KLM was a very impressive contractor to work with. The initial discussions showed their depth of expertise. The design and selection process was smooth. The installation was done promptly and professionally. We are thrilled with the results!

Work done with the utmost care, securing windows against possible leaks also done perfectly! Maciek and his employees are very nice, helpful with manners... if you are looking for the highest quality and the best service - I HIGHLY RECOMMEND!

My project was to improve and update a house built in 1973 for our family to live in. I am fortunate to have been able to work with KLM Contractors. The finished project is an amazing transformation and the process was an enjoyable experience. Each and every aspect, from repairing wear and tear from the past 50 years to the new finishing details was done to the highest standard. The flow of the work, once started, continued without interruption. All materials necessary, including those needed for repairing the unexpected "finds" associated with an older house, arrived on site in an impressive logistical flow. I appreciate how well KLM runs their business. Every person had I had contact with clearly cares about what they are doing. Thank you!

We first reached out to KLM to do our James Hardie siding in spring 2020 however due to the covid shut down we decided to hold off. Fast forward to fall 2024 and they’ve just finished an absolute masterpiece of a job. Despite material costs skyrocketing since then due to inflation (which increased our project cost by easily 40%) it was well worth every penny. We were impressed and put at ease with how knowledgeable Maciej and Luke were and felt immediate confidence in their expertise and advice, even down to suggesting the color. I’m a very skeptical person by nature but never once with Luke or Maciej did I feel the slightest indication that they were being anything but completely honest and authentic with us, a total class act. I work in a field where I repair and customize brass musical instruments so I have an obsessive eye for quality and craftsmanship. The level of detail on every facet of our house, even in spots that are almost impossible to see, were impecible. They had multiple crews working who all specialized in different areas and were all meticulous & clearly experts in their specific skillsets. They worked into the evening almost every day and their professionalism was more than we could have asked for. We were honestly expecting our house to look like a war zone until it was done but at the end of every day the crew took the time to pick up every speck of debris, pack everything up and even sweep! I know this all seems over the top but honestly, as with most homeowners who go into renovation projects like this, it comes with a lot of anxiety and stress but with KLM that all quickly evaporated. To summarize we feel incredibly fortunate to have found Maciej & Luke and look forward to working with them on our future window replacement and deck projects. We won’t be shopping around this time as we know we’ll get artisan level work at a fair and honest price. They may be hard to reach sometimes but rest assured they will always get back to you. They’re a small family business and are extremely busy so be patient, hang in there, trust me you’ll be glad you did… I know we are.

I would absolutely recommend KLM to anyone who is looking for true professionals, from start to finish. Their attention to detail was impeccable, and the quality of their craftsmanship is evident in every corner. They went above and beyond to ensure my satisfaction, even taking the time to clean up after themselves. I would highly recommend them to anyone looking for top-notch home improvement services.

I spent a lot of time doing research on contractors and we are extremely pleased with our decision to go with KLM they explain the process and have a great attention to detail. I would highly recommend them.

I have every confidence that this company can design, quote, work and complete any project that you give them.

When you find a contractor who knows their job and actually completes the work you contracted for...you share them with everyone who asks, even if they don't need them right away.

KLM is courteous and professional.

I was an educated consumer/quasi-stucco remediation expert when I realized that I had a significant stucco/water penetration issue at our home that was built 33 years ago. Unfortunately, I saw way too many stucco repair projects where purported stucco contractors were merely fixing the cosmetic issues at the home, without addressing the root cause of the problem. When you don’t fix the root cause of the problem, the moisture issues will resurface in time. I have seen it time and time again.

I interviewed a lot of stucco contractors and received formal Proposals from most. When I met with Maciej and questioned him thoroughly while walking around my house, he quickly Aced my test questions. He clearly understood the difference between performing stucco repairs at my home and remediating the issue. KLM will likely not be your cheapest option, but they are thorough, professional and their crews are the most professional in the industry and the work they do is impeccable. They have expert crews who handle specific aspects of each part of the remediation project. They have specialists.

One crew is solely responsible for installing the scaffolding. Another performs the removal of the stucco. Another repairs all of the rotted wood and wraps the house. Another handles the removal and installation of any windows and doors that need to be replaced. Another Crew handles the installation of the siding. Another crew handles all of the finish work. All of the work was expertly performed. The Crews were amazing and did their best not to disturb our busy lives in the almost three months that they were at our house. We had no issue giving them access to our home while we were at work.

