Pergola / August 26, 2018 / JulietteHughes
A pergola is a structure which creates a cool shaded and pleasant area beneath. Support columns run along the sides connecting to various types of latticed framework above. It is most common to leave the sides of the structure open while the top may be covered by a variety of plants or vines across the top. You can certainly train your plants to climb to the top of your pergola so choosing things such as roses grapes or jasmine are most appropriate. Climbing plants or vines are not a requirement however and choosing what you want your structure to look like will depend on your own personal likes. Professional pergola builders will often incorporate their structure into a trellis or gazebo offering even more accents to the garden.
Also any iron fittings may rust and cause red stains which may react with other pigments or stains. To prevent this stainless steel nails may be used and a constant vigil kept to encourage the Pergola to stay dry. A commercial mildew remover or other multi-purpose cleaners and help keep the roof spotless. Stains that are caused by the reaction of water deposits on the wood may also be removed by washing it with cleaners. Chalking is another form of discoloration which is caused by weathering of paint or disintegrating of pigment particles which appear as a powder.
So while buying wooden pergolas ask their manufacturers if they are partially notched or fully notched. Buyers should be aware that notching creates interlocking joints and this fortifies the structure. Also notching insures that all your timbers stay straight and true over the decades because they cannot move. Most manufacturers skimp on notching partially or completely to reduce their construction costs and will tell you that hardware will take care of the issue. It does not. If just one of your Pergolas timbers has hidden stresses in it (quite common) as it weathers over the years it will turn twist or sag.
