These boards are all nailed within the last inch to half inch of the board. Would there have been a better way to do this? Looks like many of them split.
Thanks again, Paul-Marc |

yeah, they should be pre-drilled at the butt ends.

Screwed, not nailed. Hopefully there are more serious things to worry about. I wouldn't say anything. (When 2 boards meet at the same joist, there isn't much room in which to place a fastener.)

If you blunt the point of a nail it will not split the wood as it did in this case.
Screws would have been a better chioce of fastener, they also are less prone to back out creating loose boards. There are fasteners that allow you to secure the deck boards from underneath then you won't even see the heads. |

Pre-drilled joints would be best practice. How was it performing and what are the implications? How high is the deck from grading? Is it pressure treated wood with an ACQ deck board screws?
I would probably describe it with a pic in my report in particular if it does not feel like it is performing well. Mark Nicholet Apple Home Inspections LTD My Blog CAHPI(BC) Associate member InterNACHI member Infrared-Certified BC Licence # 47592 Last edited by mnicholet; 5/24/09 at 8:41 PM.. |

As has already been said, those are square drive screws and not nails, but would like to mention that unless the screw is designed for this purpose, pre-drilling is the only option.
http://www.dealerslumber.com/grk.html There is a screw that I have used many times and does not split the wood whatsoever in this example and it is this one. Excellent. ![]() GRK Fasteners are the highest grade of fasteners on the market. Their innovative design combined with a high quality German Steel produces a consistent, durable and time tested product. The only fastener on the market tested by ICC! GRK Fasteners have ratings on sheer strength, pull out, head pull through, tensile strength and more!The tips of the screws are 'W-Cut' & 'Zip-Tip'. 'W-Cut' is a patented thread design which act like a circular saw blade, cutting through any fibrous materials with ease. This unique design reduces the amount of torque required to install the screw and maintains a high pull-out strength. By cutting through rather than pressing fibers aside the 'W-Cut' also reduces material splitting. The 'W-Cut' design is available on all GRK screws 1-1/4" and longer, except Top Star. GRK's 'Zip-Tip' is designed for fast starts in all fibrous materials. The revolutionary Climatek coating is featured exclusively on GRK products. With a gold coated appearance it is the only suck plating which offers rust free protection of 29 Kesternich cycles. Climatek is ideal for your outdoor projects! GRK offers a Limited Lifetime Warranty to original retail purchaser, please come in to Dealers Lumber for additional details. GRK's R4 Self-Countersinking Screw has six self contained cutting pockets which act like a router and transport the "drill dust" away! The GRK R4 is Climatek Coated and is also available in Stainless Steel. The R4 has over 60 sizes available, 4 x 3/8" to 12 x 12". Multi-use: wood, particle board, plastic, sheet metal, cement fiber board, composite decking, wood decking. ![]() The decking in the pictures looks like a Wolmanized Product but not sure. Hope this helps.

Thanks everyone. Your comments are much appreciated! The deck was in good condition. Screws indeed. Pre-drilling would have been the better approach it seems... It is a new deck, performing well at the moment.
Thanks again! Paul-Marc |

So... you can bid higher and risk losing the job, or you can pre-drill for free, or you can get the job, sink the screws and not worry about it. It's not a perfect world...

I have installed many wood decks with "T" clips, where no screws are visible from the top. The first board installed gets screwed from both sides, and the next has a "T" clip nailed to it, which slides under the first board, and screws down from the side, on the other end. This allows the deck board to dry and contract without splitting, because it is screwed down only on one side, but it is securely fastened to the joist. Many boards will shrink as much as a half an inch, and this method allows the boards to increase the gap between them, rather than split up the middle. This is a great method for hot tub decks, where you will definitely be walking around in your bare feet. But as Kenton stated, many people are bidding, and this is a more expensive alternative.

Guys, even when pre-drilling this can still occur......much of it has to do with the moisture content, especially dealing with pressure treated lumber.
PT lumber is a pain to deal with......if its not splitting, its twisting or warping.......if a person doesn't like the results then I suggest a composite material (mold issues with some composites) or do a concrete patio / porch next time. One also has to consider that you have about 3/4 of an inch at butt ends....not much to work with. As far as I am concerned, its cosmetic...... Jeff |

Guys...
Joe F said it best. Is this what our profession has turned to? So long as the materials were still aligned and the deck constructed of PT lumber, then who really cares. Will we start to document dimples in the wallboard next? Sure, as a point of discussion this is useful. Fasteners always makes for fascinating discussion points. But pointing out this degree of normalcy in a 10 year old deck or WHATEVER is overkill. Maybe we should be concentrating on WHAT REALLY MATTERS, or have we forgotten what that is about. Sorry to be critical, folks, but you've got to be kidding me... Last edited by jfarsetta; 5/26/09 at 11:48 PM.. |

I have to agree with Joe, I likely would not have mentioned this at all.

I would not have called it out either, but at least I know what caused it and some might be interested in knowing also.
There is no harm in having these discussions. That is how we all learn, from the causes and standard installation procedures, then on the speak softly side of the inspection, one is able to explain to clients what the causes are and not necessarily have to find it's way into the reports. Some clients are apt to question you on things of that nature. Be prepared to answer intelligently. Not a defect in my book but a poor installation like all other things we see from various inspectors that share their photos.
