"We hired James, Dan, and their crew for a major deck renovation. The level of thoughtfulness and craftsmanship throughout the project was outstanding. This was not a simple refresh — it involved removing an existing hot tub, renovating a cabana, reworking the deck framing to convert it into a single-level deck, installing a new staircase, and adding a cable rail system. Every aspect of the project was approached with precision and care, and the finished product is without flaw. They were easy to work with from start to finish, handling decisions and mid-project modifications thoughtfully and professionally. The whole crew was consistently approachable and friendly, and clearly took pride in their work. Daily cleanup was always done well, which we especially appreciated since we had a puppy at the time. Definitely recommended!"

With over 20 years of experience, We take pride in quality craftsmanship. We are family owned, and believe in building long-term relationships with our clients by delivering honesty along with exceptional work. We pride our company on reliability, great communication, integrity, and customer service. We are experts in our trade and will do our best to keep you as educated as we can on your particular project. Give us a call today! We look forward to working with you!

"My project was to add a porch to the front of my antique house. I quoted the job out to 3 builders and found the prices all to be similar. Although Fiske Construction was very slightly higher I was impressed with the professionalism of the quote and Mike�s understanding of what I was looking for. I showed him a couple of pictures of the style I wanted and he immediately picked up the details that gave the look I wanted. Mike arranged for the permits and began work as soon as they were set. Mike�s work ethic is far better than many these days, he showed up early and worked hard all day, every day. I never felt that my job wasn�t his top priority. I added a couple of features during the construction , Mike gave me a very fair price on the additional work and arranged for the materials required. Mike is more than just a builder, he is a Craftsman. The fit, finish, and quality of the porch is top notch. I have had neighbors and strangers compliment me on what a beautiful porch and how it looks like it has always been there. It�s not an easy task to add to a house built in the early 1800�s and match the quality of workmanship and style for that period but Mike and his team nailed it, I could not be happier or ask for a single change for the entire project. If I need any building projects in the future I will definitely have Fiske Contruction do the work. These days with some pretty questionable contractors out there Mike Fiske is a shining star and a safe bet for any project you may be"

iCornerstone offers design through construction services and promotes Consumer Controlled Construction as a solution to over-pricing, under performance, unrealistic allowances, and quality issues. We provide designs, labor and material specifications, accurate project costs, camera monitoring, invoice review, project accounting, and construction support that allow the homeowner to act as the general contractor easily and with a minimal time commitment. The first three carry an hourly rate of $100, while the fourth is 15% of the cost of the work as you have defined it. After a free Initial Consultation, we provide a proposal for the cost of our services. Our platform networks regulators, engineers, subcontractors, service providers, and suppliers involved in your project so that everyone knows what everyone else knows, which is the hallmark of transparency and accountability. Everyone is on the same page. Their E-folios resolve the dilemma of "If only I had known, I would have asked." Everyone benefits, and nothing like the platform exists in the industry. Clients must provide us the names of subcontractors we do not know as a means of proving to themselves we do not steer business or have a conflict of interest. This strategy helps our network grow and ensures fairness. Our free, online, Consumer E-Folio / Project Organizer / Property Profile / Research Tool will help you, even if you do not involve us in your project, comes with no strings attached, and respects your privacy. Simply register at icornerstoneinc.com and have fun using it. We claim three remarkable achievements: no client has ever gone over budget; no subcontractor has ever been overpaid or unpaid without cause; and all clients receive the highest quality at the lowest price.

"For our home addition/renovation we are very grateful to have found Richard Connolly and his site iCornerstone. Our vision was a Two-story + basement + livable attic space home addition which would provide significant practical square footage to our existing house and integrate seamlessly with it. We interviewed a number of general contractors but we were overall a bit uncomfortable after the interviews due to gaps in transparency regarding how costs were calculated and how timelines were established, resulting in some lack of confidence. We happened upon Richard’s iCornerstone site via Angies. Richard provided an extremely transparent and detailed description of his unique and practical process, which delivered a set of superb designs along with a truly logical, transparent, and honest listing of costs, both materials and labor, at all stages, and how those costs were derived. Richard also delivered transparency on timelines, and he provided recommendations for all the needed tradespeople that he had historically a close working relationship with; alternatively we could have selected tradespeople of our own choosing. Richard and his process gave us the utmost confidence for proceeding. We proceeded with our renovation under Richard’s guidance and his own crew and the entire process went according to plan with excellent communication, rapport, and confidence at all stages from excavation to final finish work. Transparency, confidence-building, dependability, highly knowledgeable, customer-friendly, and results-oriented are all terms we would use to describe Richard and the iCornerstone process. We strongly recommend Richard for anyone contemplating any home renovation or home addition, large or small."

They completely remodeled our condo including 4 bathrooms, floors, fireplace/hearth, etc. It was a big job and they worked with us to make sure everything came out exactly the way we wanted. The cost was very reasonable."

FAQs for addition to existing structure building service projects in Berkley, MA

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.
