He transformed our ranch into a gorgeous 2,600 sq. foot modern greek revival house and the job took about 9 months. Everyone who walks in is amazed by the detail and quality of Jon's work. Jon is an incredible craftsman and for a reasonable price can transform a modest house into a showpiece. Before hiring Jon we interviewed a few contractors, but Jon was the only one who came with a quote that also had detailed line items that described how much everything would cost and why. Jon is extremely honest and does not underbid or tell the homeowner what she or he wants to hear to get the job, and then raises the price once the job is ongoing. He stuck to the line item numbers he quoted us, unless the scope of work changed, at which point, Jon helped us negotiate with the subs. Will post pictures soon. **★★★★★ — Hardwick Post & Beam, Jan. 2017** > I supplied a timber frame to an addition that Jon was working on and have nothing but good things to say about the experience. Jon was professional, insightful and a pleasure to work with. I would absolutely recommend Jon. > > Christian Gudmand > Hardwick Post and Beam **★★★★★ — tammydevine, July 2016** > My husband and I hired Jon 5 years ago to build our home(dining room picture attached). This is just one small example of the kind of work Jon produces. Since then, he has renovated another smaller home for us and has done a commercial project over 28,000 feet in size. His abilities have shone with both large and small/ residential and commercial projects. By virtue of having hired him repeatedly, the trust we place in the quality of his work is apparent. We always felt Jon had our best interests in mind and he treats every project as if it were his own home. His attention to detail is unparalleled. Jon is one of the kindest, most humble and honest person we have ever dealt with in a professional manner. He is a rare gem and we feel fortunate to enjoy his beautiful craftsmanship. > Tammy and Adam Devine **★★★★★ — Daniel Coughlin, July 2016** > We hired Jon Palmstrom to construct our 4,000 sf architect designed home in Hingham. As a real estate professional, I have worked with dozens of contractors, Jon is at the top of my list. He worked very well with the architect, delivered a very complicated waterfront project, on budget. He stands behind his work, and after 10 years, we are still extremely pleased with our home! > > We were very pleased with every aspect of his work and heartily recommend him ! **★★★★★ — tierhar124, July 2016** > Jon brought our kitchen/first floor renovation to life from architectural drawings ... He and his crew are master craftsman carpenters with an eye for detail. He was involved with every aspect of this project from demo day to the punch list and called or came on site every day... Jon worked well with our architect and kitchen designer ..The subcontractors he hired were professional and timely...His quote for the project was fair and accurate and the project finished on time **★★★★★ — patriciabelanger134, April 2016** > I worked with Jon and his team on a new build south of Biston. > > Jon and his team are consumate professionals. Perfectionists from every perspective. Extroidinarily detail oriented, Result: Perfection.
