CWE Renovations is ready to turn your project into a reality - no dream is out of reach! Our team of expert remodelers will give a thorough assessment & estimate for your project. Call today to get on our schedule!

"Our experience with CWE Renovations has been marked by a troubling lack of professionalism, accountability, and customer service. Despite having a comprehensive record of issues spanning nine pages, we will have to summarize the key points here to provide a clear picture of why we strongly advise against using this contractor. Project Timeline and Delays: We were initially given an estimated completion timeline of approximately 12 weeks for our basement renovation. Contrary to this, the project has now extended well beyond 18 weeks. We were assured on two separate occasions (6/27 and 7/11) that only two weeks of work remained. Unfortunately, scheduling has been disorganized, with no clear plan to ensure tasks are completed consecutively. For instance, the electrician's work remains pending with no definitive schedule, and the carpet installation, scheduled for August 19th, was delayed due to the contractor's failure to arrange for measurement until July 26th (despite us inquiring about this since 6/27). Communication and Accountability Issues: Our attempts to gather accurate information and resolve issues have gone ignored. We discovered discrepancies when we contacted Waste Management regarding the pickup of our bagsters, only to find no record of an order. Additionally, a metal rack has been left for 2.5 weeks in our driveway due to the contractor's failure to follow up with Home Depot immediately upon it being left behind by mistake. More concerning, we found that the electrician listed on our permit had no involvement with our project. Upon investigation, we learned that the permit was improperly filed under a business' name, and the electrician ,who worked for the business, was only working on our project as a side job, potentially jeopardizing their professional standing. Overall Experience: The most disappointing aspect has been the lack of communication and ownership. We are left with an incomplete basement and are now seeking a refund for the portions of the project that have not been completed as promised. Given these significant issues, we strongly recommend avoiding CWE Renovations for any renovation projects. Our experience underscores serious concerns regarding their reliability and commitment to customer satisfaction. Everything incomplete as 8/12 (18 weeks after the start date with a 12 week estimate): Electrician to finish outlets, lights, light switches, etc (no eta) â we paid for on 7/30 Carpet Installed (given a date of 8/19 which is completely unacceptable when we have been asking about this since 6/27) we paid for on 7/30 requesting this refunded since Carpet Installation Guy does not want to work with Dan and quoted us almost half to install Trim completed around stairs and in bathroom - Paid Metal Rack Removed from Doors (Offered to reach out myself since Dan doesn't seem to have any urgency in it) -Requesting Dan cover the cost to remove on 8/15 Garbage Removed (two bagsters) We paid for on 2/26 Door Installed over the breaker box Lien Waivers from Plumber, HVAC, Electrician Railing on the stairs (which we have made clear we do not want this in until carpet is installed so we can get our couch downstairs) Paid on 4/12 invoice"

"When Mike came out to give me a quote, he told and told me he would get back to me in a week and could probably finish part of the work in the next two weeks and start the full remodel within a month. That was in January, and I'm writing this review at the end of March. I called him several times and finally caught up with him about a month ago, when he said he had had some family issues and would get back to me soon. But he never did. I spent time cleaning my house, speaking with him, writing him an email with all the details of my project, calling references, and waiting months for an answer. The very least he could have done was said he wasn't interested in the project."

Basement remodels FAQs

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.

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.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

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.
