"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

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

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.

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

Most installations take 1-3 days, depending on the number of blocks and customization requirements.

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line.
