Why Keystone Stands Out in Tree Care

Bob McMullin, a Penn State-trained forester, started Keystone Tree Experts as a one-truck operation more than 50 years ago and has grown it into one of the most trusted names in Bucks County tree care. Our certified arborists combine advanced training with a preservation-first approach, offering clients solutions that prioritize health and longevity.

Education remains a cornerstone of our work. Weekly training sessions, staff development, and community forums ensure our recommendations are always informed by the latest science. This ongoing investment in knowledge is why our clients continue to rely on Keystone year after year.

 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.

 Trustindex verifies that the original source of the review is Google. If you need a reliable tree service call Keystone!  They are fast, efficient, and a pleasure to deal with.  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.

 Trustindex verifies that the original source of the review is Google. For starters, Keystone always gets back to me when I call.  Their technicians are the best and offer advise when asked and offer suggestions as to what may be  needed to maintain your trees. 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.

Quakertown Tree & Shrub Care Services We Offer

Our certified arborists provide customized tree and shrub services that address immediate issues and long-term health of your plants.

Plant Health Care Programs

Routine monitoring and proactive treatments form the backbone of our Plant Health Care programs. By focusing on early detection, we help reduce risks from pests, disease, and stress before they become major problems.

Insect & Disease Control

From emerald ash borer to fungal infections, damaging pests and diseases can spread quickly. Our arborists identify the exact threat and apply targeted insect and disease control treatments at the right stage, preserving tree health and stability.

Fertilizing

Deep root fertilization delivers nutrients directly into the soil where roots can absorb them most effectively. This fertilizing process improves growth, increases resilience against drought and pests, and supports overall vitality.

Small Tree Pruning

Pruning helps trees develop proper structure and reduces the likelihood of hazards. Our arborists carefully remove interfering or weak branches, shaping trees for safety, appearance, and long-term strength.

Consulting

Our consulting services give property owners access to expert guidance on planting, construction planning, and large-scale maintenance. Municipal clients also turn to Keystone for arborist consulting, reflecting our role as a trusted regional authority.
