"The installers came on time and were totally professional, experienced and worked continuously until the job was done. The triple pane windows are fabulous because compared to our old two pane faulty windows, not only are they solid and beautiful with no wind blowing through, but also the nearby road noise is greatly reduced. We needed to use plastic film to insulate the old windows and when the wind blew the plastic would billow like sails! The new windows make our condo seem like a true home."

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."

Windows questions, answered by experts

Whether you need a permit to install a bay window depends on the project's scope. Replacing an existing bay window typically does not require a permit. However, if you are adding a new bay window, requirements can vary. Adding a new bay window to the front of your house usually requires a building permit, while adding one to the side or back of your house often does not. It's always best to check with your local municipality to confirm the specific requirements in your area. Additionally, if you live in a historic district, you should consult your neighborhood association to ensure your project complies with their construction guidelines. If you're unsure about the process, a professional can provide guidance.

While all windows require some maintenance, vinyl windows are the least hands-off. They’re easy to clean, weather resistant, and extremely durable. If you like the look of wood windows but hate the price tag and high maintenance requirements, you can add a faux wood finish to vinyl as well. 

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

You will need about half of a caulking cartridge to caulk one window. The average home has eight to 10 windows, so you would need about 4 or 5 cartridges to caulk every window in an average-sized house. However, you may not need to caulk all the windows at once. If just one window has a pesky draft, you may only need half of a cartridge to fill in the gaps.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.
