"Had a 5 foot long crack in my poured-concrete basement wall. It was not leaking, but I wanted to have it sealed regardless. Alek came on a Saturday, gave me his estimate, and then repaired the wall. He was very forthcoming by explaining that the repair was not absolutely necessary if there was no leakage, but I wanted it sealed anyway. He did a top rate job and I would not hesitate to use his services again."

"Before the work began, the owner gave great advice on what would look good together without pushing any product. The work started on time and finished early. Everything was done with excellent workmanship. It turned out better than expected! Upon completion, everything was cleaned up extremely well and I didn't have to do any cleaning myself."

"I hired Beautiful Home Services for a master bathroom renovation after reading many positive reviews posted online. I'm giving BHS 2 stars because even though I'm happy with the final outcome, it was a series of struggles over the course of 6 months to get here. Leading up to the renovation, I had 2 different project managers who were supposed to be helping me pick out materials. Neither sent suggestions or responded to my emails about selections for my bathroom. In the end, everything was set up by an assistant. I finally got a 3rd project manager, who showed up to my project on what was supposed to be their start date (it had to be pushed back a week) with no idea of the plans that had been in progress for months. This situation quickly went from bad to worse due to a ton of miscommunication between my contractor, the 3rd project manager, and the BHS offices. My contractor continually lied about things to me and to the BHS office. They tried to charge me over $1,000 for a mistake the contractor made. The contractor even tried telling my project manager I approved of the mistakes, which I obviously didn’t. The day my project manager scheduled for my countertop to be installed, the contractor was nowhere to be found, which resulted in delays lasting weeks. He also started to treat me in an incredibly condescending manner. I'm a single woman who was very involved in the project (I built the custom vanity myself) and he treated me like I had no idea what was going on despite my having to essentially act as my own project manager for the entirety of the renovation. I gave him multiple pictures of how pieces should be installed, and his team disregarded them and installed the pieces incorrectly. Ultimately, I complained to the project manager about him, who took him off the job. On their last day of work the contractor still showed up to my house, even after being told not to. There was also an issue with water being spilled upstairs in the bathroom. I was told by the contractor that I would come home to a "small brown spot" on my kitchen ceiling where the water spilled on the floor above. Instead I came home to a hole in the ceiling, with water actively leaking (see attached picture) onto my kitchen floor. He downplayed this to the BHS offices too, who didn't know how extensive the issue was. Thankfully they fixed everything without charging me. This project started in November and was finally finished in April. I was waiting on a piece of hardware for my shower that I notified my project manager about in January. Unbeknownst to me, he left the company and did not relay this information to my now 4th project manager. Contractors came by to finish the project in March without knowing there was still a piece missing. At this point, I contacted the BHS owner and expressed my frustration with the entire project, but mostly how long it was taking. He apologized and let me know he would make this project a priority, and try and order the missing pieces for the hardware ASAP. 3 weeks go by and I only get 1 piece of the 4-piece hardware. Finally, the 4th project manager tells me they’re out of stock and I should pick out something new. I quickly googled the entire piece of hardware (not each of the 4 pieces), and found there were over 300 in stock at Ferguson, which is the supplier BHS was working directly with. I have no idea how a project manager, an owner, and the multiple representatives at Ferguson couldn't find this piece when they told me my project was a priority, adding an additional month to this already extremely delayed project. I would absolutely not recommend BHS to anyone planning on renovating their home. This was a horrible experience for me and not worth the time and undue stress for a master bathroom renovation."

FAQs for basement remodeling projects in Knoxville, MD

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.
