"I'm shocked by all of these 5 star reviews, but then again, I shouldn't be considering they ask for a 5 star review BEFORE they do any work during the estimate phase. They dug up our rose bushes and just left them there to die. They left their clothes in our basement and didn't even bother to clean up after themselves. They also left one of their tripods on our backyard. Not to mention, my husband found 2 cracks from their work order that they didn't even attempt to seal. Oh, and the plates they put on the wall are all crooked. Fast forward 2 weeks and one of the plates is leaking. This is abysmal and I recommend you STAY CLEAR. All photos are of "finished" work."

"We absolutely love our new Ryan home, which is ready to move into. Jon, the construction manager was true to his word, and had the Home completed by the end of May. However., DO NOT GO WITH NVR MORTGAGE! We were supposed to close June 7, and Martha from NVR knew we wanted an early June close, I was retiring July 1st, and our mortgage was based on my pension MONTHS AGO. Now, a few weeks before closing after we scheduled a TON of services including movers, truck, friends taking off to help, babysitters for kids, and have a buffer of 3 weeks before we have to move out of a rental end of June; Martha tells me they require a certain letter from the pension that I will not receive until mid-july. Because of this they initially said we couldn't close until July. Then it is June 20th. If she provided us with this information months ago, we could have planned differently. Now we are scrambling to figure out what to do. So, I repeat, DO NO GO WITH NVR MORTGAGE. I'm not the only one either. I just spoke to our new neighbors who broke off with NVR and Martha after 6 months before closing because of similar issues. DO NOT GO WITH NVR MORTGAGE!!!! it should be NO STARS FOR NVR MORTGAGE."

FAQs for engineer structural projects in Gillespie, IL

The timeline for replacing a support beam varies based on several factors, including accessibility, length, and your home's specific structural requirements. The process involves multiple stages: planning, permitting, material procurement, and installation. Complications like discovering additional damage, electrical obstacles, or plumbing conflicts can extend the timeline. Consulting with contractors during the estimate process will give you a more accurate project duration for your specific situation.

Warning signs of a compromised support beam include noticeable floor sagging or bouncing, cracks appearing in walls (particularly near doorways), doors that suddenly stick or won't close properly, and visible damage to the beam itself. You might also notice unusual creaking sounds when walking across certain areas or gaps developing between walls and ceilings. Any of these symptoms warrants prompt inspection by a structural professional to determine whether repair or replacement is necessary.

In certain situations with limited damage, reinforcement techniques like sistering (attaching a new beam alongside the existing one) or adding steel plates can extend a beam's useful life. However, these approaches are only suitable for minor issues. Complete replacement is often necessary when significant deterioration affects more than half the beam or compromises its structural integrity. A structural engineer should evaluate the specific conditions to recommend the appropriate solution for your home.

Whether you need temporary housing during beam replacement depends on the beam's location and your project's scope. Many homeowners can remain in their homes during the work, particularly when the beam is in a basement or crawl space. The primary considerations are noise, dust, and access restrictions in the work area. If the project involves major demolition or affects critical living spaces, temporary relocation might be more comfortable. Discuss the project timeline and daily impact with your contractor before making this decision.

Support beams should be examined periodically as part of routine home maintenance. Pay particular attention to events that could affect structural elements, such as flooding, significant foundation movement, or pest infestations. If you notice any warning signs like sagging floors, wall cracks, or visible beam damage, arrange for a professional assessment immediately. Catching potential problems early can prevent more extensive damage and reduce repair costs.
