"Plow and Property has completed several projects for us on a very old and neglected rental property and we are so glad we found them. The first job was a vacant house clean out. The house was left in truly appalling condition. The cleaning crew worked and worked and worked so hard and so long I was telling them to stop. They made a filthy house fresh and pleasant again. I would not have thought it could be restored to such a fresh condition. The next job was replacing the old casement windows which were rotted wood frames in crumbly 1950â s cement. They not only repaired the window foundation area but other foundation ugly spots as well and put in beautiful new sturdy basement sliding windows. They also re-dug and replaced the adjoining window wells which were undoubtedly the original wells and were falling apart. Regraded the foundation area around the wells and reseeded without being asked. While they were in the basement doing the windows they cleaned a bunch of that up too so itâ s no longer a horror movie waiting to be filmed down there. Everything they did was simply above and beyond. Wesley Vercosa has returned my many questions and concerns with lots of information and smiles, bless him. My retired husband worked in construction for many years and he is happy and impressed with the work. We are planning more work with them already."

Basement Remodel questions, answered by experts

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

The difficulty of adding a basement to an existing house can vary depending on the house’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’ll need to enlist professional help for this project.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

Yes, finishing a basement is worth the money in most cases. Although the project is a relatively expensive one, finishing a basement adds usable square footage to your home and typically increases your home value. Many times, your finished basement will add value that’s equal to or greater than the cost of finishing.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.
