Cracks in Wood Siding

cracks in wood siding

The splits in the siding material concern me. My guess is that the siding was non installed correctly when the houses were built.

Honey TIM: I live in a landominium development where we all have split houses. Each house is covered with beveled cedar woods lap siding that splits for no reason. Our maintenance commission insists that all split boards be replaced before the exterior of a unit is painted. This seems extreme to me. I thought cedar would be a long lasting cloth. Exercise the boards really need to be replaced or can the splits boards be caulked? Jim M., Riverside, CA

DEAR JIM: The maintenance committee is doing the right matter. The boards with splits should be replaced. These splits permit rainwater to penetrate deeply into the wood and in some instances backside the woods. H2o is an enemy to painted finishes and wood that has not been treated to prevent rot. A new paint job tin can cicatrice and pare within half-dozen months if enough h2o gets behind the forest siding. Yous are correct about the longevity of cedar siding. It is a wonderful renewable woods product that contains natural preservatives. But water that saturates the wood sheathing or framing lumber behind the siding may start to rot in a short corporeality of time.

The splits in the siding material business organization me. My gauge is that the siding was not installed correctly when the houses were built. Inexperienced carpenters often nail lap siding then that each piece of siding is unable to move. Lap siding is installed and then that each piece overlaps the 1 below it. This overlap creates an excellent weather condition barrier so that rain water is shed from the siding. Rookie carpenters oft nail along the lesser edge of the siding and this aforementioned nail pierces the top portion of the piece of siding just below.

This method of nailing pins each piece of siding and makes it nigh impossible for the siding to expand and contract with changes in the weather. Experienced carpenters know that the nails from one piece of siding must non laissez passer through the siding below. If the overlap of the ii pieces of siding is one and one quarter inches, then the nail for a piece of siding should be one and three eighths above the lesser edge. This nail spacing allows each piece of siding to float and motility hands. Be sure that the painters nail the siding properly as they supplant each divide board.

When the split board is being replaced look to come across if a water barrier membrane is in identify. Years agone tar newspaper was used by carpenters beneath beveled lap siding. It is nevertheless a very effective fabric to utilise if you do not desire water to contact the framing lumber and wall sheathing. Modernistic fabric water and air infiltration barriers can also be used. These products come in large rolls and are easy to recognize. If you do not encounter whatever water barrier behind the siding, then it is vitally of import that new siding exist installed. In this case, the siding is the only conditions bulwark. Felt paper and the mod cloth barriers offer an of import second line of defense.

If yous want to maximize the life of the houses and the paint jobs exist certain that the siding is nailed with hot dipped galvanized nails or better yet, stainless steel nails. These nails take the highest corrosion resistance and are worth the extra cost. Be sure the nails are long enough and so that the nail shaft penetrates at least one and 1 one-half inch into solid wood once it passes through the siding.

The pigment task on the replacement slice of siding will concluding a very long time if the painter tin can pigment both the back and cut edges of the wood earlier information technology is installed. When wood siding is completely covered with paint, water has a difficult time getting into the fibers. If you go along wood completely dry using this method, it becomes dimensionally stable. Loftier quality paint will attach to this woods for many years.
