Termites ate the ends of our floor joists

Dear Home Inspectors,

I value you advice! I have a dilemma. My 20 by 30 one story cottage had termite damage before we bought it and they ate the ends of practically ALL the floor joists and the subfloor in spots. They are long gone. The finished floor above is old tongue and groove soft, but nice. The house is un level and needs a central beam and footings which are in the plan.

Here's the $64,000 questions PLEASE...

1. Should I cut out the old joists and replace with new 2 x 10 pt, adhesive on top and angle screws into existing subfloor?

2. Should I leave the existing floor joists and build a new structure beneath that the house sits on?

3. Should I bite the bullet and cut everything out?

Again, I so very much appreciate your learned advice more than I can tell you. -David

Get the pest contractor in there first.

I agree with the above. Get a pest control person in there to check and make recommendations, and a foundation repair contractor or framing contractor. We can't evaluate the conditions from photos of the floor above.

Thank you.

"typically" it makes no sense to ever rip out the old stuff when it is much easier to leave it in place and sister up the damaged members with same size lumber. If only the end is damaged, you don't need to sister the entire joist, just go a couple feet past the damaged areas and nail it properly. It is impossible to evaluate a situation without seeing it and my comments are intended to be "rule of thumb"

Termite infestation can be frustrating. As with any household pest concern, preventative measures can be taken to ensure that you don't have a repeat occurrence of an infestation after you have successfully rid them from your home. As a homeowner, it is important to regularly monitor the home, and have a professional like pest exterminator Essex county NJ come to the home, to treat the home, with preventive products.

I think it is better to consult pest control professionals in this matter.
