"Very well. It started with the estimate visit by Ron. Unlike other contractors, he showed me just the necessary amount of work. For example, others told me my lally columns would need to be replaced and he showed me that the rust was superficial. That saved me hundreds of dollars. When they got there on time, the crew was obviously experienced and worked well with me and with each other. They worked efficiently, were very nice and cleaned up after themselves - inside and outside. They did little extras for me such as prying up a specialty floor tile to preserve it and fill in a channel which had been cut into the basement floor previously. I felt no hesitation to ask questions, which is kind of rare in work crews. They said the job would take 2 days and it took about 1.5 days. Another extra was I needed 2 new basement windows. 3 had been replaced previously and Ron took the time to order identical windows so all 5 windows would match. That was nice. All this for a reasonable price. I highly recommend B-Sure!"

"The owner, Stan Howard, is a very nice guy and very responsive to questions and needs. He has a full-time crew and the same guys showed up every day on the job. Took about six days to complete, but probably could have been less if the weather had cooperated. One day the crew left early because they were getting hailed on! They came down the ladders with hailstones in their tool belts, but they had still worked for quite a while in to make sure the unfinished parts of the roof were covered and protected. The crew was very pleasant and knew what they were doing. We have a very steep roof slope on parts of our house, so it was always a worry that I would see a roofer fall past a window -- but they didn't have any problems, from what I could tell. Our new architectural shingles are very rich-looking, and they really enhance the appearance of the house. Our gutters are the kind that are supposed to be fastened with straps around them to the roof, but I thought that was ugly and asked if we could have them fastened differently to avoid the straps. They accommodated my request and we now have nicer-looking gutters than before. They removed the old roof vents and installed a ridge vent. We also asked them to install a vent for our new bathroom fan, which they also did. We had a couple of questions/minor adjustments to the gutters that we wanted done, so we called them a week or two after the job was completed, and they were here within a few days to make the requested adjustments. All in all, a very solid job! We are planning on getting in touch with them again in the fall for window replacement."

"The crew arrived and started the work at the time agreed. When the old roofing was almost removed, the foreman of the crew, Dave Cook, approached me to show the condition of the old roof base. I knew that we may have to address that after years of small leaks that had occurred. Dave told me what my options were and how they would affect the long term results and we decided to lay down a new decking over the existing one. I was promptly quoted a price and put in touch with Becca at the office to authorize the Change Order. I had to leave for work after that feeling the I was in good hands. When I came home from work the new decking was almost completely installed and the base layer was soon to follow. I saw how careful the base layer was rolled out to eliminate any creases. It was getting late and the forecast was for rain to come in later that night. Dave told me that they would stay until either finished or at least the roof would be flashed and water tight. When it got dark, we found some headlights for the guys to were so that they could see well enough. The roof was made water tight with one bit of roofing to be adhered. There was not enough flashing in the trailer to finish without a seam and Dave wanted to finish it with a single piece. I agreed. The weather turned to rain and clod for the next week and was not able to finish until the following wee. During that time either Dave or Becca would contact me every day to let me know what the plans were so that I was not in the dark. I really appreciated that. Overall my wife and I are very please with the professionalism, quality of work, cleanup, and communication. We will definitely use them again and recommend the to anyone."

"We used this company to replace a roof on both of our homes; both ashpalt and metal. The work was always superb, and their attention to detail was always impressive. The whole crew was always kind and courteous, and a joy to have working on my house. It was wonderful having such a trustworthy company working on the project because I could go about my life and not have to stay home while they worked. I would hire them for any of my remodeling needs."

"This is a great company to work with. Our project involved tricky design and construction issues and was complicated by the fact that there were certain elements that we were determined not to change. Upscale worked with us to develop a vision and a specific plan - from the major elements down to the trim - and implemented it beautifully. There were a few problems with subcontractors and we were so appreciative that Upscale held them to account for high quality work -- we did not have to complain, Upscale insisted that the work be done right. For high quality, detail and service oriented work we wholeheartedly recommend Upscale Remodeling!"

"10 of 10. Dan Brown's crew was professional, curtius, on time and detailed oriented. There work was perfect. They showed up the the day they said they would, and worked everyday until the job was completed. They cleaned up the job site and went above and beyond to make sure the job was done to my satisfaction. Owning a local business and having experience in building, it's hard to impress me, I was very impressed. I highly recommend Dan Brown Construction for any of your remodeling, roofing, siding or construction needs. Dan's excellent communication, fair prices, down to earth personality, and professional detailed workmanship makes him the right person for any small or large job. We are already excited about hiring him for our next project this coming spring, a new deck."

FAQs for basement remodeling projects in Cortland, NY

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
