Gary and Diann Allen decided St. Charles County needed an Allen's Tree Service Inc. in 1978! Gary and Diann Allen launched their business from their home in St. Charles, MO and grew it into the leading tree care service in St. Charles County with integrity and quality. It was quite a struggle in the beginning and they were not sure if they would make it past the 80s big hair era but their determination and pride would not allow them to fail.
The most important qualifications a tree care company should possess are education, experience, and insurance. Our employees are well trained in accordance with OSHA (Occupational Safety and Health Administration) and ANSI (American National Standards Institute) standards to perform tree service ensuring the safety of our employees along with the health and protection of your trees.
Allen's Tree Service Inc. has 3 to 4 tree crews operating at any given time consisting of as little as 2 employees with a chip truck and chipper up to 6 or 7 employees with several pieces of equipment and trucks depending on the scope of work estimated. Our crews are highly trained to industry standards with over 100 years of combined experience.
Step 1: Contact our office for an estimate. One of our secretaries will set up a day and time for an estimator to come out to your house and meet with you to look at the issues your trees and shrubs may be having. Step 2: Then the day prior of the estimate a confirmation call will be made with a 2 hour estimated time frame of when the estimator will be out to your house to provide an estimate.

Allen's Tree Service was great! They removed our diseased ash Tree while we were at work. Came home to find not only Tree removed exactly as discussed without any debris left behind anywhere. Will definitely use this service again as need arises. Service: Tree removal

John from Allen Tree service came out and identified that my boxwoods were infested with leaf miners. He took time to show me how the insects were infesting the bushes. He was knowledgeable, kind, thorough and professional.

The crew from Allen's Tree Service completed the job on March 25, 2022 and I am very pleased with the work. They did a great job. I had them remove two trees, a large Cleveland Pear and a small Crab Apple. They ground both stumps and also trimmed two other trees. They cleaned up the mess and hauled it away. The crew was friendly, polite and professional. I am very happy with the service I received from Allen's Tree Service.

Woman on phone rude saying they wouldn't do job. Mis- referenced my legal rights to trim neighbors tree overhang. At my insistence a man came out who said they would be liable for tree rot 15 years from now. Brown and Croupen lawyers say Allen Tree Service is wrong.

The workers were efficient, quick and cleaned up the debris very nicely. I am pleased with the 'new' look. They also answered my questions and followed any instructions I needed to give them. Services: Tree removal, Tree trimming and pruning

We've had Allen's out a couple different times now. The gentleman who came out was very knowledgeable about our trees. They provide great service and are easy to work with!

Made an appointment for between 11:30 and 1:30 to have someone come out and look at some trees to take out. Called at 1:25 and was told oh you are next should be out there shortly. Called again at 2:25 when I hadn't heard anything and was told "oh well I don't know how long he is going to be at appointments." Then why even give a time or at least have the courtesy and professionalism to call or text and let your customer know you are running late.

Allen's spray my Sweetgum tree (gumball tree) every year and do a great job. I see other trees in neighborhood that don't get sprayed and they have ugly gumballs all over yard and street and still have old brown gumballs still hanging on tree. Wish people could see my tree which has NONE. It is very affordable and can't beat the professionals that do the work. Thanks Allen's Tree Service!

We've used Allen's twice so far, most recently for removing our landscape bushes that had grown too large and previously for removing a damaged tree from our yard. They did excellent work and were very responsive. They will be the first call I make next time I need tree or landscaping services. Service: Tree removal

Our young willow looked sad after a recent wind storm but bracing performed by Allen's has its main leader standing tall again! John's skill and knowledge about "all things trees" is unsurpassed. We have used Allen's for decades for trimming, pruning, and removal. All jobs done with excellence! Service: Cabling & bracing

WOW George's crew was amazing! They did an awesome job getting high up and trimming the deadwood from the HUGE trees in my backyard! They were very professional, cleaned up the mess and left it looking better then when they started! I'm so impressed and will request them every time I need a tree trimming!

Allen's Tree Service removed a large sweet gum tree in my yard, ground the stump and took away the material, then filled the hole with dirt. They did an excellent job! The time from booking the work to having it completed was about a week. The crew arrived on time, worked quickly and efficiently and cleaned up the site when they were finished. The only sign they'd even been there is that there is no longer a tree! I highly recommend Allen's and would not hesitate to use them again.

We used Allen's to get the sweetgum sprayed in our backyard. We did not have the sweetgum on the right of our house sprayed. If you look at the photos below. It is very obvious as to which one we had done. We defiantly recommend Allen's and will be calling them again soon in hopes to get some grass growing in our backyard.
