It's just a matter of removing the old mortar material, cleaning out the opening, and then applying new mortar in the space.

Or another type of coposite material. 

If you were in my area I'd offer to help and/or give you a deal on some spare materials we have per the above. 

We got the inspection back today; the issues are as follows: mold beyond the surface mold we originally noticed when checking the house out, wood rot in left side floor, damaged roof joist, poor ventilation in the attic and mold, many of the chimney bricks are loose, standing water in crawlspace--potential mold, leaking shower and toilet leading to damaged floor/ceiling underneath, plumbing material issues, electrical not all properly grounded. 

I can see in places like CA where they might be more popular but on entry level to mid level houses many will not want to spend the money.My picture and video guy does mainly weddings now as his bread and butter and corporate company pics to use on marketing materials and websites. 

I have 99% of my materials list and 99% of my SOW completed.

I'd even ask them to break down the material for you.

If the roofer needs to replace portions of the roof sheathing you have a price upfront that can be used to calculate the Change Order for replacing the sheathing.I think in the past I've been quoted around $35 to $50 per sheet (labor & material).

I was hope if anyone would be kind and provide some honest insight of cost of building a two bedroom , cabin with kitchen , bath using sustainable material possible .
