What people say:

I think Clemens is an extraordinary, intelligent, interesting man.

He’s one of the most accomplished, creative designers and craftsmen I have ever known. He is reliable, articulate, resourceful, and kind.
Since he worked on two houses over the course of several years and varying projects we have become good friends and I trust him completely. Clemens has not only worked for me, but was also always there to help whenever I had an emergency. If there was ever something he could not help me with, he would help me find someone who could, who he trusted and supervised. He is decent, honest, and fair. If I could, I would only ever have Clemens work on my home, and no one else. He is an extraordinary person, and has a great gift.

I will look around for something that needs fixing and, if necessary, break something just to get you back here.

I consider Clemens and his remarkable range of skills and artistry the very best.

I am extremely pleased to write this letter of recommendation for Clemens Sippel. Over the past several years Clemens has done numerous projects for me in my former coop as well as my current house. When I hire a craftsman or contractor to work where I live, I try to hire only the best and I consider Clemens and his remarkable range of skills and artistry the very best. He brings knowledge, craftsmanship and high standards to any project he is asked to accomplish. This is only surpassed by his energy and his passion for the work. These are qualities that he consistently demonstrates. I recommend him to you without reservation as I have done to friends and associates over the years. I am very pleased to give him my very highest recommendation. He is an excellent craftsman; truly remarkable!

His design sense adds immeasurably to his high level of craft. He is reliable, shows up when he says he will and meets or exceeds expectations.

I’m pleased to write a strong reference for the high-quality work and results I’ve experienced since engaging Clemens Sippel to accomplish repair, restoration and new work at my 110 year old house in a Landmark District in Brooklyn. Mister Sippel has accomplished complex wood-working repairs of floors, windows, doors, trim, moldings and non-wood materials throughout the house. He makes full use of materials already present in the house, only replacing as necessary and then always with closely matched or near identical replacements. His work on carved oak moldings made from quarter-sawn white oak has resulted in the restoration of original details to my home that had been missing for more than 50-years. His creation of an affordable library wall and audio system cabinetry in oak matched to the 110- year-old trim in the room created a comfortable, attractive space respectful of the past and yet serviceable for a family. His practical knowledge of electrical and plumbing issues compliments his general carpentry and cabinet-making skills. His design sense adds immeasurably to his high level of craft. He is reliable, shows up when he says he will and meets or exceeds expectations. When he was dissatisfied with a highly visible portion of the main stair that hadn’t taken stain properly, he pointed it out to me and explained that he would redo the work on his time and at my convenience. Neither my wife nor I had noticed the defect until he demonstrated it. He has at all times been respectful of our privacy and space. He has worked with our dogs around and even let them in and out when no one would be home for a prolonged period. I continue to engage Clemens Sippel for a wide range of projects around our home.

Clemens is a true artist who has turned his artistic eye and creative energy to furniture building, carpentry design, and interior renovations.

I am writing to highly recommend Clemens Sippel. Clemens is a true artist who has turned his artistic eye and creative energy to furniture building, carpentry design, and interior renovations. Everything he has built for our house is quite literally a work of art. From exquisite radiator covers, to closets, to furniture in our living room, whatever Clemens creates imbues an incomparable sense of elegance and style. Clemens has a rare ability to listen to and understand what his client’s wants and needs. He will work closely with you, designing what you want based on what he perceives about your living space, your desires, and your personality. He is a joy to work with, with a gentle, lovely demeanor that takes away any difficulties in a decision-making process. Any sort of construction usually incurs a certain amount of mess, which can lead to stress in a household. Clemens is acutely aware of this, and so he’s very respectful and neat. He cleans up fastidiously to the point that it’s hard to believe he’s done so much work in your home! He works diligently, and always delivers what he promises in a timely fashion. I cannot say enough good things about Clemens.

He exceeded our expectations while remaining true to his cost estimate and schedule.

Clemens Sippel has worked on several renovation projects for my wife and I, both in our Brooklyn brownstone and in our Manhattan studio. In each case, he exceeded our expectations while remaining true to his original cost estimate and schedule. Whenever we have work to be done, he is the first person we think of, and if he is otherwise engaged, we are always willing to wait until he becomes available. There are many reasons why he is far and away our first choice for any sort of renovation. He is undaunted by the unique difficulties of any task. In fact, he seems to enjoy the challenge of coming up with elegant, innovative solutions that stay within budget parameters (He will often give different cost options to choose from). When he builds something, it stays built. His work is not only aesthetically beautiful, but also solid and durable. It’s of the greatest importance to him that Clemens’ clients are completely satisfied with his work. Therefore, he does as much of it himself as he can. When he does oversee the work of others, he makes certain they are as reliable and meticulous as he is. Finally, he is a pleasure to work with. His ideas and suggestions are always interesting and often turn out to be better than anything we envisioned ourselves. He understands the value of repeat business and strives to create enduring relationships with his clients. If he’s available when you call him, talk to him, discuss your project, then don’t hesitate — HIRE HIM! You will not regret it.

Clemens’ expertise, patience and humor have taken the terror out of Home Improvements for us.

Clemens Sippel was recommended to us by a friend in 2002. From the very beginning we were impressed by the excellent quality of his work, by the absolute trust in him personally (he was alone in the apt and had all our keys), by his fair prices and by his impeccable clean-up at the end of the day. Because of him, we started tackling projects that had been on the drawing board for years. Once we had the right man, we knew it was the right moment. We now keep an ongoing Clemens List and plan ahead to reserve some of his time every year. Clemens’ expertise, patience and humor have taken the terror out of Home Improvements for us.

We’ve hired Clemens over the past ten years for everything from small repairs to the total renovation of a bathroom.

Clemens Sippel has done some of the finest work we’ve ever seen on our Brooklyn brownstone, and we highly recommend him for any kind of repair or renovation. We’ve hired Clemens over the past ten years for everything from small repairs to the total renovation of a bathroom. That bathroom was gutted down to the studs and joists and built back up from scratch, and the job included everything from in wall plumbing, installation of flooring and walls, installation of fixtures, lights, and hardware, rehanging the door, and the detailed tile work covering the floor and walls, which was custom designed to our specifications. To this day, all the work has held up like new. Clemens is reliable, exacting, dependable, and a pleasure to work with. We have trusted him with a huge variety of tasks maintaining our 120-year-old home. He is a perfectionist in the best sense of the word, and we have no hesitation recommending him for any job he’s willing to take on.
