Q: What are the disadvantages of a walkout basement?

• <div><p>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&rsquo;re working with a contractor who has extensive experience with this kind of basement. </p></div>

Q: Is it cheaper to build up or add a basement?

• <div><p>Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.</p></div>

Q: How hard is it to add a basement to an existing house?

• <div><p>The difficulty of adding a basement to an existing house can vary depending on the house&rsquo;s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you&rsquo;ll need to enlist professional help for this project.</p></div>

Q: Why do some old houses have a toilet in the basement?

• <div><p>Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.</p><p>Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.</p></div>

Q: How much basement wall bowing is acceptable?

• <div><p>Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.</p></div>

"It was OK. The gentleman they sent out was very nice but I think they send out different people to people who get the big deals. It took significantly longer than it should have. He had a breathing condition and it was difficult for him to do the job quickly so I don't know if I would necessarily consider that company again. I don't want to say anything bad about the company because he tried to do his best. They painted one bedroom and maybe a couple of parts in the hall. I'ts a small condo so it's not a big area. There were no additional charges. It was never an issue with the time that they came. There wasn't anything wrong with the paint job."
