"A huge thank you to Bryce Edlund from Foundation Systems of Michigan (FSM)!

"Troy and his team were so wonderful throughout this entire process! Troy came out over a year ago to quote - he spent nearly 4 hours on my property making sure that he understood exactly what was going on with each of my buildings. He took several pictures and gave a very estimate. I had several other companies come out to provide quotes & they just simply weren't as thorough or kind. Troy continued to follow up and once we were able to budget for the project, he came out and made sure nothing had changed. Throughout the job he took TONS of pictures so I didn't have to go under the building to check it out. They were professional & very respectful of our business operations. I will have them back this summer to finish up some additional projects! HIGHLY RECOMMEND THIS COMPANY!"

Locally owned company, with owners that have over 30 years of experience in the industry. Specializes in doors, windows, siding, and roofing. Products sold by Markin Co are environmentally friendly and innovative.
"Our sliding door was ordered and installed on time with appropriate correspondence. The installers were nice but attempted to leave the job without ensuring that the door was squared and closed completely. When I pointed this out to them in the driveway, they came back and addressed the issue. Later in the evening I noticed that an weather seal inside the door was clearly damaged (visible by rips and tears in a black seal showing white insulation beneath) in a way not possible by use. I called the company on numerous occasions, sent numerous emails with photos of the issue starting on the day of installation and now, four months later, I have only received follow-up calls from the company when they're canceling an appointment to repair the issue and have never received a follow-up call on how they will address the issue. The door and installation was paid in cash. I would seriously reconsider using Markin for any large job as this was just one door and I've been waiting four months now."

"I hired JLM Home Solutions to install all my interior doors and closets including frames/casings in my upstairs. Jason was a horrible person the entire time I hired him. He acted like a nice person just to get hired. I regret hiring him. Unfortunately I had signed a contract by the time I found out he was no good. Every time I brought up something that was not done right, he’d yell and raise his voice at me. He’s very rude and unprofessional with the worst customer service. He was rude on text, rude on phone and rude in person. Jared, I guess one of his employees was a great person, very polite and did an amazing job. He worked on the project in a professional manner. He didn’t come back though to finish the project because Jason sent another person instead, David, who did an awful job. Jason didn’t want to hear it that David’s work was not the greatest. I had to put a stop payment after I found out one of the closet doors wasn’t installed right and other things that were wrong. Jason got so upset that he had to come back to fix the problem after I told him I didn’t want David. Jason came to my house but failed to fix the problem still. Instead he made me feel threatened in my own house. He was all in my face yelling at me saying nothing was wrong with the closet. Even my little dog was scared. I had to call my daughter and son to come over because I was so terrified that he was maybe going to hurt me. I stayed on the phone all the time while he was there so someone could hear his abusive behavior. That day after Jason left, I had to get a second opinion on the closet. Another contractor couldn’t believe the way the closet was installed and for Jason to insist it was okay. He left the old frame on and didn’t want to here when I mentioned it. I’ll have this closet removed and a new one with new frame installed the right way. I had to insist Jason deduct some money for that closet from the balance owed to him. A couple of days later, I noticed my kitchen door they installed still had cracks on the inside frame close to the lock. I had mentioned that to him. I texted him to let him know with pictures showing the cracks. Now Jason won’t respond to my text, email or phone. I asked him to send one of his guys to fix the door. Not him because I don’t want him around me. I’ve tried everything to get to him. I know he’s ignoring me. I paid him so much money for this project. If I don’t hear from him I’ll have no choice but to file small claims. He cannot leave my door like that after I paid him so much money and thinks he can just get away with it. If there was an option of zero stars, that’s what I’d have given JLM."

Basement leak repair services FAQs
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.
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.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
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.
