"We had three companies call us back. Company 1 met with us to discuss our wishes and drew a rough sketch of the proposed work. They said they would work up a more detailed drawing and e-mail it to us for review. A few days later the sales rep sent a text asking if we had a chance to look at his proposal. I said we never received the drawing and perhaps it was sent to the wrong e-mail address. I confirmed my e-mail address and was told that he would correct and resend. I never heard back from them. Company 2 met with us to discuss our wishes. We ended the meeting with the expectation that they would send me a formal proposal. I never heard from them at all so they were even less responsive than Company 1. Fortunately Universal Unlimited called us also. Universal Unlimited (Hector Marmol the owner) wasn't the first to respond to our project request but his was the most responsive. We set up a meeting. Hector Marmol (the owner) listened to our wants and used his PC to create a rendering of the proposed deck based on our talking points. We also inquired about PVC fencing for a future date. Hector gave us a very attractive price for a bundled package of decking and fencing. We accepted although I was a little hesitant because most of his reviews were for fencing. I'm glad we made the decision since the final results were exceptional. Props to Jose Salguero who did most of the work."

Basement Remodel questions, answered by experts

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

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.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

Finishing your basement adds value to your home, providing an average return on investment (ROI) of around 75%. That means the typical basement refinishing costs of $32,000 will add an average of $24,000 to the value of your property. The value added to your home will depend on the price you pay to have the work completed, the area you live in, the quality of the work and building materials, and more.
