"This company is first rate. I had used Unicorp several years ago to re-roof our old house, before we moved. They did a great job then, and after we moved 3 years ago to another house, I found out they also did window replacements, so I called on them again. We had them replace several windows at our current home. The work was done on-time, as promised. We are very pleased with the quality and installation of our new windows. The work was done neatly, and on-time as-scheduled."

"I forgot the guy’s name that came to look at the job. He was nice and quick to estimate and explain and not into ‘selling’ services like 2 other companies did. Ordered the slider I wanted and installed it when it came in . I had decided to use a company that specializes in door and window installation instead of the previously used 2 big box garden/supply chains in the area. Very happy with the quality of the slider and the professional installation!"

"Clifton Contracting made the whole process so easy from planning to completion. We are thrilled with the window and the complete change in our basement. We chose a larger Anderson window and an upgraded Rockwell window well. No other estimates could match them."

"Purchasing my new windows was a very pleasant experience from sales to installation. Roland and Tiffany handled the transaction in a very professional manner and I was very impressed that they came by my house during the installation to make sure everything was going well. I am very satisfied with my new windows, they look great. I would strongly recommend Star Improvements for their quality service and competitive pricing."

"A. R. Glass did a fantastic job. Instead of having to replace my windows, they were able to come in and replace the glass for considerable savings. I would definitely have them come again. In fact, I had them come for a second job already."

"I had two old sliding glass doors where the wood around the glass was rotting. The needed to be replaced. I went to the Germantown Home Show and got three companies to come out and do an estimate. Presidential was easily the best choice of the three. The doors got ordered and a month or so later they arrived and were installed the next day. The crew from Presidential was professional and courteous. The door installation went quick and they cleaned up like they weren't even there. I am very pleased with my new doors."

Glaziers FAQs, answered by experts

The best way to transport wine glasses is to pack them upright in a divided, padded box designed specifically for stemware. First, wrap each glass individually with bubble wrap or packing paper, ensuring both the bowl and the delicate stem are cushioned. If you don't have a divided box, you can still pack them safely. After wrapping each glass and securing the material with tape, place them upright in a sturdy box. Layer soft items like dish towels, crumpled paper, or clothing between the glasses to prevent them from touching. Fill any remaining gaps with additional padding to keep the glasses snug and prevent shifting. Finally, clearly label the box as “FRAGILE GLASSWARE” or “FRAGILE–HANDLE WITH CARE” to ensure careful handling.

Whether it's better to repair or replace a broken mirror depends on its size, value, and the extent of the damage. For small, inexpensive mirrors, replacement is often the better choice, as the average repair cost of around $200 can be close to the price of a new one. However, for large mirrors—like those over a bathroom vanity or large floor mirrors—repair is usually more cost-effective. A new large mirror can cost hundreds or even thousands of dollars, while repairs typically range from $50 to $200. You should also consider the mirror's age and sentimental value. Antique mirrors and family heirlooms are often priceless and irreplaceable, making repair the most sensible or only option.

Cutting glass yourself can be dangerous, as the edges are sharp and can easily cause lacerations if you’re not careful. Working with larger pieces of glass is especially dangerous, as they can be cumbersome and difficult to handle without shattering. If you’re uncomfortable doing the work yourself, you can hire a professional to get the job done safely.

Size and weight are the primary considerations when purchasing a bathroom mirror. Properly measure the mirror size that will fit above your vanity. If your vanity sits in front of a drywall without a stud available, you won’t be able to hang anything that is too heavy. Also, check the material and design. For LED mirrors, look up their IP value. The higher the number, the more resistant it is against water and splash damage.

There is no blanket number when it comes to glass thickness for soundproofing. Thicker glass does help reduce noise, but it’s only part of the solution. Most single-pane windows use glass that’s ⅛” to ¼” thick. While increasing the thickness can cut down on sound, the real noise-blocking power comes from stacking layers. Double—and triple-pane windows are far more effective for soundproofing. The combination of mass and separation breaks up sound waves better than thick glass could on its own.
