Two leak proposals may cover different things: diagnosis, a surface repair, removal of surrounding material, or replacement of a larger detail. Comparing the final price without those distinctions can make an incomplete scope look attractive.
What to do next
Request the suspected cause, included materials, access assumptions, and exclusions in writing. Ask whether investigation is included if the source remains uncertain. Use the same photographs and history for each bidder so their recommendations start from comparable information.
