I have a associate in the siding field who currently does subcontract siding for Sears and I can say for a fact that they are extremely overpriced on their products. E.G. Replacement of 36" replacement door on a recent job was $1,000. The door was a Larson insulated model which can be bought at most national building supply center (Home Depot, Lowe's. etc) for approx. $100.. Sears pays the sub between $20 & $25 labor to install this door. How's that for a markup!!!!!!!
As far as their siding, they buy from the same supplier as me and pay a similar price for their materials. If you are interested in a more realistic price please post a followup message with contact info. Only 2 things would make you go to Sears for siding, a need for financing or you have money to burn. I have been in business for 8 yrs. and my partner has been in business for approx. 30 yrs.. Neither of us have been sued for our work (quality or materials) and I doubt we would be able to get a good nights sleep if we screwed people over like Sears does regularly.
