"I must admit, I had Unicorp replace all of the windows in our home with new vinyl energy efficient windows 10 or more years ago. Their installers were excellent. The quality of their windows were excellent. The proof in the pudding is that after 8 years not one of my windows has an air leak. Not one has leaked water. Not one window has had the vinyl or track break. In short, nothing has happened. Now that's a quality window! We also purchased a custom sliding glass door (in the kitchen to the deck) from Unicorp that to this day I believe is the best door in my entire home. That door is opened and closed constantly to let the cats in and out. If you own cats, you will understand how often that door is opened and closed on a daily basis. We have not had a single hiccup ever with that door. And in the winter, I sit right behind the door and no matter how cold or windy it is, I never feel a thing at the kitchen table. Because Unicorp did such a great job in replacing the windows in our home, my wife insisted that we use Unicorp to replace the roof last week. If you see my review on the roof, they did a 5 star job."

"This is the second time that we hired Zen Windows for a project, and we could not be more pleased with the service, professionalism and the results on both occasions. They are very responsive, helped us identify the right products and made the entire process as stress-free as possible. Replacing windows and doors is a big project, and having a company you can trust will do it right makes all the difference. Scott and his team are great to work with!"

"Innovative Home Improvement did an excellent job with the installation of our windows for the entire house. Paul and his team are very trustworthy and honor the commitment to the customer for a quality product, excellent service, and superior responsiveness to you no matter the length of time. Even though our initial window install was 20 years ago, one call to Paul resolved a minor problem the next day. Outstanding!!"

"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."

"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."

"I received several quotes to replace five windows in my home. Whiting Co was significantly less than other companies. I was a little nervous to go with the lowest bidder, but the salesman Ken was reassuring and explained the whole process. There were no heavy sales tactics and everything was straight forward. The installation crew was efficient and did a great job. They left the house clean when they were finished."

"This is the 3rd time I have used this company. As usual we have been very pleased with the quality of the work. Nicole is very responsive when I call her for a service appointment. This time Jonathan came to do the work. I had a bathroom mirror where the screws holding the mirror has gone into the drywall with the anchors. It was very unsteady on the wall so I asked if it needed to be replaced. Jonathan said that he could move the mirror slightly and put the screws and anchors in new holes and at the same time mend the existing holes that are not being used. He did a great job with the mirror and the old holes in the wall. The bottom of the wooden frame on my patio door has rotted over the years and it needed to be replaced. Since I have no idea what to buy to do all the jobs, as before the tech went to my local Home Depot to make the purchases. He came back with water-treated slab of wood for the bottom frame. He said it would take about 2-3 hours for him to take the door out and to make the replacement piece. It sure did take that long and more. I was very impressed with Jonathan, he managed to take a slab of wood, make it into a U-shape frame on the top and make holes on the bottom for the sliding door wheels. Unfortunately, he had a little mishap with the door. When he tried to unscrew the two bolts on each side, one of the bolts would not come out, I guess it was stripped so Jonathan tried to cut the bolt with his saw which he did, but not before he accidentally nicked the double pane tempered glass on the door. The entire outer glass pane has cracked but not shattered into pieces. Jonathan had to order a new double pane tempered glass for my door which would take 7-10 days and then come back to install it. Of course I was not going to be charged for the new glass or for the installation. Jonathan and James came back 2 weeks later and installed the new glass. The bottom frame looked good after Jonathan put a coat of primer on it. I will have to call them back in the Spring to paint the entire door among other paint job that I may have for them by then. The pull down light was installed and a new extension cord was replaced on the workbench light fixture. Good thing I purchase the Angie's List deal online before hand and saved a little bit of money there. Overall, I am still very happy with the job. The price is a bit more than I anticipated because of the work involved in making the wooden piece and of course Jonathan was on the clock too when he went shopping at Home Depot. The entire staff were very professional, friendly and professional which I really appreciated. I have called other handyman company before I settled on this company. The other company wanted me to supply the material. What the heck do I know of what to buy so that is why I did not use them. It is more expensive for them to go and get the stuff they need but worth the hassle and time of me getting the wrong stuff and had to take them back and maybe still get the wrong stuff again, so better for the tech to go."

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.

They offer increased safety, noise reduction, and protection from extreme weather.

Hard water stains can permanently damage your glass if left untreated. The minerals dissolved in the water can etch the glass, causing long-term damage and affecting the overall integrity of the surface. Luckily, it is pretty simple to remove hard water stains by using vinegar, baking soda, or commercial cleaners.

The size of your mirror depends on the size of your vanity and personal preference. Most people prefer a mirror that is 1 to 2 inches narrower than the width of their vanity, while others like a mirror that’s the same width as their vanity. Remember that the mirror should sit 5 to 10 inches above your faucet when choosing dimensions.

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.
