Don't Try Installing Your Own Windows Without First Knowing These Expert Tips

If your current windows have broken panels, look worse for wear, or aren't energy-efficient, you might want to replace them. Alas, new ones can cost from $3,441 to $11,840, depending on the number of windows, the frame material you pick, its style, and glass inserts. Labor charges impact the pricing, too, with experts charging between $100 and $300 per unit. Particular styles or materials might have a pro charge about $600, and be prepared to shell out $1,200 to $1,500 for hurricane impact windows. To save a few hundred or even thousands on installation, you might consider learning the basics online and attempting to renovate your windows on your own. However, you should think twice before going this route.

Leo Alabovitz, the founder and CEO of JMI Windows & Doors, tells House Digest in his exclusive interview, "New windows and doors are not rocket science; however, they are an art form that takes years to master. There are plenty of 'do-it-yourself' people out there who have the ability to complete a project like this. However, I find most people think there are a few screws and the job is done." But there's much more to the process, requiring specific tools and products for a successful installation. Moreover, "These items will need to comply with state and local building codes and regulations," our expert explains. Removing existing frames is a complex process as well.

Sharing why window installation is best left to professionals, Leo Alabovitz reveals in his exclusive House Digest interview, "Removing windows and doors can be a task, but before you do, you will need to pull the proper permits for your renovation." But if you hire professionals, you can have them secure the necessary permits. That said, don't assume they'll handle all documentation for you; conduct your due diligence before hiring someone to work on your home.

Additionally, "Utilizing a window and door company is preferable because a team of people are specialized to assist you with each requirement, ordering the proper products, pulling permits, delivery and disposal," mentions our window expert. He adds, "Experienced window and door installers can remove a window in about 10 to 15 minutes and install the new window in the same amount of time. An experienced two-person team can complete an 8 to 12 window install in one day." Since using incorrect techniques can lead to personal injury, fail to meet local code requirements, and may void the frame's warranty, it's better to contract a professional.

If you're still willing to risk it to save a significant sum, Alabovitz warns that things might not always go your way. "Poor installations can not only lead to failing the permit inspection but can weaken the integrity of the structure of your home, allowing dirt, water, insects or unwanted people to enter your home." In certain instances, you might end up paying twice for the materials as well as installation.

If you're a pro DIYer and determined to try installing new windows yourself, Leo Alabovitz shares a list of items you'll require exclusively with House Digest. "You'll need a level, hammer, mallet, crow or breaking bars, a drill, a power saw, a table saw, a miter saw, an oscillator, a utility knife, eye protection, and gloves," adds our expert. However, if your house has stucco or siding, you'll need to grab a few more tools, he advises. Expanding the list, he adds, "... the screws for installation, caulking/sealant, trim, flashing, window tape, siding or stucco to repair areas that may get damaged by the removal." Additionally, ensure you're using the right weatherstripping material in your home.

For everything you need, Alabovitz recommends contacting a window distributor or checking reputable hardware stores like Home Depot or Lowe's. Whichever way you go, "Don't hurry out the door without measuring all the openings you need. Make sure the items you purchase will not only fit but function properly for what is required," he suggests. You also want to think about how you'll transport the tools and products from the store to your home. Either have a vehicle with a flatbed ready (ensure it can fit large window frames) or be prepared to make multiple trips, Alabovitz proposes.
