Schellhaas Landscape Construction Shares What Allegheny County Homeowners Should Look for in a Landscape Design-Build Contractor

A Pittsburgh-area landscape construction company offers guidance on contractor qualifications, project estimates, drainage planning, and the benefits of a coordinated design-build approach.

PITTSBURGH, PA — Choosing a landscape contractor involves more than comparing project prices or reviewing photographs of completed outdoor spaces. Schellhaas Landscape Construction, a Pittsburgh-area landscape design and construction company with more than 25 years of industry experience, encourages Allegheny County homeowners to consider contractor qualifications, construction methods, and project accountability before investing in patios, retaining walls, and custom outdoor living improvements.

Owner Mike Schellhaas says homeowners planning major landscape projects should understand what a contractor's proposal includes, who will oversee the work, and how the company plans to address site-specific conditions.

"There's a lot more to a successful outdoor project than choosing the right pavers or deciding where a patio should go," said Mike Schellhaas, owner of Schellhaas Landscape Construction. "Homeowners should feel comfortable asking questions about how the project will be designed, what goes into the construction process, and who will be responsible for the work from beginning to end."

Understanding the Landscape Design-Build Approach

A landscape design-build contractor coordinates the planning, design, and construction of an outdoor project through one company or an integrated project team. Instead of hiring separate providers to develop a landscape plan and complete the installation, homeowners work through a coordinated process that connects design to construction requirements.

This approach can be especially beneficial for projects that combine multiple outdoor features, such as paver patios, retaining walls, walkways, outdoor kitchens, fire pits, and landscape lighting.

When you consider these elements together, design decisions can account for grading, drainage, material selections, accessibility, and how different spaces connect.

Schellhaas Landscape Construction uses a residential design-build approach for landscape improvements and custom outdoor living projects in Allegheny County and surrounding Pittsburgh-area communities.

Questions Homeowners Should Ask During a Landscape Consultation

An initial consultation lets you evaluate more than the contractor's design ideas. Homeowners should ask questions that help clarify the proposed construction process and the company's responsibilities.

Important questions include:

• Who will develop the landscape design and manage construction?
• What site conditions could affect the project's design, budget, or timeline?
• How will drainage, excavation, and base preparation be addressed?
• What materials and installation methods are included in the estimate?
• Is the contractor properly insured, and can they provide documentation?
• What certifications, manufacturer credentials, warranties, and references are available?
• How does the contractor handle unexpected conditions, project changes, and additional costs?

Clear answers can help homeowners understand how a contractor approaches planning, communication, and long-term project performance.

Why Drainage and Base Preparation Matter in Western Pennsylvania

For homeowners in Allegheny County, evaluating a contractor's technical knowledge matters because of the region's varied terrain.

Sloped properties, elevation changes, soil conditions, and water movement can all influence the construction of patios, retaining walls, and other hardscape features.

A properly planned paver patio requires more than an attractive finished surface. Excavation depth, aggregate base materials, compaction, grading, and drainage must be evaluated based on the property's conditions and the intended use of the space.

Similarly, retaining wall construction may require careful consideration of soil pressure, drainage behind the wall, and the stability of surrounding areas.

Homeowners should ask prospective landscape contractors to explain how they'll address these elements rather than assuming they are included in every proposal.

"Two patios might look very similar when they're finished, but what's underneath them can be completely different," Schellhaas said. "Drainage, excavation, and base preparation are important parts of the project. Those are the details homeowners should ask about because they can affect how the finished space performs over time."

Comparing Landscape Construction Estimates Beyond Price

Price matters when selecting a landscape design-build contractor, but the lowest estimate may not reflect the same scope of work.

Homeowners comparing proposals should check whether contractors account for similar materials, site preparation, drainage solutions, excavation, base construction, cleanup, and other project requirements.

An estimate that provides limited construction details may leave important questions unanswered.

Potential warning signs include vague material descriptions, missing site-preparation information, unclear allowances, verbal promises not included in writing, and an inability to explain how changes will affect the final cost.

A detailed proposal makes it easier for homeowners to understand what theyare buying and compare contractors more consistently.

Contractor Credentials, Insurance and Warranties Deserve Attention

Before hiring a landscape construction company, homeowners should ask for appropriate proof of insurance, applicable licensing information, professional credentials, and references from comparable projects.

Manufacturer-authorized contractor programs and industry certifications can provide additional context about a company's training and experience. Homeowners should also ask whether warranties cover workmanship, materials, or both, and request the specific terms in writing.

The company also lists Techo-Bloc Techo-Pro, ICPI installer, and NCMA credentials in its published company information.

While credentials are useful, evaluate them alongside completed projects, construction practices, communication, and the contractor's ability to address the specific property.

The Value of One Accountable Project Team

Outdoor living projects often involve interconnected construction decisions. For example, a change in patio elevation may affect steps, retaining walls, walkways, drainage, and surrounding landscaping.

A coordinated design-build team can reduce communication gaps between planning and installation and make it easier to identify who is responsible for key project decisions.

For homeowners planning larger outdoor living spaces, knowing who will manage schedules, answer questions, and coordinate construction is an important part of selecting a contractor.

"When someone invests in their property, they should know who's responsible for the project and feel confident that the design and construction teams are working toward the same result," Schellhaas said. "Good communication and a clear plan are just as important as the materials being installed."
