About This Service
Professional Pergola Staining & Sealing in San Diego County
Your pergola is the centerpiece of your outdoor living space — but San Diego's intense UV rays and occasional rain can turn beautiful wood gray, cracked, and weathered in just a few years without proper protection.
Pergolas face unique challenges compared to fences and decks. They're fully exposed to direct overhead sun with no shade, meaning UV damage is accelerated. The horizontal surfaces collect water during rain, and the complex joinery creates moisture traps that can lead to rot if left unprotected.
At Tom Sawyer Fence Painting, we specialize in pergola staining and sealing that protects your investment while enhancing the natural beauty of the wood. We use premium semi-transparent and solid stains with built-in UV blockers and waterproofing agents — the same professional-grade products we trust on hundreds of fences and decks across San Diego County.
Whether your pergola is brand new and needs its first protective coat, or it's been weathered by years of San Diego sun and needs restoration, our team has the experience and equipment to deliver a beautiful, long-lasting finish. We stain pergolas, arbors, patio covers, trellises, and all outdoor wood structures.
What's Included
Our Process
Inspection & Assessment
We evaluate your pergola's wood condition, checking for graying, cracking, mold, or rot. We recommend the right stain type and color based on your wood species and desired look.
Cleaning & Prep
We pressure wash or hand-clean the pergola to remove dirt, mildew, and old finish. For weathered wood, we apply a brightener to restore the natural wood tone before staining.
Stain Application
Using a combination of brush, roller, and spray techniques suited to your pergola's design, we apply premium stain with UV blockers and waterproofing agents for maximum protection.
Final Inspection
We inspect every beam, rafter, and joint for complete coverage. We ensure all end-grain cuts and joinery points are sealed — these are the most vulnerable areas for moisture intrusion.
Frequently Asked Questions
How often should a pergola be re-stained in San Diego?
In San Diego's climate, we recommend re-staining every 2–4 years depending on sun exposure. South-facing pergolas with no shade may need attention every 2 years, while partially shaded structures can go 3–4 years.
What stain do you recommend for pergolas?
We typically recommend semi-transparent stains with UV blockers for pergolas. They let the wood grain show through while providing excellent UV and moisture protection. For heavily weathered wood, a solid stain may be better to cover imperfections.
Can you stain a brand new pergola?
Yes — in fact, we recommend staining new pergolas within 30–60 days of installation. New wood needs time to dry and open its pores, but shouldn't be left unprotected for too long in San Diego's sun.
Do you stain the underside of the pergola too?
Yes, we stain all surfaces including the underside of beams and rafters. The underside is what you see most when sitting under your pergola, and it also needs protection from moisture that can wick up from below.
How much does pergola staining cost?
Pergola staining typically ranges from $500–$2,000 depending on size, height, complexity, and condition. A standard 10×12 pergola in good condition is usually $600–$900. We provide free estimates with exact pricing.
