WHY D&G ・ BEVERLY'S WINDOW REPLACEMENT EXPERTS

Why Beverly Homeowners Choose D&G for Window Replacement

  • Proper Flashing & Waterproofing: Head flashing, sill pan flashing, and full integration with your home's weather barrier. This is where most window leaks start and where most contractors cut corners.
  • Premium Brands, Right Glass Packages: We install Andersen, Marvin, Pella, Harvey, and Mathews Brothers. Triple-pane, low-E coatings, and argon fills selected based on your home's orientation and energy goals — not what's cheapest.
  • Google Guaranteed with 150+ Five-Star Reviews: Google backs our work with their own guarantee. 5.0-star rating verified by homeowners across Beverly and the North Shore.

OUR APPROACH ・ HOW WE INSTALL WINDOWS

How D&G Installs Windows in Beverly

Most contractors pop out the old window and caulk in the new one. We treat every opening as a weatherproofing system — because a window is only as good as what’s around it.

  • Full-Frame or Insert — Done Right: We assess every opening to determine if full-frame replacement or insert installation is the right call. Full-frame lets us inspect and repair the rough opening. Insert works when the existing frame is solid and square.
  • Flashing, Foam & Weatherproofing: Every window gets head flashing, sill pan flashing, foam insulation of the cavity, and full integration with your home's weather barrier. This is where most window leaks start.
  • PVC Trim & Clean Finish: Cellular PVC trim that won't rot, split, or need repainting. Back-caulked joints and tight transitions that look sharp and perform for decades.

Common FAQs About Window Services in Beverly, MA

Installing or replacing windows is a significant investment. Here are answers to frequently asked questions about our window services to help you make informed decisions.

What types of windows do you install?

Double-hung, casement, bay, bow, picture, slider, and specialty shape windows in vinyl, fiberglass, and wood frames. We install Andersen, Marvin, and Pella for premium and fiberglass options, and Harvey and Mathews Brothers for high-quality vinyl. We’ll help you match the right window style and material to your home’s architecture and budget.

Old single-pane or failed double-pane windows are one of the biggest sources of energy loss in Beverly homes. Modern windows with low-E coatings, argon gas fills, and triple-pane glass dramatically reduce heat transfer. Most homeowners see a noticeable drop in heating and cooling costs — especially in older homes where the original windows have failed seals or no insulation in the cavities. We select the right glass package based on your home’s orientation and exposure, not just what’s cheapest. The same principle applies to siding for the exterior of your home.

Drafts around closed windows, condensation or fog between panes, difficulty opening or closing, visible frame rot, and rising energy bills. If you’re seeing condensation between the glass, the seal has failed and the window can’t be repaired — it needs replacing. D&G Exteriors offers free window inspections in Beverly to assess condition and give you a straightforward recommendation.

Full-frame replacement removes everything — the window, frame, casing, and trim — down to the rough opening. This lets us inspect for hidden damage, install proper flashing, and insulate the cavity. Insert replacement fits a new window inside the existing frame, which works when the frame is solid and square. We assess every opening individually and recommend the right approach for each window in your home.

Most whole-home window replacements take 1–3 days depending on the number of windows and whether we’re doing full-frame or insert installation. Individual windows take 1–2 hours each. We work room by room to minimize disruption and your home is never left open overnight.

Yes — both manufacturer warranties on the windows themselves and our workmanship guarantee on the installation. The specific warranty terms depend on the brand and product line. Andersen, Marvin, and Pella offer some of the strongest warranties in the industry. We’ll walk you through the coverage details for whichever product you choose.

Proper flashing and waterproofing practices — that matters more than the window brand. A great window installed with bad flashing will leak within years. Ask if they do head flashing, sill pan flashing, and foam insulation of the cavity. Ask about PVC trim vs. wood trim. Then check for verified reviews and proper insurance. D&G Exteriors is Google Guaranteed with a 5.0-star rating across 150+ reviews.
