Deck Building FAQs
Get answers to common questions about our deck building services.
How long does it take to build a deck?
Most residential deck projects are completed within 1-2 weeks, depending on size and complexity. Simple decks may take as little as 3-5 days, while multi-level decks with custom features can take 2-3 weeks. We'll provide a detailed timeline during your free consultation.
What's the difference between composite and wood decking?
Composite decking (like Trex and TimberTech) is made from recycled materials and requires minimal maintenance—no staining, sealing, or sanding. Wood decking is more affordable upfront but requires regular maintenance. Composite decks typically last 25-30 years with warranties, while wood decks need replacement every 10-15 years.
Do I need a permit for a new deck?
Yes, most municipalities in PA and DE require permits for new deck construction. We handle all permit applications and inspections as part of our service, so you don't have to worry about the paperwork.
How much does a new deck cost?
Deck costs vary based on size, materials, and features. Pressure-treated wood decks typically start around $25-35 per square foot, while composite decks range from $45-70 per square foot. We provide free, detailed estimates so you know exactly what to expect.
Can you add features like pergolas or built-in seating?
Absolutely! We specialize in custom deck designs including pergolas, built-in benches, planter boxes, lighting, cable railings, and more. Our team will work with you to create the perfect outdoor living space for your home.
What maintenance does a composite deck require?
Composite decks are very low maintenance. Simply sweep regularly and clean with soap and water a few times per year. Unlike wood, composite doesn't need staining, sealing, or sanding. Most quality composite decking comes with 25-30 year warranties.
