"John Bridgman and his team did an excellent job plus they were so good at keeping on task and communicating with us. He texted the times they would be there and followed through. The workmen were very courteous and pleasant to deal with. Work was promised in 3-4 weeks and he was done exactly after 3 weeks - and they did a complete re-do of our bathroom. I would definitely hire them again."

Addition and remodeling services FAQs

Due to the additional excavation and structural work required, walkout basements cost more than standard below-grade basements. Creating a ground-level entrance involves specialized foundation cutting, waterproofing, and often retaining walls to manage the excavated area. These extra requirements add to the overall expense compared to a conventional basement, though costs may be comparable if your property already has a suitable natural slope.

Installing a walkout basement door costs between $230 and $5,000, depending primarily on door type and installation complexity. Standard single exterior doors fall at the lower end of this range, while sliding glass doors or French doors with extensive foundation modifications cost significantly more. The price includes cutting through the foundation wall, framing, installing the door unit, and ensuring proper drainage and waterproofing around the entrance.

Converting a standard basement to a walkout basement falls within the overall project range of $5,000 to $35,000, depending on your existing conditions and desired features. Major factors affecting conversion costs include the amount of excavation needed, foundation modifications required, drainage solutions, and any finishing work. Properties with natural slopes require less excavation, potentially reducing overall costs.

A walkout basement offers several advantages over a standard basement, including direct outdoor access without navigating stairs, abundant natural light through full-sized windows and doors, and improved air circulation. The space feels more like a main-floor living area than a basement, making it ideal for bedrooms, entertainment spaces, or home offices. Additionally, the separate entrance creates flexibility for rental units or multi-generational living arrangements that standard basements cannot easily accommodate.
