"Remodeling our kitchen was an interesting experience and we were very happy with the result. Since first day Jess was very helpful and transparent with the information we needed and was always available for any question we might had. He and his team did everything to make the experience as smooth and efficient as possible. It only took 2 weeks to complete the remodeling and they were very professional and always on time with the schedule."

"I HAVE USED JOE BOYER'S CO. ON NUMEROUS REMODEL PROJECTS. JOE'S CO. IS TOP SHELF FROM START TO FINISH. HIS WORK IS VERY PROFESSIONAL. HE IS GREAT TO WORK WITH.

I KNOW JOE'S WORK ETHICS AND I HAVE NO PROBLEM GIVING JOE HIGH MARKS FOR HIS PROFESSIONALISM. UNFORTUNATELY, I MOVED ACROSS COUNTRY AND NO LONGER HAVE ACCESS TO JOE BOYER'S SERVICES."

"Oleg and Omkal Construction did an amazing job on our remodel and repair work. Shortly after settling on our home we found major termite damage. Oleg and team removed the damaged joists, took down a wall and installed a new I-Beam giving them a an amazing open floor plan with which to do our remodel. Oleg is responsive, timely and does great work. I would not hesitate to use him again!"

"Emaintenance company was so helpful in making our home remodeling stress free. They painted our home from top to the bottom ( ceiling, walls, baseboards). The owner of this company is very nice. He totally worked unsupervised while we were in Virginia. He suggested colors for our walls, it looks amazing. They did such a wonderful job with our home. It is so nice to find people with exceptional work ethics and experience. We highly recommend them for high-end projects you may have."

Basement Remodel FAQs, answered by experts

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.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

Home improvements that increase value offer a high return on investment (ROI) and can enhance your quality of life. Upgrades to your home’s curb appeal often add the most value, with garage door replacement having one of the best ROIs at 93%. Other high-value exterior projects include replacing your front door, upgrading siding and roofing, installing a stone veneer, adding new windows, and landscaping. For interior renovations, a fresh coat of paint provides an excellent ROI. Major projects like a kitchen remodel or upgrading appliances and HVAC systems also add significant value, as potential buyers appreciate the peace of mind that new equipment provides.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

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.
