We decided on Primary Seal Windows & Doors because of the triple pane glass, foam insulation and reinforcements in the frames. We learned that the lifetime warranty is a huge importance. Having all the information we needed, we placed the order. We decided on the triple pane over double pane glass because we felt the cost of heating oil was only going to go up in the future and changing the windows again was out of the question. The windows were installed in April and we are very happy with the work done. The installation crew was neat and professional making sure they addressed our concerns. The job was completed in one day and the work was fantastic. All the windows were capped beautifully and the caulking was perfect. Now that three months had passed since they were installed we can feel a dramatic difference in the rooms. The drafts are gone and our heating bills will drop significantly compared to last year. One other thing that occurred that no one mentioned to us is how much noise these triple pane windows block out. We are extremely happy with our choice. Our new windows are beautiful and the envy of all our friends and family. We would definitely recommend Primary Seal Windows & Doors to others.
