"We cannot say enough good things about the help and care Ernest Vigil gave us from the start of our crawl space project to the end. He returned our calls and emails promptly and helped guide us each step of the way. He went above and beyond when a problem arouse to find local help to quickly come out to help address and fix the problem. Mathew from Puget Sound Water Rescue one of the local company is a good company to have on call. And your team members from Georgia were outstanding. We have several neighbors who have watched the care and quality we received with ground works and have said they will be the first company they will call when they are ready to have work done on their homes. Thank you, Ernest and the rest of your team for treating us like you would a member of your own family. It has been a pleasure working with you. Cindy and Alan D."

"Elias Contruction provided a detailed estimate after inspecting the roof and making some qualified recommendations. The project required a few change orders that were not clarified in writing. I would recommend hiring Elias if you get changes in writing. They cleaned up pretty well although they missed a few things due to finishing in the dark. Overall satisfied with the job and cost was 60% of other bids due to sheathing adjustment."

Patios questions, answered by experts

Stone steps are often more expensive than concrete steps as they are specially cut and installed, on top of the material costs. Concrete is more readily available as many steps are precast, although custom-poured concrete steps are an option more similar in price to stone steps.

No, high labor costs and the project's complexity make concrete stairs more expensive than steel or wood stairs. Wood steps cost between $100 and $200 per step, including labor and materials, while concrete steps are about triple, at between $200 and $600 per step. Building codes may also have stricter requirements for concrete steps, as they’re considered permanent, so you might also pay more for permits.

No, a deck is more expensive than a concrete patio. The cost to build a deck is between $4,200 and $11,700, or about $7,900 on average. This makes the average deck cost roughly twice as much as the average cost to build a concrete patio. Concrete patios also have far greater longevity and are easier to maintain.

With proper maintenance, exterior concrete steps can last 25 to 50 years or more. In most cases, your steps will require some minor repairs over that time frame, including sealing surface cracks and resurfacing to keep them in good condition. Interior concrete steps should last even longer, normally between 50 and 75 years, as they don’t have to stand up to the elements.

The cost to pour a driveway apron depends on the material and size. Concrete costs $3 to $10 per square foot, asphalt ranges from $2 to $5, and pavers are $5 to $15 per square foot. Additional expenses, like excavation, base material, and labor, can increase the total cost. For example, a standard 12x15-foot concrete apron could cost between $540 and $1,800, depending on local rates and additional work required. Always consult a local driveway paving contractor to get an accurate estimate tailored to your project.
