"This is my second window job with MHP. First time, we upgraded a dozen windows in our home with a high-end product. Everything went perfectly. When I needed replacements in my rental I was looking for value. MHP beat the price of 2 other bids with a better product. Paul and Cathy are true professionals from the first contact to job completion."

"We have had other window, cleaners over the years, and recently have had other quotes. Boyd window cleaners beat them all. They returned calls promptly, were on time, and did an exceptional job. They were clean and not messy and left our windows, spotless. We highly recommend them."

"Fantastic. Everyone from start to finish was super professional and super friendly. The sales/estimate and measurement guys both did a great job explaining things to us, the windows look great and fit perfectly (already got compliments on them), and the guys installing the windows were all very respectful about keeping from making a big mess. Everyone we dealt with had great attitudes; they worked hard but were so friendly it felt like they were just friends helping out. Great service overall, much better than another place we checked out earlier, and the price was actually much more reasonable, too."

"Window Wizards did an excellent job. They pressure washed my driveway, walkway, back patio, and also washed and cleaned my patio doors. Window Wizards was very professional and did a thorough job and I would definitely hire them again and refer them to others."

Windows FAQs, answered by experts

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Not every home needs window capping. Whether or not you need to cap your windows depends on your climate and window frame materials. Wooden windows should have window capping if moisture is a problem. Arid climates like the Southwest may not need window capping due to low rainfall and low humidity.

Arched windows are slightly more expensive than standard rectangular ones, but they only cost $50 to $100 more per window. However, adapting a rectangular wall opening to accept an arched window can add $200 to $400 to your total, making them a more expensive option over sticking with a standard window replacement.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

When your double-hung window upper sash keeps falling down, it means you could be letting out warm air in the winter or cool air from the AC in the summer. That means your HVAC system works harder to warm or cool the house, costing you extra on electric bills.

If the lower sash continues to fall down, it means when you’ve popped open the window for fresh air, it could slam shut. In addition to being inconvenient, this could be dangerous if you have small kids, children, or pets that like to hang out by the window.
