 Trustindex verifies that the original source of the review is Google. We have been very happy with the work that Keystone Arborist has done for us.  They have removed very large trees and a very large stump for us..  They clean up beautifully and place mats in our yard to use for their equipment and protect our grass.  We will certainly use them again for any tree service we need done.

They have saved several of my large oak trees from the leaf scorch that has been plaguing the oaks.  Also sprayed and saved a number of my evergreens.

 Trustindex verifies that the original source of the review is Google. Joe comes out every year to inspect the trees on my 2 acre property.  Joe recommended a treatment for one of my Ash trees several years ago, and it has saved the tree!  I think these guys are fantastic, and I highly recommend them if you want to keep your trees healthy.  My motto is tree treatment is a lot less expensive than tree removal, so I try to treat and keep them healthy with Keystone Tree Expert's help.

I have used Keystone for 12 years and have never had a complaint about their service.  They are punctual, courteous and the best in the field.

 Trustindex verifies that the original source of the review is Google. I have been taking care of my property for 30 years.  My house is 2 yards from a very busy road so my trees and shrubs are critical to both privacy and safety.  My friends tease me that I have a garden with a house on it.  I have seen my share of arborists come and go.  After feeling bamboozled more than once, this time I conducted a thorough search and interview process, comparing assessments and pricing of about 5 companies.  Keystone did not try to sell me services I did not need, they showed me issues the others missed and their pricing was the best.  They have been no nonsense and are showing me, not telling me, that they are truly experts.

The certified arborists at Keystone Tree Experts provide customized tree and shrub care services in Langhorne that strengthens plant health while preserving the natural beauty of local landscapes.

Plant Health Care Programs

A Plant Health Care (PHC) program is the foundation of a thriving landscape. In Langhorne, our arborists monitor your trees and shrubs year-round, identifying signs of stress, pests, or disease before they cause serious decline.

Insect & Disease Control

Langhorne’s trees face challenges from borers, bagworms, and leaf-feeding insects, as well as fungal diseases that spread quickly in moist environments. Our insect and disease control programs target these issues early using precise timing and environmentally responsible methods.

Fertilizing

Our fertilizing service uses deep root injections to deliver nutrients where they’re most effective, below the turf and directly into the root zone. This process supports robust root development, enhances drought tolerance, and improves the overall vitality of trees and shrubs throughout your property.
