How do I get rid of Cold Air and Mice in my Basement?

Joseph Coupal - Wednesday, November 21, 2018

Winter is fast approaching and we are starting to get calls from homeowners with stone foundations about cold air and mice in the basement. The typical issue there is that these stone foundations are pretty old, usually 80 to 100 years old. Mortar, kind of like the glue, is what holds these stones together. Well, if we were that old, we'd get a little decrepit and so does the mortar in between the stones. When that mortar ages it crumbles and you'll see a white powdery material on the floor; or if you drag your finger on the mortar it crumbles or has already crumbled. Once it crumbles it creates voids which allows in cold air. Think about all the stones in a stone foundation and the amount of mortar that can crumble. That's not like having a window open, it is probably more like having a sliding door wide open letting in cold air. But, it's not only letting cold air in, it can also let in furry friends like mice and rats, and even snakes.

To fix a stone foundation, we go in there and take out the mortar that has crumbled, is loose, or is non-existent. Then we put that mortar back in. This is called re-pointing a foundation. Right now in MA, RI and CT we are getting a lot of calls for this.

Why Does My Concrete Look So Rough and Pitted? Boston, MA

Joseph Coupal - Tuesday, November 13, 2018

We take good care of concrete. Concrete can start to look rough and pitted, we see this in New England all the time. This happens because water penetrates the concrete because concrete is porous. When the water penetrates, and then the concrete freezes, it can pop some of the concrete a little bit. That's when you see that rough spalling going on. We also use salts or materials that melt the ice, and the water penetrates the concrete and freezes again. We see this quite often. Spalling is concrete that absorbs some of the moisture, freezes, and then it basically pops, breaks, and chips off.

To fix it, we have to get any concrete off that is loose or not solid. We clean it out and then put in what we call a "milk," which is an adhesive. Then we put some specialty masonry material back on it. I then recommend spraying it with a crystallized quartz based material that goes into the pores of the concrete. We don't only spay it on the space we repaired, but also on the steps or on the side of the foundation, or in the garage on the sides. This does not let the water penetrate.

We can fix this concrete that does not look so great and get it back in great condition. If you have basement water proofing issues, contact A1 Foundation Crack Repair.
