My buyer Theo wins the award for the single most expensive repair I have negotiated for a buyer. Theo was a first time buyer who was referred to me by a past client of mine who they work with. We met up on a chilly fall evening to talk about what they were looking for in a house and get the process started. Within a couple of days, Theo had their pre-approval letter in hand and we were ready to go. I sent them all of the available homes within the geographic boundaries, price range and features they were looking for. The list wasn’t very long and out of all of them, only 2 houses piqued their interest. We went to see one in NE, and that was a no-go. The second house we saw was bright blue 1920’s bungalow in the Brooklyn neighborhood. It had been on the market for about a month and had one sale fail. The home was lovely with a gigantic newly remodeled kitchen and a large upstairs bedroom with room to add a bathroom. The basement was decent enough with lots of windows and good ceiling height- a great candidate for future finishing. Theo slept on it and the next morning let me know they wanted to write on it. We put together a great offer and boom- got it accepted.
Most of the systems had been upgraded so I wasn’t too worried about the inspection. However, during the inspection our inspector did a few pokes at the foundation walls and the foundation just crumbled into sand. In the 1920’s during the huge housing building boom there were two concrete companies operating in Portland and those two companies provided all of the concrete for house foundations built during that time. One company had a better concrete formula and many of those foundations are still in reasonable shape. But the second company didn’t quite know how to mix concrete very well, and those foundations are showing their age as they reach the end of their useful life as seen in the crumbling foundation walls. This basement had been skim coated on the interior at some point, but in areas like behind a built in workshop and under the stairs, the tell tale signs of a rapidly deteriorating foundation were all there. For most buyers, that would have been the end of that and they would have terminated. But Theo really loved the house and location, so they took the next step and hired a structural engineer to come out to take a look so they could make a decision to either move forward with the transaction or terminate. I had a great conversation with the listing agent about the issue, and thankfully the sellers understood this wasn’t a repair they could put off if they wanted to sell the home. Thankfully the engineer was able to come out and made the determination that the foundation really was on its last legs. She told us there were 2 ways to approach a new foundation- one way was to lift the house and pour a brand new concrete foundation. This route is prohibitively expensive- costing in the $80k-$100k range. The other option is to have an engineered wood wall built. With this method, an engineer designs a wood wall that is built in the basement up against the old concrete foundation and embedded in a new interior concrete footing and attached to the framing of the house. As long as the engineered wood walls are kept dry, which involves rubber matting between the old concrete foundation and the new wood one and making sure the drainage system around the home is effectively channeling water away from the house, the new wood foundation can last indefinitely. And because it’s wood, it has give so also provides better seismic protection than old concrete foundations. The old concrete foundation stays in place, but it no longer functions as a support for the house. And the new foundation gives the basement an almost finished look.
We wound up doing 5 inspection extensions to get the engineer to have the drawings ready before closing, and to get a firm bid from a contractor to do the work after closing. Closing was delayed by 10 days- but we did it! Due to the whole supply chain, dearth of availability of contractors, etc., the work can’t be done for a while, but that’s ok because the contractor has already been paid and stated that they will complete the repair within the next year for the stated bid amount. The cost for something like this obviously depends on the total linear feet and some other factors, but in general, this type of repair will cost in the $35,000-$60,000 including drainage, which is a whole lot of money, but about half of what it would cost to replace the foundation with concrete.
