Painting, fencing, a new walkway or exterior door replacement are all straightforward jobs a licensed contractor can quote directly, and a written quote comparing materials and labour is the only reliable way to know what your specific project will cost, since prices move with lumber, labour rates and the season.
Permit status is the detail that actually affects value later. A fence built to the City of Saskatoon's bylaw height and setback rules, or a deck built with a permit and inspected along the way, holds up under a lender's or appraiser's review in a way an unpermitted version does not, and a buyer's own $400 to $600 home inspection will often flag work that was never signed off.
Get the quotes for the cost question and get the permit history straight for the value question, because those are two different answers hiding inside one deal-sounding question. Get your hand-reviewed valuation from Joel Dyck.
