Assess Your Existing Deck Frame and Substructure
The first step in any deck renovation project is a comprehensive inspection of the existing frame and substructure. This includes joists, beams, posts, and ledger boards. Look for signs of rot, insect damage, or excessive deflection. Hardwood decking, especially dense species like Ipe and Cumaru, can be heavier than some common decking materials. Your existing frame must be structurally sound and adequately spaced to support the increased load.
Verify that joist spacing meets current building codes and can accommodate the hardwood decking you plan to install. If joists are spaced too far apart, you may experience bounce or premature wear on your new deck boards. Any compromised structural elements should be repaired or replaced before new decking is laid. This foundational assessment is critical for the safety and longevity of your renovated deck.
Comparing Hardwood Decking Species: Ipe vs. Cumaru
For renovation projects, two popular hardwood decking options, Ipe and Cumaru, offer distinct advantages. Both are dense, durable tropical hardwoods, but they have differences in appearance, performance characteristics, and price tiers.
Ipe, also known as Brazilian walnut, is often considered a benchmark for hardwood decking. Its color ranges from reddish-brown to olive-brown. Ipe is highly resistant to rot, insects, and mold, and it can last for many decades with proper care. It also carries a Class A fire rating. Ipe is available in various profiles and lengths, typically 3–24 ft.
Cumaru is a suitable alternative to Ipe, offering similar resilience at a different price point.
Considerations for Grand Rapids, MI Climate
Grand Rapids experiences a range of seasonal conditions, from humid summers to cold, snowy winters. Hardwood decking materials selected for this region should be able to withstand these fluctuations without significant warping, cracking, or deterioration.
Both Ipe and Cumaru are noted for their resistance to weather changes. Their natural oils help protect them from cracking or warping, making them suitable for areas with significant temperature and moisture shifts. While Ipe is particularly resistant to warping after moisture exposure, both species are known to perform well in demanding outdoor environments, including those with winter exposure and humidity.
Calculating Material Needs for a Renovation
Accurately calculating the amount of hardwood decking needed is crucial for a renovation project. Begin by measuring the exact dimensions of your deck surface. For example, if your deck is 12 feet wide by 18 feet long, the total area is 216 square feet. Hardwood decking is typically sold by the linear foot or board foot.
Let's consider a hypothetical deck renovation project: a rectangular deck measuring 12 feet by 18 feet. You plan to use 5/4x6 (nominal 1 inch thick by 5.5 inches wide) Ipe decking boards. To calculate the linear feet needed, first convert the width of the board to feet (5.5 inches = 0.4583 feet). Divide the total deck area by the board width to get the total linear feet: 216 sq ft / 0.4583 ft = 471.3 linear feet. It's always advisable to add 10-15% for cuts, waste, and future repairs. So, you would likely order around 520-540 linear feet of decking.
Remember that actual purchase quantities will depend on available board lengths and your cut plan to minimize waste. For example, if boards are available in 10-foot and 12-foot lengths, you might optimize your order to use full lengths where possible, especially for the 12-foot dimension of your hypothetical deck. Always confirm profile and length availability before finalizing your order.
Maintenance and Longevity
Hardwood decking, especially species like Ipe and Cumaru, is known for its low maintenance requirements compared to some other decking materials. A yearly wash with water is generally sufficient to keep the deck clean.
If you prefer to maintain the original rich brown color of the wood, an annual application of a UV-blocking sealer or oil is recommended. Without this treatment, both Ipe and Cumaru will naturally weather to a silvery-gray patina, which does not affect their structural integrity. This natural weathering is a common choice for those who appreciate the look of aged wood and prefer minimal upkeep.
Before you order
- Inspect existing deck frame for rot, insect damage, and structural integrity.
- Verify joist spacing is adequate for chosen hardwood decking and local codes.
- Measure deck dimensions accurately to calculate material needs, adding waste factor.
- Compare Ipe and Cumaru characteristics: color, durability, Janka rating, and price tier.
- Consider the aesthetic preference: natural silvering or maintained color with UV sealer.
- Confirm available profiles and lengths for your chosen hardwood species.
- Plan for professional installation due to the density of hardwood decking.
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.

Questions to help you decide
Can I reuse my existing deck frame with hardwood decking?
You can potentially reuse your existing deck frame, but it must be thoroughly inspected for structural soundness. Hardwood decking, particularly dense species like Ipe, can be heavier than other materials. Ensure your joists, beams, and posts are in excellent condition and properly spaced to support the new load and meet local building codes. Any compromised elements should be repaired or replaced.
How do I maintain the original color of my hardwood deck?
To maintain the original rich color of hardwood decking like Ipe or Cumaru, you should apply a UV-blocking sealer or oil annually. If left untreated, these hardwoods will naturally weather to a silvery-gray patina over time, which is a common and structurally sound aesthetic choice for many homeowners.
Is hardwood decking suitable for the Grand Rapids climate?
Yes, hardwood decking, particularly Ipe and Cumaru, is well-suited for the Grand Rapids climate. These tropical hardwoods are known for their natural resistance to weather changes, including moisture exposure, extreme temperatures, and pests. Their density and natural oils help prevent warping and cracking, making them a durable choice for areas with distinct seasonal variations.
