The fasteners are of insufficient size and strength to withstand the load of the materials they are meant to uphold. It may also be that they are of inappropriate material to withstand the environment they are exposed to and may be vulnerable to weathering, corrosion or fungal decay which would compromise their strength.
Les was on time and did an extremely thorough inspection of the property as a pre-purchase condition. He was cordial, polite and interacted with us at a very professional level. After completing the inspection he walked us through the various levels of inspection. He gave us time to answer our questions and backed his advice up with the data he had collected. I have absolutely no problem commending him to others. Money well spent.
