"All went fine. First a door to door sales person , and we made an appointment with an estimator. A few days later she called to confirm a couple hours before the app.  She arrived on time and we came to an agreement  on the job and price.  Later someone  showed up and measured all the windows and ordered the custom built windows. About 10 days later they called and made an app. for installation,  the craftsmen arrived on time and did a wonderful job.  Jack J Bradbury

"Counters look good, however, there was a HUGE mess. Tons of old counter top in every one my drawers and in all of the cabinets. Basically no clean up, no attempt to. In addition, they got glue in the window track and the window couldn't open. I called multiple times to have this fixed weeks apart. I did get an apology for them forgetting to come out after the first call. However, a huge mess was made getting the glue off the window seal and not cleaned up even a little bit. Rude...acted like we were inconveniencing them. Never apologized. The counters look great but customer service definitely left a sour taste."

Windows FAQs, answered by experts

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

You can add any type of window to a brick house, so long as the window has proper support. Windows with wider openings and windows in brick walls will need a lintel to support the extra weight above the window frame. A lintel is a support beam that distributes the weight from above evenly around the window.

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

Vinyl windows have a few cons to consider before installing. For instance, while vinyl windows are energy efficient in terms of maintaining your home’s temperature, the actual process of making vinyl windows involves chemicals that are harmful for the environment. Vinyl windows are also less customizable than some other types of windows.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.
