Basement wall repair

Our house was built around 1920, and has old cement walls that are about 3 - 4 feet thick in places and are only about 6 feet high. Is it possible to have them replaced with narrower ones? Also, is it possible to have the basement ceiling raised?

Hello,

If your cement walls are of LBW type, means load beading walls, then it must be examined thoroughly since it's very old. If it's load beating, then I don't making them thinner, only if replaced with new reinforced but thinner walls. As for the basement slab, yes it can be done, but it's a costly procedure.

Not really my area of expertise but.....

This is a very expensive proposition. Replacing a foundation is critically expensive. I highly doubt that you would recover any more than maybe 25% of the cost in resale value.

As far as height, you can either underpin or bench the basement walls and lower the floor. This too is an expensive undertaking and will undoubtedly uncover some other issues that will also need to be rectified. It probably wouldn't cost too much more to just demo house and start new compared to the cost of the jobs in your question.

Hi Denise,

It sounds like you want a new foundation. There are two ways to get more height in the basement.

1. Remove the slab and underpin the foundation. This is less cost but you will end up with thicker walls

2. Raise the house and build all new foundations. This is more efficient but a lot more costly. You will end up with standard 8" thick walls all around

Budget $20,000 to $40,000 for option 1, $80,000 to $120,000 for option 2.
