"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."

"Al came out quickly and gave me a bid. He offered an alternative material for the porch floor that would last longer than traditional wood at a reasonable cost and addressed my request to slighty slant the floor so that rain water would not sit on the floor's right side. Al came out and did the work himself. He did a very good job. The finish work was also nicely done. He pays attention to details. When I had concerns, Al addressed them and worked with me. Rain delayed the work on the back porch and painting, but he came back as the weather allowed and finished the work in a timely manner. Overall Al did a great job and I would hire him again."

"Chris and his crew made sure they knew my style and what I was looking for in my family room makeover. He built our mantle and shelves from scratch and we couldn't be happier with the way in turned out!!"

"Joe arrived right on time, asked what I wanted done, went to buy the materials, returned, and got right to work. Everything was installed quickly, neatly and professionally. He cleaned up everything and all the jobs he did look very nice! I will most likely compile another list in the future and use Freeman Custom Builders & Handyman again.
I purchased 8 hrs./$399.

"The timeline was the biggest problem.  The time it took contractor to finish the project was nearly 2.5 months from start to (almost) finish, with a single bathroom in the house. During this time, there were 2 holidays (Christmas and New Year's) and some days of inclement weather which would have prevented anyone from traveling (~3 in all). However, there was one entire week that I was on travel and returned to find zero progress had been made in that amount of time.
The original estimate was $2,500 for labor only for the bathroom. There were additional items that surfaced throughout the renovation which added scope to the project that increased the labor to nearly $3,700. I provided all material for the project.
Contractor requested milestone payments in advance of work being completed, to include final payment, which was made with promise from Contractor that he would return to fix minor "nit-pick" items, which never did take place. I have had to perform those items myself.
Contractor would set tools in bathtub and on top of porcelain toilet, which resulted in scratches in both. In retrospect I would have requested him to place pads down.
Contractor also did not lay down anything to protect the floors in the house from outside elements that were brought in on his boots (snow/rain), and that was then mixed with debris and dust from  the construction. This made it extremely difficult to clean the floors.
Overall, the bathroom looks nice. When looking in detail, however, once can see where craftsmanship/attention to detail is lacking due to a rush to complete the project.

"It has been a pleasure to do business with Ahmed construction. They provide very fair price on bidding. The administrative project manager Mr Albert is a hard working guy. Him along with the Mr Judy did the decking and replaced some studs on an addition remodel project. I highly recommend Ahmed construction and I will hire them again for any future project"

"Loay Jabbar provided the information I needed quickly and clearly. I immediately signed up for full coverages for our two homes because of the discounts offered and because of the quality of service that Loay is saying and promising Choice Home Warranty provides to its customers. I have bad experiences with other home warranty companies so I am hoping I found the best company that would deliver the best service."

Custom Home Builders FAQs, answered by experts

Construction typically takes 3-6 months, including site preparation and assembly.

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

How long it takes to build a custom home or rebuild a home after a disaster varies depending on many factors, but averages between seven and 14 months. Smaller homes or homes that don’t need a re-poured foundation may take less time to build than larger homes or homes without an existing foundation. Material availability, contractor schedules, and permit and inspection timelines can all affect how long your house takes to build.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.
