Durable and Stylish Decks That Fit Your Budget

Your deck should be a stylish, functional extension of your home—not a source of ongoing maintenance and repairs. Poor craftsmanship, weak materials, or high costs can leave you with an outdoor space that doesn’t meet your expectations.

At Alterra Landscaping, we build budget-friendly decks designed for long-term strength and beauty. Whether it’s an attached, front entrance, or backyard deck, our experienced team ensures expert craftsmanship and high-quality materials. With warrantied work and a commitment to precision, your deck is built to last.

“We highly recommend Alex at Alterra and will most certainly use his company for future landscaping needs.”

“We are thrilled with the work on our backyard. Alex and his team built a new expanded patio with lighting. The team was efficient and friendly. I am grateful for their extra attention and help moving plants and replacing a cracked stone from a previous contractor’s job. They worked hard each day and completed the job quickly and well. We highly recommend Alex at Alterra and will most certainly use his company for future landscaping needs. Thank you. 10/10”
