"Kaydn has been very responsive as our renovation and repair needs evolve. We certainly aren’t done yet, but we will keep this company involved as we continue to work forward through some major renovations. We just started with them for essential repairs before embarking on the more ambitious projects. Kaydn has proven himself as very knowledgeable and capable. More to come."

"Don and his assistant Clay did a great job installing interior closet doors and a stair railing in my home. They were great to work with from start to finish and I highly recommend them."

"What I found outstanding was the excellent communication from Greg about my project at all stages, from the first meeting, through the repair process, to the completion. I always knew what to expect from the day-to-day work and I felt he and I were on the same page. My facia board, gable board, removal of moss on my roof and door replacement was accomplished safely and thoughtfully by his competent crew. I would recommend this company to anyone as I feel they are very trustworthy, and I hope to use them again for my next project"

"They did a good job especially considering how brittle my old siding had become over the years. I’m pleased with their work and the price was right. I plan to hire them to do a couple more small jobs that I’m to old to do myself."

Basement Remodel FAQs, answered by experts

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.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

You should always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.

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.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.
