Alison, Buyer beware ! Look up estimate in websters. There is a price for everything and make no asumtions. Make sure you compare, Do background checks and your home work. If you are in the N.Y.C. area I would love to provide you with a full service price quote that includes everything and is itemised. please contact me at

If you are replacing windows in an old house make sure they are insulating the area where the sash cord and weight at the sides of the window are. If they don't you will get drafts and waste your money.
Also make sure they include removing AND disposing the old windows and ask if they will also do paint touch ups. I hope this helps.

Alison, I am in Central Pennsylvania and am now going through a complete nightmare following Appleby Window's, Sun rooms destroyed my home.
I can give you some advice that I encountered here personally
1) make sure that the contractor DOES apply for all building permits if they do claim to do so and it is the contract before any work begins.
2) some state, county, townships DO require Building permits with replacement windows and doors
3) make sure that they place on the contract that they in fact WILL follow ALL state and local building codes ( installing replacement windows up to code)
4) If ANY sub contractors are used by the contractor, when first creating the contract and NONE are included, and after the contract was created sub contractors are then hired and used (Make sure they create a new contract including the sub contractors) because there is a CHANGE in your original contract, thus they must by law inform you of such change, and proper change orders must be created and your signature for approval needs to be done to the change of contract
5) make sure you receive a itemized bill.
6) Your replacement doors, make sure in your contract it states they are ONLY replacing the original doors with the same size doors
If they change the door size, and it is not in the contract to do so,
you did not agree to this.
Where I live, a building permit is needed to change door sizes and window sizes
(Replacement windows do not need building permits where I live) except if the size of the windows and doors are changed.
Window replacement contractors when a building permit is not needed for replacement windows-doors, some will NOT install the replacements up to the local building codes. A Honorable contractor will
* Also the CLAIMS that a contractor makes on web sites and in writting does NOT hold to be true.
If your a member of Angies List? log in and look up Appleby Windows, Appleby Systems (catagories windows-doors- sun rooms) I created two reports that include photos. I DID NOT LIE.
My reports are 100% true
Good luck

We no longer replace windows or doors except on rare occasion that it'll land us a roofing job. Roofing is now what we do most, and this is by choice, though we used to install a lot of windows and doors.

Below is a copy and paste of my replacement window proposal...

1. Protectthe interior of the house with sheets and drop cloths around the work area. Itis the responsibility of the purchaser to move furniture and remove any windowtreatments.

2. Tearout <insert number here> windowsfrom the house (Sashes and tracks only. Original framing will remain). One inthe <insert locations here>.

3. Fixrotten and damaged wood as necessary to properly install new windows. Thisadditional carpentry may cost.

4. Installnew Simonton “Ultra Gold” series vinyl replacement windows. These windows willbe…

a. Whiteinterior and white exterior.

b. Doublehung with half screens.

c. Low-Eglazed glass and Argon gas insulation between dual panes of glass.

d. EnergyStar rated by the US Government.

5. Insulatethe window cavities around the new window as necessary. Cover the exterior woodwindow frame with custom bent color-coordinated aluminum then seal around thenew window caps with high quality caulk.

6. Clean the interior and exterior work area of alljob related debris.

7. This installation carries the ReliableAmerican Guarantee to remain intact and water tight for at least 6-years.

I paste this because it'll give you good information as to what to look for. Now, keep in mind that there are basically two overall types of windows (in terms of how they are installed). These windows are insert or full frame replacement. Insert are placed within the existing frame of the window. In the case of insert, most often interior trim is not disturbed. Full frame replacement is a nicer option, though much more costly in most cases and includes interior as well as exterior trim.

So what should be included? Well i want to start off by disagreeing with size. It's not your job to know size. What if the salesman measured wrong? If you sign a contract with those sizes YOU are assuming responsibility for HIS measurements. Unless you are buying some stock sizes I wouldn't recommend having the sizes for custom windows in the proposal. Brand is important, options and features are of the utmost importance!

Contingencies for unknowns such as rotten wood is also important.
