Free onsite estimate
We are a small business. We were established in 2012. Most of business is from word of mouth. We specialize in all line of concrete work, fencing, sodding and landscaping.
"Starting with the estimate (which was comparable to the other estimates I got), Gibran spent more time discussing exactly what I wanted and needed: the old walk was narrow, did I want it widened; squared off or rounded out where it met the garage slab; raising the back walk slightly to eliminate the extra, shallow step at each end; and most usefully, how to work around the 100 year old catalpa, that had lifted and broken the old walk, between it and the house. We ended up adding a curve to the walk, just by the tree, giving it extra space without disturbing the existing tulip bed on the other side of the walk along the house. He and his crew worked quickly and neatly, and did a very nice job. The new walks meet the city sidewalk and garage slab evenly, the curves are smooth, the tree has room, the tulip bed and ivy along the house weren’t disturbed, and now it’s much less of a pain to shovel snow than it used to be! As a bonus, landscaping was not part of the contract, but Gibran found a source of black dirt for us, and when there was a delay (while waiting for the city inspector) after the forms were in place, he and his crew spread the dirt needed to regrade the yard for us, rather than just sit around. I’m very pleased with the work they did for us, enjoyed working with Gibran and his crew, and would definitely recommend 5 Star Concrete & Construction."

Basement waterproofing and foundation repair company. Family operated since 1957 with over 500,000 dry basements. Free consultations. Lifetime warranties available. Award winning company.
"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"
