Rescuing a Basement Entrance – Structural Repair and Custom Door Modification

There is a particular satisfaction in correcting a mistake to save a piece of history— or in this case, a piece of material that would otherwise be wasted. This project was actually the very first one I completed for Beka and David, who own a beautiful home built over a century ago. It began with a frustrating situation: a previous contractor had ordered a door, left the job unfinished, and left the homeowners with a brand new unit that simply didn’t fit the opening.

The Before: A "Square Peg" in a Crumbling Hole

Beka and David were in a bind. They had a basement entry door and storm door sitting in their garage, collecting dust. The previous contractor had purchased them, but they were significantly too tall for the basement opening. The standard industry answer here is simple but wasteful: throw the door away and buy a custom-sized one.

However, upon closer inspection, the door size was only half the problem. When we looked at the threshold, the concrete looked suspect. Once I removed the old door frame, the reality of the older home was revealed: the sill plate crumbled away, and the concrete stem wall beneath it was damaged. We weren't just looking at a door install anymore; we were looking at a necessary structural intervention.

During the Build: Preservation through Precision

My goal was to save the door they had already paid for. This required a modification that most contractors avoid because it is laborious and risky.

I had to cut a significant amount off both the top and bottom of the door to make it fit. To do this without ruining the door’s structure, I performed a delicate surgery: I carefully cut the metal veneer, then mortised out the rigid foam insulation from the ends. I then salvaged the wooden rails (the internal frame) from the cut-off pieces and re-installed them into the newly sized door. This preserved the warranty-voiding structural integrity and kept the handle at a comfortable height, all while maintaining the six-panel aesthetic.

The installation itself offered the next challenge: installing a square door into a 100-year-old, out-of-square frame. Since tearing out the frame would have been cost-prohibitive, I had to rely on precise, custom mortising. I carved new pockets for the hinges, deadbolt, and latch plate into the existing jamb, ensuring they aligned perfectly with the modified door. This step is critical—if you get this wrong in an old house, the seasonal expansion of the wood will cause the door to stick or fail to latch within months.

Finally, I repaired the damaged concrete stem wall and installed a new, pressure-treated sill plate, giving the new threshold a rock-solid foundation.

The After: Security, Ventilation, and Trust

The result was a basement entrance that is now secure, significantly less drafty, and structurally sound. The addition of the glass panel storm door transformed the basement's climate control— allowing sunlight and warmth in the winter, and a cool, ventilating breeze in the summer.

This project set the tone for our working relationship. As David noted, the focus was on finding the right solution, not the most expensive one:

"Nick is just wonderful. I really like the way he communicates with me. We talk about a needed fix or installation, he gives me ideas of how it could be done, then we narrow down what is really needed and what I can afford. He really does listen to what I want, and I have never felt like he is selling me something or adding on stuff that's not needed. It's sometimes hard to find someone who is capable, creative, trustworthy, and friendly. Nick has all those qualities" — David

Thoughtful Solutions for Older Homes

This project serves as a reminder that "standard practice" isn't always the best practice. By taking the time to modify the existing door and repair the underlying concrete, we saved materials from the landfill and solved the root cause of the problem.
