"5++ stars! My home's exterior was cracking due to a poor job prior and drainage issues. Tom and Adam and the team not only gave me peace of mind moving forward with drainage, put in gutters, and re-did the entire exterior of my home (stained wood and stucco), but made it beyond beautiful!! They were communicative, timely, so easy to work with, and the end product is gorgeous. I would recommend them to anyone who needs a construction project done and can't wait to use them again on my next project!!"

Structural Engineering questions, answered by experts

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

You should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

Yes, unresolved damage can decrease property integrity and market value.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.
