I have grown fond of the 2.5 inch angled Purdy, nylon (I think) $14.

You will be creating a lot of work and scrutiny to move the pea from under one shell to two inches over, under shell #2. 

The backyard has a concrete patio that you can see has sunken in a few inches and sloped in towards the house. 

Set your rules and tolerances ahead of time, and then don't budge an inch. 

Between going a little over your reno bbudget, adding in closing costs, carrying costs, financing costs and your total costs could inch toward the bank's appraisal value.

Some people said 6 inch pipe but some said 8 inch, i need your opinion. 

I will be putting a section in the lease about living in a historical house that states the house has historical features such as this banister and landing that has a gap of more than 3 inches between the posts, the current standard, and that a child could put his head through the spacing, and that the banister height is lower than is currently used for fall prevention.Other things that are not historical such as putting in the GFI outlets by the sinks, I just do for the safety factor. 

For him to properly do it, level his sidewalk, it would be an inch higher if I don't replace my slab.

This is a massive sag, maybe 10-11 inches.

@Cassandra Sifford In the management game, when you give people an inch they’ll try to take a mile.
