"When we first met with Lew Merryfield, our home was a disaster.  Smoke and intense heat had made it necessary to completely gut and restore our home.  It was a time of great despair and confusion.  Lew was very reassuring that his company would be able to handle to assignment and allow us to return to a home that was better than ever, and agreed to bid the job in the format requested.
After the contract was signed the Merryfield Construction Group was very active, and progress was made every week.  We opted to hire our own subcontractors for plumbing and HVAC, and an electrical contractor recommended by the provider.  The provider and their staff worked well with the other contractors and were communicative with us during the process.  A promise to never abandon working on our home for any significant period of time was kept.  Building options and recommendations were presented at appropriate times and were appreciated.  Lew and his brother George worked with us to solve problems that arose and we always felt like it was a partnership and that they took great pride in their work.  Additional work outside the original contract and work change orders were appropriate and reasonably priced.
The fire was one week before Christmas in 2013, and we were able to move back in late October 2014.  Although this time frame was slightly outside of the original estimate, it was not considered unreasonable given the nature of the work and the change orders. After we moved in, the provider has done a nice job on following up any problem areas and punch list items.
We are very happy with our "new" home and are confident that the provider will continue to stand behind the work.  The overall job turned out much better than we could have expected.  Lew and George Merryfield, and their staff, particularly Tom Ferry, Sean, and Scott, were always respectful and friendly, and took obvious pride in their crafts.  In conclusion, we are glad we selected Merryfield Construction Group and would not hesitate to use them again in the future or recommend them to others."

"The fence was installed satisfactorily, but we requested a certain kind of post caps but were given another (not a huge deal, but still we didn't get what we asked for). But, because the fence abutted our basement bilco doors they had to remove one of the door handles. They proceeded to break both of them. I reported this to the company and they asked that I send pictures, which I did. The company has never replaced or compensated me for the broken door handles.

"Bob and his crew did an outstanding job on all three projects.  The first shed foundation required a lot of front end loading work with the township and Bob helped me navigate the process.   All of the jobs required significant travel for Bob and his crew, but they arrived early everyday and worked long into the evening.  Bob pays attention to the details and does not cut corners.  His rates are competitive and you definitely get what you pay for.  I highly recommend using Rock-A-Fellas for your next foundation or shed project.

"Since we are looking in to buy in Ohio, Mark could not work with us due to not being licensed there.  He was very helpful and spent several minutes on the phone answering questions and helping me understand a couple different unconventional loans.

"Our first meeting with Yakup Koksaldi, the President of t h e company, was very productive. We told him what we wanted and he sat there and drew up the plan exactly the way we wanted it to be. He was cool and professional and never once pressured us. He was honest and gave us good advice. We did an addition (23'x14'), with an A roof. They started work in June 2016 and completed the job by mid August 2016. The work was neatly done and up to code. From the foundation to the roof, the skylight, the energy efficient Windows, the heating system, laminate flooring, electrical system and light fixtures . Everything was done with great professionalism. The workers were polite and worked effortlessly. We are very pleased with the outcome of our addition. Since completing this job, we already had them come back to do a small project. We have recommended them to our friends because our friends just love our addition. We can't wait to start a new project with them. They are,certainly the best."

"Michael Patrick Construction was great working with from start to finish. Matt met with my wife Michelle and I and we went over the details of the project with us and made the process very easy. The crew who built our deck were great. They showed up on time and were very polite and professional. Frank was the lead for the crew and he answered any questions I had and helped me out at the end of the project with getting our pool steps anchored to the new deck. We appreciate everything Michael Patrick Construction did for us. We can’t wait to enjoy the rest of summer soaking in the sunshine poolside! You guys are great! Look forward to working with you again in the future."

"I'm not a big writer but have dealt with contractors for more than 35 yrs. Believe me I am probably not the easiest to please BUT had absolutely no problems. Courteous, professional and the quality seemed far better than the price we paid. I have other projects on the horizon and believe me Dustin will be getting my first call."

FAQs for shed, barn or playhouse building service projects in Williamstown, NJ

Most sheds larger than six feet by eight feet require a foundation to remain level and dry. A compact tool shed might get by without one, but anything heavier should sit on at least a 4-inch-thick stone-and-gravel pad that extends two feet past the walls. The gravel protects wood skids and promotes drainage. If you want maximum stability—and your budget allows—a poured concrete slab is the strongest option.

Your ideal shed size hinges on purpose. A common 10-by-12-foot kit gives you 120 square feet—plenty for lawn tools and bikes. Need just a spot for a mower and a few rakes? A compact 4-by-7-foot model should work. If you’re envisioning a workshop or hobby room, look at 12-by-16 feet or larger.

A good rule is to raise the shed floor four to six inches above the surrounding soil. That clearance encourages water to drain away instead of pooling beneath the structure. The simple step is especially important for wood floors and skids, helping deter rot, mold, and insect damage while extending the life of your new outbuilding.

Choose the route that fits your goals. Prefab sheds arrive in standard layouts and go up fast—perfect for basic storage on a tight timeline. Custom builds cost more and take longer, but let you add windows, wiring, plumbing, and unique finishes. Balance budget, features, and timeframe before deciding which type of shed is best for your needs.
