Frequently Asked Questions

How long has Nova Installations been in business?

Nova Installations is family-owned and operated by Art and Tom Dunn. Open for business since 1982, we are licensed, bonded, and insured.

How much will it cost?

Pricing a job for windows, doors, siding, or other home improvements, unfortunately, can’t be done over the telephone. We like to look at the structure and its surroundings, because you may want to see the products that we offer. The good news is that estimates are free. Call us at 703-378-6596.

Is Nova Installations licensed, bonded, and insured?

Yes! We’re also members of the Better Business Bureau.

Do you have any references?

We are happy to provide references in your area for similar projects. Email your request to [email protected]. You can also visit local review sites like Consumer CheckBook, Google, Angi, or Yelp to read unsolicited reviews left by homeowners like you.

Are your products guaranteed?

All our products are guaranteed; some are guaranteed for life. We’ll be happy to go over the warranty information with you. Stop by our showroom or call us at 703-378-6596.

Is window installation messy?

It’s not as messy as you’d think, and we clean up after ourselves. Installing a new window can be messy from sawdust and drywall dust. Most installations can be done in a day or two, and 90% of the work is done from the outside.
