"Would highly recommend Jason and Blue Mountain. We recently used him for a master bedroom and bathroom remodel as well as renovations to our screened in porch. Jason was responsive and communicated with us every step of the way. He met the timeline and deadlines that were set for our projects. Jason and his skilled employees were friendly, courteous and a pleasure to have in our home. Their work was meticulous and they cleaned up every day before leaving our home. We are thrilled with our upgrades and have future projects planned with Jason and Blue Mountain Building."

"I can’t say nice enough things about the process of working with Martin. We decided to finish our basement, including a full bathroom, while I was pregnant and wanted the job wrapped up before the baby came, which gave a very hard deadline. Not only was Martin able to work with us contacting him two months out on this project, he was so responsive during the process, gave us great ideas, and kept us well-informed on everything that was happening with the project. From start to finish, we always felt that Martin was knowledgeable about what he was doing and didn’t seem bothered when we had last minute changes. The entire team was so clean, which gave me comfort given that I was pregnant at the time, and they were able to complete everything before the baby came. If I had more basements, I would definitely call Martin!"

We provide architectural, structural, and mechanical engineering services, utilizing over 30 years of experience in technical design, construction management, and design build services. We "listen" to our clients and solve and implement creative designs based on their needs. Kesselman Architectural Design, LLC services all of PA, NY, and MD. Typically, a set of construction documents requires only one on-site visit to gather on-site environmental and existing building conditions. We find communication on most projects, whether local or distant, is usually completed via phone and internet. There exists a triad between 3 major project aspects as quality, time and cost. A successful project requires a balance of the three. A well detailed set of construction documents will allow contractors to bid on the same "scope of work," competitively, thereby saving time and money. Our documents solve thousands of questions and become the basis of a solid legal contract.

"I got lucky. I found Lynn on a website and he was the only one with all 5 stars...now I know why! He was so wonderful to work with; knowledgable, responsive, and patient as they come. He worked within my budgetary requirements and even recommended a builder that I decided to work with. I cannot say enough great things about Lynn and highly recommend him to anyone looking for the best architect! If I could give him 10 stars, I would!"

They completed our deck in less than a day despite some light rain, and most importantly it looks great! They were also able to get the project done a week earlier than expected when we had originally booked it (Lee notified us a few weeks in advance that they could move the project up)."

Custom Home Builders questions, answered by experts

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.
