Installation was flawless. Windows look like they are part of the house both inside and out. Never knew the right window could make such a difference. Our south facing recreation room with its older picture window used to heat up intensely. The replacement window reflects that heat back outside and the result is phenomenal !

We were referred to Lombardozzi Construction through Home Advisor for our sliding glass door replacement. Our sales guy, Ben, was super knowledgeable and gave us some great advice to help us with our search. No pressure at any time, just clear expertise. Andy, Tony, and Hannah were all great through the process from measurement to installation. They are very thorough and I can't say enough about the quality of the product and the craftsmanship. We had a great experience working with them from start to finish and I highly recommend this team.

STL replaced 21 double hung windows, as well as two entry doors in our home. The entire process was handled very professionally, with great communication and results. The sales person, Dan, was very helpful in explaining the many available options, and also helped us work with the insurance company. Andy and his crew worked quickly and efficiently to get the work done, were able to work through a couple of unexpected problems, and kept a clean jobsite. Overall, a great experience!

Why New Windows and Doors Benefit Clayton Homeowners
According to Point2Homes, the median construction year for homes in Clayton is 1954, and over 45 percent of the housing stock dates to before 1950. Many residences still have original windows and doors that are well past their useful life.
Neighborhoods like Claverach Park and DeMun feature Tudor, Colonial Revival, and Arts and Crafts homes with large window openings and prominent entry doors. These homes deserve replacement products that respect their character while delivering modern efficiency.
Home values here average around $887,159 according to Zillow, among the highest in St. Louis County. Protecting that investment starts with the most visible parts of the exterior. New windows and a well-fitted front door sharpen curb appeal, reduce energy waste, and show prospective buyers the home has been thoughtfully maintained.
The mature tree canopies that make these streets so appealing also create consistent shade and moisture exposure around window frames and door trim.
