I have had all the windows in my house replaced by Nestor. The installers were efficient, professional and hard working. They cleaned up well both inside of my house and outside. Customer service called during the installation to ensure I was happy with the service. I am pleased with the result and the ease of the entire process. Would highly recommend.


I used Nescor to install two new windows in my house. High quality product with a lifetime warranty. They completed the job well ahead of the estimated time given.

5.0 Lynne S. Ware, MA

Nescor's sales rep explained the product and the way it works in great detail. I felt well informed to make my decision. The installers worked quickly and precise and showed, explained the installation process and answered all questions I had. Customer service was the same, answered my questions after job was completed. Very pleased with Nescor's service and would highly recommend them.

5.0 Helen S. Avon, CT

The Nescor support team and replacement windows are AMAZING! Part of the cost includes a lifetime warrantee and the attached customer service is prompt, reliable, and goes way beyond normal levels of excellence. The technicians aim to empower customers with information about the products purchased and are always available to answer questions and make a personal visit to resolve infrequent issues. I had an issue with a screen for one of my replacement windows and a service tech was kind, courteous, followed all COVID PPE requirements, resolved the issue quickly, and educated me about the issue so that if I were to encounter it again, I could solve it myself. This is customer service at its best.

Completed work efficiently in one day, left property neat and clean. Arranged financing.

5.0 Linda S. North Adams, MA

Within a few days of contacting Nescor, the Vice President came to our home and outlined exactly what they would do and how they would do it. In a few days the dumpster arrived along with a port-a-potti, shingles and other materials. Nescor had arranged to remove our solar panels with our solar company which saved us months of waiting. Eight people showed up the first day and went right to work. The men were very professional, very polite and great workers. The whole house was tented so none of our home would sustain any damage.The next day, about four men came back and finished the job. We have a 1400 sq. ft. ranch with a breezeway and garage. To say we are happy would be an understatement. The shingles look great and there now is a special ice and water barrier under the shingles. Everyone who walks by tells us how great our house looks. And they even put our dish back up on the roof!

5.0 Elcie S. Taftville, CT

I really like my windows, I use less heat now and my house stays warm. Their job is amazing.

5.0 Vicky S. Westbrook, CT

Awesome crew! Very professional and left yard clean and debris free! Highly recommend NESCOR if you are looking for a metal roof!


I called Nescor twice to have an inspection on the job, due to no response I had to hire a lawyer due to poor quality workmanship and instead of settling with me, Nescor hired a lawyer to fight me.

5.0 Clifford J. Windsor Locks, CT

Do excellent work any problems right on it. Cleaned up everything. Definitely would recommend Nescor .

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
