Ways to lower your Durham price
- Do the cheap exterior fixes first — gutters, downspout extensions and grading solve many wet basements for under $1,000.
- Choose interior drain tile over exterior excavation unless the wall itself is failing.
- Get bids from waterproofing specialists and a general contractor; approaches and prices differ enormously.
- Ask about a transferable lifetime warranty — it holds value at resale.
- Install the sump and drainage before finishing the basement, never after.