Our house had extensive water penetration damage, as anyone can see from the project photos. BTW - the Crews took photos every day showing the issues with the house and how they were fixed. Many contractors told me that they didn’t need to pull the windows, even though the root cause of much of the water penetration was due, to a great extent, from the builder improperly flashing the windows. Don’t for a minute think that you can resolve the water penetration issue without pulling the windows.

Our house is now watertight and beautiful. KLM took all of the necessary steps to correct the issues with our home. Neighbors now walk by our house and compliment us on how beautiful the house looks. We choose Hardie Board for our siding and couldn’t be happier.

Too many people to thank for the excellent work performed by KLM. Maciej and Luke handled the logistics perfectly and were responsive to all of our questions and concerns. Their Team Rosters are filled with All Stars. Special thank you to Luke, Raynor, Albert and William. Without any reservation, I would strongly endorse KLM for your remodeling project. You will not be sorry. Make sure to ask yourself when looking at contractors whether you are looking to make the best decision for your home and your family by contracting with a reliable, A+ rated company like KLM. They will provide you with the best value, the best quality and will solve your problems. Go with a professional remediation company, not am amateur stucco repair company.

kLM is an excellent company . They hire very competent workers that are meticulous in making sure the work is done correctly .

KLM contractors were courteous and professional. They did an excellent job.

Recomending them to neighbors and friends.

Absolutely, I’ve already referred neighbors, friends and clients.

High quality work

KLM Contractors did a beautiful job, was very thorough, and addressed concerns.

Note: We had a remediation, repair and renovation project that was more complicated and extensive then most -- 100% of exterior (stucco removal, roof down to foundation, all doors, all windows, two portions of basement, entire garage interior, new in-law suite in basement, plus other elements.

Excellent quality work. They possess a strong understanding of construction and how to fix underlying problems. They were flexible and worked to address some unusual and specific needs. In some aspects, such as how they built my deck, the attention to detail was truly impressive.

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. We will be working with them again!

KLM Contractors did a fantastic job, were very professional, and we are very happy with the result.

We had a successful experience with KLM. This is a family run business and each work together to ensure that the project is moving along and troubleshooting any issues as they arise. They are very interested in ensuring that the customer is satisfied and pleased with the work and will provide options to accomplish a particular design goal. They are passionate about the work that they are doing and want it to be of the highest quality. They provide options on how to approach the project and have a good eye for design.

I hired KLM to complete the exterior siding, and windows on my home after I signed a contract with with another contractor for the interior renovation. The difference between KLM and the other contractor was noticed in every area of the renovation. KLM was timely, the workmanship was excellent, their workers cared about the end product. They follow through on everything they said they were going to do. They came early in the morning, 830 and worked until dark. This was in February. I’d like the relationship that I developed with both owners of the company they listened, answered all my questions, and took the time to discuss the job whenever needed. I have hired many contractors over the years, but I would put KLM at the top of the list.

The KLM team is definitely providing a premium product. Every member of their team is experienced, professional and meticulous. Their results exceeded expectations. Yes, it was a construction project with it's share of challenges, but KLM was on top of things at every step, and we couldn't be happier with the results. Our house is and looks much better than new!

They did great work. I enjoyed working with the team. They were sometimes hard to reach, however.

KLM did an incredible job on our recent renovations. We couldn’t be happier with our ‘new’ home. We will be recommending KLM to all our family and friends!

KLM is first class all the way. They thoroughly know their business, have very good ideas, solve problems and the family truly cares about doing the job right. The crews are top notch. They met and exceeded our expectations. They have pride in their work. We love our house which is now better than new.

Excellent service from start to finish.

KLM is the best contractor I have ever dealt with for home renovations / repair.

KLM completed an extensive renovation of the exterior of our home and were an amazing company to work with. They are professional, friendly, collaborative and do fabulous work. Their expertise and quality exceeds expectations and they provided valuable advice during planning and as the project advanced. All of the workers that complete the work 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.

Great service, great price, fantastic crew, and excellent customer service

We were thrilled from start to finish. We've already recommended KLM Contractors to very close friends and we would not have done that if we did not love what they did. By the way, my brother used them and that is how we found out about them. We have nothing but praise for this outfit.

They were a pleasure to deal with.

