Ventanas a medida en Sheffield, IL

“We've worked with Illinois Valley Glass & Mirror for over 20 years. We appreciate their product knowledge and professionalism on our clients' projects. They are a good source of all sorts of glass work, including shower doors.”

“We purchased all new Marvin windows and a sliding glass door for our home from Seiffert Lumber. We worked with Jeremy Devol. Jeremy did an outstanding job from start to finish. A subcontractor, Ehrecke construction was used to install the windows and they also did an amazing job. Their quality craftsmanship, attention to detail, and consideration were appreciated. They treated our home as if it were their own. Jeremy oversaw the project and ensured everything was done in a timely manner and to our satisfaction. We absolutely love our Marvin windows. The quality of the windows is far and above all the other windows we looked at. If you are in the market for new windows I would highly recommend Seiffert Lumber.”
