We specialize in concrete services, repairs, pouring, leveling, driveways, walkways, patios, retaining walls and more. We pride ourselves on the quality work we provide, while delivering great customer service! Check out all the services we offer below and call -or- click to schedule a free estimate today!

"Very, very pleased with Ike & his team! First, he was very accommodating to my work-travel schedule by coming out to survey the project on a Sunday. Second, pricing was great. I got 3 quotes. Ike's was the middle one, but still much closer to the lowest quote. Third, his team is great. They showed up early & prepared. Very communicative about & effective in reaching their daily goals. Fourth, no surprise change orders or extra fees. It was a small project, but I'm very happy it ended on time & budget! Now, I did expect perhaps a little more rock base under the concrete & tighter rebar grid, but I'm no expert. Also not sure of what grade concrete was used, so I'm going by faith that Ike ordered the correct one for this driveway application. Time will tell the ultimate quality of this job. Also, a little coaching on what to do post-job would be helpful. Like "moist curing," full curing schedule, paint/sealant options after full curing. So, caveat emptor. Do your own due diligence & research. Overall, I would definitely recommend & use Ike's Construction again!"

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."
