Questions? Answers.

Everything you need to know about patio covers in King & Snohomish County.

How much does a patio cover cost in the Seattle area?
Patio cover costs vary by material and size. Alumawood covers typically range from $10,000–$25,000, solid insulated covers from $12,000–$30,000, and premium motorized louvered pergolas from $15,000–$40,000+. We provide a detailed, transparent estimate during your free consultation so there are no surprises. Financing options are available.
Do I need a permit for a patio cover in King or Snohomish County?
Attached patio covers almost always require a building permit in both King and Snohomish County. Freestanding structures under certain size thresholds may be exempt. We handle the entire permit process for you — applications, structural engineering, and inspections — so you don't have to deal with any paperwork.
What's the difference between a patio cover and a pergola?
A patio cover is typically attached to your home and provides full shade and rain protection. A pergola has an open, slatted roof that provides partial shade. Today the terms are often used interchangeably. We offer both — from solid waterproof covers to open pergolas, plus hybrid options like louvered pergolas that adjust for sun or rain.
What is the best patio cover material for Seattle's rainy weather?
For maximum rain protection, we recommend solid insulated aluminum or alumawood covers. They're 100% waterproof, won't rot or warp like wood, and require virtually zero maintenance. For homeowners who want adjustable coverage, motorized louvered pergolas with rain sensors are the premium choice — they close automatically when rain is detected.
How long does installation take?
Most patio cover installations are completed in 1–3 days. The total timeline from consultation to completion is typically 3–6 weeks, including design, permitting, and material ordering. Your dedicated project manager will provide a detailed schedule before we begin.
Will a patio cover increase my home value?
Yes. A professionally installed patio cover can add $8,000–$18,000 in property value and increase your home's overall value by 8–10%. Well-designed outdoor living spaces consistently deliver 80%+ ROI, making a patio cover one of the best home improvements you can make.
What's the difference between alumawood and real wood?
Alumawood is aluminum with a realistic wood-grain finish. It looks like real wood but won't rot, warp, crack, or attract termites. It requires zero maintenance — just rinse it off occasionally. Real wood (cedar, pine) looks beautiful initially but requires regular staining and sealing, especially in the Pacific Northwest rain, and typically lasts 10–20 years vs. 25–30 years for alumawood.
How do I maintain my patio cover?
Alumawood and aluminum covers require minimal maintenance — occasional rinsing with water or mild detergent keeps them looking new. Wood pergolas need staining or sealing every 2–3 years in the Pacific Northwest. Louvered systems may need occasional lubrication of moving parts. We provide care instructions with every installation.
Can you cover an existing deck or patio?
Absolutely. We install patio covers over existing concrete patios, wood decks, composite decks, and pavers. We'll assess your existing structure during the free consultation to ensure proper support and a seamless integration with your home.
Do you offer financing options?
While we don't provide financing directly, we work with homeowners who use home equity loans, HELOCs, personal loans, and credit lines. We can also connect you with lenders experienced in home improvement financing to find the best option for your budget.
