"Brett has done two projects for me and has two projects in the works. First he installed board and batten wainscoting in my dining room totally transforming the room. Second he opened up my basement stairs taking down the wall and installing a half wall, finishing the top step to match the flooring and adding a new railing to replace the builder grade railing. He is extremely professional, takes copious notes and is a master carpenter. I love working with him. He is patient with all my crazy design ideas and changes and is a true pleasure to work with. I will keep hiring Brett until there is nothing left to change in my house. He has even worked for my neighbors who hired him after they saw the work he did in my house. He is highly recommended."

"Quality remodeling and construction provide sevice in a timely manner. I have contacted Mike 3 times for chimney removal and siding repair, decking, and to replace a chimney cap. Each time he came out within 24 hours to check things out and give me his assessment of what needs to be done. Then he let's me know when things can get taken care of and how long it will take. He has been spot on in reliability. I appreciate this diligence to providing service."

"Excellent job!! The owner ( Nick), design specialist (Neil), and project manager (Dave) were very helpful with design and material selection for the jobs. They took care of everything. All of the workers were on time, respectful of our home, and courteous. Andrew and Jim are meticulous in their work and true craftsmen! I will not hesitate to have them in my home again for any other job we may have."

"Sandiel Construction did a full remodel for us and was beyond our expectations- it turned out absolutely beautiful. Sandiel is extremely skilled and pays great attention to detail. He did our siding, demo, insulation, drywall, electrical, windows and paint - not only was it done beautifully but it was done timely. I fully recommend Sandiel Construction for your next project."

Basement Remodel FAQs, answered by experts

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

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.
