Wood Sealing That Lasts From the Inside Out
If you’ve ever stripped, sanded, and re-stained a deck in Indianapolis, you already know surface-film sealers don’t last. Most products on the market sit on top of the wood as a clear or pigmented film. UV breaks them down. Freeze-thaw cycling cracks them. Water gets underneath. Within 1–3 years, you’re back where you started — with a peeling surface that needs to be stripped before you can do anything else.
Permanent wood sealing works differently. Our polymerized silicate sealer carries silicates deep into the wood fibers, where they react with the lignin, cellulose, and atmospheric moisture to form an insoluble silica network bonded inside the wood itself. The wood becomes mineralized — protected from the inside out. No film. Nothing to peel. Nothing to fade.
That’s why we can back it with a 25-year product guarantee, and why it’s the right choice for decks, fences, pergolas, retaining walls, and any other outdoor wood you want to stop re-doing every couple of years.

SIDE-BY-SIDE
Permanent Wood Sealing vs. Traditional Stain
The difference comes down to where the protection lives — on top of the wood, or inside it.
| Feature | Our Penetrating Sealer | Traditional Stain or Surface Sealer |
|---|---|---|
| Lifespan | Permanent — 25-year guarantee | 1–3 years before fade or peel |
| How It Works | Mineralizes inside wood fibers | Forms film on the surface |
| Peels or Flakes? | Never — no film exists | Yes — within 1–3 winters |
| Breathable? | Yes — moisture escapes naturally | No — traps moisture underneath |
| UV Resistance | Mineral network resists breakdown | Pigments fade in 1–2 seasons |
| Rot & Pest Resistance | Active — high-pH silicates | Passive — depends on intact film |
| Re-application | One-time | Strip + re-stain every 1–3 years |
| 25-Year Cost (400 sq ft Deck) | $3,500–$5,500 once | $11,000–$26,500 over time |

Frequently Asked Questions
How long does wood sealing last?
Our penetrating silicate wood sealer is permanent. Because it mineralizes inside the wood fibers rather than forming a surface film, there’s nothing to peel, fade, or wear off. It’s backed by a 25-year product guarantee.
What's the difference between wood sealing and wood staining?
Wood staining adds color through a surface film and lasts 1–3 years before fading or peeling. Wood sealing penetrates and bonds inside the wood, providing permanent structural protection. Many homeowners do both: stain for color, then seal for lifespan.
Can you seal a deck that was already stained?
Yes, but the old stain needs to be stripped first. Our penetrating sealer requires direct contact with the wood fibers to bond. We handle stripping as part of the prep work.
Will the sealer change the color of my wood?
Our penetrating sealer is clear and won’t significantly change the natural wood tone. If you want a color change, we can apply a stain first, then seal over it for permanent protection.
Is wood sealing safe for kids and pets?
Yes. Our wood sealer is water-based, low-VOC, and non-toxic once cured. Decks and fences are safe to use again within 24 hours of application.
What types of wood can be sealed?
Our sealer works on virtually all wood types: cedar, pine, pressure-treated lumber, redwood, ipe, and exotic hardwoods. It’s effective on decks, fences, pergolas, retaining walls, and outdoor wood structures.
How quickly can you schedule wood sealing in my area?
We typically schedule within the same week. During peak season (May–September), we recommend booking 1–2 weeks ahead. Call (317) 548-2002 for current availability.
Does the 25-year guarantee cover everything?
The 25-year product guarantee covers our penetrating wood sealer specifically. Wood staining, decorative finishes, and surface coatings carry different warranty terms. Application is covered by our one-year workmanship warranty across all services.
