the guide

Installation over brand

A mid-range window installed with proper flashing and air sealing will outperform a premium one installed poorly.

What affects the price

Unit count and size, frame material, insert versus full-frame installation, and repairs to rot found in sills and framing.

Reading the label

The NFRC label lists U-factor and solar heat gain. ENERGY STAR publishes the criteria for the Northern climate zone that includes Pennsylvania.

Rules and paperwork in Pennsylvania

  • Pennsylvania’s Home Improvement Consumer Protection Act requires most contractors who perform home improvements to register with the Attorney General’s office and to give you a written contract for any job over $500. The registration number belongs on the estimate and the contract — ask for it.
  • Building permits in Pennsylvania are issued under the Uniform Construction Code by each municipality or the inspection agency it appoints, so the local building or codes office decides what needs a permit and an inspection.
  • In homes built before 1978, federal rules require firms that disturb painted surfaces to be EPA Lead-Safe Certified and to use lead-safe work practices.

Rules change — confirm current requirements with the agency and with your municipality.

Questions to ask before you hire

  1. Insert or full-frame replacement, and why?
  2. How will the opening be flashed and sealed?
  3. What do the product and labor warranties cover?
  4. What is your Pennsylvania Home Improvement Contractor registration number?

Frequently asked questions

Is a permit needed in my town?

Same-size replacements often are exempt; new or enlarged openings usually are not. Ask your municipality.

Will new windows pay for themselves?

Energy savings alone take many years. Comfort, operation and maintenance are usually the better reasons.

Is lead a concern?

In homes built before 1978, yes — window replacement disturbs painted surfaces, so the firm must be EPA Lead-Safe Certified.
