" When I decided to purchase new siding for my house, I called only one business for an estimate.  I chose Thermal Tech due to past services I received from them.  A few years ago, Thermal Tech installed three picture windows and seven vertical slider windows on my house.  I discussed siding with Jay Nordwall at that time.  He was honest, informative and patient with my questions.  I contracted Thermal Tech for three garage windows, a back exterior door, soffit and siding.  The installation of my siding was flawless.  I am ecstatic over the final look of my house.  I urge anyone considering exterior upgrades to their home to contact Thermal Tech and relax into the confidence of an excellent job performed with professionalism.
