For example,  I had a bathroom redone, I also had our front iron railing fixed (new feet welded in, cleaned and painted) and resurfaced the cement steps, and some landscaping.  

The pool will need to be resurfaced in 5 years for about $12,000 They need to put away $2400 for that.Look at everything you would need to replace over a 20 year period and figure how much does it cost and how much longer will it last.

Were the cabinets painted over, resurfaced or changed altogether?

Moved a couple walls, remodeled two bathrooms, added a third bathroom, remodeled kitchen, new windows and doors, added a window, resurfaced pool, landscaping front and back, added a back patio area, interior and exterior paint, roof repair, termite treatment, new flooring throughout, etc, and some surprises when opening up walls and floors.Sweated for a month with no offers then got 2 full price offers the same weekend.    

As part of the deal, we got a $2,200 credit to resurface the hardwood floors (approximately 800 square feet).

Tubs on the other hand can be resurfaced and it's cheaper to resurface a tub than to remove and install a new one.

They do great work if you are considering refinishing or resurfacing! 

"Gotta resurface that asphalt driveway due to 2 noticeable chips...violates code and its an eye sore".My point?

Drive down Silver St in Dover (A grade neighborhood), which has a perfect newly-paved street, then go to the good side of 108 north of downtown (where I live, solid B+ Neighborhood), which has streets in good condition, but Unitil cut them up a few years ago and they haven't been resurfaced yet. 

I resurface cabinets and countertops.
