Our Mission

We provide our customers with Total Building Comfort that only comes from having superior and reliable Electrical, Mechanical, Plumbing, Facility Servicing and Maintenance contracting services L.H Cranston offers. Servicing the Baltimore Washington area for over 60 years, we have earned the right to long-term relationships with our customers; built on our commitment to working with them from the design phase through the build and maintenance phases.  We believe in Unparalleled Customer Service and a positive experience in every engagement. 

Community Presence

Established in 1946, locally owned L.H. Cranston is unique. We combine our powerful resources in our mechanical, electrical, plumbing and service divisions with our highly skilled professional craftsmen. This allows us to provide our customers with a full continuum of service contracting for even the most complex building projects. While other contractors may offer only one specialty, L.H. Cranston can be a single-source for all electrical, mechanical, plumbing and service contracting needs.  In this way, L.H. Cranston can streamline a project while offering single-source responsibility and accountability. 

Commitment and Persistence

At L.H. Cranston we believe successful projects are delivered on time and on budget and exceed our customer’s expectations. Listening to our customers, understanding their needs and doing what we say we are going to do has enabled L.H. Cranston to become an integral part of the Greater Baltimore and Washington DC communities. Our reputation for superior service and reliable results are reasons why we have been selected to participate in the Design, Construction and Servicing of many of the building projects throughout the region. Where feasible, we participate in the design phase of the project providing valuable cost effective recommendations addressing current and future needs.
