I had an urgent project to replace a patio door and a front window during several weeks of raining. Leszek responded quickly and gave me a very reasonable quote. The work was completed on time, communication was smooth, and the installation looks great. I really appreciate the professionalism and would definitely recommend him.
I had Lema Windows pull out a window to replace it with a door. The door is great quality. The price was very reasonable and the work done exceptionally well in one day. Communication throughout the process was very good and no surprises anywhere. Will definitely have them come back when I change out my slider.
We had Lema replace our basement door. They were absolutely awesome! Very friendly, fast, communicative, and professional. And as a woman, I felt completely comfortable with everyone who came out to the house (Leszek to give an estimate and his two team members to do the installation). I feel so grateful for this experience and we will definitely call them again for our front door replacement.
We first had this company replace the windows on our second floor to test the quality, and the difference was amazing - the rooms stayed warmer in winter and cooler in summer thanks to the better insulation. After nearly a year of enjoying the results, we hired them again to replace all the windows and doors on the first floor. The team is professional, friendly, and does excellent work. Highly recommend!
Super reliable, great price, clean work, and great craftsmanship. I'd originally gone to a well-known lumber yard for a quote, then another, and yet another. I would rather support small businesses than big box stores. While on vacation I decide to email Leszek the owner and forwarded him the quotes. Took my chance with Lema Windows. He was able to beat the price and put in the orders for me, it was full of house windows and doors. 15 windows or so. 3 months later all materials arrived. Came out and installed everything within 2 days, and kept the interior clean of dust, and exterior debris removed. Stucco's job matched super well. The interior trim was left out by me as I'm doing the custom trimming. Def recommend and refer out and will come back again for the entrance door.
