About Us

The LEW Team


Much has changed since 1969, when Leon E. Wintermyer began his excavation business with a single bulldozer.  Our company has experienced tremendous growth and has established solid relationships with numerous developers, contractors, and design professionals throughout Pennsylvania and Maryland.  Our signature of quality is written across the landscape where we’ve completed hundreds of site work projects – totaling thousands of acres and millions of cubic yards of earth moved and shaped with precision.  We are proud of our heritage of building communities and industrial & commercial sites, where people work, shop, and enjoy life – and we are pleased to continue this 47 year legacy.


Estimating & Pre-Construction


The LEW Estimating Team is a group of seasoned construction professionals that bring a wealth of field expertize to the pre-construction process.  Our senior estimators have worked in the field and experienced the elements – mud, heat, and cold and understand what it takes to achieve production and meet the schedule in various geologic/soil conditions and terrains.


As the LEW estimators study drawings and build the estimate, they visualize cutting and filling a vast site to grade & installing storm water and underground utilities at various depths.  They fully understand how to sequence & build a project with the appropriate equipment, crews, subcontractors, and materials, and how to transform the scope of work in to competitive cost estimate.


The result is a well thought-out proposal that gives our customers the confidence of having a qualified number when putting together a general construction proposal or obtaining project financing.


Project Management & Construction


The LEW Project Management & Field Supervision Team knows “the business” of building a project:

  1. Safety
  2. Quality Workmanship
  3. Meeting the Schedule
  4. Meeting the Budget


When all four of these elements are held to a high standard, they form a successful project.  Our team understands it is our duty and responsibility to protect all four of these important elements for our customers.  We’re not only in the business of construction – we’re in the business of caring for our clients and keeping them in business.


Unexpected issues that arise due to unforeseen existing conditions and changing weather must be effectively managed.  We realize it takes constant communication and teamwork to develop solutions, in order to achieve ongoing success.


At LEW we have a high regard for the foreman and crews of expert, heavy equipment operators & skilled laborers.  They are the ones that make it happen.  We believe our focus on their success turns in to LEW’s success.  Our high regard for field teams are matched by their dedication and accountability to carry out a high degree of safety, quality workmanship, and productivity.




Trusted relationships and repeat business are built on successful projects.  We’re striving for general contractors and real estate developers who want LEW on their projects because they can count on positive results.

“We had a working relationship with LEW for over 35 years and have had all of our jobs successfully completed on time and within budgets. Within the last two years, they have completed three Giant Shopping Center sites for us that included significant demolition, all phases of site and utility work, along with Penn DOT right away work and red light installation. This work has totaled approximately $30 million. I can without reservation recommend LEW for multifaceted site work from single family subdivision to large retail and industrial projects.”
