"I had an excellent experience with SZ Home Construction?. They completed the chimney maintenance, cleaning, and painting professionally and at a very reasonable price. The work was finished on time, and the quality exceeded my expectations. What impressed me the most was their attention to detail and respect for cleanliness ? they cleaned the entire area thoroughly after finishing the job, leaving everything neat and organized. Their team was polite, calm, and very easy to deal with. They worked smoothly and quietly without creating unnecessary noise or disturbance, which made the whole experience comfortable and stress-free. I also appreciated their professional and legal payment process through bank checks, which added an extra level of trust and reliability. I highly recommend SZ Home Construction? to anyone looking for honest, professional, and high-quality home service work."

"I needed complete drywall replacement in my garage, ceiling and walls. I did not know Southside Builders prior to hiring them for this project. The owner, Neil Dylag, showed up for the initial evaluation when he said he would. He provided a timely estimate. We agreed to a start date and estimated completion date. This project started and finished as scheduled with no additional charges or change orders. His solutions to the couple of glitches we had were sound and better than my recommendations. I found Neil to be an extremely hard working and honest businessman. I'm satisfied with the job and recommend him to your project."

Basement Remodel FAQs, answered by experts

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. 

While bathrooms and kitchens are nearly equal in terms of renovation difficulty, kitchens are the most challenging. Kitchen design, layout, electrical, and plumbing needs all depend on each other for the success of the entire project, and mistakes early in the project can cause trouble later on.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.
