Construction Industry/floor joist

Question
I own a rancher and recently discovered  that a few of the floor joists are number three grade lumber. the joists are 2x10x 12 foot long. the majority of the joists are grade 2 lumber. the home was built in 1977. I am wondering if the number 3 grade joist could cause structural weakness and therefore be replaced. I am not planning to change anything in the home but was concerned. Is my home structurally sound as it is.

Answer
Hi John;Sorry, I can't answer your question.  I am an expert in floor coverings (carpet, vinly, hardwood, laminate, rubber, etc.).  I would suggest that you resubmit your valid question to the home construction expert.  Revisit <allexperts.com> and click on home improvements, general, then click on construction, and ask the expert your question.

Cordially,

Expertise

We are a floor covering inspection service and a floor covering specifying service. We inspect all types of floor coverings in every city and town in all 50 States and Canada, for manufacturing, installation, or maintenance related problems. We also specify, so when someone is about to choose a floor covering for a residential or commercial installation, after we find out, from them, the particulars about the installation, we can suggest the proper product, installation method, and maintenance method to provide optimum life of the product. (Note that in your B2B Category, we did not find any heading related to our business, so we just chose the Construction category). So if someone has a problem with the performance, installation, or maintenance of any floor covering, we can give suggestions, without a formal inspection, the possible causes of the prolems.

Experience

We have been in manufacturing, installation, and maintenance, of all types of residential and commercial floor coverings, for many years, and for the past 13 years, we just inspect and specify.
