This is a renovation principle to live by:
Whenever possible, get three bids for home improvement work. But don't assume that the bids will come back apples to apples.
Resist the temptation to just go with the lowest bid
Just because you sent the same request to three architects or contractors does not mean the cost estimates are comparable or complete. Each bid should include details in categories that you can compare.
Depending on their expertise and assumptions, bids will come back with different approaches and categories.
What do instead:
Compare assumptions: Put them side by side in a spreadsheet
Look for gaps:
Ask additional additional questions
(Let's assume each delivers the same quality of work, which isn't necessarily true.)
Let's say you're renovating and expanding your primary bathroom. You've narrowed it down to your top two. If it's no outlined in the bid, don't assume it's included. Bid #2 looks the lowest, but excludes a couple key categories.
Just because demolition and permits aren't included in that bid doesn't mean they aren't required.
Before you default to the lowest bid, make sure your estimates are apples to apples.
