"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."

"We hired Jose last summer (2025) to remove some flag stones in the back yard and move them to the front walkway as well as put in a 16x14' concrete slab in the back yard. We interviewed 4 other contractors but he was the only one that gave us ideas on how to make it better than I could have imagined! What originally started as a single concrete slab in the back yard turned into a show piece walkway in the front yard and a back yard patio that was nice enough to add a gazebo! You would think that with all the extra add ons it would have been way over budget but it ended up costing much less than all the other quotes! We are looking at having Jose put in a new 28'x28' slab in the other side of the yard for a possible basketball hoop or, gosh, anything. I really recommend this company. Jose is very personable, professional, and very very qualified. Thanks Again Jose!"

"David and Cody from John's Waterproofing went straight to work; they quickly found the problem, showed me the problem, discussed what would have to be done to fix the problem, fixed the problem, then thoroughly cleaned up. Very nice people to work with, from the schedulers through the technicians."

"I had a patio that was in need of leveling. They knew exactly what to do and did it in a day. It looks great and I am very happy."

"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 ;)"

"I would give Andrew highest marks in every catagory; communication, holding to his schedule, level of expertise and quality of work."

"It went wonderfully. Very studious and very polite to the point that he got everything on time. Very knowledgeable."
