Question DetailsAsked on 2/21/2017

are contractor required to list part prices on invoive for extra work performed??

Lowes chagred me for an install then, I paid a additonal 485.00 for work to bring the install up to code i.e.
water heater extra gas valve, water valve and piping and vent piping then he charged me more labor.
Should he have to list prices on his invoce??

Ahhh - another box store quote then adding in additional chargeas for code upgrades. Read the contract find print - they are probably covered, but if they quoted you water heater installation without fine print about it not including code-required upgrades, then any water-heater related code requirements (different type of gas flex line or shutoff valve, air tank, etc) which are required when you put a water heater in should be included in their price and you should pay nothing extra.

Another common thing with this type of contractor working for box stores or home warranty companies, is sometimes they try to charge for extras and get it paid directly to them and the store or warranty company is not even aware they did this.


1) extra gas valve - should be one shutoff valve at the point where the flex line comes off the gas pipe - is that the "extra" you refer to ? Their quote should have included that - if they choose to not look at the worksite before bidding that is their problem.

2) water valve - if you mean a water shutoff valve above the tank, that is normal part of water heater installation - usually changing out any such valve unless it is quite new

3) vent piping - you have to vent the water heater - any required modifications, or lateral PVC venting out the wall for a high-efficiency water heater is part of the installation

I would say you have said nothing that to me is legit extra charge - and $485 extra is probably a 30-50% bumpup in cost over that quoted.

To your question - if he wants more than the quote, he has to justify to you the reason AND costs - including if you want itemization of the materials and the labor involved. You do not have to accept his billing carte blanche - if for more than the total agreed to in the contract, he has to convince you it is fair - if you don't agree to it then they can take you to court. And in some states, they cannot legally a lien against you for a total amount exceeding the contract amount.

Personally I would call the store manager and demand these charges be eliminated - and for a bit of extra clout, in many states Home Depot and Lowes illegally runs without a general contractor's license and just leans on the license (plumbing in this case) of the subcontractor they use for the install. Check state website - if they are offering contractor services without a general contractor's license you can file a complaint with the state licensing board, and in some states get a 100% refund from them.
