We are very pleased with the outcome.
If this is the same John's that operates out of Silverton (but services NW Portland too) you can't go wrong using this operation.
I (even) had some snafus; some solutions to a basement leak we tried didn't work, I got caught in the crossfire of an employee who quit -- BUT they never gave up on me or my leaky problem.
John's did not charge me for work that was not successful (they put it toward the job that finally did the trick) and the office people were always kind even though I called and called and called.
This is a group that is very experienced and does not quit on a customer.
They always do a solid job with their work.
Leaks are tricky things in old houses. John's knows their stuff and if an initial try is not successful they hang in there until it is solved.
Their prices were reasonable and everyone I dealt with was patient (even when I was not) and persisted. When I had a few "issues" with work or employees they responded positively and quickly.
This review is honest and includes problems as well as successes.
I would work with John 's again and can easily recommend them without reserve.
Very happy with the install Logan did & its working great !
