STL Windows and Doors installed all new ProVia Doors and Windows in my recently purchased home. These Amish built products are amazing quality and show the high standards of the company. The quality of the installation was AWESOME! The attention to detail, professionalism, and speed with which the work was completed was the best I have ever experienced with any contractor! I would recommend them to work in any of my friend or family's homes

From start to finish, they were extremely professional and I truly felt they had my best interest at heart. They were time efficient and I felt confident that they would not leave until the job was done to their highest expectation. They have earned a loyal customer and will be going back to them in the future.

Andy is very knowledgeable about doors and did a great job adjusting my door. He is very personable and professional. I would not hesitate to use Lombardozzi for any future door and window needs.

Fantastic job on my Windows!
Love these guys and gals! fixed my Windows and gave me good advise on older Windows! they're good and I love em!
very professional and thorough.
We first chose Lombardozzi Construction to replace the windows and patio doors at our house based on a referral by our son-in-law who was very familiar with their work. Lombardozzi guided us in picking the correct product and was very meticulous with the installation. They went above and beyond to make sure the fit was correct and did the little tweaks on the trim to make sure the finished job looked better than the original. The whole team was friendly and considerate of our property from the time they started to the clean up they did when completed. Last year we decided to replace our front entry door. Again, we were steered to a quality product and the installation went very well.

Pricing is competitive. However, we are still blown away by the talent level! It was not just the finished product that was beautiful but the job site etiquette was on point.. Tony and Hannah did a fantastic job installing our new windows and doors. From contract to completion, everything was professionally handled!

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.

They turned my screened in porch to a three seasons room. They did a great job and I love it. The workmanship and the windows are wonderful. Great quality. The workers are friendly and great craftsmen.
Phenomenal family owned business! Could not recommend them enough!
I'm SOOO excited!! Lombardozzi Const installed my new front door today and it's just BEAUTIFUL! Tony was the man that installed it and his attention to detail was simply AMAZING!! He even coded my key for me! Haha! After he was all done, he took all the trash and vacumed up every spec! He's awesome! I first talked to Matt and was very impressed....I have also talked to Andy and both were so kind and answered all my phone questions. Ben is their salesman and he made all this possible! God bless all of you!! This is a family company that really cares about you and their quality of work. That's hard to find in this day. An Amish community in PA built my door and it's beautiful and solid. They have a LOT of options but I wanted a plain door with no windows...I am THRILLED with my new door! Tony even made sure all the trim corners matched perfectly...this door was installed better than I could ever have imagined. I am so very happy with Lombardozzi Const 💖 Thank you and may God bless all of you!!
Installed a wall and their work made it look like the wall has always been there. Efficient, quality work and even cleaned up after they finished! Would use this great group of people for all our projects!
The folks at Lombardozzi construction have completed several projects at my business. They built our company locker room, 2-storage rooms and a secured project room. Professional, honest, reliable with quality workmanship. Valves that are hard to come by in this day
They replaced the old glass sliding door’s with new ones and they look great! Thanks �
Lombardozzi construction have done several home projects for us. They are very professional but friendly & make your experience with them a quality one. If it's quality you want, they will make sure that is what you receive! I highly recommend them, very knowledgeable & a great group of people 👍🏼
Lombardozzi Construction installed a front door and storm door. Professional, friendly and reliable service. We get compliments on our door constantly. I grew up with a family run business and felt comfortable with them in my home. I will be calling them when we are ready to replace our windows.
Andy, Tony and Hannah are awesome. They aim to please and are very efficient. Give 'em a call.
Lombardozzi Construction has done several projects on our home. Have been very pleased with results. Always prompt.
