"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

"The tile in the shower was done well, but the tile on the floor was not. The tile was uneven, grout missing and they put in the wrong drain cover. So, they came back and fixed it. The etched window in the shower that was caulked had mold growing under it. They came back and re-caulked it. The thermostat for the floor was not installed on it's own dedicated circuit, so an electrician has to come and fixed it."

Windows FAQs, answered by experts

Bay windows are supported by braces and industrial strength cables, often at the top of the window but sometimes at the bottom. The bay window may need buttress supports if installed on the second floor. Wood screws on the interior also hold the bay window in place. Bay windows are heavy and need proper support to prevent sagging and wall damage. You need to ensure that the support system can hold the weight of the window and the roof cab over the window.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

Steel windows are durable and last a long time, but not in all weather conditions. If you live near the ocean, these windows might not be the best choice, as the saltwater breeze can corrode the metal. Steel windows are also more expensive than other types of windows. However, with that high price point comes a sleek, distinctive design that many homeowners find appealing, especially for modern decor. You can also restore steel windows to get a longer lifespan from them, so they can last longer than vinyl, aluminum, and even wood.

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

Mulled windows are no less efficient than individual windows, provided the wall opening is the same size. Larger wall openings filled with glass will always reduce overall energy efficiency, as glass transmits heat more readily than a solid wall. If the windows that are mulled together have the same square footage as individual windows, you might actually see a small decrease in your electric bills, as mulled windows let in more natural light that can reduce interior lighting costs.
