"Concrete by Design did a terrific job on our backyard patio extension and meandering pathway. They made good suggestions for improvements to what we planned and worked with our design requirements. Our lot had a few challenges when it came to installing additional hardscape, but those aspects did not stop them from doing a clean, professional job on our work. I highly recommend them and plan to use them again for future projects. Worth every penny we spent for a beautiful result!"

"Working with Esau was truly a great experience. He was communicative and available to answer all of our questions and he and his crew did the job with speed and efficiency. I donâ t know if we could have found anyone else on such short notice to do as close to good of a job as they did on our back yard leveling project. I highly recommend him and his team; amazing work for a good price."

"Elias Contruction provided a detailed estimate after inspecting the roof and making some qualified recommendations. The project required a few change orders that were not clarified in writing. I would recommend hiring Elias if you get changes in writing. They cleaned up pretty well although they missed a few things due to finishing in the dark. Overall satisfied with the job and cost was 60% of other bids due to sheathing adjustment."

"Schyler arrived at the appointed time explained the the process and how the equipment worked. After he finished he walked me through the completed work. He had cleaned up all the leftover residue explaining if there was any further movement in the work there was a five year warranty and he would return to correct it at no additional cost."

Foundation or Basement - Waterproofing, Inspection - Waterproofing
"We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that though ;)"
