"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

"I hit the jackpot when I chose Bob Ayotte to build my accessory dwelling unit in my son's 2 car garage. I should have purchased a lottery ticket! He is honest, a perfectionist, neat and very knowledgeable! Most impressive for me was the fact that Bob took the time to listen and understand what I needed to make this dwelling my "forever place" now that I have retired."

"Corey and his team are great to work with. He is a prompt communicator and is very organized. He also has a great attention to detail and ensures the project is perfect before claiming he is done. He is easy to work with and was able to make our ideas a reality. We have used him for several projects already and have him lined up for another. I highly recommend St. James Construction."

"Phil coordinated and supervised the entire roof repair and shingling of our 200 year old house. He then stripped the clapboards to bare wood, replaced broken clapboards as well as soft wood behind some of them, before applying 3 coats of paint to the entire house. Phil told us up front that he took his time to do it right and would not be applying paint within three days of it raining., to ensure there would be no moisture under the paint. The work was done meticulously, with care taken to avoid any spillage or leftover material. I wish I could provide some photos to show his work!"

"JWC builders are seasoned contractors. They do amazing work! They show up on time, and work throughout the day. The owner of the company, John Wrobleski, was always in contact with me, letting me know what was going on throughout the course of the deck building project. I have hired them for many other jobs as well and they always do an impeccable job! I will definitely hire them again for future projects!"

FAQs for addition to existing structure building service projects in Hollis, NH

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
