If your existing windows appear drab and lifeless, you might consider replacements. However, installing windows in a house should be done by an experienced professional rather than through the ever-popular do-it-yourself (DIY) method. Why? Among other reasons, a qualified window installer possesses the knowledge and tools to complete the job correctly the first time. At Moss Roofing, we expertly install windows for residential homes throughout Indianapolis.
The Cost Of Do-It-Yourself (DIY) Installation Of Residential Windows
Many homeowners opt for the DIY approach to home improvement or remodeling projects. However, consider the following challenges associated with taking a DIY approach when installing new windows in a house:
DIY Window Installations Incur A Greater Probability Of Failure
Almost a quarter of homeowners’ do-it-yourself (DIY) window installations fail, necessitating professional intervention. Instead of becoming just another statistic, opt for a qualified window installation specialist to remove your old windows and install new ones correctly. A skilled professional possesses the knowledge, experience, tools, and equipment to do the job correctly.
DIY Window Installations Experience A Higher Percentage Of Leaks
Nearly one in five DIY window projects face air or water leaks within the first year, resulting in costly exterior and interior damage to a home. Often, the newly installed windows will require replacement. This issue is avoidable if the homeowner hires an experienced window professional to properly install and seal the new windows. A specialist will understand the correct sealing techniques.
DIY Window Installations Average A Lower Rate Of Energy Efficiency
Every window manufacturer provides an energy efficiency rating that measures energy loss through the window. Energy efficiency pertains to a window’s insulation (U-factor), solar heat gain from the sun (SHGC), natural light transmission (VT), and air leakage. Professional installation typically achieves 95% to 98% of the stated energy efficiency rating, while DIY installation usually averages only 82%.
DIY Window Installations Provide A Lower Return On Investment (ROI)
Investing in new windows can be beneficial. Professionally installed windows offer a return of 72% on the investment at resale. In other words, if a homeowner spends $10,000 on new windows, they can expect to recover $7,200 upon sale within a few years. In contrast, DIY installations generally yield a return of only 60% on the investment, often due to potential issues flagged during a home inspection.

Installing Windows In A House: Why Hire A Pro Instead Of DIY
Experienced window installers work in many types of homes, gaining deep insights into the unique challenges of different window installation projects. Consider the following advantages of retaining a qualified professional to install new windows in a home:
A Professional Window Installation Ensures The Right Window Selection
Big box retailers typically offer standard, off-the-shelf window solutions. However, a reputable window installer will likely have a wider selection for homeowners. Hiring a professional goes beyond basic service—they provide expert insights by carefully assessing your home. Their deep knowledge allows them to suggest solutions you might not discover through a do-it-yourself method. You’ll benefit from specialized recommendations tailored to your specific situation.
A Professional Window Installation Requires Less Time To Complete
Save time. A professional window installation crew can install 10 to 15 residential windows per day. They will work efficiently to complete the project on time. In contrast, a DIYer typically needs 4 to 8 hours per window to do the job correctly. Hiring a professional could save five to ten times the amount of time it takes to install your windows.

A Professional Window Installation Minimizes Unexpected Cost Overruns
Today, a professional window installation typically ranges from $300 to $1,200 per window, including materials and labor. In contrast, DIY window installation can cost between $200 and $800 per window. However, this DIY expense does not cover the cost of acquiring the tools to complete the job correctly. Average DIY projects tend to exceed the original budget by 27% due to unanticipated complications.
A Professional Window Installation Protects The Manufacturer’s Warranty
86% of manufacturers’ warranties require professional installation to guarantee coverage remains in full force. The typical warranty on professional labor spans 5 to 10 years. Safeguards against material defects can last for the window’s lifetime. Homeowners need to know that a DIY installation could void the warranty. It could also cost the homeowner significant amounts if the window becomes irreparably damaged.
