Our Services

Soil Testing

We take extra steps upfront to set your commercial foundation up for long-term stability and safety. Before finalizing any foundation plans, we complete thorough soils testing across the site. Soil testing is a crucial step in the permitting process for commercial construction projects. This provides key data like the composition of subsurface materials, load-bearing capacity, and depth to bedrock. Complying with the local building codes upfront mitigates risks associated with foundation failures and instability later.

Helical Piles & Helix Piers

Screw pile foundations are installed by twisting them into the ground to provide high load capacity support even in challenging soil conditions, such as loose or unstable ground. Smith & Son leverages helical piles as an effective foundation solution to minimize the risk of structural instability.

Tieback Anchoring

Earth anchors and tieback shoring walls reinforce retaining structures by gripping the soil to provide lateral resistance. The Smith & Son team designs and installs helical tieback anchoring systems to offer reliable support on commercial projects.

Sinking foundations are stabilized and lifted using hydraulic push pier systems pressed into the earth below the structure. Smith & Son performs foundation underpinning to rectify settlement issues and restore structural integrity to provide lasting solutions for clients facing these challenges.

Crawl Space Leveling

Adjustable steel jack systems are utilized within crawl spaces underneath beam floors to address uneven surfaces and settlement. Commercial crews properly install crawl space jacks to seamlessly level structures, enhancing safety and longevity.

I have several reasons for highly recommending Smith & Son Inc. Our project was the installation of a composite deck over a worn out cement patio. Out of the three quotes we received, Lance Smith not only provided us with a detailed quote quickly, he was the only who followed up to discuss his quote. This discussion clarified our project and saved on the overall cost, putting us within budget. Lance recommended a decking material which we are extremely pleased with. Knowing we were eager to start, Lance found a way to begin our project much sooner than expected. His three man crew was led by a seasoned and experienced foreman, Noe, who checked in with us frequently to make sure we were satisfied. Noe took great pride in his work and was very eager to please. We are very happy with the finished project which exceeded our expectations. We would not hesitate to use Smith & Son again!

As a Real Estate Director with a portfolio that contains both commercial and residential properties, I am always managing construction in some capacity. After using Smith & Son for one project, they have become our go-to contractor for any and all construction needs. They have completed at least 6 major projects for us (not counting minor alterations and repairs) and the work has all been impeccable with all details paid close attention to. In addition to the quality of the work done, Lance is fantastic to work with. He is responsive, proactive, and up-front. Every project has been completed on-time, and, when any issues have arisen Lance has communicated them clearly with a plan already in place to address them. He will provide multiple options for projects and recommendations as to how things could be done better, more efficient, and less costly. Everyone I have interacted with at Smith & Son has been equally as fantastic, whether working in their office or onsite at jobs. I cannot recommend Smith & Son highly enough; you will not be disappointed.

I hired Smith & Son to remodel the home office in our backyard. After getting quotes from several contractors, meeting with Lance was like a breath of fresh air -- he was clear, detail oriented, on top of everything, and took ownership over the project. He cares about quality and is not in the business of squeezing money out of customers -- I feel like he was giving the advice he would give to a friend.

I knew the project was in good hands with him and his team in charge. We had great/easy communication throughout, Lance stopped by to check in on the details, and his team was great. We are really happy with the result and I would hire Lance again in a heartbeat.

If you are deciding between contractors for your project, hire Smith & Son!
