Services
We create outdoor living spaces that invite all season use. From Italian outdoor kitchens to Rocky Mountain fireplaces, PETRO Design/Build is positioned to handle any project you can dream of for your outside use while keeping the ecology of the site in mind. We provide value-added solutions for drainage and erosion along with sustainable and ecological landscape solutions.
Just as you would plan and organize your interior spaces for ease of movement and function, your exterior plan should include the organizational elements necessary to keep a potential hobby from becoming a chore.
Consideration of existing architectural elements when planning and designing outdoor areas is critical to achieving balance and harmony of the site. Don't let your landscape look like an afterthought.
Trying to stop or redirect water by building structures is not a lasting solution and will typically just move the water to another location with added force; think Grand Canyon. Where the ground is loose or unstable due to soil type, shade, tree roots, etc.; knowing exactly what you are dealing with and what will work for your particular situation is where Stormwater Professional's proven solutions can keep your site stable, save your trees and shrubs and protect your watershed.

Kathleen is knowledgeable, highly professional and has a good artistic sensibility. Great to work with and well worth the investment.

This is a great company to work with. We had major drainage issues in our back and side yards (standing water for weeks on end.) We got three estimates and felt Petro did the best job of scoping out the issues. For example, Kathleen was the only one who asked to look inside the house to check for dampness and mold. And their estimate was reasonable (the middle of the three in terms of cost.) Petro made some initial recommendations but once work began, they revised their recommendations, which resulted in a much better solution.

In some instances, the cost went up; in others, the cost went down. However, in no way did I feel like they were padding the cost. It was all about what the yard really needed. I found Kathleen and the project crew committed to an excellent job done, professional in their work, and able to hear and answer our concerns and questions. They were careful in doing the job and made sure everything was cleaned up before they left. I would have them come back in a heartbeat.

100% professional, and they know what they are doing. Don't usually write reviews but had to. This is a 1st rate business. I wish all the contractors I use were in this caliber.

Kathleen did a spectacular job designing and installing a solution for our stormwater issues. We used to get water in our basement and a lake on the sidewalk out front - my driveway was never dry causing algae to grow on it. This is no longer a problem and I am very happy with everything from start to finish. Very professional and trustworthy!

This is related just to the stormwater side of things, but we'll return to them when the time comes for a landscaping redesign. This is the second time we've done work with Petro, and both times we've been thrilled. Both of our jobs have probably been fairly small for Petro. Even then, Kathleen and Petro have made us feel like we were important customers, and took the time to explain everything in detail. Kathleen took the time to survey the house and look carefully at what was going on.

She explained exactly what was happening, and what our different options were, even if it meant less revenue for her business. Her proposals and contracts were easy to read and we understood exactly what was going to go on. Scheduling was a breeze, even during busy season. Work was professional and well done. Each time we've worked with them, they've gone above and beyond.

Their solutions helped us protect our house, and Kathleen and her staff always treated us like bigger customers. Can't say I want to do more stormwater work, but I know who we'll go to if we do. If only all of our home contractors were this responsive, good at their jobs, and helpful.

We contracted with Petro to improve drainage away from our house. This entailed substantial soil amendments at the rear of the house and improved drainage from multiple downspouts. The majority of the work was conducted under a low deck, a difficult environment to say the least. The crew was hardworking and professional. we couldn't be more pleased with the results.

Wonderful work. They helped replace a broken sump-pump, completely regraded our yard to help from water leakage in the basement, and did a lot of other amazing, detail-oriented work to solve water issues.