Cannot say enough about the owners and every team they sent to my home. By far the largest and most painless renovation we have undertaken because of them.

Areas Of Satisfaction - The workmanship was excellent. The owners were constantly on the site to check the work and answer my questions. We feel that they incorporate good materials with sound water management. No short cuts were taken- they want the job done RIGHT!!! A great experience!!

My husband and I were extremely satisfied with KLM Contractors for their recent construction job on the exterior of our home. They removed the stucco which was failing in parts and applied Hardie Plank siding. They did additional trim work around the windows and garage area as well. They paid careful attention to detail throughout the project and their handiwork was exceptional. They were very reliable and efficient, always showed up to our house as scheduled and completed phases of the job in a timely fashion. Finally, we really appreciated how everyone we dealt with was very responsive to answering our questions and making changes as the project progressed. We have no hesitation recommending KLM Contractors for all your remodeling needs!

Outstanding workmanship; 5-STAR, TOP QUALITY PRODUCTS; EXTREMELY PROFESSIONAL Contractors!We HIGHLY RECOMMEND KLM. The team explained the stucco remediation process in great detail. We were introduced to products that fit our budget and were shown the computer-generated design of our home before the renovation began. The team is extremely professional and cared for our home as if it were their own. The design consultant spent many hours with us to make sure the project went smoothly. We were so impressed by KLM, that we would like to use their expertise to complete another home renovation on our shore home. After 25 years of searching, we finally found the best contractors in the entire region.

We were very impressed with the quality of work and the positive experiences shared by other neighbors in our development. When we finally decided to remove the stucco and replace the entire exterior of our home with Hardie Board, plus a new roof, to ensure future resale, we felt confident hiring KLM Contractors to do the job. Maciej was very informative and professional with the initial presentation of the process and estimate. Luke oversaw the project with skilled teams in each specific area of the renovation, and all were a pleasure to work with. The crews showed up bright and early and stayed until our home was cleaned up and organized each night. Luke let us know if there was going to be a weather issue or delay and would come by to inspect the progress. They always went the extra mile to make sure we were happy. We trusted and appreciated Maciej and Luke's advice with color and finish selections to coordinate with our original stone accents, as we would have chosen differently. They were right and our house looks great! We would highly recommend KLM Contractors! Many thanks from Kevin and Peggy M., Doylestown

KLM is a great company to work with. They make sure the customer needs are at the center of decision making as the project is being planned and executed. I would definitely do business with them in the future and would recommend them highly.

We feel like the KLM owners and team members have become "like family". One could not ask for a nicer and more professional group of people. Maciej, Luke & Chris took great ownership and pride in the project. They provided guidance & solutions when they ran into unexpected issues explaining the options in detail and we never felt like they were piling on additional expense. With the size & scope of the project from planning through completion they managed the process; people & challenges never missing a beat. Very smooth flow. Our project included: whole house removal/repair/residing; all doors replaced; new deck; one deck removal; added window; repaired plenty of damage; chimney repair & repointing & overall painting. We were thrilled at the frequency & level of involvement from all three - Chris; Maciej & Luke.

Professional, clean, with a high attention to detail. Recommended.

Areas Of Satisfaction

Areas Of Satisfaction - They honored their word and finished the job to the very last detail.

Use Comments

Use Comments - We interviewed several contractors about our home improvement project, and we definitely wanted to pick the right one for such a large project. We chose wisely, and we whole-heartedly recommend KLM! Without a doubt, they are professionals! They totally exceeded our expectations-they worked tirelessly on our home, and as a result, we gained an excellent result! KLM was the best contractor for our home improvement project.

KLM Contractors is the kind of home renovation company that you expect to contract with but rarely do. From the first moment of the engagement they help you design your dream modifications, thoroughly quote your job, and then help to meet your budget needs, KLM is outstandingly professional and easy to work with. Once they commit to your job they schedule each phase, they show up when expected and work to completion. All work is top quality, impeccable and makes your house the showcase of your neighborhood. You don't have to chase them, they frequently ask how things are going, their ownership is present at the jobsite daily quickly responding to your needs. There is not another contractor working locally doing large renovations who better stands up to their commitments while minimizing the stress of all the activity going on during the renovation. You may pay more (probably not) but you will get quality work that is backed by their warrantee directly by the ownership. Do not pay less and think you are getting a bargain. These contractors are not all alike. With KLM you get what you pay for and much more!
