With US HOME / STARS AND STRIPES has been servicing homeowners for more than 25 years. Customer preference and priorities are always first. We're very timely with our work and never lose attention to detail. Give us a call for your free estimate.Deal direct with owner. FULLY LICENSED: Suffolk County Nassau County

"Bob and his team are amazing ! They are kind and patient and can handle anything ! I was supposed to get tile flooring, but when there were complications (unrelated to them) and we had to completely change over to hardwood, their team worked with us with total ease no matter the obstacle. They give fantastic results at very reasonable prices. But more important (in my opinion) is how they really are just good people. For example, after dropping off my keys to the guys so they could start the hardwood flooring, I was driving to work and pulled over for a deceased animal. I was on the phone trying to figure out the best course of action when Bob walks up to me ! He also just pulled over to help the animal before even realizing his customer was the person next to it. Bob took over and brought the animal to a local animal hospital to be checked for a microchip and cremated. Actually so wild how positive of an experience I had in even the most stressful times thanks to Bob and his team. If you guys are reading this, thank you so much !!!!!!!"

Full service remodeling, roofing and siding contractors serving Long Island. Whether you are in need of new roof installation, roof restoration, or roof repairs; new siding installation, siding repairs; new windows & doors installation; kitchen remodeling; bathroom remodeling; we are the Long Island home remodeling contractors to call, due to our professionalism and affordability.

"The initial meeting with John was promising. He was straightforward, easy to talk to, and quickly provided a quote without being pushy. I appreciated that he offered light recommendations without trying to upsell us. After that first meeting, I felt comfortable moving forward. I had John come out one more time so my boyfriend could meet him, ask a few more questions, and finalize the siding and color choices. The next morning, John texted early, saying he’d be by within the hour to pick up the $10,000 deposit. We were told materials would be ordered right away and the project would begin by the end of the month. However, as that date approached, we hadn’t heard anything. When we reached out, we were told it would be delayed by another week — and then again, another week. We were okay with some delays, but the complete lack of communication was extremely frustrating, especially since we needed to coordinate our work schedules. We were also told the work wouldn’t involve anything on the inside, but that turned out not to be true — which was a big issue since we have two pets. During the project, our flower beds and garden were completely destroyed. While some wear and tear is expected, there was no reason for a large boxwood bush to be crushed with a cinder block when there was clearly space to work around it. Several things were damaged, including blinds, window sills, a shelf, and part of the entrance flooring. While I understand that accidents happen during construction, what bothered us most was the lack of accountability. None of these issues were addressed until we specifically called them back out to deal with them. John never showed up for a single walkthrough, and to our surprise, the entire job was done by a different company altogether — not his own crew. That was something we hadn't anticipated, and unfortunately, we didn’t think to confirm it beforehand again our fault. The windows installed were low quality and very off-brand compared to what we expected. We had also discussed having decorative grills/grid lines in the windows, which were completely left out. In the end, while everything listed in the contract was technically delivered, the overall experience left a lot to be desired. The workmanship felt sloppy, communication was almost nonexistent, and the lack of oversight from the owner was disappointing. We definitely feel we overpaid for what we received. It’s partly on us for not being more proactive during the process, but someone who takes pride in their business would have at least done one final inspection or walkthrough."

Our mission is to service our customers in a prompt and professional manner. We do not consider a home improvement or remodeling project complete until the work is finished, the job site is clean, and the customer is completely satisfied. Licensed & Insured since 1997

"This is an overdue review. I hired Bernie and his team for a kitchen remodel in June 2021, after he did an excellent job with my three bathrooms in 2020. The kitchen remodel was also excellent. His works are efficient, hardworking and clean. My remodel took two weeks, as he had quoted and for the exact price he had quoted. I would hire him and his team again and I referred them to a coworker for her bathroom project. She was also very pleased with their work."

FAQs for foundation drain installation projects in Valley Stream, NY

The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end. 

For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
