new trees. They did a wonderful job on both trees. I waited a few months to post my review to ensure the trees would survive. Both trees are doing quite well after a couple of months. The Lime tree has golf ball sized limes on it already. I can almost taste the future margaritas. read more

Had a tree near the street that was dropping branches. Definitely a liability to cars parked and folks going for a stroll. Called for a free quote, received a competitive quote and decided to schedule a date for removal as well as trimming three other trees. Crew of four came out, did a great job, completed the tasks and cleaned all areas prior to exiting. Great experience! read more

West Valley Arborists recently trimmed two large trees in our back yard. Everything about our experience with them was exceptional. The front office is extremely easy to work with, the crew arrived on time and was finished earlier than they had projected. They cleaned the yard and roof completely and took great care to protect our koi pond and solar panels. This was the second time we have used West Valley Arborists, and I can't think of using anyone else again. They do what they say they will do, are easy to work with and really care for the health of the trees. read more

I used this service ~ 3 yrs ago for trimming our rather large Magnolia and was very happy with the results. This time around (October 2011) i was much less satisfied. The job quoted and completed did not coincide, in my estimation. While the tree is healthy, I felt better care could have been taken overall. Regardless, I paid the bill in full. To avoid misunderstandings, be very clear with your expectations and what you mutually agree to - with any service provider. This is a revised review - previous version was heavy with details better kept between myself and the service provider. read more

Love Simon and his company.Him and his men did a great job last year taking care of some trees on the property and his treatment recommendation for our fruitless olive tree, which turned out not to be fruitless after all. Called back for the recommended treatment this year and for some additional tree work for us and the neighbor. Have not heard back on either inquiry. Removed a star for that reason. read more

I hired this company to trim four very large Oak Trees in my new backyard that have been poorly cared for by the previous owners. The company finished the job in two days, were clean and did a great job pruning the trees. Also, I should note they came in a couple thousand dollars less than a competitor. I also liked that the owner of the company did the bid and checked in on the job site each day. I would hire them again and would definitely recommend them. read more

This is the second time I have used Simon and his crew. Both times the work was just excellent. I have a large ornamental pear with some fire blight issues that they have cleaned up without stressing the tree. I also have three queen palms and eleven Italian cypress that they cleaned up. The clean up of the debris is also excellent. Communication from the office wasn't so good. I accepted the bid, and waited for a start date. I had to call to find out when they were coming. I will certainly continue to use them for my tree work, as I like the professionalism of the whole field crew, and I trust them as certified arborists. read more

We had two of our Live Oaks cleaned out, shaped, and pruned. The trees look really good now, and the crew was very professional and do quality work. The quote and scheduling process was quick and we were able to get on the schedule within a week. Definately a well run business. Here are Before/After pics of one of the trees. read more

I called Simon after using Yelp reviews and ratings to find a Campbell arborist in order to assess the health and any work required on a very large camphor tree in the backyard of my Campbell duplex. He came promptly and gave me his recommendations about the tree's care and a quote for the work which I accepted. Within the hour his office called to schedule the work and Simon provided me complete information on notifying my neighbors and gaining their permission as the work would affect their yards. The work was completed perfectly yesterday and it was a big job. Simon and his team arrived 15 minutes early to assess the work area, greeted me and re-explained the process. Simon came back at the mid point of the job to ensure it's quality, progress and my satisfaction. With a tree off that size, there was a lot of debris, every bit of which was picked up from all 3 affected yards and even my roof/gutters were swept clean. The tree canopy still looks stunning from every angle, yet now light is able to shine through, all dead wood was removed and the tree appears well-balanced. I would urge anyone to invite Simon to bid for an arborists job on their property. read more

I was referred to West Valley Arborists by my real estate agent and had a wonderful experience with Simon and his team. With El Nino looming, I was nervous about the giant oak tree in my backyard crashing onto my house and / or damaging my neighbors' property since it sits in the corner. Setting up a consultation appointment with Simon was quick and easy and when he came out to inspect the tree, he put any concerns I had to rest. What I appreciated was the fact that he clearly knows trees and respects maintaining their structure as nature intended as much as possible while keeping us humans safe :) After all, they were here first. He was able to draw up an estimate on the spot and I scheduled an appointment with their office. On the day of the scheduled tree cutting, Simon and his team of 3 or 4 arrived early and we walked through what work would be done. While I was not able to stay and watch like I had originally planned, I got home by 2pm to find that they were wrapping up and getting ready to leave. Oh and the tree itself? Loved it - I get so much more light now and the tree looks like it can "breathe" again. New year, new tree. Kudos and thank you to Simon, Eduardo and the rest of the team! read more
