"He did a beautiful job, I paid for the materials, and he did a good job with the repairs. Major repairs was done on the boards that was done in 2011, and some was not installed properly, he came back to fix the boards up he was able to re-fixed the boards properly. He was able to provide additional works for me, thoughtful and considered my needs. One concern I had with the work was that things were not plumb and squared."

"We called Mr. Marku about repairing a home attached shed that had seen better days. He quickly came out and discussed the project with us, took a few photographs and let us know how much the project would be. After my wife and I talked, we agreed this was a very fair price. A week later, Mr. Marku and his wife started on the project. At the end of the first day, we knew we had made a great decision on hiring Marku Construction. Throughout the 3 days they worked, they always provided excellent communication of how the project was going and what the next steps would be. They kept the work area clean when they left at the end of the day and put the small amount of debris out to the street. When the project was complete, we couldn’t believe our eyes. The ramshackle shed that was an embarrassment was now something we could be proud off. The job Marku did with the framing, siding, doors and painting made the shed a structure that can withstand the next 20 years and complement the rest of our home. My wife and I would hire Marku Construction again."

Basement Remodel FAQs, answered by experts

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

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.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.
