Yes. Combination projects are common, for example, windows and doors, or windows and siding. Keeping the work under one contractor means color, trim, and installation detail stay coordinated, and it usually shortens the overall timeline. Opal quotes each service on its own line inside the same proposal so homeowners can phase the work if needed.

Window replacement (pocket or insert) leaves the existing frame in place and installs a new window unit inside it. It's faster, less invasive, and best for homes with sound frames. Window installation (full-frame or new construction) removes the frame, trim, and flashing entirely, which is the right choice for damaged frames, remodels, additions, or new openings. Opal assesses frames during the consultation and recommends the right path.

Siding cost depends on the material (vinyl vs. James Hardie fiber cement vs. specialty profiles), the square footage of exterior wall, how much of the old siding needs to come off, trim and detail work, and prep discovered behind the old cladding. Opal gives a scoped written estimate before work begins and does not add hidden fees during installation.

James Hardie fiber cement is the strongest all-around choice for most Chicago-area homes. It resists rot, pests, and fire, holds color well, and is engineered for freeze-thaw climates. Vinyl is a strong, lower-cost alternative, especially for straightforward elevations. Stone veneer works well as a premium accent alongside either material.

Fiberglass is the most common recommendation because it's low-maintenance, energy-efficient, and available in wood-look finishes. Steel is the strongest security option and pairs well with front elevations that want a clean, contemporary line. Wood is the right call when a historic home or high-end elevation calls for real grain and custom finishing. Opal walks through options with the home's style in mind, not a template.

No. Opal only installs products sourced through its certified manufacturer partners: Kolbe, Andersen, ProVia, and James Hardie. That's how each project stays covered by both the manufacturer's product warranty and Opal's Five Year Workmanship Warranty.

Most window replacement projects take one to two days on-site after product arrival. Entry and patio door replacements are typically same-day. Full-home siding projects usually run several days to a couple of weeks depending on size, prep, and weather. Product lead times are separate. Many manufacturers require four to ten weeks between order and delivery. Opal confirms the specific timeline for each home during the proposal.

The Five Year Workmanship Warranty covers the quality of the installation labor on every Opal exterior project. The product warranty from each manufacturer covers the material itself. Together they protect both sides of the project: the install and what was installed.
