Have my first quote - how does it look?

[dis00]

I have my first quote in for extending my attached 2 car garage into a 4 car garage. I am extending at the back of the garage. The approximate is 420 square feet.

I have attached a copy of the estimate.

I have a couple of question for those that have been through a similar process

does the cost seem reasonable? $36k ($86 per square foot) im in Ohio. I asked them to separate the drywall in case i did that myself.

I hope to put in a lift eventually (ideally a flush mount, full rise scissor lift) and would have them poor the concrete with that in mind. They have quoted for 4" is that thick enough?

Any thing else jump out?

Thanks in advance.

In regards to the concrete, I would pour thicker, at least where the lift would be. I cannot comment on the price as I built a pole barn but from first looks, for an addition to house that is stick-built, I would say that thats probably on par

I added 2000 square feet of shop attached to the house recently. Paid less than that per foot by about $10. Can't see your quote for details. Mine was 22 x 25 garage with normal ceiling and 30 x 50 shop with 12 foot ceilings and decked attic, plus small bathroom. All brick, all insulated and finished interior plus additional driveway to get to it. You definitely need to get multiple quotes and references. Anything you can do yourself is better. They normally have to firetape the sheetrock to pass inspection, but you can paint and trim later. Location plays a big part. Both in values, costs, and regulations.
4 inch is plenty thick enough, but if you are going flush mount in floor it won't matter as you have to bust all that up anyway where the lift will go. Definitely get the ceiling height now for a real lift. 12 foot minimum.

this may help
Can't verify accuracy, but I tried 4200 square feet with 12 foot ceiling, insulated and sheetrocked but basic as possible and it said $35,911.

I did mine for the heck of it and it came within 10%

I have a 1600 sq ft pole barn, with a 12 ft ceiling. Concrete floor, pretty basic. This estimates it at 36k just for matieral. A total cost of 59k. I built it myself in 89, added the Crete 10 years ago. Basic electrical, I don’t have 20k into it. Maybe 12? But things are much more expensive now. And I paid myself 0 for labor.

To me, that seems very expensive but we really can't answer your question with the lack of information.

We have no idea of what kind of dirt work is involved.

Type of foundation or type of construction. I'm guess you need footers 40-48" deep. Going with block or concrete ?

2x4 or 2x6 walls ? Rafters or trusses, scissor or attic trusses ?

Type of siding? Vinyl, brick, stucco, metal, or hardi-board

roof material, are they tying in to the old roof, completely reshingling the entire roof upon completion of new section ?

Any doors, windows ?

Putting in a header and removing a pre-exisiting back wall ?

thanks for the replies. I can't get the pictures to show up put if you click on them it give a somewhat details list of what is included in the estimate. I am waiting on an estimate from one other company.

2x4 walls
The quote doesnt specific anything about trusses. I did mention that I want a vaulted ceiling for the lift (my current garage has 9 ft ceiling with attic space above) so I'll follow up on that.
the siding will be vinyl to match the house
the would be tying the roof into existing roof with a reverse gable i believe its called
just 1 man door (no garage door as there is one on the existing garage)
quote include 1 vinyl window
the would be putting in a header

Using the garage cost calculator it comes in at $16k for parts but this includes $3500 for exterior doors which wouldn't be the case for me. But it only accounts for $550 for electrical. Giving that I need to move the meter i assume that my costs there would be significantly greater than that.
