Client Stories and Completed Home Additions

“Lynch Design built my amazing kitchen add-on! From consultation to planning and building, Lynch went the extra mile to make sure everything was done the right way and that we were happy. We have been spending most of the day in our wonderful new kitchen add on. Thank you Lynch Design!”

– Rommel Zara

“The time line of the job was posted to us before work began. Work started as scheduled and was completed according to the schedule. The workers were all very professional and respectful of our home. A days work was always completed with a cleanup of the site. The carpenter is an excellent craftsman. The tile man is an artist and did an excellent job on the tile floor and backsplashes. Our new kitchen blends well with our home. The project was finished on time. We are very happy with the finished product.”

– Alice Armour

“Lynch Design/Build constructed an in-law quarters addition to our 1932 stone house. Our goal was to have both the outside and interior of the addition reflect the quality and appearance of the original house. Their team got it and delivered just what we wanted.”

– Paul Wiedefeld

“We had a great experience with Lynch and will be happy to work with them again on future projects. They handled a full service design and build project - replacing a rotting deck with a gorgeous screened porch. We are so happy with the results! We basically spend all our time out there when the weather allows. It has been finished about 6 months now and we are still loving it and appreciate the quality workmanship.

From the beginning they were nothing but professional and courteous. I appreciated that they were patient with my design re-dos, flexible with working with our budget goals, and responsive and reliable. They always cleaned up their sites and kept things safe for my little kids and dog and somehow they managed to keep all the muddy footprints off our carpet. They didn’t hesitate to address any concerns that came up and remedy any issues. They definitely seemed to “get” the struggles of a busy family and worked around us effortlessly while minimizing disruption to our routines. Thanks guys!”

– Josh & Vicki Wolf

“Lynch construction did an amazing job on our house. We had a new living room, screened in porch, raised deck and storage space added onto our house. This was a huge project and we are very happy with the final result! Jerry was an excellent communicator and made sure we were aware of everything going on each day. Every contractor that came to our house was polite and professional. We would definitely hire them again for any projects in the future!”
