"We called Machen for an estimate to tear off our old roof on our house and detached garage. They were very responsive and Jodi even came out on a Saturday to give us an estimate. He was very knowledgeable regarding the materials and products we needed, and we were impressed that he actually climbed the roof to take all of the measurements, where other contractors we had contacted did not. The estimate we received was fair considering that the roof deck would need wrapped and the amount of ice guard we needed. Jodi and his team were on time every day and got right to work. They took their time on the job and were very conscientious about the work performed to ensure it was done correctly. Jodi takes a lot of pride in ensuring the job site remains neat and takes a lot of care to ensure they thoroughly clean up before leaving for the day. We ran into heavy rain halfway through the project and Jodi even came out on the weekend to ensure that the roof was water tight before the rain hit. The new roof looks great and we are very pleased with the end result!"

Glass Block questions, answered by experts

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.

Yes, many professionals provide custom-cut glass replacements for enclosures that require precise sizing.

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

Although glass block windows are made of multiple layers of thick glass, they can still break. If an individual block shatters, it can be removed and replaced, but this is a job for a window repair professional. The project is often complex and may require breaking the block further for removal. Do not attempt to handle it yourself, as the broken glass can be dangerously sharp. A professional will have the necessary tools and expertise to replace the broken glass block quickly and safely. Before hiring, confirm that the repair pro has experience with this specific type of window.
