Upper St. Clair landscaping built for wooded, sloped lots.

Q&A Landscaping has been completing high-end projects in Upper St. Clair since the start of the company. USC properties tend to be larger, with mature trees, sloped lots, and existing structure worth respecting, and that is what our crew builds for: retaining walls, patios, and plantings that work with the lot instead of fighting it.

Polished hardscape, drainage that holds.

Upper St. Clair properties tend to be larger, with mature trees, sloped lots, and existing structure worth respecting. Our work here ranges from exposed-aggregate patios to French drain installations, plus the outcropping walls and stone steps that make a sloped lot usable.

Rosetta Outcropping Walls, Exposed Aggregate Patio & Putting Green

We removed an existing patio and excavated further back to expand the usable backyard. Rosetta Outcropping walls and matching irregular steps lead up to a new putting green, finished with a generous exposed aggregate patio and full planting.

Frequently Asked Questions

Do you offer free estimates in Upper St. Clair?

+
Yes. Quinten walks every Upper St. Clair property himself before anything gets quoted or scheduled. Call, text, use the contact form, or book a time on Calendly.

What does a retaining wall cost in Upper St. Clair?

+
It depends on length, height, and how hard your slope is to access. Our retaining wall calculator turns those inputs into a realistic price range using our actual installed pricing in the South Hills, so you can run your numbers before we visit.

What does a paver patio cost here?

+
Patio pricing comes down to size and material choices. The paver patio calculator on this site uses our real installed pricing to give you a range in about a minute.

Do I need a permit for a wall or patio in Upper St. Clair?

+
Larger hardscape projects sometimes need a permit. We do not guess on this. We walk through what your specific project needs during the estimate, before anything gets scheduled.

Can you work on a steep or sloped yard?

+
Yes. Sloped lots with mature trees and existing structure worth respecting are common in Upper St. Clair, and that kind of property is most of what we build for. Retaining walls, outcropping walls, and drainage that actually holds are the core of our work here.

Which neighborhoods do you cover?

+
All of Upper St. Clair. We also work throughout the surrounding South Hills, including Peters Township, Bethel Park, Mt. Lebanon, South Park, and Canonsburg.

Are you licensed and insured?

+
Yes. Q&A Landscaping is a PA registered home improvement contractor (PA HIC #PA116241), fully insured, and a BBB Accredited Business with an A+ rating.

Do you take small jobs, or only big projects?

+
Both. The same crew that builds full outdoor living spaces also handles mulch refreshes, cleanups, and planting beds. Small jobs are how many of our long-term Upper St. Clair customers started with us.

Who will actually be at my property?

+
Quinten quotes every job personally, and the core crew has been together for years. You will not get a rotating cast of subcontractors.

What plants survive the deer around here?

+
Deer pressure in Upper St. Clair is real, and plant selection is half the battle. We recommend and install deer-resistant shrubs and perennials suited to your lot, and our deer-resistant plant guide on this site covers the choices we reach for most.

How does drainage work on a sloped USC lot?

+
Water has to go somewhere, and on a sloped lot with mature landscaping it usually needs help getting there. We grade and install French drains so water moves off the property instead of pooling against a wall or patio.

When should I book for spring or summer work?

+
Earlier than you think. The season runs early spring through winter and the calendar fills weeks ahead, so the best move is getting on the schedule before the season you want the work done.
