A Family Team Focused on Your Home
Careful Exterior Renovation Since 2002
KLM Contractors is a family-owned renovation company based in Doylestown, serving Bucks County, Pennsylvania, and neighboring New Jersey since 2002. We work with homeowners who want a thoughtful design, careful preparation and a clear understanding of the investment they are making in their home.
The conversation starts with your goals and the existing exterior. For a larger transformation, renderings help show the proposed products and colors, while a written proposal explains the materials, scope and known preparation work. Specialist crews then handle the relevant phases of the renovation in a planned sequence.
If the work reveals concealed damage, or you decide to change a detail, we discuss the adjustment and its cost for approval before proceeding. Careful work and fair, itemized pricing are central to the process.

Siding
James Hardie fiber cement siding installed by an Elite Preferred contractor, with attention to the walls, flashing and water-management details beneath it. Compare profiles, colors and trim as part of the design. Vinyl siding remains another option within our siding services; product warranties depend on the selected system and written terms.
Windows
Explore Pella and Okna window options with attention to style, operation, glazing and installation. The opening, flashing and integration with the wall are part of the project, not just the window itself. Compare the specific product and installation approach for your home.
Decks & Outdoor Living
Composite and PVC decks, covered porches and pergolas planned around how you use the outdoor space. Compare the layout, framing, stairs, railings and finish materials together. The right scope starts with the existing conditions and your goals for the space.
Roofing
Owens Corning asphalt shingles, standing-seam metal and flat/low-slope roofing options. The roof covering must suit the slope and assembly, with attention to the deck, flashing, drainage and ventilation where applicable. The proposal identifies the selected products and warranty terms.
Stucco Remediation
Stucco remediation addresses the wall assembly and the causes of moisture problems, rather than only covering a visible blemish. The work can include stucco removal, repair of damaged sheathing or framing, and reconstruction of flashing and the weather barrier before replacement cladding is installed. The scope depends on what the assessment and opened wall reveal.
Design, Preparation and Clear Communication
Why Choose KLM Contractors?
The proposal, the preparation and the people doing the work all matter. Our family stays involved as your renovation takes shape.
A Considered Design
Discuss products, colors, proportions and how the changes fit your house. Renderings help make a larger exterior design tangible, and the proposal defines the work before construction starts.
Fair, Itemized Pricing
Compare the materials, preparation and responsibilities in the proposal as well as its total. Requested refinements and discovered conditions are discussed and priced for approval before the changed work proceeds.
Preparation Comes First
A new finish should not conceal an unresolved problem. On siding and stucco projects, exposed walls are assessed and the necessary repairs, flashing and water-management details are addressed before the new cladding goes on.
Specialist Crews
Larger exterior renovations involve distinct phases, from removal and wall preparation to installation and finishing. Luke coordinates the crews and sequence for the actual scope, while the family stays involved in the project.
Plan With Confidence
Is KLM the Right Contractor for Your Project?
If you value a considered design, careful preparation and a clear explanation of the work, our approach may be a good fit. Tell us how you use your home, what you want to change and how long you plan to stay. Those goals help shape the discussion; they do not replace an assessment of the actual project.

Frank Poiesz — Jamison, PA
"KLM completed an extensive renovation of the exterior of our home and were an amazing company to work with. All of the workers are employed by them, specially trained, and work is closely supervised along the way. Their business model and philosophy is best-in-class. I would highly recommend them without hesitation."
Robert Ferlauto — Neshanic Station, NJ
"KLM is the best contractor I have ever dealt with for home renovations. Great quality of workmanship, great work ethic, friendly skilled workers, and a fair price for the work. Could not be happier with the work done by KLM. These guys are the best."

Bernadette Putz — Doylestown, PA
"I was impressed with how sincere Maciej, Luke, and Kris are about making sure the homeowner is happy with the final results of the project."
Kimberly Contey — New Hope, PA
"I cannot say enough about the quality and professionalism of the work of KLM. They were extremely easy to work with. All of the crews were meticulous and thorough in doing their part. This has been the best experience I have ever had with contractors."
Jeffrey Fine — Newtown, PA
"KLM was terrific. Their team was very professional and courteous and extremely competent. They paid attention to detail and made great suggestions within our appetite and budget. Maciej was very patient during the sales process. Kris and Luke were on the job site often and worked closely with us as we developed the details. We will be working with them again."
Peter LaPlaca — Doylestown, PA
"From the moment you sit down with Maciej to decide what KLM can do for you, the organizational skills are evident. You receive a rendering of your final project and an extremely detailed written contract complete with illustrations, warranty statements, and costs. Luke follows that up with scheduling all the crews — there is a different crew for each element of your project — so that nothing is overlooked."
Robert & Joyce M. — New Hope, PA
"A delight to work with. Very high quality work, highest integrity people I've ever encountered in construction. They made excellent recommendations along the way to optimize the outcomes and appearance when issues or opportunities came up as remodeling progressed."
John Skolas — New Hope, PA
"We ran into issues with failures behind the existing wall — KLM was able to quickly diagnose the problems and pivot to address them. We couldn't be happier with our 'new' home. We will be recommending KLM to all our family and friends!"
Kaitlin Masterson — Sewell, NJ
"I loved the attention to detail. They were easy to work with and the house turned out stunning. This company does not nickel and dime you for any changes you may have."
Amber Lavalle — Warrington, PA
"Solution-oriented rather than problem-oriented. Quality of craftsmanship, flexibility to adjust and modify, attention to detail, great listening skills. Every single crew did an excellent job."
Diego Restrepo — Doylestown, PA
"The overall communication was well done. It is not something I have had good experiences with in the past with other companies, and communication is normally a problem. They had a good cadence of communication throughout the process."
Stephen Knorr — Doylestown, PA
"Having worked in the home improvement industry in my 20s, I was very impressed with the workmanship and attention to detail the crew took on my house. I felt they went over and above in many areas of the project."
Geoffrey Prudhome — Pipersville, PA
"I never thought my home would look so good. The use of different colors and moldings really make the finished product pop. Creative ideas, clean workmanship, and extra attention to detail."
James Sanocki — Doylestown, PA
