What does a free estimate include?
Our free estimate includes an on-site property visit, professional measurements, and a detailed written estimate with line-item pricing. Every project also includes a 3D design preview — the design cost is fully credited towards your final build once your contract is signed.
How much does a patio cost?
Patio costs range from $18-35 per square foot depending on materials. A typical 300 sq ft patio costs between $5,400 and $10,500. We provide exact pricing during your free consultation.
How much does an outdoor kitchen cost?
Outdoor kitchens typically range from $15,000 to $50,000+. A basic grill island starts around $8,000-$15,000. The final cost depends on appliances, materials, and features.
How much does a retaining wall cost?
Retaining walls cost $25-$75 per square face foot. A 50ft long, 3ft tall wall would cost approximately $3,750-$11,250 depending on material and site conditions.
Do you offer payment plans?
Yes, we typically structure payments as a deposit, progress payments during construction, and a final payment upon completion. Financing options are also available.
How does the 3D design process work?
After our initial consultation and site measurements, we create a realistic 3D render of your project. You can see exactly what your space will look like and make changes at the design stage before construction begins.
How long does a typical project take?
Timelines vary by project: patios take 3-7 days, retaining walls 2-5 days, and outdoor kitchens 2-4 weeks. We provide a detailed timeline during the planning phase.
Do I need a permit?
Ground-level patios typically don't require permits. Walls over 4 feet, projects involving electrical or plumbing, and properties in flood zones may need permits. We handle the permit process for you.
What happens if it rains during my project?
Light rain doesn't stop most work, but heavy rain may cause a temporary pause. We communicate immediately about any weather delays and adjust the schedule accordingly.
Can I make changes during construction?
Minor adjustments can usually be accommodated. Major changes will be discussed with you regarding any impact on cost and timeline before proceeding.
What paver brands do you use?
We work with premium brands including Cambridge Pavers, Techo-Bloc, Belgard, and EP Henry. We also install natural stone options like bluestone, flagstone, and travertine.
Are pavers better than stamped concrete?
For Pennsylvania weather, we recommend pavers. They handle freeze-thaw cycles better than stamped concrete, are easier to repair, and typically last longer. Paver joints allow for natural expansion and contraction.
What materials work best in PA weather?
Interlocking concrete pavers and natural stone perform best in PA's freeze-thaw climate. The key is proper base installation — a well-prepared base matters more than the material itself.
How long do pavers last?
With proper base preparation, pavers can last 25-50+ years. Quality interlocking pavers are rated to withstand thousands of freeze-thaw cycles.
