"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."

"We interviewed four companies for our project. Hilltop Remodeling wasn't the most expensive or the least expensive. Bill, the owner, is very personable and we liked him right off. He and his crew are very professional and completed the job in a timely manner. They removed a tub in our sons' bathroom. They expanded, built, plumbed, and tiled a new shower stall. Hilltop also re-grouted our tile and painted the bathroom and our son's bedroom. We are very happy with the results and would rehire Hilltop Remodeling again."

Basement Remodel questions, answered by experts

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote.
