Downingtown Engineering Consultants

My name is David A. Weightman, P.E. and I have 46 years of structural engineering experience. I specialize in designing openings in residential load bearing walls using dimensional lumber for short spans, engineered lumber for intermediate spans, and steel beams for long spans. Usually, this involves removing a load bearing wall between a kitchen and living or dining room. I also strengthen sagging floors, design repairs for cracked basement walls, and design retaining walls, decks, porches, and additions. You may use my drawings to obtain contractor bids and building permits. Once construction begins, I will inspect the work, if you desire. My clients include home owners and remodeling contractors. I will explain structural concepts to you in a clear, professional manner. Usually, I can complete the design within 10 calendar days or less. Saturday appointments are available. NOTE: Residential projects only!! NO industrial or commercial projects.

David Weightman is very knowledgeable and thorough. He spent the time reviewing our situation and provided a detailed solution during a time sensitive structural issue that will hopefully save the purchase of a home we are set to buy. Highly recommend David at DEC (Downingtown Engineering Consultants).

David Weightman responded quickly to my request. He was very pleasant and professional. While inspecting the wall I intended to remove, he was happy to answer any questions I had. He was very informative and easy to talk to. He offered great advice for a great price.

DEC went above and beyond giving us information on our house and what to look for regarding our concerns and how to fix some small issues, not all related to what they were called into look for.

He was an expert and on time. But charged me more than he told at first.
Response by Downingtown Engineering Consultants: The builder installed a beam that was undersized. The previous owner installed a loose pile of blocks in the center. The client informed me he had to have the report done the day of my inspection due to next day closing. I included a footing design and concrete block pier design with cost estimate in addition to the agreed upon price of the report. This helped the client with closing cost negotiations. I added one extra hour of my time to accomplish this. Live and learn.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate.
