Frequently asked questions
What is your typical process for working with a new customer?
When a new customer reaches out, we start by asking for a brief description of the work they need. We then schedule a site visit to provide a free, no-obligation quote. During the visit, we listen to the customer’s needs, discuss their specific goals, and offer practical solutions. We take accurate measurements and gather all the necessary details, then send a detailed quote within 1–2 business days.
What education and/or training do you have that relates to your work?
Our crew has over 10 years of on-the-job training and hands-on field experience. We’ve mastered our craft by working directly in real project environments, ensuring quality workmanship and practical problem-solving skills.
Do you have a standard pricing system for your services? If so, please share the details here.
Yes, we price our services by the job. Every project is unique, so we provide custom quotes based on the scope of work, materials, and labor required. All quotes are detailed and transparent so customers know exactly what they’re paying for.
How did you get started in this business?
After years of working for a concrete company, we began taking on side projects for friends and local clients. The demand for our work quickly grew, and we decided to officially transition into a licensed, insured company. With over 18 years of field experience and three years in business, we’ve been proudly serving our community ever since.
What types of customers have you worked with?
We’ve worked with both residential and commercial clients, handling everything from home improvement projects to larger-scale construction jobs.
What advice would you give a customer looking to hire a pro in your area of expertise?
Always check that your contractor is licensed and insured. This protects you as the customer and ensures that the work is being done by qualified professionals who stand behind their craft.
What questions should customers think through before talking to pros about their needs?
Before contacting a contractor, it’s helpful to know your desired timeline, budget range, and any specific design or finish preferences. Having measurements or a clear idea of the space can also speed up the quoting process.
