About

Est. 2007. Every project is performed by a licensed structural engineer. Deck design and permit drawings Structural assessments Additions, open concept beams, & permit drawings Structural assessments from storm damage, prior work, age, etc. Home Inspections Home Inspection Repair List Estimates Commercial Inspections Beam Sizing & Open Floor Plans Remodel Permit Drawings Structural Damage Repair Plans Basement Water Mitigation Plans Foundation Inspections Foundation Certifications Retaining Wall Design & Permit Packages Pool Installation Zoning & Building Permit Packages Manual J HVAC & Duct Sizing Calculations Please note, in accordance with the New Jersey Professional Services Act, licensed engineers can size and design engineered systems in a home (such as structure, plumbing, septic, pools, and HVAC), but not the building itself. Only a registered architect can provide plans for a new home. Also please note we are not surveyors. If you want a property survey, please list your project under the surveyors service section. Also please note that structural engineers work on a fixed-fee basis. When ThumbTack lists "$1-onsite estimate," that does not mean we come out to your home to provide a professional opinion for $1. That message was originally intended to apply to contractors like painters and landscapers, not to engineers and architects. Engineers and architects will provide an up-front, free proposal for your inquiry, but our in-the-field real estate due diligence assessment services and structural repair cost reports are not $1.

We had an outstanding experience working with Oak Ridge Engineering LLC on the structural assessment for the property at 117–119 E 26th Street, Paterson, NJ. The report was exceptionally thorough, clearly written, and professionally prepared from start to finish.

Darren was fantastic. My fiancé and I are in the process of possibly buying a new home that had some structural defects. He was so thorough that he found more than what we initially thought. He was able to answer all of our questions in detail. He also did more than what we initially asked him to do and gave us so many suggestions and possibilities for certain things. On top of this as promised he got our report to us the next day. While I hope we never have to use his services again, if we don’t decide to buy this home we will definitely be hiring him. Thank you again Darren!

FAQs

What should the customer know about your pricing (e.g., discounts, fees)?
We provide competitive pricing, and include a full structural assessment with our home inspection fee. In addition, if you're not getting a structural assessment by a licensed engineer as part of your home inspection, you could end up scrambling for one as your due diligence window closes.
What is your typical process for working with a new customer?
We like to ask about a few details regarding the property, and we like to hear from you if you have specific concerns.
What education and/or training do you have that relates to your work?
I am a licensed professional engineer and licensed home inspector. I have inspected properties as small as a studio apartment, to large iconic structures like the Chrysler Building and the Irving Trust Building.
