In business since 2007, MT Weatherization has a long history in building science and understanding the building envelope.  With approximately 30,000 audits under our belt, we are proud to boast a savings of almost 80 million KWH.  That’s a savings of approximately 21.5% a year!  These savings compound year after year resulting in a return on your weatherization investment. 

We are both serious and excited about what we do.  We take great pride in promoting a message of sustainability to those we serve.  The products we install, such as spray foam insulation and silicone roofing, are exceptional cutting-edge technologies that not only meet the customer’s basic need for insulation and a roof, but also provide benefits above and beyond those basic needs.


MTWX is a local full-service weatherization contractor serving the greater Harrisburg and Johnstown areas. Our mission is simple: to save energy through weatherization and insulation solutions. We offer home energy audits to pinpoint where and how your home can better retain energy.


Backed by our sister companies, MT Heating & Cooling, MT Spouting, and MT Insulation, we reduce energy consumption in building structures by improving their energy efficiencies. Our building scientists are certified by the Building Performance Institute (BPI) and conduct expert analyses of structures and diagnose prescriptive measures which will allow buildings to run more efficiently. Our professional installation crews implement and install energy saving measures, such as air sealing and improved insulation. Our work is guaranteed to improve energy efficiency and air quality in any structure we weatherize.


With the use of cutting-edge technologies and materials, we strive to reduce energy consumption in the Mid-Atlantic Region, alleviating strain on local power production facilities, conserving natural resources and providing improved thermal comfort and air quality to our customers’ homes and offices.

Let's get you on the schedule!
