"the coming out and inspection of area was great and they sent the original quote in an agreeable, if not a little slow, time. however they missed one item of estimate which they corrected. however, when I requested they split the two room I was told they would but they never came at the agreed time. i called several times as i needed for the insurance, the price seemed reasonable and i was going to use, the person denied he agreed to re-quote each room on its own and told me unless i paid i was not receiving any quote. i am actually relieved, u think i dodged a horrible situation. i cannot recommend however it would not be fair to advise against using the company, as i think the paperwork and not the repair work is what they are lacking."

"SL Contractors was one of the companies who we contacted when we bought a house and decided to remodel the kitchen (which was as old as the house, about 100 years old). We chose Willis because he was full of good ideas and suggestions, and we felt very confident hiring him and his team. The renovation took a bit longer than we expected, but we didn't want to rush seeing how professionally and diligently the job was done. Now we have a beautiful kitchen, a new gorgeous fireplace (that changed the look of our living room), a laundry on the second floor, and a freshly painted house. It looks like new now. Willis also helped us with many smaller things and we are very grateful for that! We will definitely contact him again if we plan another big project."

"Tom was very personable and nice to speak with both when he visited our home as well as our meeting in the showroom. However as this was not our only estimate it was apparent that the quality of cabinets and materials as well as the ability of the installers was limited compared to other companies we had spoken with. Some examples would be that the items in the showroom seemed outdated compared to other products and materials we had seen and actually a lot like what we were trying to replace. When we spoke about our ceiling which continues into a family room and how to update the kitchen lighting without having to repaint and replace the entire family room ceiling the suggestion was to nail trim to the ceiling and thus create a break in a floor plan that is supposed to be one large room. When we asked about under cabinet lighting the suggestion was that since that involved a lot of electrical work that we could purchase stick up lights at Lowes afterwards. This seemed crazy given the cost of new cabinets. While their quote was the least cost of others it also was clear that it was not going to be a kitchen we would be happy with. For those who are extremely budget minded I think this would be a good option but otherwise if you want anything even remotely higher end this is not the place.

Glass Block FAQs, answered by experts

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

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.

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.

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

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.
