What does aluminum capping on a dormer or bay window actually do?

Aluminum capping covers the existing wood trim on dormers and bay windows with a formed aluminum shell. Wood trim absorbs moisture, develops rot, and needs periodic repainting. Aluminum capping eliminates all of that. Once installed, the trim holds its color and shape without any seasonal upkeep. It also provides a cleaner, more finished look than painted wood and holds up well against Missouri's spring hail storms and humid summers. The result is a maintenance-free exterior detail that protects the structure underneath while improving the overall appearance of the home.

Can metal or copper roof components be added to an existing dormer?

Yes. Exterior Siding Solutions installs premium metal and copper roof components as part of dormer enhancement projects. These accents are one of the most effective ways to give a dormer a high-end architectural finish. Copper in particular develops a natural patina over time that adds character and visual distinction to the roofline. These components are installed alongside aluminum capping and other trim work so the entire dormer reads as a cohesive, intentional upgrade rather than a patchwork of separate repairs. This service is available to homeowners in Ballwin, Chesterfield, Wildwood, and surrounding West County areas.

Which window brand do you use for bay window replacements?

Exterior Siding Solutions installs Provia windows for replacement projects, including bay window applications. The window installation is coordinated with the surrounding trim work, including aluminum capping, shutters, and fascia, so the finished bay window looks like a complete architectural feature rather than just a glass replacement. Specific Provia model series are not detailed in our published materials, so the best way to understand which options fit your project is to schedule a walkthrough with owner Brad Coburn.

Is financing available for dormer and bay window projects?

Yes. Exterior Siding Solutions offers 0% financing for 18 months through Synchrony. This applies to qualifying projects and is available alongside standard credit card payment. The financing option is particularly useful for larger dormer and bay window projects, which can involve aluminum capping, window replacement, copper roof accents, and coordinated soffit and fascia work all at once. Project costs across our full range of exterior services run from $5,000 to $50,000 depending on scope and materials. The 18-month interest-free period gives homeowners the flexibility to complete the full project in one phase rather than spreading it across multiple seasons.

How long has Exterior Siding Solutions been working in the St. Louis area?

Exterior Siding Solutions was founded in 1995 and has been serving the St. Louis area for 31 years. The company holds a BBB A+ rating and has been BBB accredited since 2006. Owner Brad Coburn oversees every project directly, and the three installation crews have been with the company for 12 to 22 years. That level of tenure is uncommon in the home improvement industry, where crew turnover tends to be high. For homeowners investing in dormer or bay window enhancements, this continuity means the people doing the work have completed hundreds of similar projects and bring a depth of experience that newer operations cannot match.

Which communities in St. Louis do you serve for bay window and dormer work?

Exterior Siding Solutions serves St. Louis County and St. Charles County, with a primary focus on West County communities including Ballwin, Ellisville, Chesterfield, Wildwood, and Oakville. The company's headquarters is in Ballwin, and the majority of projects are concentrated in that area and surrounding neighborhoods. St. Louis City is not a service area due to operational and logistical constraints. If you are located in one of the West County communities or in St. Charles County and are considering a dormer or bay window upgrade, the service area covers your location.

Bay Window & Dormer Installation St. Louis

Exterior Siding Solutions has been upgrading homes across West County St. Louis since 1995. Our dormer and bay window services bring real architectural character to your home's exterior, pairing premium materials with the kind of craftsmanship that comes from three dedicated crews averaging 12 to 22 years on the job. Whether you are looking to refresh an existing bay window or add definition to a dormer with metal or copper roof components, we handle every detail with the same care that has earned us a BBB A+ rating for nearly two decades.

Dormers are one of the most visible architectural features on a home, and worn or outdated trim around them can drag down the look of an otherwise well-kept property. Our dormer window installation service addresses that directly. We apply maintenance-free aluminum capping over existing wood trim, eliminating the cycle of painting and rot repair that most homeowners in Ballwin, Chesterfield, and Wildwood want to leave behind. For a truly finished look, we also install premium metal and copper roof components on dormers, giving your home the kind of detail that stands out in any West County neighborhood. Every project is supervised by owner Brad Coburn, so the quality stays consistent from the first day on site to the last.

Bay windows add depth and light to a home, but they also come with more exposed wood trim than almost any other exterior feature. That trim takes the full force of Missouri's spring hail storms, humid summers, and hard winters. Our approach as your bay window contractor is to replace that vulnerable wood with aluminum-capped trim that holds its finish for decades, no repainting required. We work with Provia windows for replacement glass units and pair every installation with properly matched soffit, fascia, and shutter work so the finished product looks intentional rather than pieced together. The result is a custom bay window that performs as well as it looks, season after season.

Choosing the right bay window or dormer contractor comes down to experience, craftsmanship, and a proven reputation. Exterior Siding Solutions has served homeowners since 1995, with installation crews that have remained with the company for 12 to 22 years. That level of continuity is uncommon in the industry and helps ensure consistent workmanship from project to project. The company is VSI-certified, holds an A+ rating with the Better Business Bureau, and has been BBB-accredited since 2006. Manufacturer warranties are available on qualifying products to help protect your investment for years to come.

Every architectural window solution we install starts with the right materials. For dormers, that means maintenance-free aluminum capping for wood trim and the option to add metal or copper roof accents that give your home a distinctly high-end finish. For bay windows, we use Provia replacement windows paired with carefully matched exterior trim and shutters. We photograph every project before and after so you can see exactly what changed, and so we can stand behind the quality of every finished job. Our work covers Ballwin, Ellisville, Chesterfield, Wildwood, Oakville, and surrounding areas in St. Louis and St. Charles counties.
