I am an Owner Operator with 39 continuous years in the construction field and 19 years in business as Vic Steiner Carpentry. Over these years as an employee of other construction companies and being self employed, I have mastered all of the trades that are involved in residential remodeling and perform all of the work myself. I will present a firm bid in a contract, including sales tax and payment schedule. Attached to the contract is a very detailed Work Specifications list that specifies every detail of the work I am bidding on. I am listed with Washington State as a certified Lead Paint Renovator and certified in Wedi tile substrate installation. Pictures of work I have done and a list of references are available on my web site at vicsteinercarpentry.com
"Vic does amazing finish work! The overall project went well and Vic worked with us to totally revamp our bathroom while helping us find the right level of customization to meet our budget. Vic was easy to work with and you can tell that he takes pride in his work. I would whole heartedly recommend Vic for any bathroom projects!"

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.
