All Pro Thornton Deck Builders
We're All Pro Thornton Deck Builders, a locally owned deck and outdoor living company based in Thornton, Colorado, building custom outdoor spaces since 2012. We design, install, repair, and replace decks of every kind, from straightforward ground-level platforms to multi-level, curved, and wrap-around builds, rooftop decks engineered for Colorado snow loads, and freestanding floating decks for tricky grades. Beyond decks, we build patios, porches, and pergolas, and we handle full pool deck installation, repair, and restoration. If you want to make the most of Colorado's sunny days, we also create outdoor kitchens, BBQ stations, fire pits, shade structures, and outdoor dining and media areas. We work with pressure-treated wood, cedar, and capped composite products like Trex and TimberTech, and we help you choose the right material for your budget and our Front Range climate. We serve homeowners in Thornton, Denver, Aurora, Arvada, Westminster, Broomfield, Northglenn, Brighton, Commerce City, and surrounding communities across Adams and Weld counties. The same crew handles your project from quote to completion, and we manage the full City of Thornton permitting process so you don't have to visit the building department. What we're known for is a straightforward process. Your written quote is your final price, with no change orders unless you request them and no surprises mid-project. We walk the finished project with you and we're not done until every detail meets your expectations. With a 4.8-star rating on Google, we'd be glad to talk through your project and provide a free, no-obligation estimate.

FAQs
What areas do you serve?
We're based in Thornton, Colorado and serve homeowners across the Denver metro, including Denver, Aurora, Arvada, Westminster, Broomfield, Northglenn, Brighton, Commerce City, Welby, Superior, Louisville, Lafayette, and Wheat Ridge, along with surrounding communities in Adams and Weld counties. The same crew works every city we serve.
What does pricing look like?
New deck installation typically starts from $8,000, patios from $5,000, pergolas from $5,000, and deck repairs from $500, with final cost depending on size, materials, and design complexity. We provide a free on-site estimate and a fixed-price written quote before any work begins, so you know the exact number upfront.
Do you handle the permits?
Yes. The City of Thornton requires a building permit for most new deck construction and significant structural repairs. We manage the full permitting process on your behalf, from application through final inspection, so you don't need to contact the building department yourself.
What decking materials do you use?
We work with pressure-treated wood, cedar, and capped composite products like Trex and TimberTech. For Colorado's climate, composite resists UV, hail, and freeze-thaw far better than natural wood. Trex carries a 25-year fade and stain warranty and Azek carries a 30-year warranty, while wood is a budget-friendly option that needs annual maintenance.
How long does a composite deck last in Colorado?
Composite decking like Trex Transcend typically lasts 25 to 30 years in Colorado's climate with minimal maintenance. It outperforms natural wood against the region's intense UV, hail, and hard freeze-thaw cycles.
What's your guarantee?
Your written quote is your final price, with no change orders unless you request them and no surprises mid-project. We walk the finished project with you at completion, and we're not done until every detail meets your expectations.
