I got 3 estimates for crawlspace repair. They were all very different. The house Inspection gave something else. American Standard people were very convincing that I should have all 16 piers repaired, not just 2. Now the floor is more uneven. And, 2 companies said that I should encapsulate. Not Amer. Standard. Prices vary. Make sure that all you want done is included in your estimate and that you won't have to bring in other companies which will greatly increase the price.
