Small jobs welcome

"I've got a 112 year old hose that is pretty solid, but it had a cracked floor joist and part of the flooring wasn't properly supported. I hired Kristian and his team to install a couple of lally columns to support a carrying beam and sister a couple of floor joists. Many contractors wouldn't even return my call because I wasn't looking to complete a huge remodel job, but Kristian came over, gave me a fair verbal estimate on the spot, and worked with me on timing to complete the project. Not only that, but the solution wasn't overly complicated. The job was straightforward, completed exactly as described in the time described, and there was no scope creep. If I ever have a larger need, they'll certainly be my first call. I would highly recommend K&X construction if you need any services that they offer."

Customers say: Quick response

"The carpenter that did the job (Adam) was amazing. He had to expand the space for one window, narrow the space for another, and repair much cedar siding that had rotted away due to water damage. He also reshaped my patio door so it would close and lock more easily. He is a very talented carpenter and I have no qualms about highly recommending him."

"I called them and left a message about what I needed done. I received a call from them the same day. They were Abel to come the second day. The job of installing a gable vent on my house was done in less than 2 hours. I will definitely use them for my next project."

Basement Remodel FAQs, answered by experts

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.
