How Much Does It Cost to Stain a Deck? DIY vs Professional
A professional charges $1,000-3,000. DIY costs $150-400. Here is whether the savings are worth your weekend.
Professional deck staining costs $2-5 per square foot ($600-1,500 for a 300 sq ft deck). Includes power washing, sanding, repairs, stain application (2 coats), and cleanup. DIY costs: stain ($30-50/gallon, 2-3 gallons needed: $60-150), power washer rental ($50-75/day), brushes/rollers ($15-30), painter tape and supplies ($20-30). Total DIY: $150-400.
Is DIY Worth It?
A 300 sq ft deck takes a professional crew 4-6 hours. DIY takes 8-12 hours over 2 days (power wash day 1, let dry overnight, stain day 2). You save $500-1,100 but spend a full weekend doing physical labor in the sun. If your hourly rate at work is above $50/hour, hiring professionals is the better financial decision. If you enjoy the work or need to save money, DIY produces identical results if you follow the process correctly.
How Often to Stain
Semi-transparent stain: every 2-3 years. Solid stain: every 3-5 years. If you skip staining, the wood grays, splinters, and eventually rots — replacing boards costs $5-15 each versus $0.50-1 per square foot for stain. Regular staining extends deck life from 10-15 years (untreated) to 25-30 years (maintained). The $200-300 every 2-3 years prevents $5,000-10,000 in premature deck replacement.
