"I called Bruce Ensor after my home inspector noticed that a large number of joists in the basement had been "repaired" in an unconventional manner.  We were concerned because the affected area was extensive and there was evidence of floor movement and sagging in the floors above. Approximately sixteen joists in the basement appeared to have been repaired using a smallish metal bracket apparently for the purpose of adding strenght to the connection between 3"x10" hardwood joists and the stacked rock foundation wall.  In addition my home inspector found about 4 joists that had evidence of rot. <br />  B E Structural Engineers are HEROES!  They promptly answered my phone call.  I was able to describe my predicament to Bruce and we scheduled a visit by one of his engineers for the following day.  Ken arrived exactly on time and spent a generous amount of time inspecting, photographing and mapping out the affected areas.  He immediately was able to determine that the brackets were simple aluminum angle bars.  Clearly these were inadequate to take the amount of weight and stress required if a joist became badly rotted. <br /> For more than an hour, Ken and I jointly inspected the basement, the two floors above and a walkway on the north side of the building which was where water was entering the building and had begun to affect the joists.  Ken outlined two potential methods for making repairs.  He estimated costs in a methodical manner and we agreed that the repair would need about 120 man-hours to accomplish.  This, we realized would exceed $10,000.  He told me that he would write up his inspection report, discuss his findings with Bruce, and that I would receive a written report in about 48 hours.  <br /> Subsequently, I called and spoke with Bruce Ensor in an effort to speed up the written report.  Bruce spent a half hour on the phone discussing the problem that the proposed solutions.  The cost estimates were slightly revised and Bruce sent along his report, cost estimates, a drawing of the affected area and the photographs. <br /> The documentation received was used as the basis for negotiations in the purchase.  Bruce's estimate of $12,000 to $15,000 for repairs were added to certain other repair costs.  Ultimately, the Seller offered to discount the selling price by $18,000 which was slightly short of the figure we proposed.  In the meantime, we decided to look elsewhere.  So the house was never actually purchased. <br /> But I could not have asked for better negotiation support than we received from Bruce Ensor.  Had we purchased the home, Bruce's firm could have written specs on the problem that would have been given to the contractors bidding and otherwise have assisted with the solution.  <strong><em>We are well pleased with the services received, money well spent.</em></strong>  Thank you Bruce. <br />"

"Luyi from Louis & Associates is a professional engineer who knows the code and knows the calculations--and best of all, he's not one of those sales people that other companies send out.  He had no fancy equipment, just a level, measuring tape and vast knowledge of structures.  He was so nice and explained what he was looking for and what he did and didn't find.  And best of all, he determined that my house doesn't need repair work, but I would have trusted him if it did.  I will recommend Louis & Associates to anyone needing a structural inspection or design work. <br />"

"Our rating overall would be B+/A-. We love the final product of both the basement & deck with a gazebo; the craftsmanship was excellent. The workers were courteous and industrious & arrived, for the most part, on schedule. They did a good job of keeping the work area free of debris. Though the basic design/layout of the basement was done in advance, as the project progressed changes were made as we & the designer made suggestions. However, some of the additions such as crown molding and shelving along the stair wall could have been suggested in the original drawings. We chose engineered hardwood for the flooring which looked really great upon initial installation. Further inspection a few days later revealed hardened glue residue, which by that time was difficult to remove. Workers made several attempts to remove the glue with not much success. Given the unsuccessful repeated attempts and being weary of workmen disrupting everyday activities, we took on the job ourselves. The basement work started the first week of December 2018 and was projected to take 8 weeks; it passed final inspection in July 2019. The deck was started around 20 May 2019 and passed final inspection on 9 August. This was because of some code issues and inclement weather. The cost for the basement and deck with a gazebo was between $100,00 -$120,00, which was neither the highest nor lowest out of approximately five bids. All in all, we are very satisfied with the outcome and would recommend their services."

"We needed a structural engineer to inspect the foundation of a home that we are purchasing and were recommended to contact Kemp. We are so glad that we did. Greg provided first class service. He was thorough and took the time to explain each step that he was taking, the purpose behind it, the potential results and what each could mean, and finally the actual results. He also took the time to educate us on some of the basic indicators of good and deficient or damaged home foundations. He was very personable and is great at making complex information simple enough for novices to understand. He also provided the inspection report almost immediately. We highly recommend Greg and his company’s services."

"The whole experience, from sales rep, pre construction, installation and follow up was very professional yet personable. Communication was over the top. The warranty on material and labor is top notch. I will post pictures when I have good weather to take some. Here are the photos. The only reason for this storm door was to let light in. Our front door was hand built by a craftsman from Canada. It is 40”x 84” and 2.25” thick. Originally it was in a 2 x6 wall. In this installation the walls are 2x 4. The door hardware made it necessary for me to pad out all the exterior casing and sill nosing to accommodate the storm door. Thompson Creek provided me with a qualified installer to work with and he confirmed that adding an additional 3/4” thickness to my casing would allow their door to fit. I highly recommend this company."

"<p>Mr. Rahnama was extremely responsive. He accommodated my request for a Saturday appointment so I could be at home when he came out. He was very punctual...came right on time. He listened to what I needed and what my goal was. He performed a very thorough investigation of my existing deck. He made several recommendations to enhance the structural integrity of the deck and in a few instances weighed options and recommended to least costly approach. His report was thorough and was sent quickly.</p> <p>I am very glad I called Mr. Rahnama and feel confident as I proceed to discuss my deck replacement project with contractors.</p> <p> </p> <br />"

"Tom responded promptly to my inquiry through Angie's List. He is a a structural "Professional Engineer" and also a member of the NSPE. They are of the highest caliber. Although I went with the contractor's PE, Tom was very easy to deal with and honest about pricing and how he works on assessing matters for insurance agencies. If I had another need for a structural engineer, I wouldn't hesitate to call him back."

FAQs for engineer structural projects in Ashburn, VA

To determine if a wall is load-bearing, start by checking your home’s original plans or asking a structural engineer. Exterior walls always carry weight, but interior ones only do if they sit over a beam or run perpendicular to floor joists. If a wall lines up with posts in the basement or falls directly under the roof ridge, assume it’s load-bearing and call a professional before attempting to remove it with a sledgehammer.

Calculating the wall load and sizing the beam must be performed by experts to ensure structural safety. You need a structural engineer to evaluate all load aspects and determine the proper beam dimensions. A professional engineer performs precise calculations and advises on any necessary enhancements, such as larger footings for support. An inspector then verifies that the revised structure meets all safety and code regulations before the finishing work begins.

Hiring a structural engineer is essential for ensuring your home remains structurally sound during any major renovation. Their responsibility is to deliver expert assessments and design recommendations for load-bearing modifications. The average cost to hire a structural engineer is $500, with rates ranging from $350 to $800. Consulting a licensed, experienced engineer guarantees that every structural project, whether constructing a new home or remodeling an existing one, is completed safely and efficiently.

Almost all load-bearing wall removals require a permit as they support everything above it, and building departments want proof that the new beam can handle the weight. Pulling a permit triggers plan review and inspections that confirm the work meets local code and safety standards. Skipping this step can lead to fines or being forced to rebuild later, so have your contractor pull the permit before work starts.

Removing a load-bearing wall to create an entrance for a carport or covered patio is a task that comes with defined cost implications. This modification requires extra structural adjustments to ensure safety and proper integration with the adjoining space. When you convert a wall into an entryway, you can expect to pay between $3,200 and $9,500, with an average cost of $6,400. The additional work required for this conversion reinforces the home’s integrity and ensures compliance with applicable building codes.
