BPs community,
So I have had four contractors come out and do bids on a basement that I am planning to convert into a legal third unit. The bids have been very inconsistent with numbers ranging as low as 45k to as high as a 100k. At this point, I am trying to figure out if the contractors offering bids between 80k and 100k are overpricing their job and trying to finesse me. What I did notice is that the contractors that were charging larger bids were those that had bigger contracting companies and the ones with the smaller rates was not as big of a contracting company but still related they could get the job done at a much cheaper price. At this point, I am not looking for an extravagant finish in the basement just an additional unit that is nice, comfortable, and livable. Any advice?
I would look at the bid breakdown. The bids should not just say "Basement Conversion: $70,000". At the highest level of detail, the bid should have a detailed breakdown with the prices for each room, "Kitchen Cabinets, $XXXX; Kitchen Tile Floor, $XXX; Kitchen Drywall, $XXX; Kitchen Plumbing, $XXX". A lower level of detail might say, "Drywall Entire Basement, $XXXX; Electrical for entire job, $XXXX; Plumbing for entire job, $XXXX".
You should be able to compare the bids to see if one is significantly different than the others. For instance, the plumbing on one bid might total $4000 more than the lowest plumbing estimate, and $2000 more than the highest plumbing estimate. Or the drywall might be way too low on another estimate to be believed. Comparing the estimates should reveal the discrepancies.
If any of the contractors delivered an estimate without any detail you should either ask for a detailed breakdown, or simply eliminate that contractor from consideration. Either he's too incompetent to know how to create a bid (which likely means his bid is incorrect and he grossly overestimated or underestimated his quote,) or he padded his bid and is hiding that by not including the breakdown in the bid itself.
Being a smaller company is no excuse for not providing a breakdown of the pricing. Any contractor should be able to provide a competent estimate.
