"Signed contract on May 8 for deck build.On May 12 rep came to my office to collect deposit of apprx $13,000. He said project team meeting on Wed & would update me then on start date etc. On Fri May 16 I had to reach out to him. He wrote the team had met & materials were ordered. An hour later he wrote back that he was misinformed & that his boss was going to call me next week. Despite this, dep check cashed. On Mon 5. 20 rep wrote back that they had forgotten certain costs & to proceed it would be $8,000 more. Not a typo. $8,000 more. No apology. Ridiculous, contract rescinded. I wrote that he could return my deposit at my office just as he had collected it. On Wednesday the 21st I got a text from "Tom," presumably the owner/boss, saying he would "drop a check in the mail" to my address. Today is May 30th, Friday, and still no check. Check at a minimum should have been overnighted. They owe me interest not to mention the deposit to hire a contractor who will honor contract. Bad."

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

Mavridis Contracting Services, Inc fully licensed and insured company has been in business for over 20 years servicing all your home improvements and general contracting needs. We specialize in all aspects of home remodeling, additions and decks. We provide craftmanship work, attention to detail and professionalism.

"I wanted a shower expanded. George Mavridis's estimate was very competitive but I hired him because I knew he was honest, quality focused and an open communicator. He has a small crew and excellent subs so he's not super fast. But Mavridis is excellent. One example: The shower needed a new fan, vented through the attic roof. The attic boards were all cut (before my time) in half when insulation was installed. The attic floor was unstable and unsafe. George was very busy but he had his team replace the boards with plywood panels...for 20% less than I expected. Why? Because he wanted to make sure I would be happy when the job was done. I could give 4-5 other examples but you get the point. If you hire George, you'll be pleased."

Big praises also to Mariano and Neto, who did the carpentry work, glass shower installation, among other tasks.

"Joe and his team did an incredible job, the work was excellent and I appreciated the workmanship and the creative trouble-shooting (it's an old house!) to get excellent results. Everyone on his team was great: skilled, hard-working, friendly, and kind/respectful. Pricing was very reasonable and allowed me to upgrade items like appliances without sacrificing the scope of the remodel, quality, or workmanship. My house is transformed and I could not be happier with the results."

Basement Remodel questions, answered by experts

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.

You should always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.
