"I had a broken picture window and had received an estimate from another company that said in addition to the picture window the 2 side windows would also have to be replaced since they were part of 1 unit. In an effort to get a second opinion I was in contact with Angi/Home Advisor who connected me with John of Window MD and I'm very glad they did. John showed up the same day to give his estimate and explained how that even though the 3 windows were part of 1 unit the picture window alone could be replaced and at well less than a third of the cost of the other company. As soon as the new window was ready he put it in and I'm very happy with the work done. The next time I need a window repaired my first call will be to John and would highly recommend him to anyone else needing window repairs."

"We needed to change all (18-20) window screens of our 4-bed room SF home. Rolando did a fine job with these replacements. One of the glass windows accidentally got cracked during manipulation (stuff happens!) but, more importantly, he ensured that the new glass window was the same design and was reasonably priced (we split the cost). The 1st window maker he contracted this work out to delivered a window with the wrong design, so Rolando on his own accord identified another maker and got the correct design made. We appreciate that Rolando persevered until he had the original design in hand. We have no reservations in recommending him for any window/screen work."

Windows FAQs, answered by experts

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.

Installing energy-efficient windows costs between $325 and $2,000, averaging about $400 per window. You’ll have to consider cost factors like the window’s size, frame material, and type. Labor costs in your area will also impact the overall cost of the project, with window installation professionals charging about $40 per hour on average. Different types of energy-efficient windows include:

  • Single-hung: $150–$2,500

  • Casement: $150–$600

  • Double-hung: $250–$3,000

  • Picture: $200–$650

  • Bay: $480–$1,920

On average, hurricane windows last between 20 and 30 years. But some windows only last 10 years, while others can last 50 years or longer. Vinyl hurricane windows have a shorter lifespan than aluminum, so invest in high-quality hurricane windows and properly maintain them to get the most out of your investment.
