"The job was done perfectly! The contractor was very professional and had great attention to details. I could discuss with him a few different options and pros and cons of each. He was showing on time everyday and working very hard. Finished project looked exactly as I wanted it. The only minor problem (hot/cold water pipes connected to opposite ends) was fixed next day after reporting it."

"Gil did an amazing job of figuring out exactly what I needed, and he hired an amazing crew to get it done. This is by far the best home renovation experience I've ever had. Gil and Oliver both were very thorough in figuring out what needed to be done, and every step of the way if there was ever any ambiguity, they asked questions and came up with great solutions for everything that came up. I have never before had such a good experience with a home renovation, and I wish all contractors were as good as them. My project was fairly involved, with a complete renovation of my kitchen, dining room, and laundry room, and yet the whole process took under a month to get done, and it was done right the first time. I wholeheartedly recommend Your Home Builders. No complaints at all."

Basement Remodel questions, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.
