Serrato's did an outstanding job. The bid was $1000 less than closest competitor, the timeline for fabrication was much faster (10 days vs 1-2 months), and the dimensions of the staircase matched the previous wooden installation (other bidders advised they would be narrower), with modifications to make sure everything was up to code. Work began immediately after we signed the contract and made a down payment for the job. I was given the choice between concrete and metal steps and landing. All steel were primered and painted, also all spot-welds were sanded, primered and painted. The stairs were installed within 10 days. Installation was delayed by 2 days, but Fernando (the owner of the company) called to explain that an issue at another worksite prevented him from starting. Once the work was underway it was completed efficiently. The quality of the workmanship was first-rate. I would give the highest recommendation to Serrato's.
