How much will it cost me approximately to have replcement windows installed if I supply the windows

It would help to have a lot more information here for anyone to be able to give you any sort of ballpark figure. What kind of windows? How many windows? Would the person putting the new ones in also have to take the old ones out and also do something with the old ones? Where is the location where the work will be happening? (Labor prices will vary greatly, depending on the location.) Those are just some of the questions that I can think of right now that need to be answered. Thanks!

It depends ,but for the avg. DH vinyls its anywhere from 125.00 to 250.00 per professional install. The more you have the cheaper the install. A quality installer insures proper insulation as needed and customizes the exterior aluminium extensions/sill -casings along with sealants both in and out for a proper weather tight job. I been doing home improvements over 30 yrs now.
