Leave a Review for KLM Contractors

We hired KLM Contractors this spring to replace our old vinyl siding with Hardie Plank, install new OKNA windows and Provia front door, and build our portico. The result is an absolutely stunning transformation of our home, which was executed flawlessly by the team. From the moment we met Maciej, we knew that KLM was the company that we wanted to work with and could trust on a project of such magnitude. Maciej walked us through every detail, and added his experience and ideas into our vision to... Read more

KLM recently completed a project of replacing all our windows, two doors, and the old vinyl siding on our house in Jamison, PA. The results are beautiful.

We love the new look of our refinished house and highly recommend KLM to anyone looking for an excellent company to complete their renovation. Thank you Luke, M... Read more

As you will see from the multitude of reviews on KLM Construction, they bring the highest levels of professionalism, materials, and workmanship to their projects. Our house is about 75 years old, with several rennovations by previous owners, many not well executed. From the beginning Maciej was probing into every crack and crevice and taking pictures to understand the layers of construction. No other company was this detailed. KLM was not lowest price, but they gave us a feeling from the begi... Read more

KLM built our deck. We are very happy with the outcome. Father, sons and crew were wonderful to work with. We would hire them again.

In the summer/fall of 2025 KLM renovated the complete front of our 1980’s contemporary home in Pennsylvania. It was a real pleasure to deal with KLM contractors, both from a planning and execution perspective. Being used to European standards and familiar with many aspects of property renovation we were very happy with the way the KLM leadership were paying attention to our many sometimes very detailed questions. In this process we never felt pressured to close a deal and never sensed frustratio... Read more

KLM offered a comprehensive review of my property and a complete plan from the beginning. I was impressed by the attention to details that others hadn't addressed. All costs were itemized and reviewed. There wasn't any pressure to decide within a certain time frame.The crew was efficient, hard-working and mindful of any disruptions. My home received James Hardie siding, new Pella windows with JH trim, new soffits and gutters. The result is beautiful and I am very happy with it.

The entire process of working with KLM was very smooth and professional. The demolition and construction details were explained thoroughly so we knew what to expect at each phase. We are very pleased with the final results!
