"From the beginning of my project in January 2024, I have never regretted my decision to choose Ethos Building Group LLc. Jeh Johnson and his partner Tracy Herod have worked diligently to execute the itemized proposal that began this project to rehab, restore, and rebuild my home at 607 Wilmington ave. St. Louis MO 63111. An incredible number of tradesmen and tradeswomen have done their individual tasks all on a schedule professionally overseen by Jeh. These liscensed and masters of their trades worked alongside Jeh who if necessary stepped in and aided e these individuals. His overall expertise has brought my home to this point. One must keep in mind that a burnout like my home is an unusal job for Ethos Buildig Group LLc to accept. Yet at every stage my home has been given the same careful and thorough attention as their larger jobs. And despite some push back with my insurance company every thing has proceeded smoothly and orderly manner given the inevitable supply chain delays. Jeh Johnson is an affable young man who has facilitated all phases my prject and has even taken time to educate me on all the intricacies involved in a project such as mine. I cannot think of any single word to describe my experience with Ethos Building Group LLc but the forgoing will have to suffice. Thanks you for your kind attention. Stay safe and make a point of telling those who you find dear just what they mean to you."

"We hired Homesource to build a kitchen/hearth room addition onto our house. They were wonderful to deal with and we are extremely pleased with the results. Their carpenters, project managers and production crew were true professionals. We were also impressed with the expertise and professionalism of all the sub-contractors that they hired. We would highly recommend Homesource to anyone looking to build a custom home or remodel an existing home."

"I had some loose metal that was very dangerous if it had broken off. Mr Freeman was near by and was able to come reattach the metal. It was really cold but that didn't stop him from reattaching the loose portions. I was really grateful for the emergency work."

"Our kitchen was ugly and barely working.   We went to Angie's List and hired Good Neighbors, LLC for a previous job and we hired them again and they gave us an outstanding kitchen remodel.
Good Neighbors had previously done a master bath remodel for us in 2012, which we love!  So when it came time to update and remodel our outdated 30 year old kitchen, we again hired Good Neighbors to do the kitchen remodel.  
They gave us a price, they gave us a finish date and they finished within budget and they finished on time.  Impressive!
Our kitchen was a complete demolish from the ceiling to the floor.  We installed new cabinets, new appliances, new lights, granite counter tops and updated the electrical service and the plumbing.   We did a lot. 
Our kitchen, as with many older home remodels came with several surprises once the work started.   However, Good Neighbors was able to handle the required fixes flawlessly and perfectly.  Most importantly, we are thrilled with the end result.  Even the building insectors complimented their work.
One point worth mentioning, which we really appreciated, was the fact that the Good Neighbors personnel, Tom, Chris and Caleb showed up on time, worked hard all day and cleaned up every night.  They never let us down, never left us hanging nor left us a mess to clean up.
The finished kitchen is even better than we had imangined.   Good Neighbors is worth of a glowing recommendation from us and we recommend them for any interior remodel and proudly give them an A."

It is a good idea to check in with your local city and state regulations before committing to building a shipping container home no matter where you live. This concept is pretty new across the country, and many places won’t let you build one.

The International Code Council (ICC) offers guidelines for home builders on the safe use of ISO intermodal shipping containers repurposed as building components, which can be helpful to review when planning or designing a shipping container home.

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.
