From energy-efficient windows to attic insulation, we have energy-saving products to help lower your monthly power bills. We not only offer industry-leading products, but our installers are certified by the Building Performance Institute (BPI) to provide energy audits for homes and businesses. This means that our credentialed auditors can come to your home or office and perform and audit to determine weak spots in your home's insulation and overall energy efficiency. This analysis better informs you and our installers about the type of green home improvement products you need and how to correctly install them to maximize your potential energy savings.

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. \nKesselman 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. \nThere 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. \nOur documents solve thousands of questions and become the basis of a solid legal contract. \n

"Tim is amazing. I was days from closing on a house when the underwriter decided a structural engineering report was required so I called and spoke with Tim on a Wednesday evening, met with him Thursday morning and had a report in my hand by Thursday at noon, less than 24hr turnaround! Needless to say Tim really helped me out and was very courteous, knowledgeable and professional. He will always be my go-to structural engineer."

Structural Engineering FAQs, answered by experts

Proper licensing and experience in residential and commercial structural projects.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

Most load-bearing walls are exterior, though they can also be interior.

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)
