Trees are essential to our landscapes and the environment. These magnificent entities provide us with clean air, shade, a habitat for wildlife, and enhance the natural beauty of outdoor spaces. With that said, ensuring trees remain healthy and sturdy goes a long way in preventing hazardous situations down the line. That’s where Sesmas Tree Service comes in as your go-to tree company for comprehensive care and maintenance. Our certified arborists leverage extensive expertise to inspect, detect, diagnose, and address warning signs before they worsen. Here are common indicators that can help you spot a dangerous tree.

The Most Overlooked Signs of a Dangerous Tree

Leaning or Tilting

One of the most overlooked signs of a potentially hazardous tree is sudden leaning or tilting. If you notice a tree in your yard leaning precariously after a storm or heavy rains, call a professional tree service provider quickly. This is particularly true if the tree is leaning toward structures, utility lines, or hardscaping features. Leaning often suggests a weakened root system or structural issues that need immediate attention. A professional tree company has trained and certified arborists ready to assess the extent of the damage and determine whether replanting or a complete tree removal is necessary.

Cracks and Cavities

Trees are sturdy and durable with the proper care. However, visible cracks, splits, or cavities in the trunk suggest a more severe underlying problem. These can be signs of structural deterioration or internal decay, which require quick intervention to prevent breakage or even a full collapse. Besides horizontal crevices in the trunk, pay close attention to areas where large branches join the trunk, as these junctions are often more vulnerable. By having a tree company inspect and diagnose the problem, you can rest assured that your trees are in top shape all year long.

Dead or Hanging Branches

Dead or precariously hanging limbs pose serious safety risks if left unattended. While they may not raise concerns initially, these branches can break off and fall when you least expect them, causing serious injuries and devastating damage. Additionally, dying or dead limbs can attract unwanted pests and cause diseases to spread throughout your yard. You can avoid such scenarios by hiring a professional tree service for routine trimming and pruning, ensuring potentially dangerous branches do not wreak havoc.

Fungal Growth

Fungi are common around the base of the tree or on the trunk, especially in areas with a wet climate. However, sometimes fungus growth is a sign of internal decay, prompting professional intervention before the damage gets out of hand. Mushrooms, conks, or other fungal structures are clear indicators of a compromised tree. Over time, fungi can weaken the wood and contribute to instability, leading to premature tree removal. It is essential to regularly check for signs of fungi growth, especially after wet weather, ensuring moisture does not accelerate growth.

Root Problems

Roots are not always visible, which makes it challenging to detect signs of deterioration without expertise and experience. If the ground around your trees is cracking or lifting, it may suggest a compromised root system. This is usually accompanied by fungal growth at the base in the case of decay. If you suspect a tree in your yard has weakened roots, whether it is due to infestation, infection, or severe weather conditions, call a tree company quickly to resolve the problem.

Regular inspections by a tree service provider go a long way to ensure the safety of your property and those around you. With this in mind, working with the experts from Sesmas Tree Service can ensure you address the root cause and prevent hazardous scenarios down the line. Contact us today to book an appointment with our experts and take appropriate action to keep your yard safe and lush year-round.

Customer Reviews

3 large Leyland Cypress trees removed near front of our home. Excellent service, professional crew, very competitive pricing for superior work! Rolando provided the initial estimate and the  follow up and was the best in terms of customer relations. I'd both use this company again AND highly recommend them.

Susan Hitchcock

This is the 2nd time we have used Sesmas Tree Service. They are a wonderful company to deal with. They were on time, professional, and very thorough. They cleaned up prior to leaving and went out of their way to protect our plants and landscaping. And they kept to their proposal with no hidden cost or add ons. Definitely a five star experience!

Gene McFadden

Wow!  I deal with tree services in my professional work and I can honestly say Sesmas is by far the most professional, best equipped, efficient, safety conscious, and communicative service I've ever encountered.  Their price was very reasonable and they even went so far as to include additional work without increasing the price.  Call them!  Now! They are very quick to respond.

Scott McLendon

We've used Sesmas several times and have always received excellent service.  Estimates are quick and easy and the crew is efficient and leaves the property clean of debris.  Recently we needed a tree removed next to a heavily landscaped area.  Sebastian went over everything with me in detail and listened to my concerns.  The crew did an excellent job in removing the tree with minimal disturbance to the surrounding area.  We are pleased and will consider them again in the future for pruning and tree removal.

Tonia Griswold

Sesmas Tree Service was amazing! I had two dead trees cut and a lot of trees that were already down on my property removed. Sebastian came out and sent the quote in writing within 24 hours. We were in the process of scheduling the service when a slot opened up sooner snd I was able to go ahead and get the work done. Everything was explained ahead of time for what to expect. The crew was very efficient and professional.  All of the work and cleanup was done in one day. I would recommend Sesmas for your tree cutting/cleanup needs.

LaDora Woods

I hired Sesmas to cut down a very tricky tree that was hanging over my house as well as a few large limbs. They did a great job and had the machinery to get the job done right.

Perry Hartman

Great experience with Sesmas. They were meticulous with my tree removal, safe and efficient. David’s communication throughout the process was much appreciated. Highly recommend!

Lindsay Ellenburg

Great experience with Sesmas Tree Service. The arborist who came out was a Board Certified Master Arborist, and you could immediately tell he knew his stuff. He took the time to explain what needed to be done, gave us clear options, and helped us feel confident from start to finish. The whole process was easy and professional. We’ll definitely use them again.
