Hiring a hardscaping contractor is one of the most important steps in creating a durable, attractive outdoor space. In Delaware, with its coastal influence, freeze-thaw cycles, and varied soils, the right questions can mean the difference between a patio that lasts decades and one that needs repairs after a single winter. This article provides a comprehensive checklist of practical questions and considerations to help you hire a reliable contractor and get a hardscape project that meets your budget, schedule, and performance expectations.
A hardscape interacts with soil, water, and climate. Poorly designed or installed patios, retaining walls, driveways, and walkways can settle, crack, or drain poorly. Asking clear, technical and contractual questions up front protects your investment, clarifies expectations, and reduces the risk of disputes. You will also be able to compare bids more objectively when each contractor answers the same core set of questions.
Before you discuss design or price, verify basic credentials and protections. Credentials show competence; insurance and documentation protect you from liability and financial exposure.
Ask contractors to provide copies of insurance certificates and license numbers. Call the insurer to confirm policies are active and that the policy limits are adequate for the size of the job. If the contractor uses subcontractors, ask whether those subs are named on the certificate or whether the contractor accepts responsibility for them.
Experience matters more than smooth sales pitches. Look for demonstrated work on projects similar in scale and materials to yours.
When you speak with references, ask whether the job was completed on schedule, how well the contractor communicated, and whether any problems arose after completion and how they were handled. If possible, visit past projects to inspect workmanship in person — look at jointing, level and slope, edge restraint, and how the hardscape connects to existing structures.
The longevity of a hardscape depends on the right materials and the correct installation methods. A low bid that cuts corners on base preparation often costs more in repairs later.
A competent contractor should be able to explain why they choose a specific base depth (often 4-12 inches of compacted crushed stone depending on load and soil), how they compact materials (plate compactor, number of passes), and how they handle subgrade stabilization. Ask for trade-offs: cheaper options, life expectancy, and maintenance needs.
Hardscapes must move water away from buildings and not create ponding or seepage. Design and grading are as critical as materials.
Ask for elevation changes in writing; small slopes matter (a 1-2% slope is common for patios to drain away). For properties with tight yards or poor natural drainage, ask about stormwater solutions that comply with local codes and will avoid moving runoff problems to neighbors.
Permitting requirements vary by municipality, county, and the scale of the job. Permits may be required for retaining walls over a certain height, impervious surface increases, or structural changes adjacent to the house.
Verify that the contractor is familiar with the permitting process in your Delaware jurisdiction and will obtain necessary approvals. If the contractor insists you should pull permits, ask why and be cautious — hiring a contractor who manages the permit process reduces the chance of misstep.
Weather, material deliveries, and other projects can affect a schedule. A clear timeline reduces frustration and helps you plan.
Get the schedule and milestones in writing. Ask about contingency plans for delay and how change orders will be handled and priced.
A written contract protects both parties. It should be explicit about scope, materials, responsibilities, and remedies.
Avoid large upfront payments. Typical deposits range from 10% to 30% depending on project size and material costs; final payment should be withheld until you are satisfied and any required inspections are passed. Require lien waivers from the contractor and major suppliers at project completion to avoid later claims on your property.
Ask about both workmanship warranty and material warranties. Some materials carry manufacturer warranties; workmanship warranties are provided by the contractor and vary in length.
Document the expected care regimen: resealing intervals for pavers, how to clean polymeric sand, how to handle de-icing salts in winter, and vegetation control for joints.
Large projects often use subcontractors for excavation, masonry, or landscape lighting. Know who will be on site and who is responsible for final quality.
Clarity on supervision avoids finger-pointing later. Make sure the contract names the supervising project manager and provides contact details.
Low price alone is not a reliable indicator of value. Compare bids on apples-to-apples bases: same materials, base depths, drainage solutions, and warranties.
Be wary of very low bids that skimp on base, drainage, or edge restraint. Ask contractors to explain differences between their proposal and others you have received.
If you encounter these issues, keep looking. A professional contractor should be transparent, documented, and willing to explain technical choices in plain language.
Do your homework: verify insurance, see completed projects, compare detailed written proposals, and get everything in a signed contract. Value good site preparation and drainage as much as the surface material. Ask technical questions about base depth, compaction, edge restraints, frost protection, and drainage — competent contractors will answer confidently and in detail. Protect yourself with reasonable deposit limits, milestone payments, lien waivers, and a clear warranty. With these questions and precautions, you can hire a Delaware hardscaping contractor who delivers a durable, attractive hardscape that increases the enjoyment and value of your property.
