I have written briefly about how Walnut lumber is graded differently from other North American hardwoods, but it seems that customers are still surprised by the apparent lack of quality in Walnut lumber. Usually these inquiries are met with surprise on the part of our grading team, as our graders were quite proud of the quality of Walnut that left our yard. What it really comes down to are two … [Read more...] about Walnut Lumber Grade Explained

Ipe Deck Maintenance: New Decking is Not a Finished Product
When you buy decking boards, they are already planed on 4 faces (S4S) and usually have the sharp corners eased (E4E). Depending on whether you are face screwing or using a clip system, there may or may not be a groove routed on the edges. This is a product ready to install right? But is it a finished product? Absolutely not, and this is where many homeowners and even contractors get confused and … [Read more...] about Ipe Deck Maintenance: New Decking is Not a Finished Product
Kiln Dried May Not Mean What You Think It Means
We know that lumber needs to be dried before using it in construction, and most of us know to ask for kiln dried lumber. (We do know that right? Please say yes) But did you know that not all kiln dried lumber is equal? Depending on where the lumber comes from, the moisture content of your kiln dried material may not be what you think it is. 6-8% is the accepted moisture content of kiln … [Read more...] about Kiln Dried May Not Mean What You Think It Means
Do you really Need Marine Plywood?
That depends (sigh)... How do you plan to use it? What is Marine plywood used for? Marine plywood is any plywood made to withstand the elements of nature, specifically water. So it is used for Marine construction like boats and docks but also water front properties. As you can imagine the amount of exposure the plywood sees varies widely on whether it is used on a boat or on an ocean front … [Read more...] about Do you really Need Marine Plywood?
How to Prevent Cracks in Your Large Timbers
Easy answer: you can't... That's not entirely true. You could dry the timbers in a vacuum kiln and definitely not use them outside and keep them away from direct sunlight. Probably a good idea to speak in low, soothing tones around those timbers too. I joke, but the reality is that these cracks or checks are just the nature of wood. Checking can be controlled in "regular" sized 4/4 through 8/4 or … [Read more...] about How to Prevent Cracks in Your Large Timbers
Utile Is The Best Mahogany Alternative
Mahogany is an iconic wood for furniture and high end millwork. It has been used for hundreds of years as the prime species based on its ease of use, consistent color, and outstanding appearance. These days genuine Mahogany is not used as often.  Not so much because of availability but because the price has been tough to swallow. Regulation of the species has slowed down the supply chain and … [Read more...] about Utile Is The Best Mahogany Alternative
Wood Color Changes Explained
One thing that is difficult when working with wood is the range of colors you find within a single species. All woods will change color throughout the process from sawmill to finished project. Wood continues to change color years down the road. It fades in the sunlight, but some woods also undergo chemical changes that change the wood color. The one thing you can count on is the color will … [Read more...] about Wood Color Changes Explained
Types of Hardwood Plywood & Core Comparisons
Did you know that J. Gibson McIlvain sells plywood? It came to my attention recently when visiting customers that this was not a well known fact. Certainly hardwoods is where our legacy lies with hundreds of years in that market, but we decided to jump into plywood several years ago to offer some alternatives to our customers. Despite plywood's popularity, users tend to know very … [Read more...] about Types of Hardwood Plywood & Core Comparisons
Dark Teak Color Change is Caused by Sun and Exposure
What color is Teak? That is not an easy question to answer. Teak color is discussed a great deal. Specifically Teak color change is what drives people crazy. Wood is an organic material so it moves and changes. Anyone who has worked with wood has noticed the different look of freshly planed lumber from aged and oxidized lumber. In most cases a mellowing of the color and … [Read more...] about Dark Teak Color Change is Caused by Sun and Exposure

As we have written about on this blog … [Read more...] about Tigerwood Decking or Ipe or Cumaru: Tropical Decking Choices
Rethink How You Order Hardwoods and Millwork

This is not news to anyone reading this, but it is also not something we can just resign ourselves to … [Read more...] about Rethink How You Order Hardwoods and Millwork
What is the Proper Deck Board Spacing?
How much space to leave between deck boards? This is the most asked question about installing a deck. The easy answer is 1/4" or about 6 mm. But that answer doesn't take into account a lot of factors and can pose problems further down the road. The moisture content of the decking boards, how long they have had time to acclimate to your environment. How much sun the deck receives, how much … [Read more...] about What is the Proper Deck Board Spacing?
Yesterday’s Philippine Mahogany is Today’s Meranti
Philippine Mahogany is synonymous with boat building, thanks to the iconic Chris Craft boats from the 1930-60s. So when asked if the species will be good for exterior projects, we answer with a strong yes. Boat building tests wood in a way that nothing else will, so if a particular wood is good enough for that, then trim, windows, or siding have nothing to fear. Times have changed, however, … [Read more...] about Yesterday’s Philippine Mahogany is Today’s Meranti

Afromosia Wood is Gaining in Popularity

As styles change, materials and industries shift to meet the demand for raw materials. Over the last few years we have seen a growing demand for Teak beyond the boat building industry. Minimalist Asian and Scandinavian influenced interior … [Read more...] about Afromosia Wood is Gaining in Popularity
Things to Look For When Buying Teak Lumber
Geopolitical issues in Myanmar make genuine Teak lumber buying very confusing. Previously, the serious buyer could always discount the lower quality lumber by determining the country of origin (e.g. India, Indonesia, Cote d'Ivoire - more on these in a future blog post), as it has long been known that Burmese Teak is the standard by which all others should be judged. Now, with Burmese Teak … [Read more...] about Things to Look For When Buying Teak Lumber
Wide Plank Flooring is Beautiful but Tricky
Lately we have been running into a lot of wide plank flooring jobs. In high end remodeling and construction, these 12" and wider planks are a popular choice. But really anything larger than about 4" wide could be considered wide plank in comparison to the typical "strip" flooring products. In other words, "wide plank" is kind of a relative term. Proportionally speaking, the bigger the room the … [Read more...] about Wide Plank Flooring is Beautiful but Tricky
Wood Moves, Get Over It
As if it were some kind of perpetual motion machine, wood will never stop moving. No matter how old it is, what has been done to seal it, fasten it, or restrain it, the wood will move. Accept it, and move on. Understanding how and why your wood moves is necessary if you are going to work with this wonderful medium. Understanding how a particular species and cut moves is … [Read more...] about Wood Moves, Get Over It
