"PAR Construction is the gold standard in my view, and I cannot recommend their services highly enough. To quickly summarize - I hired PAR construction, and you should too! PAR Construction transformed a confusing and inefficient floor layout in our 100-year-old house into a beautiful space that makes sense for our family. They completed the project on a reasonable timeline, despite a week of no electricity (thanks, Beryl), and the usual surprises that come into play when renovating an old house. We could not be more pleased with PAR Construction and highly recommend them to anyone looking for high-end renovation/construction work! Now, for more details: We hired PAR Construction to remodel our upstairs bedrooms/closets to provide a room for our three young kids. We interviewed a number of construction companies and ultimately hired PAR Construction because of their demonstrated track record of quality and communication. They delivered in every way, and then some! As soon as we put the initial deposit down, Adam and team submitted the plans for permitting approval, which can take some time. We were provided regular updates throughout the permitting process and Adam and team responded quickly to any follow-up requests from the folks at the permitting authorities. As soon as we got the all clear from permitting, Adam and his team (shout out to my guys Gabriel, Raph and Felix – miss y’all!) sprang into action and began work right away. They came and worked every weekday, and regularly on Saturdays as needed. They were kind, courteous and diligent in carrying out the project. It can certainly be awkward to have a group of seemingly random people in your house on a daily basis, but the PAR Construction team did a great job minimizing disruption and were mindful of keeping our home as orderly as possible. It got to the point that I looked forward to chatting with the team every morning before work and catching up at the end of the day. We had a great experience with each member of the PAR Construction team and I am confident in saying it doesn’t get any better than them! PAR Construction is not cheap, but the cost is excellent value for their top notch work. Like any construction project, there were some additional costs that came up as the project carried on (i.e., moving some 100 year old cast iron pipes that we didn’t know existed in order to make room for a new beam, etc.), but any potential added costs were communicated on a timely basis and we were given the option to accept or decline the updated work/cost. The original bid/scope of the project was meticulously laid out and PAR Construction stayed true to the cost of the original plans. As noted above, the perils of Hurricane Beryl tried to interrupt the progress on our home, but the PAR Construction team didn’t let that stop them. Even though we were without electricity for over a week, the team showed up every day and continued working to keep the project on schedule. In addition, we had a leak develop in a downstairs side room during the hurricane, and the PAR Construction team helped address the leak and replace/repair the components of the ceiling as needed. I am very thankful we had Adam and team to help address the issue promptly, before it turned into a bigger issue! Sure, you might find other companies that will give you cheaper bids for your project, but I am confident that PAR Construction will blow them out of the water in terms of quality of work and value for your money! Adam is an honest and genuinely kind person, and those qualities were extremely important to me in deciding to hire his team for work on our family home. My family and I are very pleased with the outcome of our project and look forward to hiring PAR Construction for additional work in the future."

FAQs for basement remodeling projects in Katy, TX

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
