Top Questions to Ask a Contractor Before They Stain Your Deck and Fence

Hiring a professional to stain your deck and fence can save you time, effort, and ensure a long-lasting finish. However, not all contractors are created equal, and choosing the right one can make all the difference in protecting your wood from the elements.

Before hiring a contractor, it’s essential to ask the right questions—especially when it comes to the type of stain they use. A non-film-forming oil-based stain is the best choice for long-term durability, preventing peeling and flaking while allowing the wood to breathe.

Here are the top questions to ask before signing a contract for deck and fence staining.

1. What Type of Stain Do You Use?

This is one of the most important questions to ask. Some contractors may use film-forming stains that create a surface layer, which can lead to peeling, cracking, and flaking over time. Instead, look for a contractor who uses a non-film-forming oil-based stain, which penetrates the wood and provides superior protection without trapping moisture.

✅ Best Answer: "We use a high-quality, non-film-forming oil-based stain that penetrates the wood for long-lasting protection and natural wear."

🚫 Red Flag Answer: "We use whatever stain you want, including solid stains and paints." (This suggests they may not specialize in using the best product for longevity.)

2. How Do You Prepare the Deck and Fence Before Staining?

Proper deck and fence preparation is key to ensuring the stain adheres correctly and lasts as long as possible. A professional contractor should perform:

• Deck washing to remove dirt, mold, and mildew

• Deck sanding (if needed) to smooth rough areas and remove old stain buildup

• Proper drying time before applying stain

✅ Best Answer: "We clean, sand (if necessary), and allow the wood to dry before staining to ensure maximum stain penetration."

🚫 Red Flag Answer: "We just power wash and stain the same day." (This may indicate they aren’t allowing the wood to dry properly, leading to poor adhesion.)

3. How Many Coats of Stain Will You Apply?

With a non-film-forming oil-based stain, only one flood coat is needed. The key is to apply as much stain as the wood can absorb—not more. Contractors who suggest multiple coats may not be experienced with penetrating stains, leading to an unnecessary buildup that can cause tackiness and uneven coloring.

✅ Best Answer: "We apply one flood coat, ensuring the wood absorbs as much as it needs for even coverage and long-lasting protection."

🚫 Red Flag Answer: "We apply multiple coats to get a thick finish." (This could mean they’re using the wrong type of stain, leading to excessive buildup.)

4. How Long Will the Stain Take to Dry?

Dry time depends on weather conditions, humidity, and the type of stain used. Oil-based stains generally take 24-48 hours to dry before light foot traffic is allowed and up to a week for full curing.

✅ Best Answer: "The stain will be dry to the touch in 18-36 hours, but we recommend waiting a couple days before placing furniture or heavy use."

🚫 Red Flag Answer: "It dries in just a few hours, and you can use the deck the same day." (This suggests the contractor may not be using a penetrating stain or is rushing the process.)

5. How Long Will the Stain Last?

A properly applied oil-based non-film-forming stain can last anywhere from 2-5 years on decks and 3-7 years on fences, depending on exposure to the elements and the quality of the wood.

✅ Best Answer: "Our stain typically lasts 2-5 years on decks and longer on fences, and we recommend maintenance coats as needed."

🚫 Red Flag Answer: "You’ll never have to stain again." (All stains require maintenance over time—be wary of unrealistic claims.)

6. Do You Offer a Warranty or Guarantee?

A reliable contractor should stand behind their work with some form of warranty or satisfaction guarantee. While natural wear is expected, a professional should offer to fix any application issues that arise shortly after the job is completed.

✅ Best Answer: "We guarantee our work for [X] months and will address any application issues if they occur."

🚫 Red Flag Answer: "No guarantees—once we’re done, it’s up to you." (This suggests they may not take responsibility for their work.)

7. Will You Protect My Landscaping and Other Surfaces?

Deck and fence staining can get messy, and a professional should take proper precautions to protect your plants, siding, and other outdoor surfaces from overspray or drips.

✅ Best Answer: "We cover nearby surfaces, protect landscaping, and ensure a clean job site when finished."

🚫 Red Flag Answer: "We’ll try to be careful, but accidents happen." (This shows a lack of attention to detail.)

8. What Is the Total Cost and What’s Included?

A professional contractor should provide a detailed quote outlining:
✔ Labor costs
✔ Stain type and brand
✔ Surface preparation (washing/sanding, if needed)
✔ Estimated drying time
✔ Cleanup and protection of surroundings

✅ Best Answer: "We provide a full breakdown of costs, including materials and labor, so there are no surprises."

🚫 Red Flag Answer: "We’ll figure it out as we go." (This could mean hidden fees or poor planning.)

Final Thoughts: Hire the Right Staining Contractor for the Job

Not all staining professionals follow best practices, so asking these key questions will help you avoid common mistakes and ensure you hire a contractor who uses the best products and methods for long-term deck and fence protection.

Key Takeaways:

✔ Choose a contractor who uses a non-film-forming oil-based stain for lasting results.
✔ Ensure they follow proper wood preparation techniques before staining.
