Q: Can you add a bathroom to an unfinished basement?

• <div><p>Yes, you can add a bathroom to an unfinished basement, but you&rsquo;ll want to take proper precautions if doing so. As with any bathroom addition, you&rsquo;ll need to make sure that it&rsquo;s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.</p></div>

Q: What material do you use to waterproof a basement?

• <div><p>&ldquo;Basement waterproofing&rdquo; sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.</p></div>

Q: What is the best basement ventilation system?

• <div><p>The best type of basement ventilation system depends on your budget, the moisture in your basement&rsquo;s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.</p></div>

Q: Is a vapor barrier required in a crawl space?

• <div><p>In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture.

We had an Angie's List coupon for a basement inspection. They scheduled instantly, came on time and were very professional and helpful. We decided not to pursue putting in a large humidifier, but if we were to undertake any waterproofing, we would probably call them in first.
