Uneven pavers adjacent to house
I am new to the boards & to home maintenance. Please excuse basic questions...
We have an inground pool surrounded by concrete pavers. Over a few years, 3-4 of the pavers that are adjacent to the house have begun to settle unevenly: some of them are tilted toward & some tilted away from the house & none are flush with the other pavers around the pool. We were concerned that this cosmetic issue may lead to a more serious functional issue: rainwater (not pool) may drain/leak into foundation of house. Since we do not have a basement, we don't have visible clues that this is a problem. We've sought estimates from contractors & everyone tells us yes that it is a problem requiring expensive work but no one seems to give a consistent & clear explanation. We're concerned that parties who want our business are not the best source of advice on whether there is an actual functional problem in the first place. Can unevenly settled pavers lead to water drainage into foundation of house & how can we verify & soundest solution? Thank you.
