"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."

"Wanted to fix the problem caused by large Pine and Magnolia Tree leaves continually clogging gutters causing periodic water damage. Decided to install good quality Gutter Guards and fix the current water damage.
Al kept me informed at least a day in advance of his schedule and arrived when promised which I appreciated.
Below are some of the task I watch Al and his brother do and was very happy with the quality I saw.
Gutter Guards
Pressure washer cleaned gutter, downspouts, and surrounding area.
Removed gutters and installed metal protection on fascia board where needed
Adjusted gutter angle to make sure water drained correctly on all sides
Installed and screwed in Guards on all the Gutters to keep in place
Added Metal End caps to prevent squirrels and bird access to gutters.
Corrected a Gutter Problem that caused leaves and debris to collect and build up at one section of the roof allowing water to
flow over sides.
  Back Exterior Jalousie Door Replace
Bought Solid Core Door and cut to exact size of
old door
Cut out center for the Jalousie windows from the
old door
Primed (Weather Proofed) door on all external
surfaces
Installed the Jalousie Windows from old door
Set Door in place and adjusted for perfect fit
Installed new Aluminum Door Sweep and adjusted
for fit.
Installed and tested new electronic lock
60x56 Jalousie Window Frame Repair
Removed Rotting wood at base and along sides
Installed new wood along sides and Vinyl Composite
Simulated Lumber at the base for water resistance.
Caulked all access points around the frame.
Install New Storm window
Removed old storm Window frame from Kitchen
Window
Installed new Storm Window
Other
Cleaned area and left it looking better than
when they arrived
Sent Pictures of how the Gutter install looked
like from above the roof.
Alerted to other problems (Chimney, Tuck
pointing) I did not know about.
Today is 1-July-2014 and three storms have come through since installation and I have seen none of the problems I had before the guards were installed. Normally I would be cleaning out the clogged down spouts!!

I was very happy with the results and consider the money well spent.

"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."

Custom Home Builders FAQs, answered by experts

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

A construction-to-permanent loan is the most common type of mortgage used to finance a house teardown and rebuild. These loans include financing for construction costs and convert to a long-term mortgage once construction is complete. Check the terms of the loan closely before beginning work—there are often restrictions requiring you to use licensed contractors for all work.

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.
