These days, I get to work with a great team and some amazing clients all across Utah County. We build decks, pergolas, walkways, and anything else that helps make a yard feel like home.

Frequently Asked Questions

The cost to build a deck in Utah varies based on materials, size, and design complexity. On average, homeowners can expect to pay between $15 and $35 per square foot for a basic deck using pressure-treated wood. Upgrading to composite materials can increase the cost to between $20 and $50 per square foot. Additional features like stairs, railings, and custom designs will also affect the overall price. Contact us today for a personalized quote.

Utah’s climate, with its hot summers and snowy winters, demands decking materials that can withstand temperature fluctuations and moisture. Composite decking is a popular choice due to its resistance to warping, rotting, and insect damage. Aluminum decking is another durable option, offering strength, low maintenance, and resistance to rust. Both materials provide longevity and require less upkeep compared to traditional wood. Not sure which material is right for your yard? Let’s talk through the best options for your climate.

A pergola enhances outdoor living by providing a defined space for relaxation and entertainment. It offers partial shade, making outdoor areas more comfortable during sunny days. Additionally, pergolas can increase property value, support climbing plants, and serve as a stylish architectural feature that complements your home’s design. Thinking about adding a pergola? Reach out and we’ll help you design one that fits your space and style.
