"Opportunity Construction will always be my #1 company to go to for my fencing needs. Here's the reason why. First, from start to finish, Dean Currow was very knowledgeable about installation of fencing. He displayed great customer service, professionalism, attention to details, and was so easy to work with. He was prompt; arriving on time each day. Second, his team of workers were exceptional! They were the best; working hard...non stop, until the last steel panel was in place. Opportunity Construction made my dream come true. They are an A++++ company. Last, I couldn't be happier with the installation. The fence looks beautiful, and from all of the drive-bys, I am sure this company will be receiving a few more calls."

"If I could do minus on the stars I would give a -5 stars. This company is horrible and Skylar Jump is rude beyond beleif. He came out and did the bid for the job, and he told me what it would cost me. 1/2 down and the other 1/2 upon completion of the job. They installed new drywall but did not make it flush at the corners, leaving big gaps and putting in large gouges. He and his crew left garbage all over the yard, stole materials and left my house compromised and exposed to the elements. Also damaged some of my vintage furniture from the Hoquiam Castle. So no replacing those. He was calling me and his crew inappropriate names and telling me that I don't listen, constantly interrupting me and told me that my family member who is an expert in siding doesn't know anything and started dising people. Also will not give you a receipt for money paid and will not give you a break down of the job. Also, when picking up materials from Home Depot, he will charge materials for another job onto your account. Do not hire this company unless you want to punish yourself and lose your money."

FAQs for basement remodel projects in Cosmopolis, WA

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.
